LON-CAPA is a web-based interface that helps to organize and present your
course website, deliver and manage problem problems, and manage student
enrollment.
All author functions are done using a web browser (Netscape 4.x or higher
is recommended) and the LON-CAPA Author Interface.
The URL for LON-CAPA is

Author Remote Control
\layout Comment
Comment on the remote controls: I'll only mention this once, but imagine
this comment exists everywhere a remote control image is used.
The whole
\begin_inset Quotes eld

remote control
\begin_inset Quotes erd
\end_inset
metaphor is fundamentally flawed and probably can't be salvaged.
Why is it flawed?
\layout Comment

\layout Comment
1.
The remote control invokes a metaphor, that of remote controls.
However, remote controls are useful in the real world, despite the overwhelming
complexity of modern remotes, for three major reasons: One, they never,
ever, ever change.
Two, they provide immense amounts of tactile feedback, allowing one to
overcome the complexity of using one by putting the knowlege into motor
memory.
(There are equivalent usability principles in usability, as well; look
up Fitt's Law, for instance.) Three, they all basically do the same thing;
pick up an unfamiliar TV control and you at least know in advance there
will be numbers for channel changing, vol up and down, chan up and down,
mute, etc.
The remotes used in this system do not have any of these properties.
Remotes are actually horrid UI, because they are very, very difficult to
learn; they make up for it by being useful and persistent.
\layout Comment
Further, remotes should *do* things.
This remote is like a remote that no matter what button you push, it invokes
a menu.
Most remotes have
\series bold
one
\series default
explicit
\begin_inset Quotes eld
\end_inset
menu
\begin_inset Quotes erd
\end_inset
button to invoke a menu that has all the feature that aren't worth valuable
remote control space.
\layout Comment
In fact, the metaphor is so unsuccessful that any moderately savvy internet
user will almost immediately come to conceptualize the remote as just another
list of links, albiet a clumsy and inconvenient one.
Why not give them that in the first place?

I see in the tutorial has eight buttons, which nearly immediately becomes
seventeen (!) buttons, all incomprehensible, and I didn't get a chance
to count during the interview, but I saw a remote flash by (student remote?
admin remote? that wouldn't matter as much) that had at least twenty, probably
24 buttons, again, all or nearly all incomprehensible.
This is needlessly intimidating.

By commiting to this
\begin_inset Quotes eld
\end_inset
remote control
\begin_inset Quotes erd
\end_inset
layout, you commit to a remote control's layout limitations, except that
an actual remote control can get away with a 6pt or smaller font, or wierd
specialized symbols, or whatnot.
I'm looking at a (real) remote control right now that manages to get
\begin_inset Quotes eld
\end_inset
channel return
\begin_inset Quotes erd
\end_inset
onto one button.
That whole phrase fits *twice* into the space the

no sane remote control designer could deal with.

Requiring the user to mouse over something to see what it does is not a
solution.
Limiting yourself to an 8 by 2 array of characters to explain yourself
compounds the problem even more.
(Another over-literal extension of the remote control metaphor.) Also, as
you may have observed, the accessibility of this is nil.
\layout Comment

The upshot is that the only upside to the remote control is a moderately
pleasing graphic; the downsides are pretty much everything, up to and including
possible illegality under accessability laws.
Unfortunately, I do not see any way to salvage any aspect of the remote
control; it's going to suck until it's replaced.
Pleasing graphics are relatively easy to come by nowadays; it should not
drive the design.
I'll admit (freely!) I'm not a graphics designer...
graphics designers aren't web developers (designers), either.

We're data-mining the web logs to see what people actually use.
This is good.
We may need to do some really simple stuff before he finishes.
Raw statistics on what buttons are pressed most often can probably be interpret
ed easily enough for our purposes.
No matter what the final design is, it should emphasize the two or three
commands used day in and day out, as determined by empirical analysis,
and shuffle the other commands onto another sub menu or sub menus.
Then, use the additional space you'll have (even if you keep the same size
window) and actually *spell out* the options.

