Automated Education Project
System Development Corporation
Santa Monica, Calif.

The System Development Corporation has conducted an active program of research in automated
education for the past three years. Initial experiments
were performed with an instructional system controlled by a Bendix G-15 computer. \;\Tith this computer-based teaching machine, various branching techniques were studied with some six hundred students
acting as experimental subjects.
More recently a new facility, designated CLASS
(Computer-Based Laboratory for Automated School
Systems), has permitted members of the Automated
Education Project staff at SDC to broaden their scope
of research. The investigations have included both
experimentation with optimum sequences of educational materials for individual student instruction,
and development of a computer-assisted school system which makes individualized education feasible.
The new laboratory, a part of the general purpose
Systems Simulation Research Laboratory at SDC,
utilizes a Philco 2000 computer to provide highspeed data-processing assistance to many parts of a
simulated educational system.
CLASS permits simultaneous automated instruction
to twenty students in either an individual or group
mode of study. In the individual mode, CLASS operates in much the same way as the Bendix-based system.

Adaptive Control over the Individual Student
The first teaching system used by the SDC staff is
shown in Fig. 1. The Bendix computer, operating
under program control, transmits instructions to a
Random-Access slide Projector (RAP) Model 600 for
the selection of one of six hundred slides held in storage. The sequence of slides seen by the student is
determined on the basis of the student's response to a
single question, or to several questions, or on the basis
of the time interval between presentation of material
and response. The student receives feedback messages
through the computer-controlled typewriter keyboard
or by means of addi tional slides.
Prior to an experimental run, the G-15 is programmed for its teaching functions by input of a perforated paper tape. The instructions on this tape
represent decisions in regard to type and sequence of
educational "items" to be selected for each student on
Ihe basis of his overt learning behavior.
The G-15 sends four signals of four bits each to the
Projector Adapter; three of these signals set the stepping switches which record the computer's instruction
to Ihc RAP GOO. The first signal clears the relay regisIeI' o[ any previous information. In addition to these
signals, there is an interlocking feedback control which
prevcnts changing of instructions while the system is
in operation. It takes the G-15 about Gjl 0 of a second
6

/

to transmi t to the RAP 600 the full command for a
slide selection.
A sample teaching machine lesson used with the
Bendix G-15 is given in Appendix 1. Although actual
lessons are longer and generally more complex than
this one, this sample does illustrate a number of important facets of the lesson design. Some of the instructional items branch the student to remedial paths
designed to correct particular errors. At two points in
this lesson, decisions are made on the student's cumulative error tallies. At these points, additional instructional items are given to the student if he is
experiencing difficulty in learning the material. At
the end of the lesson, a self-evaluation item is presented to students who have made at least one error.
This gives the student the choice of deciding whether
or not he needs more instruction.

The CLASS Facility
Use of the Philco 2000 computer in the new laboratory enables the researchers to teach twenty students
in several modes of automated instruction-an individual mode, a group mode, or a mixed mode in which
some students study independently while others work
in small groups. Except for classroom space limitations in our laboratory, the Philco 2000 could instruct
some three hundred students in the individual mode
with each student seeing a different sequence of instructional materials adapted to his particular needs.
In the group mode, this number of students instructed
could be 900.
For individual instruction, a manually operated film

viewer serves as the output source. A student, working independently, makes multiple-cho,ice response~
on the response unit keyboard (see the front cover of
this issue). The computer is programmed to analyze
these responses, signal the correct answer on the response keyboard, and instruct the student where to
proceed next by way of a four-digit read-out panel on
the response unit.
Automated or semiautomated group instruction can
be effected by using the RAP 600 or teacher-controlled
audio-visual projectors for generating a common stimulus display over the large closed-circuit TV screens
in the classrooms. As seen in Fig. 2, students in CLASS
are learning in the group mode.
The teacher will have five sources of information
available with which to watch and check student learning behavior or call up information on individual or
group performance. These components are: (1) a
teacher's console with automatic alarm lights, corresponding to each student station, alerting the teacher
to students who are not meeting predetermined criteria
programmed in the computer; (2) a read-out panel,
similar to the student response device, making it possible for the instructor to monitor a specific student;
(3) a remote-control panel for sequencing and controlling audio-visual materials; (4) a film viewer for
following the educational program; and (5) an educational data display, generating performance or historical data directly from the computer memory drum.
To study the application of data processing methods
in other school functions, special areas are available
in CLASS for administrative and counseling functions.
A teletype unit in the counseling office will aid the
counselor in preparing daily scheduling programs and
conducting interviews, and will generate displays to
aid the teacher in classroom management. Automatic
referrals will bring students to the counselor before
serious educational problems are encountered.
For administrators, a 900-line-a-minute high-speed
printer, operated either on-line or off-line, wi~l supply
immediate information on the state of academIc knowledge of each student. Less urgent reports necessary for
scheduling, curriculum planning, budgeting and logistics can be retrieved when the computer is not selecting and analyzing instructional programs.
A 'real-time switch and storage transducer, which
permits coupling human inputs to and outputs from
the computer, has been developed by SDC engineers.
This machine is capable of recording in the computer
some 4,000 input signals ten times a second. The machine also permits distribution of 4,000 output signals
to the simulation area every 1/10 second. A plugboard
for rearranging the receptor and effector connections
to computer memory locations is also included.

Programming for CLASS
Computer programs written for this project fall
into two broad categories: the lesson assembler and
the instruction control program. The lesson assemblers resemble, in both structure and function, the
typical computer compiler-assembler. The instruction
control program, called i\f ell Lor :WOO, has many of the
characteristics of the usua I process control programs.
Lesson assembly programs for CLASS are designed
to generate a magnetic tape that contains a complete

'l'IlC prilllary language to be used for the CLASS
C()lIlpUler program will be JOVIAL, a general-purpose
programming language initiated at SDC. It is a readable and concise language, utilizing self-explanatory
English words and the familiar nota tions of algebra
and logic. It has been found especially suitable for
problems requiring an optimulll balance between data
storage and program execution time.
Besides, JOVIAL is a machine-independent programming l'anguage and can serve as a m~ans of realizing a stated process on a llulllber of dIfferent computers.

