Summary: Facilities for tutorial groups

Initial Comment:
It should be possible to record in the register which 

students are assigned to which tutorial groups.  Email 

queries from students should be directed to their tutors.  

The entry page should remind students which group they 

are in, and where and when it meets.  There should be 

facilities to handle requests for a change in tutorial 

groups.

Summary: Totals in subject results page

Initial Comment:
I have two quizzes, with weights 0 and 1 respectively.  

If a student has done both quizzes then the subject 

results page reports the mark for the second quiz as the 

total, which is correct.  However, if the student has only 

attempted the first quiz, then the results page gives the 

mark for the first quiz as the total, instead of giving zero 

as it should do.

Summary: Links from question review page

Initial Comment:
There are links on the quiz review page allowing you

to review the whole sequence of answers that a 

student gave to a particular question.  These seem

to work OK, but the corresponding links on the 

resulting question review page do not.  They send

you to the wrong attempt, or mess things up in other

ways.  Often you see a message saying "However, you 

previously made a correct attempt, so the mark for the 

last attempt is disregarded" in cases where this is not 

appropriate.

Initial Comment:
The servlet monitor reports when each process was

last used.  This information seems inconsistent with

that contained in the "Recent Requests" table.  It 

looks like the "Last Used" field gets set to the last

time at which the monitor was refreshed, or something

like that.

I think that `aim/TestNumeric` should set Digits for itself so 

as to produce the expected behaviour.  It will probably need

to declare its arguments as 'uneval' and only evaluate them

after setting Digits.  But there might be some pitfalls with

this that I haven't thought of.

I just noticed the subject line of your message after I replied to it, and
I'm starting to think that the question I answered in the previous message
might not be what you were asking at all.  Duh. Sorry about that.  Perhaps
you are asking how to give students the feedback on a question like:

------------------
What is 7-5*3/2^2?
------------------

when they use the wrong rules of precedence of operators to get an answer
like, say,

((7-4)*3/2)^2=9

?  If that is what you were asking, then no, I don't know of any such
implemented built in checking routine.  You could manually check for the
common things in you s> procedure of course. But I agree that it would be
nice to have an authoring utility that checks for such all such things
automatically.  Along these lines it would be nice to have a utility that
checks an answer for sign errors, like if the student answer is a sum that
differs from the teacher's answer only by one or more negative signs in some
subexpressions.  Perhaps this is evidence that in addition to
SyntaxHints.mpl, which checks the student's answer for common syntax errors,
we also should have a new authoring package called CommonErrors.mpl that
checks the students answer for common mathematical errors?  Then you could
invoke the appropriate error checkers in the s> proc.

You are correct in assuming that it is possible to save Scientific Workplace
files as a generic LaTeX file that anyone can compile and that preserves the
LaTeX formatting of the documents. Indeed, that is how I produced the first
version of AuthoringTtH.tex -- I saved the SWP file as a plain LaTeX
document and then edited it by hand to cure the things that TtH objected to
(and to make it a little easier for people to edit it by hand).

Unfortunately the pdf draft version of the guide that I had posted
originally was not created by compiling the SWP document with a LaTeX
compiler. The WYSIWYG interface of Scientific Workplace is a front end for
LaTeX, and the files are stored in LaTeX format, but the on-screen editor
displays them in a nice GUI window that you can print directly to a printer
without compiling through LaTeX first. Thus it is a WYSIWYG editor only if
you print directly to a printer from the GUI interface, not if you compile
the document with LaTeX (if you compile it then it is only a "What You See
Is Pretty Close to What You Get" editor).

So the original pdf version was created by printing from the Scientific
Workplace GUI directly to a pdf printer driver without running it through a
LaTeX compiler, i.e. that is the way the document looks in the SWP editor on
the screen, not how it looks when you compile it.  If I do run that file
through the LaTeX compiler I get a version that looks similar to the version
you get by running AuthoringTtH.tex through pdftex... all text in black, no
background colors, and things spilling into the margins.