Creating Online Problems Using LON-CAPA
\layout Standard
If you're following this as a tutorial, go ahead and make one of each of
these problem types now.
We'll be using them later as raw material to assemble maps and sequences.
\layout Subsubsection
Problems Types
\layout Standard
There are five types of problems that can be created with the LON-CAPA system:
Radio Response, Option Response, String Response, Numerical Response, and
Formula Response.
You will need to identify which types of problem you want to use and create
appropriate questions for your course.
\layout Subsubsection
Foils
\layout Standard
In the LON-CAPA system, a
\series bold
Foil
\begin_inset LatexCommand \index{Foil}
\end_inset
\series default
is a choice in a Radio Response or Option Response problem.
For instance, True/False problems have two foils, one for True, and one
for False.
Foils do not need to be text; they can be images or other resources.
\layout Subsubsection
Radio Response
\begin_inset LatexCommand \index{Radio Response}
\end_inset
Problems
\layout Standard
\series bold
Radio Response
\series default
problems represent multiple choice questions.
A True/False problem is a special case of Radio Response problem with two
foils, True or False.
\layout Standard
Multiple choice problems contain between 3 and 10 foils.
You may display from three to five foils for each problem and the system
randomly picks the choices that are presented to the student.
\layout Comment
Eh? If this means what I think it means, clarify.
Is the system really incapable of showing eight choices all at once?
\layout Subsubsection
Option Response
\begin_inset LatexCommand \index{Option Response}
\end_inset
Problems
\layout Standard
Option Response problems present foils to the student with drop-down boxes.
A group of foils is created for each concept group, and the system will
pick one to present to the student from each group.
The student must match each of his or her questions correctly to the possible
answers before receiving credit for the problem.
For more details, see the Create Option Response (
\begin_inset LatexCommand \ref{Create Option Response Problem}
\end_inset
).
\layout Subsubsection
String Response Problems
\layout Standard
\series bold
\begin_inset LatexCommand \index{String Response}
\end_inset
String Response
\series default
problems are problems in which the student submits a string of characters
for the answer.
Examples of string response questions are vocabulary tests, short answer
and entering chemical formulas.
\layout Standard
Note that it is easy to abuse String Response problems.
For instance, consider the question
\begin_inset Quotes eld
\end_inset
Who wrote 'Huckleberry Finn'?
\begin_inset Quotes erd
\end_inset
If you tell the system the answer is
\begin_inset Quotes eld
\end_inset
Mark Twain
\begin_inset Quotes erd
\end_inset
, and a student answers
\begin_inset Quotes eld
\end_inset
Twain
\begin_inset Quotes erd
\end_inset
, the system will mark it wrong.
If they answer
\begin_inset Quotes eld
\end_inset
Samuel Clements
\begin_inset Quotes erd
\end_inset
, then the student will definately get it wrong.
There is some room for flexibility in the string processing, but it can
be difficult to get it all right.
Before you use a String Response problem, be sure you can easily characterize
correct answers.
\layout Subsubsection
Numerical Response Problems
\layout Standard
\series bold
Numerical Response
\begin_inset LatexCommand \index{Numerical Response}
\end_inset
\series default
problems are answered by entering a number and (optionally) a unit, such
as 2.5 m/s^2.
Tolerance and significant digits can be specified as well.
\layout Subsubsection
Formula Response Problems
\layout Standard
Formula Response problems are questions in which the student types in a
math formula for the answer.
If the answer is

\layout Standard
Each
\series bold
Concept Group
\series default
has some number of foils representing questions which are conceptually
related.
Option Response Problems can have between 4 and 8 Concept Groups in a problem.
When the Option Response problem is presented to a student, the LON-CAPA
system will randomly select one foil from each Concept Group and present
it to the student.
In order to receive credit for the problem, the student must answer all
of the Concept Group foils correctly.
\layout Subsubsection
Example: Concept Group
\layout Standard
For example, a Concept Group may contain the following True/False questions:
\layout Itemize
\begin_inset Quotes eld

Mark Twain wrote
\begin_inset Quotes eld
\end_inset
Huckleberry Finn
\begin_inset Quotes erd
\end_inset
.
\layout Itemize
Mark Twain spent most of his life in the Congo.
\layout Standard
For each foil, the author marks it True or False.
When the student logs on and attempts to answer this question, the student
will see only one of the four choices for that concept group.
They then go on to do the remaining three to seven Concept Groups in this
question before submitting their answer.
\layout Subsubsection
Example: Matching Problem
\layout Standard
You might want to ask the student to match musical compositions with their
composers.
You could create an Option Response problem with 4 Concept Groups, and
place the following four things each in their own concept group:

Formula Response problems are answered by entering a mathematical formula.
For instance, a numerical response problem might have an answer of
\begin_inset Formula \( x^{2}+11 \)

The answer may be in any equivalent format.
For instance, for

Publishing Your Resources
\layout Standard
In order to make the content you've created available for courses to use,
you must publish your content.
LON-CAPA provides an easy interface for publishing your content pages,
problem resources, and sequences.
A common interface allows you to specify title, author information, keywords,
and other metadata.
LON-CAPA uses this metadata for many things, and it's importent to fill
the metadata out as accurately as possible.

