The PC-CAI Program Generator, called CREATE, is very simple to use. However,
you must have a basic understanding about how a PC-CAI tutorial is set up.
With CREATE, you can create a tutorial such as the one you are now using.
Once you have progressed, you may skip using CREATE at all, and create your
own PC-CAI program using a text editor, which is provided with PC-CAI.
.skip 3
Let's discover the basic structure of a PC-CAI tutorial.

A tutorial usually begins with a title. After a TITLE is given, there will
generally be some tutorial text, such as an explanation of what is coming up,
or a teaching session. This text may precede a "Question" session, and is
displayed for the student generally once.

That is a brief look at a typical tutorial. The CREATE program can help you
create tutorials like the one outlined above.

.col 12
WHAT IS THE CREATE PROGRAM?
.col 3
CREATE is the AUTHORING SYSTEM program of the PC-CAI Development System. It
asks the tutorial author a series of questions, and from the author's answers,
the program CREATE creates a PC-CAI program (stored in a computer file), which
can then be run.

TWO MAJOR PROGRAMS USED IN THE CREATION PROCESS
.col 3
There are two major programs used in the creation process.
1. CREATE - The authoring program
2. CAI - The "run module", which interprets the tutorial program,
and causes it to do what the author has instructed. The
CAI module also contains the editor.
There is a third important program called CAI-UTIL that contains support
routines including the IMAGE maker, used for animation and program setup.

BEGINNING THE CREATE PROGRAM
.col 3
.skip 3
To begin the CREATE tutorial, you must have the PC-CAI Development System
Diskette in Drive A (or on hard disk drive C) and the "A>" or "C>" prompt
must be on the screen. The command to begin the program is simply
C>CREATE
.col 12

.col 3
Once the CREATE program begins, you are presented with a list of tutorial
types to choose from. These types define the general "look" of a tutorial.
Later, we will learn how you can create your own custom tutorial types.
┌──────────────────────────────────────────────────────────────────────┐
│1. Test:One right answer (Exact Nocase), one chance, reply │
│2. Test:One right answer (Keyword), one chance, no replies │

│4. Define your own tutorial type. │
└──────────────────────────────────────────────────────────────────────┘
.col 12
The Most Flexible
.col 3
The most flexible tutorial type causes the CREATE program to ask the tutorial
author the maximum number of questions. You will often want to use a more
restricted tutorial type to avoid answering questions unnecessary for the
particular tutorial you may be creating.

Parts 1 and 4 occur only once, and parts 2 and 3 may occur many times.
.pau (*Please press Enter*)
.cls
.cen(*Entering Text in CREATE*)
In each of the parts of CREATE where you enter textual information, the same
procedure is used.
1. The prompt ">" will always appear at the far left side of the screen.
2. As you type information on the screen, a "word wrap" will occur when the
typing reaches the right edge of the screen, so that you need not press the
enter key as you type. Pressing the Esc key ends the entry.
3. To backup and correct an entry on the same line, use the <-- key next to
the = key.
4. To backup an entire line, enter a .B after the > prompt.
5. To end a section without saving it (abort) enter a .A after the > prompt.
6. It will often be advisable to put off correcting mistakes as you are
entering textual material, and to correct those mistakes in the Editor.

Here is a typical situation: You have typed this textual material, and then
notice that the name Washington is misspelled...
>George Washington was the first President of the United States. He is
>remembered for his brilliant role commanding the Continental Army during the
>American Revolution, and his wooden teeth.
>
What should you do to correct the misspelling?
1) Enter .B three times, and re-enter the sentence.
2) Enter .A to abort the section, and begin again.
3) Wait and correct it using the PC-CAI editor.
@READ(*Enter the number of your answer here :*)

Correct, that is the best choice. To correct minor (or major) mistakes, the
PC-CAI editor will do the fastest, easiest job.

TYPES OF ANSWER MATCHES
During the course of creating a tutorial, or in the process of defining a
tutorial, you will need to specify what KIND of match to expect the user to
give to a question. This instructs the PC-CAI program how to MATCH the answer
the user gives to the answer that you have indicated as the correct answer.