So the bottom line is that the original pdf version I had originally posted
can only be produced using Scientific Workplace.  Since I gather that not
all of the developers use nor want to use SWP, I converted it to a
hand-editable LaTeX and ran that through TtH to get the html version.  The
advantages to this are that (a) the rest of the docs are in html, so it is
consistent (b) since it is formatted with TtH the example questions look
just like they look in an actual AiM question) and (c) the .tex version is
hand-editable by everyone so people can add to it and modify it without
having Scientific Workplace.  The version of the document that you get by
compiling AuthoringTtH.tex is not all that bad (if you uncomment some of the
lines I have at the top of the file before compiling), and could be improved
a lot by tweaking the TeX some more if we want to produce a pdf version
eventually.  There is also probably some way to get the colors for the fonts
and background colors back to match the SWP style, but I'm a little rusty on
my LaTeX (too much SWP :)) and don't know offhand how to do that.

OK, so that is a longwinded way of saying that while I'm more than willing
to post the SWP version, only people who have SWP will be able to edit it
and produce the pdf version of it that looks like the original.  I think the
better thing to do would be to improve the formatting of the pdftex version
of the existing AuthoringTtH.tex file until it can be used to make a
presentable pdf version.

Let's see... AiM currently tells them that they are missing a *:

-------------------------------------
There is a syntax error in your answer. You may need to insert stars in some
or all of the indicated places
7 - 5*X3/2^2
-------------------------------------

i.e. it is assuming that X3 is a variable and the student forgot the * in
trying to multiply 5 times X3.  In your situation it seems that the student
is trying to use X where he meant to use *.

I don't think we want to simply prevent students from using X as a variable
in their answer, since (in addition to questions that use X in the question
and/or teacher's answer) a student might correctly use that as a constant of
integration (maybe they are feeling creative :)) or as the indexing variable
of a summation, etc. even if it doesn't appear in either the question or the
teacher's answer.

Perhaps the best thing to do would be to allow the student to use X in their
answers, but whenever their answer fails validation for some other reason,
check to see if it has an X in it and also if replacing X with * produces a
Maple expression that is syntactically correct and matches the type
specification for the answer. Then we could print a validation message that
says (in addition to the existing validation message):

"Remember that the multiplication symbol in AiM is *, not X. Never use X as
a multiplication symbol."

If you want to try to implement this I think you probably need to add a
routine to check for this in aim/SyntaxHints.mpl and put the appropriate
hook in aim/TextQuestion/BasicValidation() routine in aim/TextQuestion.mpl.
You might also want to check to see if MatrixQuestion needs a similar hook.

[Aimmath-developers] rules of precedence

Hi there...

   has anyone implemented a functionalitty in AIM (or MAPLE for that 
matter) that could predict what went wrong when a student was evaluating 
an expression like 7 - 5X3/2^2 i.e. to feedback to students what rule 
they didn't follow ? Or is there something similar that I could extend ?

thank you very much for your help with my multi-part question problem. Your

It is still not quite clear to me when exactly the answer value is

[Aimmath-developers] Authoring Guide goes high tex

[Ken M. <mo...@pt...>]

Hello all,

I finally completed the sections of the Authoring Guide about the authoring
packages/utilities I wrote (i.e. Inert, Random, SET, Number, Decimal, and
Keys()).  I deleted the .pdf file from CVS and uploaded two new files...
AuthoringTtH.html and AuthoringTtH.tex.  The former file was produced by
running the latter file through tth with the command:

tth -L AuthoringTtH

Thus if anyone would like to contribute sections on the other authoring
packages (Test, Int, Diff, Matrix, Trig, and Calc) please do not edit the
html directly, but rather make all of your changes to the tex file and then
run it through tth to produce the html.  Note also that you have to compile
the tex file with an ordinary LaTeX compiler in order to produce the Table
of Contents file (authoringtth.toc), before running it through TtH so TtH
can produce the nice linked table of contents automatically.

The AuthoringTtH.tex file does compile correctly if you run it through an
ordinary LaTeX compiler, but the dvi that is produces still has some awkward
formatting since I was trying to make it look nice in html, not in dvi.
Still, it is possible to produce a readable dvi file from the tex file if
you uncomment some of the lines at the top of the tex file.  For end users
who want to print the entire guide, I'm not sure if they would get better
results printing the html version or a dvi version.

On the Things to Do list:

* It would be nice to have sections on the other authoring packages.

* It would be nice to combine the question syntax help file (format.html)
with the AuthoringTtH.tex file at some point to make a single Users Guide
that would format nicely in both html and dvi/pdf. Unfortunately that would
mean creating a .tex version of format.html.