\begin_inset LatexCommand \label{What Is Metadata?}

\layout Standard
\emph on
Metadata
\emph default
is
\emph on
data about data
\emph default
.
Metadata can often be thought of as a label on some bit of information
that can be useful to people or computer programs trying to use the data.
Without metadata, the person or computer trying to use the original information
would have to just guess what the original data is about.
For instance, if you create a problem and neglect to say in the title or
subject of the problem what it is about, then a human who wants to use
that problem would have to read the problem itself to see what it was about,
which is much more difficult then just reading a title.
A computer trying to do the same thing would just be out of luck; it is
too stupid to understand the problem statement at all.
\layout Standard
One example of metadata you use all the time is the <TITLE> of a webpage,
which usually shows up in the title bar of the browser.
That's information about the webpage itself, not actually part of the web
page.
People use it when they bookmark a page, so they know what the page is.
Search engines use it as a clue about the content of the web page.

The language is the language the problem is written in.
The Publisher/Owner is the person who owns the problem; it should be the

In larger environments, it may be a coordinator or manager.
\layout Standard
The

Additional keywords
\series default
allows you to add any keyword to your problem that are not actually in

For instance, on that same problem a physicist might add the keyword
\begin_inset Quotes eld

Example of the Map Editor
\begin_inset LatexCommand \label{Map Editor Example Figure}
\end_inset
\end_float
Maps are very powerful and can do a lot.
They can make decisions as the user progresses, and go down different paths
under different circumstances.
For instance, a map can go down one path if the user gets a problem right,
and another path if they don't.
\layout Standard
To facilitate editing these powerful entities, LON-CAPA has a map editor
that helps you take advantage of this power, as seen in figure
\begin_inset LatexCommand \ref{Map Editor Example Figure}
\end_inset
.
The map editor can display the different paths in your browser, and allow
you to edit, insert, and delete resources from your map.
The editor has a
\series bold
Start
\series default
area and a
\series bold
Finish
\series default
area.
The students in the course will progress along on path or another, depending
on decisions made at each resource, as explained later.
Different paths are represented with different lines in the map editor.
In the example figure, there are two paths the student can go down, depending
on whether or not they get the problem at the branch point correct.
By the end of this section, we'll create the map represented in this figure.
\layout Standard
The branching ability can obviously be used to help the student understand
the concept in the problem by having them go through some extra material
based on their performance, but the total uses of this feature are limited
only by your imagination.

Numerical Response problems are very powerful.
In fact, they are so powerful it would be impossible to fully explain what
is possible in a document like this.
This chapter will focus on just getting you started with Numerical Response
problems, and showing you some of the possibilities, with no prerequisite
knowlege necessary.
The more you learn, the more you will find you can do.

In this chapter and the next, I will use the terms
\series bold
static
\series default

\series bold
Static
\series default
means the object never changes, and is the same for each student.
By contrast,
\series bold
dynamic
\series default
means the value can change, because there is some script that computes
it for each student.