The Future School Systelll and New Technology
CLASS development has recognized that the most
practical and immediate need for a computer in our
educational systems is probably to automate paperwork, a prosaic function in school, but we foresee the
future role of the computer in education to be more
than that of bookkeeper. The evidence for this projection lies in some of the recent developlllcnls in COIllputer technology:
(1) The computer-based Icaching- llIaciline \Vi~I,1
the potential for handling individual studel~t ddferences in learnillg ra Ie, background, and apu tude;

those in business which supply periodic economic
forecasts, balance budgets, and plan financial strategies;
(-1) New techniques for processing educational
data such as real-time registration and scheduling
programs, counselor and teacher data displays, automated diagnostic interviews, and testing routines.
The application of the digital computer to eduGttional functions holds the potential of an importan t
technological breakthrough in a field that has been
remarkably resistant to change. With more students
to teach, fewer teachers, and an increasing portion of

the working population to retrain, educators are being
pressed in the direction of automation.
The question whether school systems can afford the
large general-purpose computers currently being marketed would in many instances have to be answered in
the negative. But the development of the special-purpose computer with multiprocessing, time-sharing capabilities is on the horizon. It would be short-sighted
to delay the rcscarch until the hardware is available.
As new uses arc cxplored and computers are designed
with educatiollal functions in view, many school systems will joill thosc pioneers who have already made
the leap into thc modern technological world.

111 the teaching machine field, although onc hcars
statements that "the devices problem has bccn soh'cd,"
it would appear that the tremendous spccd alld vcrsatility of modern day computers can nevcrthcless hc
used most profitably.
A great deal of the current research in the developIllent of new educational techniques has been in thc
area of teaching machines. l\IIost of the contributors
in this area up to now have been psychologists intercsted in applying their theories of the psychology of
learning to new teaching techniques.
Now, the opportunity for contribution by the designers and programmers of computers is fast approaching.
Basically, present day teaching machinesl,~, 3 present a subject to a student in short incrementseach increment being followed by a question. These
increments (hereafter referred to as "information
blocks" or just "blocks") may be anywhere from a
sentence to a paragraph in length and may contain
pictures, diagrams, and even auditory information.
They are presented to the student in long sequences
called teaching machine programs (not to be confused
with computer programs); these sequences are constructed in such a way that 'the student is led in an
easy and straightforward way to eventual mastery of
the subject matter.

COMPUTERS and AUTOMATION for February, 1962

illclllde sclf-paccd instruction and immediate evaluaI iOIl for I he sllIdcnt of his answers to the questions,
ele.; bill thc illlportant thing to remcmber is that we
are first alld foremost interested in the development
of tcchniqucs that will "teach better." Since one of
thc best tcaching methods that we know today is the
human tutor, a logical approach to automated instruction is to try to simulate as many properties of a
human tutor as possible; and indced, this is the criterion commonly uscd to dcscribe the advantages and
indicate thc vast potcn tia I of teaching machines. Two
very importallt propcrtics of the human tutor, however, arc prcsenl in only a very limited degree in the
teaching machines currcntly in vogue; these are adaptability to thc studcn t and systematic improvement
with expcricncc.

Student Adaptability
A dcsirable feature of any tutor or teaching machine is that it be able to react to differences among
students and adapt its presentation to the individual
learning characteristics of each student. For the tutor
or machine to do this implies a decision process that
uses some known past history of the student to decide which presentation of the material is likely to
be best for him; and this dccision proccss is no less
important for a teaching machinc than for a 111101'.
The process of providing dillcl'elll leachillg lI1achine
programs for difrcrcnt stlldenls is called "brallching."
One of thc II10St cOll1l11only uscd mcthods of branching is thc "intrinsic programming" of Norman Crowdcr! in which thc IICXt hlock presented to the student
is dctcrll1illcd hy his answer to the last question. A
lIalllral cXlcllsion of this method is to base the decision
on thc en/if(: /)(Isl history of answers of the student too

thc tcaching program; a structure for such a decision
process is the subject of this paper.
Systematic Improvement with Experience
When a tutor is good, we expect him to become
better at his job as he teaches more and more students.
The same property is a desirable one for a teaching
machine. At the present time this property is available in teaching machines only through the improvements that the researchers make in their teaching ma" chine programs. Improvements in the teaching machine programs are, of course, desirable, but a method
for systematic improvements in the quality of the
branching decisions is also needed. A good teaching
machine should be capable of improving its decision
processes as it "learns" more about the effects that are
caused by the decisions. Thus, we should like for the
next tutoring decision to depend not only on the
present student's past responses, but also on other
available information including the responses of all
past students; in other words, the teaching decision
system should be an adaptive system.
Structure
The class of teaching machines proposed here is
based on a particular structure; the elements of this
structure are: (1) an ordered set of concepts; (2) a
general branching network; (3) a model for estimating
probabilities of responses.

1. An Ordered S{~t of Concepts
Every educator, no matter whether he is a teacher
or a writer of teaching machine programs, must have
Sample
Path No.1

a set of goals. This is list of things that he is trying
to teach successfully to his students. We shall call
these things concepts, although a very broad definition
of the word concept is intended.
Generally, the educator will also arrange these concepts in some reasonable order so that he can teach
the concepts to the students in sequence. Therefore,
we shall assume that the subject matter to be taught
has been decomposed into an ordered set of concepts.
The question of measurement also arises: How shall
we find out whether or not a student understands a
concept? For this purpose we shall assume that there
exists a set of test questions for each concept being
taught. Answering the test questions correctly is considered to be equivalent to understanding the concept.
These test questions will be given to each student at
the end of his instruction on the concept to determine
how well he has absorbed the subject matter and how
well he understands the concept.
2. The General Branching Network
In order to provide a high branching capacity in
the class of teaching machines discussed here, a large
network of information blocks (see Fig. I) is assumed
to exist for each concept to be taught. Each block
contains information or material that one might want
to present to a student during the course of the instruction.
Each block is identified by two numbers i and j.
The first number i specifies the level or rank of the
block in the sequence of concepts to be taught. The
second number j is a serial number that identifies