.pau (*Please press Enter*)
.cls
.col 12
THE KEYWORD MATCH
.col 3
KEYWORD matches answers by testing to see if the designated answer is
CONTAINED in the user's answer (ignoring case). For instance,
The designated answer is WASHINGTON.
The user answers George Washington.
The word WASHINGTON is contained in the answer George Washington, therefore,
it is a match.
You must be careful with the keyword match since "John Washington" and
"Washington DC" would both also match the designated answer.
.pau (*Please press Enter*)
.cls
.col 12
EXACT and EXACT NOCASE
.col 3
EXACT matches answers by testing that the answer matches letter by letter,
and case is important. In other words "BILL" would not match with "Bill".
EXACT NOCASE is the same as EXACT, except case does not matter. In the
EXACT NOCASE instance, "BILL" and "Bill" would be a match.
Exact nocase is recommended for use in a multiple choice question, where the
list of answers is by letters such as
a. Washington
b. Jefferson
etc
SOUNDEX is like EXACT NOCASE, except slight misspellings will not cause a
mismatch. For instance SMITH will match with SMYTH or SMYTHE.
.pau (*Please press Enter*)
.cls
.col 12
DECIMAL
.col 3
DECIMAL indicates that the answer is a decimal number, that is a number of
the type 10 or 10.1 or 101.345. An answer of the type 1 3/4 would NOT be a
decimal number.
.col 12
LIST
.col 3
LIST allows the designated answer to be a list of words, separated by commas,
such as wheat, barley, oats. Case is not checked. The list may be in any
order since "barley,wheat,oats will match "oats,Barley, WHEAT".
.col 12
FORCE and FORCE NOCASE
.col 3
FORCE indicates that the user will be forced to enter the designated answer.
Any character which does not match the answer will be not be printed on the
screen, and a beep will indicate that the character is not a part of the
answer. FORCE checks for case, and FORCE NOCASE ignores case.

Let's say you have created the question:
.col 12
Who was the first president of the United States:
a. Benjamin Franklin
b. Johnny Carson
c. George Washington
d. Francis Asbury
Please enter your answer:
.col 3
What kind of answer type would you designate?
a. KEYWORD
b. SOUNDEX
c. EXACT
d. EXACT NOCASE
@READ(*Please enter your answer:*)
@RIGHT(*d*) EXACT NOCASE
.play (*o2mbl16cdefgabo3c*)
That is correct since you want the answer to be exact, but case does not
matter.
@wrong
No. Remember, you want the answer to match a, b, c, or d, (or A, B, C, or D).
.pau (*Please press ENTER*)
@End

Suppose you enter the question:

a. KEYWORD
b. SOUNDEX
c. EXACT
d. EXACT NOCASE
@READ(*Please enter your answer:*)
@RIGHT(*a*) exact nocase
.play (*o2mbl16cdefgabo3c*)
Correct, since you want the word WASHINGTON to be the keyword on which to
match, and you will allow for various answers such as GEORGE WASHINGTON
and G. WASHINGTON
@WRONG (*b*) exact nocase
Could be right, but let's assume you want them to spell the answer correctly.
.pau (*Please press ENTER*)
@wrong
No, you want the word WASHINGTON to be the keyword on which to match, and you
will allow for various answers such as GEORGE WASHINGTON and G. WASHINGTON
.pau (*Please press ENTER*)
@END

.col 12
SUMMARY INFORMATION
.col 3
1. The most common match used is KEYWORD, with the next being EXACT NOCASE.
2. If you use LIST, make sure the question is worded so that the user knows
that the answer must contain a list with commas separating each item.
3. SOUNDEX checks for words that "sound" correct.
4. When you use decimal, word the question so that an answer of the type
3 3/4 is not given instead of 3.75.
5. The FORCE match is not supported in the CREATE program since it supports
the concept of RIGHT, but does not allow a wrong answer. It may be added to a
tutorial using the PC-CAI editor.

The PC-CAI system consists of several "modules". They are
CREATE ....Helps you create tutorials
CAI .......Runs tutorials and contains an editor to allow you to create or
edit tutorial files.
CAI-UTIL ..Contains support routines, including the IMAGE routine that allows
you to draw pictures for use in graphics or animation.
Please Refer to the PC-CAI manual for further information.
