Hello,

 

I have an issue while permanently deleting students from the system, the MapleTA 4.0 enviroment report this error:

An unknown error occurred when uploading the roster file: "com.maplesoft.mapleta.persistence.service.profiles.exception.ProfileServiceProviderException: org.hibernate.exception.ConstraintViolationException: could not execute update query". Please see the roster.log file for more details. 

Well I had been using MapleTA for a long time now, and I'm really satisfied with the product itself and the e-Learning idea.

So i would like to use a MapleTA question in plain html, not in Blackboard neither in Moodle (that would be great at my college), but in plain html.

 

Imagine a web version of an Algebra book in wich it's shown how to invert matrix (something everyone must know when finish high school but nobody remembers in the first week of college), and at the botom there is a random problem when you can try to do it.

Is it possible to write questions of MapleTA just from maple 11?

I mean, I know is possible to write questions and export them to Maple T.A. but every "execution group" will be a diferent query for the maple and setences like

RandomTools[Generate](integer(range=0..4));

will return always the same number, an i cannot use sentence like parse(time) because parse is restricted.

Thanks.

In a test we had develop at our college, we need to use some MathML expressions on the questions, for example: to verify if an student know the sine law I use:

mode=Multiple Choice@ name=sine@ editing=useHTML@ @ answer=1@ choice.1= @ choice.2=@

I'm making questions for new mathematical students, to know which is their level and then help them in his first year, but i have a problem; I want to know if they are able to simplify an operation, i.e. 4/6 i want them to write 4/6 with MapleTA i don't know how to do that, because a maple Graded question or a formula-enter question gives both valid, and i don't want to use string compare (because "2/3" is the same as "2 / 3" but it's not the same string..., if there is no other solution i can use maple to throw away the space character...") Anyway, there is somebody that knows a smart way to solve that problem?