the block among alternatives explaining that information. Thus block b(3,2) is block no. 3 in level and
no. 2 in manner of explaining. Some blocks may span
more than one level; in this case, the level number
denotes the first of the levels spanned by the block.
In Fig. 1 the branching network shows in Path I and
Path 2 how two students have progressed through the
branching network. In general, students start at the
first level and travel downward through the blocks
as they learn more and more about the subject material. Generally the same material will be contained
in sequences of blocks spanning the same l~vels; for
example in Fig. 1, b(I,3), [b (1,1), b (2,1), b (3,1)],
[b(I,I), b (2,2)], and [b (1,2), b (3,1)] will all contain the
same information. The presentations, of course, will
be different; for example b(I,3) would present the
information in a much more condensed form than
[b(l,l), b (2,1), b(3,1)J. Alternate presentations of the
same material are also illustrated as in b(2,3) and
h(2,4) of Fig. 1.
Test Questions
At the end of each block there will be a question
for the student. These questions can be used either
as reinforcing agents for conditioning student behavior or as tests to determine the student's comprehension of the information. The answers to each of these
block questions are classified into a finite number of
exhaustive alternatives so that every answer can be
recognized by the teaching machine. Furthermore, it
is desirable that the student be told whether or not
he has answered the question correctly. (One can
also use this opportunity to explain to the student
his likely error if he missed the question.) For this
reason each information block will generally have a
fine or more detailed structure similar to that shown
in Fig. 2.
Student Procedure
The procedure for a student taking the course will
consist of many cycles of the following two steps:
1. If the student is at level i, the teaching machine
will decide which of the several blocks leaving this
level to present to the student.
2. After reading the information in the block that
is presented to him, the student will answer the question at the end of the block. If his answer is correct,
it is assumed that he has absorbed the material in the
block satisfactorily; and thus, he will be placed at the
terminal level of the block and Step 1 repeated. If he
does not answer the question correctly, then the student will be placed at some level less than (or perhaps
equal to) the terminal level of the block in order to
clear up the misunderstanding that caused him to miss
the question.
Thus, we see that a student will wend his way
through the network of blocks proceeding from the
first level to the last with the teaching machine deciding at each level what block to present to the student.
The student's level at the end of each block is determined by his answer to the block; that is, we shall assume that a function v(i,j,k) is given along with the
branching network, and the function is equal to the
level of a student if he gives the kth answer to block
b(i,j).
In Fig. 1 the dotted lines show two possible paths

that students might take through the array. Path 1
represents a student who has given all correct answers
to the block questions, while the student of Path 2 has
missed block questions at b(I,3) and b(3,I).
In any practical application there will be one of
these networks of blocks for every concept to be taught.
Although the emphasis in this paper is on the decision-making aspect of teaching machines, the importance of the actual contents of the information
blocks can hardly be overstated. On the other hand,
the illcorpora tioll of a decision mechanism into a
teachillg machine call make the improvement of the
block cOlltellts easier through the relative evaluation
of alternative presentations of the course material.
3. A Response Probability Estimation Model
In order to decide which of the possible blocks the
student should receive, it is necessary for the teaching
machine to investigate many paths that the student
might take. Each of these paths must be weighted
with the probability that the student will indeed take
that path. This requires a model (see Reference 3)
that will estimate the probability, p(i,j,k), that the
student will respond with the kth answer to the question at the end of b(i,j).
There is a question here of just what is meant by
these probabilities. Here the probability p(i,j,k) that
a student with a certain known past history will give
the ktlt answer to block b(i,j) will be defined as the
fraction of students out of an infinite population of
students with the same identical past history who
would give the kth answer to block b(i,j).
The problem, then, is to find mathematical models
that will use the past history of the student correctly
to estimate the true values of p(i,j,k) as defined above.
The particular elements of a student's past history
that will be used in this estimation are part of the
model. These models will formulate an abstract description of the process whereby a student's past hist.ory determines the value of the abstract probability
defined above. As with allY mathematical model, the
model's description of the process is entirely abstract,
and the value of the model is determined by how well
this abstract description conforms to the n:(/I w()rld
j)l"()CCSS being simulated by the ll)odel.
II

"''".-~

In general one would expect the probabilities to be
closer to 0 and 1 as the past history of the model includes more and more pertinent details about the student. Unfortunately, as the number of such detai1s
increases, it becomes more difficult to use them correctly and the complexity of the computations also increases. Thus, one must face the eventual trade-off
between high uncertainty in the true probabilities on
one hand, and inaccurate prediction and complex
computations on the other.
"V\Te see here an example of how the teaching machine will be able to improve its decision process with
experience. As the number of students that the device
has taught increases, the errors in the probability estimates due to lack of information will generally decrease and the decision process of the machine will
become more accurate.
Decision Criterion
In makillg the decision, the computer must have
some cri Lerion (or utili ty function) to use for deciding
which of several alternate paths through the "blocks"
of subject matter is to be selected for teaching to the
learner. The particular criterion chosen will depend,
in general, on the opinions and goals of the educator
using it. Some possible criteria that might be used are:
nil
1
1
U = - , L = -(na -n\J), or R = --(na -n\J)
N
N
NT
where nil and na are the number of test questions for
tha t concept that the student answered correctly before and after taking the presentation of the material
represented by the path; N is the number of test questions for that concept; and T is the time for the student to read and respond to the material in the path.
An Actual Demonstration
In order to illustrate the structure presented here
and to study its potential advantages, a preliminary
teaching system containing an example of each of the
preceding elements was developed. 'Vhen one considers what is potentially attainable within the structure, the system described here will appear rather
unsophisticated-and indeed, it is. Nevertheless, the
teaching system was applied to instruct 20 students,
and indicated that is was capable of distinguishing
among students, making different decisions for students with different past histories. Furthermore, the
system also changed its decision process with experience.
The physical device was composed of three interconnected pieces of equipment: (1) a microfilm
reader; (2) an electric typewriter; and (3) the IBM
709 digital computer at the M.LT. Computation
Center. The array of information blocks was stored
on microfilm; and the microfilm reader was connected
to the computer so that it could select any particular
frame of the microfilm and display it to the student.
The illst rllction process for the system consisted of
the followi Ilg steps:
1. After giving the student some brief instructions
Oil t he operation of the microfilm reader and typewriter, the computer decided what block to present
to the student first and then cycled the microfilm
forward to the frame that contained the desired block.

Each of these blocks contained a paragraph or so of
information about the course, followed by a question
that tested the student's comprehension of the information.
2. The student wrote his answer to the block question on an answer pad; then he advanced the microfilm reader forward one frame to where a list of
possible answers to the question was displayed. (In
each case, of course, one of the alternatives was a
catch-all for any answer not listed.) Next to each of
these possible answers was a number; the student
entered the number next to his answer into the typewriter an"d then punched the "carriage return" key.
3. Upon sensing the carriage return, the computer
advanced the microfilm to a frame that explained to
the student whether or not he had answered the question correctly; if he had not, this frame also attempted
to explain to him where he had gone wrong. While
the student was digesting this explanation, the computer calculated the next block that the student
should receive. When finished reading the explanation to his last answer, the student was instructed to
punch the "carriage return" on the typewriter.
4. The computer then advanced the microfilm to
the next block and the process was repeated until the
studen t finished the instruction on a particular concept and arrived at the test question(s). The test
questions were given to the student in the same way
as the blocks; the only difference was that all students
received the same test questions.
5. At the end of the instruction the student's responses were used to update the parameters needed
by the system's decision process.
The computer program for this teaching system
used approximately 5000 of the 32,000 registers
available on the M.LT. 709.