\begin_inset LatexCommand \ref{Numerical Response Editor Figure}
\end_inset
:
\layout Enumerate
The
\series bold
Script
\series default
.
The script is the heart of advanced Numerical Response problems.
It can be used to decide some of the parameters of the problem, compute
the answer to the problem, and do just about anything else you can imagine.
The Script language is
\series bold
Perl
\begin_float footnote
\layout Standard
For lots and lots more information about Perl, see the Perl website at http://ww
w.perl.org/ .
\end_float
.
You do not need to know Perl to use the Script block, as we will be stepping
through some advanced examples in this chapter, but knowing Perl can help.
\layout Enumerate
Like other problem types, the
\series bold
Text Block
\series default
is used to display the problem the student will see.
In addition, you can place things in the
\series bold
Text Block
\series default
based on computations done in the
\series bold
Script
\series default
.
\layout Enumerate
The
\series bold
Answer
\series default
is the answer the system is looking for.
This can also use parameters from the
\series bold
Script
\series default
block, allowing the answer to be computed dynamically.
\layout Enumerate
A
\series bold
tolerance
\begin_inset LatexCommand \index{tolerance}
\end_inset
\series default
parameter, which determines how closely the system will require the student
answer to be in order to count it correct.
For technical reasons, it is almost never a good idea to set this parameter
to zero
\begin_float footnote
\layout Standard
Computers can only approximate computations involving real numbers.
For instance, a computer's [decimal] answer to the simple problem
\begin_inset Formula \( \frac{1}{3} \)
\end_inset
is
\begin_inset Quotes eld
\end_inset
0.33333333333333331
\begin_inset Quotes erd
\end_inset
.
It
\emph on
should
\emph default
be an infinite series of 3's, and there certainly shouldn't be a
\begin_inset Quotes eld
\end_inset
1
\begin_inset Quotes erd
\end_inset
in the answer, but no computer can represent an infinitely long, infinitely
detailed real number.
Therefore, for any problem where the answer is not a small integer, you
\emph on
need
\emph default
to allow a tolerance factor, or the students will find it nearly impossible
to exactly match the computers idea of the answer.
\end_float
, though you may find the default too large for some problems.
There are two kinds of tolerance.
If there is some answer
\begin_inset Formula \( a \)
\end_inset
and a tolerance
\begin_inset Formula \( t \)
\end_inset
,
\begin_deeper
\layout Enumerate
an
\series bold
Absolute
\series default
tolerance
\begin_inset LatexCommand \index{absolute tolerance}
\end_inset
\begin_inset LatexCommand \index{tolerance, absolute}
\end_inset
will take anything in the range
\begin_inset Formula \( a\pm t \)
\end_inset
.
So if
\begin_inset Formula \( a=10 \)
\end_inset
and
\begin_inset Formula \( t=2 \)
\end_inset
, then anything between 8 and 12 is acceptable
\begin_float footnote
\end_deeper
\layout Standard
For much the same reasons a tolerance is almost always a good idea, it's
almost impossible to say whether an answer that is
\emph on
exactly
\emph default
\begin_inset Formula \( a\pm t \)
\end_inset
will be accepted by the computer.
But the computer does use many decimal places of accuracy; if you want
to have the student answer exactly
\begin_inset Quotes eld
\end_inset
2
\begin_inset Quotes erd
\end_inset
, then specifying a tolerance of
\begin_inset Quotes eld
\end_inset
.0000001
\begin_inset Quotes erd
\end_inset
is OK.
(Don't use too many more zeros, though you can use less if you like.)
\end_float
.
Any number in the tolerance field
\emph on
without
\emph default
a
\series bold
%
\series default
symbol is an absolute tolerance.
\begin_deeper
\layout Enumerate
a
\series bold
Relative
\series default
tolerance
\begin_inset LatexCommand \index{relative tolerance}
\end_inset
\begin_inset LatexCommand \index{tolerance, relative}
\end_inset
will take anything in the range
\begin_inset Formula \( a\pm at \)
\end_inset
, where
\emph on
t
\emph default
is interpreted as a percentage.
Any number in the tolerance field
\emph on
with
\emph default
a
\series bold
%
\series default
symbol is a relative tolerance.
For example,
\begin_inset Formula \( a=10 \)
\end_inset
and
\begin_inset Formula \( t=10\% \)
\end_inset
will accept anything between 9 and 11.
\end_deeper
\layout Enumerate
A
\series bold
significant figures
\series default
specification tells the system how many significant figures there are in
the problem, as either a single number or a range of acceptable values,
expressed as
\series bold
min,max
\series default
.
The system will check to make sure that the student's answer contains this
many significant digits, useful in many scientific calculations.
For example, if the problem has three significant digits, the significant
digit specification is
\begin_inset Quotes eld
\end_inset
3
\begin_inset Quotes erd
\end_inset
, and the answer is
\begin_inset Quotes eld
\end_inset
1.3
\begin_inset Quotes erd
\end_inset
, the system will require the students to type
\begin_inset Quotes eld
\end_inset
1.30
\begin_inset Quotes erd
\end_inset
, even though numerically,
\begin_inset Quotes eld

