## How to check input in Maple TA?...

Assume the inequality xA,2+xB,2+xC,2 ≤ 110 has to be entered as "symbolic entry only".

How can I check that in Maple T.A.?

It seems that there are type conversions necessary. I attempted to use the MathML package without any luck.

1. Tried to transform \$ANSWER within the answer field using MathML[ExportPresentation]( x[A,2]+x[B,2]+x[C,2] <= 110) and compare it with evalb((\$ANSWER)=(\$RESPONSE)) in the grading code field
2. Tried to transform \$RESPONSE in the grading code: evalb((\$ANSWER)=( MathML[ImportContent] (\$RESPONSE)))

What’s the format of a symbolic entry? Is it really MathML!?

What is the correct way to do it?

3. expression type: Maple syntax?!
4. Text/Symbolic entry: Symbolic entry only

## How do you check that the correct inequality was p...

Assume you want to check that the following inequality was correctly derived:

xA2+xB2+xC2 ≤ 110

How can I check that in Maple T.A.?

If I use a Maple-Graded questions, what must be in the answer field? x[A,2]+x[B,2]+x[C,2] <= 110 !?

## Indexed variable...

How do you check an indexed variable in Maple TA?

For instance the question might be: enter 6x1   (or 6xA1)

I have tried using a Maple-graded question specifying as correct answer 6*x[1]   (or 6*x[A,1]) without any success (works only for 6x).

## display only content of a matrix ...

How can I display in Maple T.A. the content of a matrix as pure text?

matrix([[1, 2], [3, 4]])

1 2

3 4

Is there a solution without using Mathml and hopefully without using StringTools?

And can I assign the rectangular text display to a variable (including line feeds)?

My first attempt in Edge and Chrome was not promising.

## Graphs in the Question Designer...

I am trying to design a question, where studenst have to find the equation of a linear function given its graph. For this to work, I have to be able to draw gridlines, which for some reason is not possible in Maple TA with the ordinary plot function. I know it should be possible using an applet; given the problems this is going to create with all the different browsers, however, this is not a viable solution. I have found another solution which is unreasonably complex but should work. The problem is that sometimes it doesn't work. When I press Refresh algorithm preview in the Question Designer I get "Broken Maple plot. Verify your plot statement" roughly every third time I refresh the preview. Any help would be greatly appreciated.

The algorithm is here:

\$a1=range(-4,4,1);
\$a2=range(1,4,1);
condition:not(eq(\$a1,\$a2));
\$px=range(0,5,1);
\$y0=range(0,5,1);
\$x0=if(gt(\$a1,0),\$px,-\$px);
\$f=\$a1/\$a2*(x-\$x0)+\$y0;
\$G=plotmaple("
plots[display](
[plots[coordplot](cartesian, [-10 .. 10, -10 .. 10], grid = [11, 11], color = grey),
plot(\$f, x = -10 .. 10, y = -10 .. 10, color = [green, blue, red], thickness = 2, tickmarks = [[1], [1]], labels = [``, ``]),
plots[textplot]([0, 10, 'y'], align = {above, right}),
plots[textplot]([10, 0, 'x'], align = {above, right})
],
labels = [``, ``], axes = normal, view = [-10 .. 10, -10 .. 10]),
plotoptions='width=350,height=350'");
\$g=gcd(\$a1,\$a2);
\$at=\$a1/\$g;
\$an=\$a2/\$g;
\$a=if(eq(\$an,1),\$at,\$at/\$an);
\$ans=\$a*x+(\$y0-\$a*\$x0);

## How do I fix the error message ?...

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?

Thanks

## How-To Webinar: Question Chaining in Maple T.A.

by: Maple T.A.

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.

## Error with multiple choice creation...

Hi,

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?

## Student input as variable in Maple TA assignment...

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.

## Same random parameters in different assignments Ma...

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)

## How can I fix my math expressions in T.A.?...

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

sig2=maple("MathML:-ExportPresentation(\$sig1)");