Content of the Sample Teaching System
It may be of some interest to report what was the
actual content of the material taught. This was a
miniature (or finite) geometry expressed in the following statements:

a

Postulate 1. There is point.
Postulate 2. Every line is a set of exactly two
points.
Postulate 3. Every point lies on exactly two lines.
Postulate 4. For every line there are exactly
three parallel lines.
Definition 1. If a point P belongs to a set L,
then P lies on L, and L contains P.
Definition 2. Two lines are parallel if and only
if there is no point that lies on
both.
The outcome of the teaching system was for the student to be able to demonstrate two theorems:
Theorem 1. There are exactly six points.
Theorem 2. There are only two models.
(One of the models is a hexagon, with the convention
of the points being the vertices and the lines running
along the edges of the hexagon, and stopping at the
vertices; the other model is two separate triangles,
with the same convention.)
This particular subject was chosen because it is
short, simple, and relatively unknown.

computer, the scientists had the answers to their questions.

The best way to test new equipment is to put it into
actual use. But how can the performance of advanced
airborne guidance systems be evaluated without spending millions of dollars in production and Right test of
equipment? How can the effect of possible design
changes be determined? How much can systems and
equipment be improved before over-all performance becomes subject to diminishing returns?

The IBM people doing simulation studies such as this
have extremely varied backgrounds, mathematics, physics, engineering. But they ha\1~ in common-the ability
to "see" physical problems in mathematical terms and to
solve them by machine computation. For people with
this ability IBM offers the advantages of advanced tech,
nical facilities and widely experienced associates.

Scientists have been exploring these questions-and many
more-at the Simulation Laboratory of the IBM Space
Guidance Center in Owego, N. Y. For example, they
constructed mathematical and logical models of every
factor in a major B-52 air strike. Into an IBM computer
went simulation data on enemy missiles, radar, fighter
defenses, as well as detailed weather and terrain data and
complete aircraft performance parameters. After more
than 1200 simulated battles were "fought" inside the

The teaching system usually (but not always) presented a paragraph of information, and offered usually
(but not always) three answers, of which only one
was the right answer. In other words, it was like the
scrambled book of Norman Crowder (see Reference 1).
Equipment Limitations
Due to equipment limitations, only one student at
a time was taught by the teaching system described
above. This was a tremendously inefficient use of
computer time, since the calculation of each decision
required less than one second of computer time. A
student took from 1 to 6 minutes to complete a block
with 2.5 minutes a typical time. Hence, we see that
over ~)9 per cent of the computer time was spent
waiting for the student to answer a question or finish
reading an explanation. The answer to this inefficiency is either to allow the computer to teach many
students at once, or to allow some one else the use of
the computer during the idle time. A time-sharing
system is currently under development at M.l.T. that
will provide this latter solution to the problem. The
former solution is the natural one for the computerin-a-school situation.
The response probabilities for this teaching system
were estimated by a simple intuitive lllodeJ3 that estimated p (i,j,k) as a function of: 0, the fraction of
correct responses by the student in the past; rfJij(k),
the fraction of students taking b (i,j) in the past who
have responded with the ktll answer; and a, the fraction of correct responses by students to all questions
in the past.
The course covered two concepts containing 12 and
13 levels and 25 and 27 information blocks, respectively. The entire course used 224 frames of microfilm.
Twellty students took the course as taught by the
teaching system. The average instruction time was
53.0 minutes with a range from 33 to 75 minutes.
The total fraction of correct responses was 0.753 with
a range from 0.529 to 0.938.
There were many instances in which the computer
made different decisions for students with different
past histories (for this simple system the entire past
history of the student was con tained in 8, the fraction
of correct responses in the past).
Analysis of Results
These results indicate that the teaching system described in this' paper can (1) make quantitative
decisions in its presentation of the course material to
students so that different students, depending on their
past performance, receive different presentations, and
(2) change this decision process with experience. We
have not proved, of course, that this teaching machine
is a better machine than any other; we have not even
proved that the changes mentioned above are changes
for the better. At this point one must rely on his
illtuitioll to convince himself that a system capable
of makillg systematic changes in its presentation of
lllaleriaI and in its internal decision process must be
a pOlel1tially better teaching device than one without
I hesc advantages.
On the debit side of the ledger there are some
practical disadvantages that should be mentioned

concerning the implementation of an extensive teaching system along the lines of the above comments.
First there is the problem of storage space in the computer. While it is true that the teaching of many
subjects to many students would indeed tax the core
storage requirements of most computers, it should be
possible to employ auxiliary storage such as magnetic
tapes and drums to solve that problem (at a slight
reduction in speed). This compromise plus the technical advances in the future plus the possible advantages to be gained from a mass-produced, specialpurpose tea~hing-decision computer should adequately
solve this problem.
Cost
A more serious problem is the cost of such a teaching system: First of all there is the cost of the computer; but when one considers the reduction (in
dollars per instruction hour per student) that should
be achievable with special-purpose, mass-produced
computers capable of teaching many students at once,
the cost restrictions from this source become less
severe.
A more significant chunk of the cost dollar will go
toward the writing of the information blocks. This
is admittedly a tougher job for the system discussed
here than for the usual straight-line teaching machine
programs, since there arc two to three times as many
blocks to write. However, the computer may be able
to help with this problem-first, by providing relative
evaluations of alternate presentations of material (as
in b(2,3) and b(2,4) of Figure 1), and secondly, by
spotting situations in which the addition of blocks to
the branching networks may be advantageous.
On the other hand, if, after all is said and done,
computers are the only way to do the required job,
then the economics of the problem may have to be
subordinated to educational necessity.
The structure defined above has two further applications other than general classroom instruction. First,
teaching systems using this structure could be used
for the evaluation of teaching machine programs. As
an example, one could use the teaching system to find
a preferred pa th through the branching network and
then use this preferred path in simplier, less expensive
teaching machines.
Secondly, this class of teaching machines could find
valuable applications in the area of educational research. Through the use of the wide versatility in the
controlled situation enforced by the system, it should
be possible to conduct research into important educational problems, such as: What are the important
measurements that should be made in the educational
situation? How can the data for a particular student
be used most effectively in teaching decisions? What
is the best simple decision mechanism that one can
use in an inexpensive teaching machine?

