Maple T.A. Questions and Posts

These are Posts and Questions associated with the product, Maple T.A.

I have written a Math App in Maple to create a Math App question in Maple TA.

The app has two tables, a plot area, and text box. The first table provides the data to the students for calculating their answer (and so Editable in the component properties is unchecked). The second table is where the student enters their answers (and so Editable is checked). The text area and plot area are for providing some real time feedback and error checking to the students.

Everything works fine in Maple.

In Maple TA I have tried using both a Math App question type and a Question Designer question type with a Math App inserted. I have tested it in Internet Explorer, Chrome and Firefox.

In all six cases when I click on one of the editable table cells to put in an answer a popup appears with the error message: "Unable to update RTable due to error=TypeError: window.parent.parent.updateRTable is not a function"

I am using Maple 10 and the latest hotfix is SP-002.

What I have worked out so far is that the Maple TA web page is designed so that the Math App sits in an iframe and each table sits in a separate iframe inside that iframe. updateRTable is a function inside the tables iframe that calls the updateRTable on the top level window and if this fails gives the error message above.

The top level window includes the file /maplenet/js/worksheet.js, which includes the function updateRTable.

How do I fix this error?


As an educator, you surely know that giving students more involved problems in an online assessment tool provides challenges, both for students and instructors. Only marking the final answer doesn’t necessarily provide an understanding of the student’s capabilities, and it penalizes students that make a small mistake in part of their solution.

This webinar will demonstrate how to create separate questions with multiple steps that can be linked or chained together. Question chaining allows instructors to mark subsequent questions based on the correct answer or the answer provided by students in previous parts.

I have a problem with the adaptive question designer: when I use the multiple choice question type then occasionally parts of the question environment appear multiple times in the text, duplicating each time I reopen the question to edit. This happens in particular if the answers are a bit longer (4-5 lines each). So far I couldn't figure out how to fix this, does anyone have a similar problem? 

Many thanks for your help!

Is it possible to have an input box, where the student can give an input (integer) and this is then used in the following questions in an assignment?

e.g. in the first question the student is asked to give his student number, in the second question this number is used to create random parameters.

In Maple TA in blackboard I am creating an assignment. Each week a part of the assignment will be posted. I was wondering if it is possible to have the same random variables in differnet assignmemts. That way the students can use their prior work. 

So in week one the students will get a set of random variables. But in week two a new assignment is posted were I want the same variables to come up for each student. Is this possible? (all students will have their own unique set of variables)

Maplesoft will be hosting the 2015 Maple T.A. User Summit this June 15 - 17 in New York City. Don’t miss this opportunity to learn about new trends in online education while networking and socializing with fellow educators and Maple T.A. users in the city that never sleeps!

I am writing here because of a problem with writing mathematical expressions in Maple T.A.. I have been using it since two years, and I have a lot if questions created in version 9.0 and 9.5. A few months ago my university installed T.A. 10. At the beginning there were problems with the connections between T.A. and the Maple server. After the administrators got over these, there were another problems.

There are a lot of questions where I use greek letters, for example Sigma. Earlier it was easy, I wrote

in the 'Algorithm' section, and I could write

in the Text of the question. The letter had a perfect italic and bold style, like as it would be created with Equation Editor.

Now I have to write


Maple T.A. 10 introduced two new question types: Sketch and Free Body Diagram. To assist users in learning the new question types, Maplesoft has created a few hundred samples to look at. These sample questions are already featured on the Maple T.A. Cloud, but you can also download the course modules below. 

Sketching Questions - This course module contains 309 sketch questions. Areas covered include: functions, exponential functions, inequalities, linear equations, logarithmic functions, piecewise functions, quadratic equations, systems of equations and transformations of functions.

Free Body Diagram Questions - This course module contains 118 free body diagram questions. Areas covered include: Electricity, Magnetism and Mechanics.

I am trying to write a question which asks the student to convert a random decimal number into hexadecimal. I can't get MapleTA to recognize that a correct result is input. I think the problem is that I am not correctly dealing with the hexadecimal number which is represented as a symbol from convert.  

In the algorithm section I use:


The question was:

Convert the decimal bumber $dec into Hexadecimal.   

In the text input section I use:

is(($RESPONSE)-($hhh) = 0);

in the grading section of a Maple graded part of the question. I have tried converting the $RESPONSE to decimal and comparing with $dec.

I allow the students 4 attempts at each question, so I don't want to do a multiple choice question.







The following is taken from p 328 of the Maple TA manual.



% This question uses randomized variables.
\qutext{Find the formula for the inverse of the function
% The above code chooses random integer coefficients a and b between
% 2 and 10.



Running it though the online compiler generates the following when Service Pack 1 checkbox is UNCHECKED

Are there any topics you’d like to see us present in 2015? Make sure to leave us a comment with your ideas!



Is it possible to insert comments within algorithms in Maple T.A. questions? I'd like to add some words or annotations which won't be read by the compiler, to make the code easier to understand.