1.3
\begin_inset Quotes erd

\layout Subsection
Simple Script Usage
\layout Standard
Totally static problems only scratch the surface of the Numerical Response
capabilities.
To really explore the power of LON-CAPA, we need to start creating dynamic
problems.
But before we can get to truly dynamic problems, we need to learn how to
work with the
\series bold
Script
\begin_inset LatexCommand \index{Script}
\end_inset
\series default
window.
\layout Standard
A script consists of several
\series bold
statements
\series default
, seperated by
\series bold
semi-colons
\series default
.
A
\series bold
statement
\begin_inset LatexCommand \index{statement}
\end_inset
\series default
is the smallest kind of instruction to the computer you can give.
Most problems will be built from several statements.
\layout Standard
A script can contain
\series bold
comments
\series default
, which are not interpreted as statements by the computer.
Comments start with
\series bold
#
\series default
, and go to the end of that line.
Thus, if a line starts with #, the whole line is ignored.
Comments can also begin in the middle of a line.
It is a good idea to comment more complicated scripts, as it can be very
difficult to read a large script and figure out what it does.
It is a
\emph on
very
\emph default
good idea to adopt some sort of commenting standard, especially if you
are working in a group or others may use your problems in the future.
\layout Standard
One of the simplest statements in LON-CAPA is a
\series bold
variable assignment
\series default
.
A
\series bold
variable
\series default
can hold any value in it.
Simple values, such as a number or a string of text, start with a
\series bold
$
\series default
.
In the
\series bold
Script
\series default
, you need to assign to variables before you use them.
Put the program in Figure
\begin_float fig
\layout LyX-Code
\align center
$variable = 3;
\layout Caption
\pextra_type 3 \pextra_widthp 40
A simple script with a variable
\begin_inset LatexCommand \label{A simple script with a variable}
\end_inset
\end_float
\begin_inset LatexCommand \ref{A simple script with a variable}
\end_inset
into the
\series bold
Script
\series default
field of the Numerical Response.
This creates a simple variable named
\series bold
variable
\series default
and assigns it the value of
\begin_inset Quotes eld
\end_inset
3
\begin_inset Quotes erd
\end_inset
.
That's one statement.
\layout Standard
Variable names are
\emph on
case sensitive
\emph default
, must start with a letter, and can only consist of letters, numbers, and
underscores.
Variable names can be as long as you want.
\layout Standard
Getting variable names right is a skill.
Variable names should not be too long, because they become easy to mistype.
Variable names should also not be too short, with the exception of some
conventionally short variable names we'll talk about later.
\layout Standard
There are many variable naming conventions, covering both how to name and
how to capatalize variables
\begin_float footnote
\layout Standard
The author favors
\family typewriter
capsOnNewWords
\family default
.
Some people use
\family typewriter
underscore_to_seperate_words
\family default
.
Many use uppercase letters to specify constants like
\family typewriter
PI
\family default
or
\family typewriter
GOLDEN_MEAN
\family default
.
Some people always
\family typewriter
StartWithCapatalization
\family default
.
What's really importent is to be consistent, so you don't have to guess
whether the variable you're thinking of is
\family typewriter
coefFriction
\family default
,
\family typewriter
CoefFriction
\family default
,
\family typewriter
COEF_FRICTION
\family default
, or something else.
\end_float
.
It is a good idea to adopt a standard.
If you are working with a group, you may wish to discuss it in your group
and agree on a convention.
\layout Standard
If you
\series bold
Submit Changes
\series default
and
\series bold
View
\series default
the problem, you'll see nothing has changed.
That's because in order for a variable to be useful, it must be used.
The variable can be used in several places.
\layout Subsubsection
Variables in Scripts
\layout Standard
Variables can be used later in the same script.
For instance, we can add another line below the
\family typewriter
$variable
\family default
line as such:
\layout LyX-Code
$variable2 = $variable + 2;
\layout Standard
Now there's a variable called
\family typewriter
$variable2
\family default
with the value
\begin_inset Quotes eld
\end_inset
5
\begin_inset Quotes erd
\end_inset
.
\layout Standard
Variables can also be used in
\emph on
strings
\emph default
\begin_inset LatexCommand \index{strings}
\end_inset
, which are a sequence of letters.
The underlying language of the script, Perl, has a very large number of
ways of using variables in strings, but the easiest and most common way
is to use normal double-quotes and just spell out the name of the variable
you want to use in the string, like this:
\layout LyX-Code
$stringVar =
\begin_inset Quotes eld
\end_inset
I have a variable with the value $variable.
\begin_inset Quotes erd
\end_inset
\layout Standard
This will put the string
\begin_inset Quotes eld
\end_inset
I have a variable with the value 3.
\begin_inset Quotes erd
\end_inset
into the variable named
\begin_inset Quotes eld
\end_inset
stringVar
\begin_inset Quotes erd
\end_inset
.
\layout Standard
If you are following this chapter as a tutorial, add the previous two lines
and save the problem.
There's no need to view it; there's still no visible change.
\layout Subsubsection
Variables in the Text Block
\layout Standard
Once you've defined variables in the

you can place the following in the

\series default