NEW CONTROL DATA 160·A COMPUTER
Desk Size Computer with Large Computer Capabilities
In most computer evaluations, the flexibility and capability of the computer to handle input-output operations
is of special importance. No other small scale computer
on the market today has the input-output features that
are standard on the Control Data 160-A Computer.
For example, the 160-A exchanges data with inputoutput devices at any rate up to 70,000 12-bit words per
second. The 160-A also has the capability of buffering
data while computing ... or while the operator manually
enters data (whether the computer program is running
or stopped). This input-output flexibility is combined
with the following 160-A features:

There arc two input-output channels in the 160-A: a
bufler c/1lI1l1ll'1 and a non-buffer channel called the norm{/l C/UIIl II cl. Both can be used simultaneously for any

combination of input-output operations.
During an input-output operation via the normal
channel, computation is halted temporarily while the
operation is carried out. However, once an input-output
operation is initiated on the buffer channel, the 160-A
either continues computation or performs some other
I/O operation on the normal channel.
The Control Data 350 Paper Tape Reader and the
BRPE-ll Teletype Paper Tape Punch-standard equipment on the 160-A-are connected to the normal channel
and are not buffered. Other peripheral devices can be
connected either to the normal channel or buffer channel.
When a peripheral device is connected to the normal
channel, data is transmitted between the 160-A and the
peripheral device via the normal channel only. However,
when it is connected to the buffer channel, data can be
transmitted between the 160-A and the peripheral
device via either the buffer or normal channels. In this
case, the normal channel is utilized at any time the
buffer channel is not engaged.
A desk-size computer, the Control Data 160-A has the

COMPUTER TEACHING MACmNE PROJECT:
PLATO ON ILLIAC
Donald L. Bitzer and
Peter G. Braunfeld
University of Illinois
Coordinated Science Laboratory
Urbana, Ill.

A certain teaching machine developed at this laboratory has been named PLATO, standing for "Programmed Logic for Automatic Teaching Operations."
It is a device for teaching a- number of students
individually by means of a single, central, high-speed,
general-purpose digital computer, in this case the
lLLIAC, the University of Illinois automatic computer. The general struct~re of PLATO is indicated
in l'ig. 1. For simplicity, only one student is represented in the diagram. The central clement of
PLATO is the high-speed digital computer.
Each student communicates with the computer by
means of his own keyset, which can be provided with
up to G1 keys representing a full complement of alphanumeric characters. When asked to answer questions
posed to him by the machine, the student's answers
may thus take such varied forms as numerals, algebraic expressions, and words or phrases.
Special keys enable the student to control the presentation of material to him by the machine. The
machine communicates with each student by means of
closed-circuit -television. Material is presented in two
different ways:
(I) The machine presents static textual material
by commanding an electronic switch to connect the
video output of the appropriate slide to the appropriate student's display.
(2) Dynamic non-textual material, or material furnished in the course of instruction (such as student
answers), is written by the machine on the student's
TV display tube by means of an intervening buffer
storage tube.
For multiple, student operations, a keyset, television
display, and intermediate output buffer storage device
(Electronic Book)

are provided for each student. The central computer
and slide selector, however, need not be duplicated;
they serve all students on a time-shared basis.
It appears to be important in multiple-student operations, to require the condition that no student shall
be aware of any other student's existence. To meet
this condition, we are requiring the computer to respond to any student's request within 200 milliseconds.
The general logic by which instruction takes place
is indicated by Fig. 2.
Textual material is presented on a sequence of
slides. \Vhen the student has finished reading a given
slide, he may proceed to the next slide by pushing the
"continue" button on his keyset. Similarly, if he desires to review ,material contained on a previous slide,
he may do so by pushing "reverse." On certain slides,
questions arc posed to the student. He cannot "continue" beyond such a slide until he has successfully
answered all the questions theron. As the student
types in his answer, the machine displays it-character by character-in the space provided for the answer
on the slide. As soon as the student indicates to the
machine that he has completed his answer, the machine responds by indicating "OK" or "NO," depending on the correctness of the answer. The student
may continue to punch in revised answers until the
machine indicates that the answer is correct.
H the student indicates to the machine that he
needs help in answering the question-by pushing
the "help" button-the machine jumps to a "HELP"
sequence appropriate to that question. In this sequence, further relevant textual material, if necessary,
is presented, and the original question is broken up
into a series of "easy" subquestions, designed to lead
the student stepwise to the solution of the main question. A student need not complete a help sequence.
At any point in the help sequence, he may indicate
to the machine his desire to be confronted once again
with the original troublesome question by pushing the

this question properly, leads to a return to the help

where a student should feel it necessary to ask for

You see our master control program wasn't patched
up to fit the computer. We designed the computer to
fit a carefully thought-out master control. This is the
secret of the built-in operating system's unmatched
flexibility and efficiency. It does all the things we
mentioned in our 5th question and also permits
the addition of new equipment and programs.
Another thing: The B 5000 can process programs
written in COBOL or ALGOL-but that's a story
in itself. If you would like the details on all the

A Burroughs B 5000 is your answer to all these
questions. Take multiple processing. We define it
as "priority processing on a time-sharing basis."
This is the way the B 5000 is normally used. When
you want to feed in another job, the B 5000 does
not need additional instructions for sequencing and
scheduling. It has its own master control program
that does scheduling automatically. The programmer doesn't even have to specify the components
to be used. He just feeds in the new program. Any
time. Usually while other jobs are processing. The
master control will integrate it into the work load
and see that the components operate at maximum
efficiency. The human error factor in scheduling is
virtu,ally eliminated.

And your work load can't outgrow the B 5000.
It's the only computer on the market that can

reprogramming. Thus equipped, the B 5000 can
solve several problems absolutely simultaneously;

the problem, whether his solution is correct or incorrect. In the latter case, the machine can indicate
"NO" without in any way revealing the correct solution.
5. To test the versatility of the machine as well as
the basic logic of the computer program, a number of
instructional sequences have been prepared ranging
from topics in mathematics (such as the elementary
theory of congruences) to instruction in computer programming. To change machine instruction from one
subject-matter to another requires only replacing slides
in the slide selector and giving the computer an appropriate set of parameters.
A study using the machine to teach high school students the binary and other non-decimal number representations has been completed. Post-tests given the
students participating in this study indicated that they
had been able to learn from the machine. It also provided useful information on data-rates-considering
the teaching system from the standpoint of an information processing system.
Studies on teaching students computer programming

COMPUTER MARI(ETING TRENDS

SOME COMMENTS

Norman Statland
Vice President
Charles W. Adams Associates, Inc.
Bedford, Mass.