* It would be nice to tweak the current .tex file so that it produces a nice
dvi file in addition to the nice html file so we could post a pdf version of
the dvi version of the tex version of the current version of the Authoring
Guide.

Please report any typos or errors, or better yet, just fix them. :)

ciao,
KEN

The template in aim/try/Quiz.mpl currently starts with

Even after the student answers, ans doesn't get assigned at the right time
to be usable in the 2nd part, which means that you are forced to use s>
and to give a dummy teacher answer, e.g. (I also change ans to ans1 
below ... and note that ans1 is in fact of type listlist, *not* matrix
... this choice would have been made so that AIM could display student/
teacher answers in a linear fashion)

sq>

Note that ans1 *is* available inside the solution.

Before the student answers the first part of the question, the value of the
variable, ans, is just 'ans', so the det(ans) call at your a> prompt is
giving the error.

parameters are correctly set. However if an external program wants to make a
change in the Quiz options it would like to be able to call admin/Quiz
without knowing the order of all the questions. Thus in order to make it
easier for external programs to interface with AiM I would like to add an
extra optional argument to admin/Quiz called "KeepQuestionOrder" which
avoids the reordering of questions.

I have committed the required change to admin/Quiz (two lines) so that you
can see what is involved. If there are any objections to the changes I will
take them out of CVS again.

Summary: Admin query of server clock

Initial Comment:


I think it would be very useful if some of the pages 

contained a small "created at xx:yy:zz, on ??th *** 

200@" at the bottom - in the past I've had problems 

with the server clock running fast and slow.  This would 

be an easy way to check the time of the server.



Perhaps this would be useful on some of the student 

pages also to let the know at most how much time they 

have left on an assessed quiz.  Again - they are being 

judged by the server's time and this may not correspond 

to their watch.  At least this will deprive any student of 

an after plea of "I didn't know what time the server was 

keeping".

[Aimmath-developers] More configuration variables

[Gustav W D. <gw...@yo...>]

I have introduced (but not committed yet) 5 more configuration variables:

 [`SourceEditBoxWidth`,
  posint,"
The width of the source edit textfield in pixel."],

 [`SourceEditBoxHeight`,
  posint,"
The height of the source edit textfield in pixel."],

 [`ImageFormat`,
  string,"
The image format used for Maple plots. Can be either gif or jpg."],

 [`ImageWidth`,
  posint,"
The width of Maple plots in pixel."],

 [`ImageHeight`,
  posint,"
The height of Maple plots in pixel."],

The SourceEditBox dimensions is because I always felt that the box is
inconveniently small. The Image options are because that makes it easier for
us to produce pdf problem sheets (gif is a proprietary format and thus not
supported by pdftex).

Am I right in assuming that having more configuration variables does not
cost much in the way of performance? Are there any objections to the
practice of introducing many new configuration variables?

In fact I thing that the more things can be configured from within
AutoConfig.mpl the better.

If it's how I think you mean, then yes I have noticed this. However, I
now have all my quiz questions as single-question files, which I store in
directory /examples/Site and each quiz file source file in a directory
of form

  root/subjects/<subject>/quizzes/<quiz>/source/

contains just lines of form:

i> EXAMPLES/Site/<question1>,
   EXAMPLES/Site/<question2>,
   ...

In this way, the questions are ordered in precisely the listed order.
I haven't been using the name> or nm> tag to rename questions; I'm
not sure if that affects the ordering.

[Aimmath-developers] reordering of questions

[Gustav W D. <gw...@yo...>]

We noticed a very annoying phenomenon: when recompiling a source file AiM
reorders the questions. One then has to go back to the Quiz administration
page and put them back in the right order. Does the same happen for you?

Summary: validation using user-defined string types

Initial Comment:
In some situations, it is desirable to have students input 

their answer in a notation that cannot be parsed as a 

valid Maple expression.  In these situations it would be 

useful to be able to specify a Maple type other 

than "string" at the c> flag in a question, but still 

prevent AiM from trying to parse the student's answer.



For example, when asking a student for an answer that 

is type RepeatingDecimal (see the Decimal package) we 

must specify the Maple type as string to prevent AiM 

from trying to parse it. What would be better is to 

specify it something like



c> string,RepeatingDecimal



which would tell AiM to not parse the student's answer 

string, but to check if that answer string matches the 

Maple type RepeatingDecimal when validating it.
