Summary: year out of range error

Initial Comment:
When trying to create a new quiz I get an error "Year 
out of range (must be >= 2000): 1970". 
This is on a Windows 2000 machine.

`Date/CurrentRawDate`() is used. This calls an internal
Maple function: iolib(25)
which apparently (couldn't find any documentation) returns
the number of
seconds since 00:00:00, Jan 1, 1970 ... it agrees with the 
UNIX date +"%s"
A moment ago this function gave: 1093688092   ... for me.
Maybe you could check that your Maple responds with a
similarly sized number
when you give it:  iolib(25);

Regards,
Greg

the error

Summary: Problem with rounded teacher's answer

Initial Comment:
When viewing a question as a teacher, AiM should fill in 
the answer field with the teacher's answer given in the 
question code and mark it as correct. However it 
appears that AiM first rounds the teacher's answer to 
usually three significant figures and therefore then marks 
it as incorrect. Surprisingly this only happens sometimes.

Sorry, this was entirely my own stupidity. I had wanted to 
give the teacher's answer to 6 significant figures and 
therefore gave it as evalf(ans,6). I was then surprised that it 
was printed with less than 6 significant figures. What I had 
forgotten was that the evalf(ans,6) command does NOT 
evaluate ans and then rounds to 6 figures. Rather it first 
switches to 6 figure arithmetic and then evaluates ans. 
Depending on what calculation is required to do the 
evaluation that can of course lead to fewer significant figures.

Summary: Incorrect parsing of Maple commands in OS X AiM

Initial Comment:
If one creates a new course and quiz under an OS X AiM 
installation and uses the Tutorial for the quiz, then any 
question whose answer involves exp, ln, abs, etc appears to 
have the answer parsed in reverse. For example you get an 
error saying forbidden command sba, nl, or pxe in the 
marking. I imagine this would happen for sin, cos, sum. 
However it does not happen on the question involving 
Sum. This has been around since I started using Maple 9. 
I'm not sure what is causing it. No one else using 9 seems 
to be able to reproduce it. Nowhere else in the set up of 
AiM on OS X do I have problems. Any suggestions on what 
I should look at?

[Aimmath-developers] FASD project: Online survey launched

[<ben...@id...>]

Dear Open Source developer

I am doing a research project on "Fun and Software Development" in which I kindly invite you to participate.
You will find the online survey under http://fasd.ethz.ch/qsf/. The questionnaire consists of 53 questions and you will need about 15 minutes to complete it.

With the FASD project (Fun and Software Development) we want to define the motivational significance of fun when software developers decide to engage in Open Source projects. What is special about our research project is that a similar survey is planned with software developers in commercial firms. This procedure allows the immediate comparison between the involved individuals and the conditions of production of these two development models. Thus we hope to obtain substantial new insights to the phenomenon of Open Source Development.


With many thanks for your participation,
Benno Luthiger


PS:
The results of the survey will be published under http://www.isu.unizh.ch/fuehrung/blprojects/FASD/.
We have set up the mailing list fa...@we... for this study. Please see http://fasd.ethz.ch/qsf/mailinglist_en.html for registration to this mailing list.

[Aimmath-developers] SafeParse.mpl, aim/TextQuestion.mpl changes

[Greg G. <gr...@ma...>]

Dear AIM developers,

Several times this semester students have encountered nasty errors
during validation, and on one occasion I had to track through the
logs to find out what the student had entered, because it didn't even
make it to the question history.

This sort of problem used to arise because the result of Maple's
parse command is an unevaluated expression, and so it is quite
possible to have an expression that parses ok but is not in fact
valid Maple (because it is not possible to evaluate it), e.g.
[2,3][4,5] is such a case ... when Maple comes to evaluate it,
it runs into an indexing error.

To combat this problem I added an extra 'Status' possibility to
`aim/SafeParse`, namely "Evaluation error", and now the function
`aim/TextQuestion/BasicValidation` checks this possibility and
exits cleanly. An assignment of the parse report value was also
moved later in the function to avoid an impossible evaluation.

  Regards,
  Greg

[Aimmath-developers] AutoConf*.mpl,Date.mpl,ManualConf.dist changes

[Greg G. <gr...@ma...>]

Dear developers,

Well 4th April came around and I got burnt again ... I was under the
mistaken apprehension that the Summer Time bugs had been fixed. 
(I misread the meaning of the statement in this regard in 
ManualConfig.dist.) I suppose newDate.mpl was supposed to fix it,
but it doesn't seem to be finished.

I note that you guys in the Northern Hemisphere will be burnt at the
other end because the date give for 2004 for the finish of Summer Time
is 26th October which is a Tuesday.

It's my belief that just doing a cvs update and doing

  read "AutoConf.mpl";

in maple, in AIM's .../WEB-INF/maple directory is all that's required
to fix things.

Anyway, I made changes to:

  AutoConf.mpl, AutoConfWin.mpl, Date.mpl and ManualConf.dist

I'm not sure if there need to be compensatory changes in AutoConfWin.mws.
Perhaps someone could check that.

Anyway, the main change is the introduction of the variable
`Date/SummerTimeSpec` with which one can set the Summer Time specification
for one's locale without being defaulted to a possibly erroneous setting
for the Northern Hemisphere. 

New functions added in Date.mpl are:
  `Date/DaysSince1Jan2000`, `Date/DayOfNthSundayOfMonth`, `Date/Test`

Also, `Date/SummerTime` is now a function (rather than a table), that
returns a list consisting of two month, day pairs which are the beginning
and end dates of Summer Time for the locale, determined from
`Date/SummerTimeSpec`.