Historically, the commercial use of computers passed
the tenlh anniversary mark only in 1961. Those familiar with general-purpose digital computers and their
applications have witnessed the progress and increasing spccd of central-processor equipment from electrostatic-tube memory devices through delay line
storage to the predominance of magnetic core storage. Most recent developmcnts point toward the use
of thin-film deposits for faster memories. Similar increases in the speed of photoelectric card readers and
pa pcr-ta pc readcrs, as well as new techniques for
highcr dcnsity Illagnctic tape recording, have combincd to incrcas~ thc potential speed of computer
systems. With these more powerful systems have come
a lowering of unit cosls of data processing and a second generation of computer marketing directly concerned with software programs and advanced logical
design features for the central processor.
In the production of second-generation solid-state
computers, a new breed of equipment manufacturer
has appeared on the marketing scene. Being small,
these companies cannot hope to compete with the
largest concerns. Rather, what they produce has ap18

peal to the more sophisticated users of electronic data
processing systems. They sell their equipment at a
potentially lower cost for each unit processed, but
they leave almost entirely to the customer the organization of the installation, the development of complex
software programs, and the provision of on-site assistance. The advent of this group poses the interesting
question of what trends the computer market will
follow during the decade of the Sixties. To this no
firm answer can be given but some conjectures can be
made.
It is quite possible that the computer industry may
follow the course which developed in the automobile
industry about fifty years ago. During those early
years there were many manufacturers of "horseless
carriages." Some grew large, others remained small,
while many withdrew from the fiercely competitive
race or were absorbed by bigger companies. In time,
the Big Three emerged. But there always were-and
still are- independent manufacturers offering a limited number of models to a specialized segment of the
market. These companies, all relatively small, are
among the first to adopt new design features; they

THE COMPUTER'S ANSWER TO ·A LONG·
STANDING COMPUTER ISSUE.
For a decade East Coast and West
Coast computer designers have
been using different methods of
representing computer logic-the
Easterners with diagrams, the
vVesterners with equations.

L6SMI=

u.-)(A))(L~AZ. *)(LFCA *)

+ (LXA I) (LXA2.)(LFCA)

lFCAJ=

(L~J\f)(L~A2.)

lfCAK =(LXA '~)(L)(A2. %)
In the example illustrated here, the
diagram and the equation tell us
exactly the same thing. Either represents a serial full adder where the
sequence of pulses at the output,
LBSM, will represent a serial binary
number that is the sum of two serial
binary input numbers occurring at
LXAI and LXA2. (The asterisks
indicate binary complements; for
example, whenever LXAI is energized LXAlll1< is not, and vice versa.
LFCA is a carry flip-flop.)

There are persuasive arguments on
both sides. Eastern proponents of
diagrams point out that the logical
interconnections can be seen at a
glance and followed through any
number of stages by eye. The logical
structure of an entire system can be
understood from a diagram more
directly and intuitively, they maintaii1, than from a set of equations.
The \Vestern argument for equations goes like this. It's not true that
diagrams communicate better to the
viewer's intuition, except at first
exposure. The human mind is highly
adaptive. After working analytically
with the equations for a while, the
mind begins to operate intuitively
in that symbology. Then the intrinsic superiority of equations over
diagrams begins to make itself evident. One advantage, say the
Westerners, is that equations can
represent the same information
more compac.:lly and efficiently, as
our illustration shows. Another is
that equations lend themselves better to computer manipulation of
logical design information.
As evidence of the latter advantage
Westerners point to a recent
achievement of some Litton Systems
people: a completely mechanized
procedure for translating logical
designs into wiring lists, including
operational simulation of the design
to verify its accuracy. A procedure
enormously facilitated by the computerizability of logical equations.
It's easy to picture the benefits in
cost, delivery schedules, reliability,
price. Using only a partial development of this method Litton Systems
recently brought a major computer
system from concept to operation
in less than a year.

Now under consideration at Litton:
a machine that will accept as inputs
a supply of standard computer
components and a set of coded
specifications defining the logical
functions desired, and will crank
out completely fabricated systems.
Maybe you think we've loaded the
arguJrwnt in favor of equations.
You're right. But we're ready to listen to arguments on either side.
Drop us a card. Or better still,
drop in in person. You'll like the

imagination-stretching atmosphere
generated by Litton management's
appreciation of the rewards of creative controvcrsy. We have a few

led in the recent introduction of the American compact car.
The trend in the computer industry shows a close
correlation. In it there are today large corporations
producing a wide range of equipment for the complete market spectrum. There are also at least a halfdozen smaller computer manufacturers who generally
offer no more than one or two models aimed at specific
installations.
The activity of this segment of the marketing group
is evidenced by Digital Equipment Corporation's introduction of high-speed and low-cost computers for
primarily scientific applications, and the emulation of
this development by Advanced Scientific Instruments,
Computer Control Company, General Mills, Packard
Bell and Ramo-\I\T ooldridge. \"'hile some may argue
with this rather arbitrary selection, the fact remains
that these organizations have presented machines of
small binary word length having fast internal speeds
coupled with attractive pricing (under $4,000 per
month average rental), in order to gain a place in
the computer marketing race. It is true that the larger
companies have entries which may compete directly
with the machines of these smaller firms; but one
must recognize the quandary of their sales people in
first selecting a system for a prospective user and then
gathering enough arguments to outweigh either the
price or the speed advantage sometimes enjoyed by
the competition.
It is perhaps in the area of support, machine backup
and software and other intangibles that the public
image of a corporation is most important; yet it is
probably the most difficult to comment on since each
case must be treated independently.
One large manufacturer, International Business 1\Ilachines Corporation, presently occupies a dominant
position in the electronic data processing industry.
The other companies appear to be somewhat behind,
except a few small ones which are seemingly coming
along well and show promise of offering performance
figures that are quite admirable for young boys com-

peting against grown men. One cannot help wondering how many others are going to cast themselves in
the role of David engaging Goliath in combat with
only a small stone in the sling. Yet every time that
everyone agrees it takes around ten to fifteen million
dollars to get into the commercial marketing and
manufacturing of EDP equipment, some new small
organization turns up and begins to distribute marketing information and literature.
On paper, each of the newly-designed computers
competes very well, especially in price, with its adjacent competition. Most if not all manufacturers have
found, however, that price is not the only key to the
sale of equipment. Some of these low prices can continue only if the manufacturer considers the develop·
ment of software and a large sales staff as luxuries
not required by its particular type of prospective customer. Following this pattern, such companies as
Control Data Corporation and Digital Equipment
Corporation have been successful in producing and
selling small computers to a limited segment of the
market.
On the other hand, there are companies such as
Burroughs, National Cash Register, Remington-Rand
and Royal McBee, to name only a few, which have
long been in the data-processing business and evidently
feel that to maintain their competitive position they
must stay in the computer race. These manufacturers
have extensive sales staffs and in varying degrees have
endeavored to compete with IBM in the development
of software for their various systems. Likewise, Bendix,
General Electric, Minneapol,is-Honeywell and Radio
Corp. of America, all large corporations, have ventured into the hardware production battle with the
hope of reaping profits from what promises to be a
multi-billion dollar industry during the next ten
years. All have already learned, however, that considerable manpower and money must be invested be[ore even a glimpse of adequate return can be realized.
Because of its many installations in active operation, IBM's library of software programs still exceeds
that of any of its competitors. This is not to be construed as an endorsement of IBM software as superior
or more applicable to a particular situation than anything produced by others. It is simply a statement
intended to suggest that one way to whittle a giant
down (assuming this to be desirable) is by flanking
rather than frontal attacks, so to speak. To increase
their competitive position, it might be well for companies which have entered the EDP f.eld during the
past ten years to consider the desirability of c~ncen­
trating their efforts-design, production, programming and sales-on specialized equipment areas. By
so doing, they could eliminate some needless expense
in areas where they do not have much hope of competing successfully.
_
Recognizing that the initial expenditure will cover
only a limited amount of research and subsequent
program support, there is mounting' evidence to
strengthen _the contention that a more li"mited approach to the marketing of selected system~' rather
than an entire range of systems seems the logical
course for those organizations to follow if they desire
to c?ntinue as successful. producers of equipment.

1415 Providence Highway
Norwood, Mass.
This company has developed a new high
speed analog-to-digital converter which can
give 500,000 complete 10-bit conversions per
second. Output is either serial (5 million
bits per second) or parallel straight binary
(500,000 words per second). Accuracy is about
1/10 of a percent, plus or minus one-half of
the least significant bit. The Model AD-lOA
can be operated internally or externally for
sampling command. This converter has 12
plug-in panels with the 10 logic panels directly interchangeable.

This company has developed a new technique, for high-speed transmission of data
over ordinary telephone lines at rates up to
15,000 words per minute. This is equivalent
to 150 different teletypewriter messages
transmitted all at once.
Alphanumeric characters are coded into
phase relationships among simultaneously
transmitted tones. It makes use of a new
phase modulation technique that makes the
possible number of symbols that can be generated astronomical in magnitude. The differences between the very few characters in the
English alphabet are great enough so that
automatic character recognition is almost
error-proof. It also gives DEFT an exceptional resistance to interference, noise,
and jammings.
The character-recognition technique does
not require either dynamic logic or storage
circuitry.

This company has developed a plug-in
magnetic-core memory array, which can be used
individually or in groups to provide information storage capacity in a large-scale digital
computer.
Usually when there is a malfunction in a
conventional memory array, four to eight hours
are needed to remove it, install a new one,
and resolder. But this plug-in memory can
reduce time for changing from a faulty memory
to a properly working one to 15 minutes.
Since down time for a computer may cost over
$400 an hour, the saving is considerable.

A new size 11 analog-digital encoder with
small size, long life, and high conversion accuracy, is now being produced by this company.
The conversion accuracy is plus or minus 27
minutes. It has 256 counts per turn, and operates at temperatures ranging from minus 60
degrees to plus 180 degrees Fahrenheit.

A typical configuration of the 7040 contains a card read-punch, high-speed printer,
and low-cost magnetic tapes. A basic system
could be expanded in stages to include highspeed tape drives, magnetic disk files and an
on-line IBM 1401 data processing system. A
typewriter built into the computer's console
will print messages during testing and "debugging~ of programs.
Advanced modular design makes available
hundreds of computer configurations built
around the two new central processing units.

The rapid-access storage capacity of the
Univac 490 Real-Time Computer and the 1107
Thin-Film Computer will be increased by an
additional 700 million bits with a new massmemory disc file. This memory can include
up to 24 identical storage discs per unit.
Discs are rotated at a rate of 900 RPM. Data
can be stored on both sides of each 39-inch
diameter disc. Each disc face accommodates
768 recording tracks which are arranged in
six groups or zones. Six data read-write
heads (one for each zone) are aligned with
each disc face. Fully-transistorized read-,
write-, and selection-circuits connect the
magnetic heads with appropriate logic circuits in the system.

ITT has developed a transistorized,
lighter-weight distance-measuring equipment
(DME) to meet the "pinpoint en route" guidance needs of super-speed commercial aircraft .
The new model has 10 electron tubes and
weighs only 29 pounds. Earlier versions, now
in service, have 33 tubes and weigh 34 pounds.
The elimination of 23 electron tubes and their
associated circuitry enables the transistorized
model to operate at cooler temperatures.
DME enables a pilot to read from a dial
his exact distance in nautical miles from a
selected ground station in the nationwide
check-point network operated by the Federal
Aviation Agency. Th,= equipment furnishes important in-flight information reuarding arrival schedules and holding patterns and is said
to be a major advance in aviation safety.

determine the amount of radiation from external sources delivered to cancer tissue and surrounding normal tissues, and the distribution
of radiation by radioactive needles and seed
implants.

functions are: vehicle tracking; data reception and recording; and satellite command
and control.
The nerve center of the tracking station
is the Data Acquisition and Processing Center.
Among the instruments in use there are the
PAM/FM telemetry, IBM 1604 computer, and a
storage and dissemination device called PICE
(Programmable Integrated Control Equipment).
The 1604 computer performs normal computer functions.
PICE, an electronic "storage cabinet",

COMPUTER APPLICATION IN AIRFRAME INDUSTRY

p

A computer has been applied to cut in
half the time required to process parts catalog changes for Convair jetliners. This application is by General Dynamics/Convair,
San Diego, Calif.

C --

The heart of the system is a master list,
which contains detailed information about each
of more than 50,000 parts in each Convair jetliner. When a parts change decision is made,
writers make the required revisions on a
master work sheet. The data processing department, using IBM 1405 and 705 computers,
process, analyze, and reassemble the change
data.

A:

Detailed parts information formerly was
contained on almost one million key-punched
cards. They have now been converted to magnetic tape. Instead of 30 days to process
parts change transactions, which average
about 2500 each day, the computer system will
need only 15 days.

that electronic computers may be useful in
automating legal research. The first field
being studied is merger and monopoly cases
arising under the Anti-Trust Laws.
A "'special electronic legal language"
has been developed for the retrieval project.
Using this, a researcher may ask the computer
to provide a list of citations for all the
cases fitting certain descriptive specific
terms. Or,the researcher might ask for citations, pleadings, briefs, or motions related
to a specific type of merger or monopoly AntiTrust Law case.

at Weston Junior High in conjunction with the
"Madi son Proj ect," an experimental mathematics
program. Since then the IBM 1620 has been made
available to students at several schools and
universities. At Fairfield University it was
used for teaching programming techniques and
also for improving methods of teaching logic
at all class levels, freshman to senior. At
Bridgeport University, the computer was used
as an aid to developing a regular college
course in computer technology. Staples High
used the machine to learn the fundamentals of
programming. And at Joel Barlow High School
the use of computers ill the fields of mathematics and science was demonstrated.
The purpose of loaning the machine is

A Clary DE-60 computer has been introduced as part of the totalisator service at
Santa Anita Racetrack.
The new computing system, developed by
the Clary Corporation of San Gabriel, Calif.,
saves time and increases accuracy in the determination of prices paid on winning horses.
This system is a prelude to installations
expected to be made in 15 to 20 major race
tracks in the country. A second system has
been completedj four others are under construction.
The computer performs the necessary computations during the minute or so each race
is being run. The system has a decoding device which scans the totalisator board and
converts the pooled figures into the numerical system used by the computer. State and
track percentages are deducted automatically.
As soon as the winners are announced, the
numbers of the win, place and show horses
are punched into the computer and calculated
within a few seconds.
HIGH SCHOOL GIRLS USE COMPUTER
AS PART OF CLASSROOM WORK
At St. Vincent Ferrer Catholic High School
in New York City, 400 girls are using, experimentally, a general purpose electronic computer as part of their regular classroom work.
The project is being carried out jointly by
the school and Royal McBee Corporation, Port
Chester, N.Y., which has provided the computer -- a Royal Precision LGP-30.
Du~ing the initial period of instruction
the high school is putting one hour of introductory electronic data processing into the
first semester mathematics courses. In the
second semester, the computer will be integrated into the curriculum and, for those
who so elect, 80 class hours will be devoted
to the programming and operation of electronic
computers.