Finally, `Date/IsSummer` now takes account of whether there is no Summer
Time, or whether the locale is in the Northern or Southern Hemisphere.

To explain how it all fits together, let's consider the default
`Date/SummerTimeSpec` which is [[4, 1], [10, 5]] which specifies
that Summer Time goes from April's 1st Sunday, until October's
5th or last Sunday. Given a year, month and a Sunday ordinal,
`Date/DayOfNthSundayOfMonth` returns a list specifying the day of the 
month on which the Sunday occurs, e.g. 

  `Date/DayOfNthSundayOfMonth`(2004, 10, 5)

returns [10, 31], i.e. the 5th(= last) Sunday of October occurs on the
31st of that month. Someone might like to check that Summer Time in
the Northern Hemisphere does indeed finish on the 31st October this year.
In any case, I feel confident that it doesn't finish on 26th October.

A special case is the case we have here in Western Australia (no Summer
Time at all), and this is specified by setting `Date/SummerTimeSpec`
to [[0, 0], [0, 0]]. 

The possible values of `Date/SummerTimeSpec` that I know of (including
various parts of Australia) are all listed in ManualConfig.dist.
I'm quite probably the only Southern Hemisphere user currently, but
conceivably this may change.

  Regards,
  Greg

Unfortunately almost all trigonometric and inverse 
trigonometric functions are typeset in italic as well, try arcsec 
for example. 
I think we should rely as much as possible on Maple's own 
conversion to Latex, otherwise we are always going to run 
into problems like this.

I restored the code for `latex/latex/symbol` that was 
recently removed from aim/LaTeX.mpl, and that fixed this 
problem.  If that causes formatting problems for anyone else,

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.

The servlet monitor reports when each process was

This is not a bug, it is a feature.  The recommendation 
(explained, without sufficient prominence, in the question 
syntax documentation) is that all initialisation should be 
performed in the main question body, before the first sq> 
tag.  If you want different random numbers in parts 1 and 2, 
you should do something like

h> a := rand(1..9)();
    b := rand(1..9)();

before the first sq>, and then use a in part 1 and b in part 2.

In my questions I've just put the locals at the outermost level. I can't
recall if it was expressly forbidden to have locals for subquestions.

Other flags certainly work ... in fact the forbid> flag isn't allowed
at the outer level.

subquestions haven't been around long in aim-tth ... I thought allowing
end> to finish a subquestion was somehow an inherited idea from aim-plain.
I for one have always used the esq> tag to finish a subquestion.
 
Anyway, attached is a simple differentiation of composite functions
question. (The _{\Large\circ} is an awful kludge to get the browser to
format the o in `f o g' which works for IE but sadly not for Mozilla
... probably Mozilla sets the circ symbol correctly and IE has got it
wrong).

Happy New Year ... hope it helps.

[Aimmath-developers] subquestions

[Manolis M. <M.M...@ed...>]

Hi there,

   happy new year to you all !!

    First of all, Gustav, I think the website is down again.
 
    Secondly I have some questions to ask and request some examples or 
more documentation to clarify things more. As I think I mentioned before 
we are witting a converter from questions written in AIM to an XML 
format that is then translated to the WALLIS format --- this will 
(eventually) help (simple) questions from AIM to be used in other 
systems as well. I am bit confused with subquestions (mainly because I 
've never written any in AIM) so I would appreciate if I can have some 
examples on how people use them and an answer to the following questions
   
1) The documentation says that local shouldn't be used in subquestion. 
What is the reason for this and do people follow this recommendation ?

2) What "flags" are there allowed in subquestions ? Eg. would one put 
subquestions in subquestions ?

3) What are the "historical reasons" that allow a subquestion to end 
with an "end". Are there many files around that still have that and more 
importantly I hope that people witting new files with subquestions don't 
follow this because our plan is to ignore it.

Thanks in advance for your help.

[Aimmath-developers] [ aimmath-Feature Requests-809789 ] validation using user-defined string types

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.

I have implemented this with the syntax String(mapletype), 
where mapletype is a Maple type. However, this is only a 
partial quickie solution.  A better solution would be to be able 
to specify the VProc at the c> flag in a manner similar to 
what is done for the MProc at the s> flag, i.e. to allow syntax 
of the form:

c> [validationproc,parserproc]

where validation proc is either a proc or a Maple type that 
validates the students rawanswer as string, and parserproc 
parses the rawanswer (as a string) into a Maple expression, it 
would solve all of the problems related to this topic and we 
wouldn't need these workarounds.

archive ? [Re: [Aimmath-developers] av>]

[Manolis M. <ma...@ma...>]

Hi there....

Is there an archive of  the list ? Sourceforge says its not activated... 
is it easy to activated ? Will previous messages appear ?

I am looking for this discussions that where going on about questions 
and sub-questions as I am doing some related work now. I was too busy 
back then and I accidentally deleted some of them and the documentation 
quite confusing/limited at this point.

Also can someone please tell me where I should start looking for the 
code that parses the question files and "compiles" them ?
We are converting AIM questions to WaLLiS questions but I am not always 
sure what is aloud and what is not in a file.

Thanks

Manolis

RE: [Aimmath-developers] aim home page

[Gustav W D. <gus...@ya...>]

By the way: if you send someone to the pages, please use the URL aiminfo.net
rather than the actual server URL because then they will continue to be able
to use the link after the server move.