Among the objectives of this experiment
are: (1) to determine at what point th e
electronic computer can be effectively and
desirably introduced into the high school
curriculumj (2) to study the value of the
electronic computer as a tool of teaching and
learning in mathematics and science areas at
the high school levelj and (3) to explore
the extent of interest of young women in
electronic computer operation and programming

AIRBORNE COMPUTER CONTROLS THE
MANAGEMENT OF JET ENGINES
A computer-controlled instrumentation
system to simplify the "management" of jet
engines and improve the efficiency of jetpowered aircraft has been developed by The
Bendix Corporation of Teterboro, N.J.
Its basis is this: an advanced digital
computer scans all engine functions at a rate
of 2Yz times a second. The system "feels the
pulse of an engine". The computer automatically decides which engine is in need of corrective action and displays its characteristics on a single set of indicators.
Thus, in the test aircraft, instead of
36 indicators to present 36 conditions of engine performance, there are only 10 indicators
to present 80 conditions of engine performance.

"why we chose the NCR computer"
Hycon Manufacturing Co., Monrovia, California
"We chose the NCR 390 Computer for three basic reasons:

"ONE ... Dealing primarily with government contracts, we
have daily need for the ability to get our accounting and
statistical data quickly organized and recorded in a visible
form for ourselves and government personnel to utilize.
Since the NCR 390 is a computer which employs conventional business-type records, it will permit us to accomplish
this first requirement in an extremely fast, efficient, and
economical manner.
"TWO ... It is absolutely essential that our records be accessible, sometimes for years, for audit and reference by
ourselves as well as government person!lel. With the NCR
390, our records will be constantly available, in humanlanguag(~ Conn, to satisfy this second requirement. And,
since these same records will store data in the electronic-

language of the computer, they will be constantly available
for high speed processing.

"THREE ... The NCR 390 will up-grade our reporting
abilities. It will contribute greatly to the needs we have for
more timely factual data at every level of management,
which is so essential in a highly competitive market.
"With these many abilities, we are sure our choice of the
NCR 390 Computer was a highly-profitable decision."

Ne\tV Hypertape Drive gives your IBM

This new Hypertape stores two to four times as much information and delivers the information to your computer two to four times faster than your present tape system.
The magnetic tape is kept in a sealed, dust-proof cartridge. All you do is place the cartridge
in the tape drive ... the rest is automatic. No more manual threading and unthrea.ding. It
takes only 20 seconds or about one-quarter the time it takes with conventional reels.

Although the reputation of the Bendix G-15 computer for reliability is well known, we thought Computers and Automation might be interested in the
most recent ·statistic-this we believe is a record that
has not yet been equaled:
The Bendix G-15 com pu tel', machine
No. 334, installed -at Eastman Kodak Co.,
Rochester, N. Y., has had an uptime of
100 per cent, for more than a year. The
computer is used approximately 50
hours a week.
.
-Incidentally, the average uptime figure for all G-15
customer installations is, according to present records,
over 97 per cent. We understand that this record also
has not yet been equaled. I t is worth remarking that
the G-15 is an el~ctronic tube computer.

CONFERENCE ON SELF-ORGANIZING
SYSTEMS-l\fAY, 1962
Marshall C. Y ovits
Conference Chairman Office of- Naval H(~~earch
Washington 25, D. C.

A conference on Self-Organizing Systems will be
held on May 22, 23, 24, 19G2, co-sponsored by the
Information Systems Branch, Office of Naval Research
and the Armour Research Foundation. This Conference will be held at the -Museum of Science and
I ndustry, Chicago, Illinois.
The ohjective of this Conference is to bring together
research workers who are concerned with the evoluIiOIl of self-organizing information systems. While improved ullderstanding and modeling of cognitive,_
Iearllillg. and growth processes is clearly of interest,
Ihis COllference is primarily concerned with these
fields ollly insofar as they interact with the major
ohjecl ive. In the three years intervening since the
previous ONR-ARF Conference on this topic there
has been greatly increased emphasis placed on SelfOrganizing Systems. It appears to be an appropriate

T be use of programed instruction in schools,
business, industry, and the arm,ed forces is one of
tbe most exciting and prom,ising innovations
ever made in the field of education a11d training.
N ow, this new book brings together the 11M1ty
and complex hows and whys:

PROGRAMED
INSTRUCTION
USES IN INDUSTRY
AND ARMED FORCES
Edited by STUART MARGULIES,
Research Psychologist, and
LEWIS D. EIGEN, Executive Vice President,
Center for Programed Instruction, I11c.
Forty leading figures in the field of programed
instruction have combined their experience, and their
research findings, to present vital information on
applications and implementation of this important
new technique. Most of the material has been prepared especially for this book, and it gives intensive
coverage of all areas of application (present and projected), estimates of economic feasibility, data on
uses of programed instruction, and reactions of
students to the material. In short, virtually everything that is known about the subject is covered here.
Drawing upon a wealth of empirical data, the
authors make a penetrating analysis of the role of
machines in training and education. Equally important, they explore the many practical questions
involved in applying programed instruction:
• How much time and money must be spent in
preparing training programs using machines?
Q Should you use teaching machines or programed
books?
• What sort of situations are appropriate for using
programed instruction?
• How much training time will programed instruction
require, as against programs using conventional
methods?
, These and a good many other questions are set
against such a background that you will be able to
answer them precisely and correctly. In effect, you
will have a sound basis for making necessary policy
decisions with regard to the application of programed instruction to specific training and educational situations.

Fo1Jowing a brief discussion of the nature of assembly programs, this publication
describes IS0PAR. The program's input
formats, pseudo-ops, outputs, processing
techniques and space requirements are
given. Many examples of its application
arc demonstrated. An analysis of the desirability of the program's unique features
concludes the discussion.
