Hi Andrew,

Unfortunately the plotmaple command is a static image, but if you setup a plot component in Maple (using the same plotting code), and then save that worksheet, then you can import the worksheet as an interactive Math App into Möbius (apologies, this part of our new help system is under construction, but it links to our old help page on Math Apps for now).

Then the student will be able to interact with the worksheet and move the plot.

More complex apps can be constructed and graded - see the Math Apps in Maple or our Math App Authoring Guidelines.

I am able to run the example you mentioned. However, this feedback is displayed only when the "How did I do?" option is used, otherwise, the text area remains empty after the answer is submitted.

Hi Nico,

Firstly, thanks for the effort in designing the nice questions! I would like to ask about +Quaterions_Rotation question, because of normalizing $k to get $u, the answer that the students need to enter is a decimal approximation. Are you looking to make that exact, or will you add tolerance so the student just enters correct to a number of decimal places?

I think the exact answers make more sense, so I would suggest putting certain variables in quotation marks or evaluating them using maple calls:

$length='sqrt($kx^2+$ky^2+$kz^2)';
.... $angle='$angledeg*Pi/180';

Here are two avenues of support:

Use the HTML question type to communicate with external pages: https://teachingservices.nait....I believe Digital Ed might be working on a way to import LMS assessment content into Mobius.

Thanks,

Updated basic template for linked answer boxes:  LinkedAnswerBoxes.zip

To the best of my understanding the ability to re-score miss-keyed responses is a feature request (https://ideas.digitaled.com/) and not part of the current release.  Also, and this part is something I am not 100% sure of, if Student A attempted the original question they will see the original question in their gradebook.  While if Student B attempted the "revised" question they will see the "revised" question in their gradebook.  It would be far more confusing if everyone saw the revised question, even though half of them were graded with miss-keyed answer.  To this end, I would recommend using the "edit question comment" field when manually correcting the miss-keyed student responses.

Have you tried using an array of plots?

with(plots):

A:=Array(1..2,1..2):
A[1,1]:=plot(x^2,x=-1..1):
A[1,2]:=plot(sin(x)/x,x=0.1..Pi):
A[2,1]:=plot(cos(x),x=-Pi..Pi):
A[2,2]:=plot(sin(x),x=-Pi..Pi):
display(A,axes=normal,scaling=constrained,size=[300, 300])

Although the Student ID cannot be pulled into the algorithm, there are some other great options....

1)  As Meta mentioned, you can use a combination of Adaptive Assignments utilizing Maple Repositories

2)  You can generate a "pseudo-student" id, using a response from a prior question and then generate a number from that string.

For example:  I built an assignment with the following details:

Question 1: Asks the student to write their name in the box:  "I, ___________, certify that this is my assignment".
-If a student writes a name that does not appear in the comma separated list, their first question is highlighted (as it is graded in-correct).Question 2: Asks the student to write in an ascii-string that resembles their response to question 1 (ie. name):  "take each letter in your name and convert your name to an ASCII string that is padded to a total width of 4-digits per letter: ___________________"
-we use Maple (inside a Maple-graded response) to convert all the possible student names to the same ascii-string and then check to see if the student response is correct (based on their response to the first question).Question 3:  Asks the student to (mod 5) each character in their second answer:  "Take each character in the ASCII string above, find mod 5 of the character, and indicate the resulting string below: ___________"
-Again we use Maple, to check the students supplied answer against what they should have answered based on the first question.

Basically the above allows you to completely customize an assignment based upon what the student responded in the first answer box, on the first question, (I recommend you think about using a table/Matrix with the first column as student names, and each column thereafter as answers to Question#1, Question#2, etc.)

Here is a Mobius Module that demonstrates the above:  Module.zip

Here is a screenshot of what is accomplished:

@chrisb Thanks!

@Metahofzicht

Thanks for the response. 

I found this other option as well. 

Thanks Chris

The tutors have Instructor status

I will send an email to follow up on this

The Display command uses the Typesetting package native to Maple Document mode. However since Möbius is a web app, everything needs to be converted into MathML (or LaTeX or similar) to be supported by the browsers.

The closest I can think of (with this method) is the following: $a=maple("use InertForm:-NoSimpl in a:=2(3*x) end use; printf(InertForm:-ToMathML(a));");

But I don't know if that will generalize well to the rest of your problem.

Hi cmcneile,

One solution to this would be to hold the answer in a variable. For example to calculate power = energy/time we could use variables such that $P = $E/$T. In the response area (assuming you are using numeric) you can then set "Required with" to "absolute accuracy". If you are using randomisation such that $P would be to more than two significant figures you can use the command "decimal(n,x)" in the algorithm section where x is the input and n is the number of decimal places. In this case it would be decimal(2,$P).

Hope this helps.

Hi Meta,

It seems that they have an iframe embedder feature, so it's pretty much copy-paste of their source code into source code of a Mobius question. I've attached a TA question with one of their demos as an example: Example.zip

Cheers,

Hi!

If you're comfortable with Maple programming language, you can try 'inert form'. It will allow you to grade student response in its original form, without simplifications. Click here for an example. 

Alternatively, you can convert the response to "string" and use string tools to check if the expression contains (the right number of) brackets, this should allow you to identify the expression type. I'm thinking alongs the lines of: student answer is equal to the correct answer AND the number of "(" brackets is right. 

With regards to "y=" part. It's hard to say without the actual grading code. You could try to pull the the equation apart with use of lhs and rhs commands. For example,  "y= a + b"  would give you "y" and "a+b" respectively. This should allow you to grade equation in two parts without equation comparisons. 

When assigning variable names to the equations (Maple syntax) I often forget to use ":", for example: "my_equation = y = a+b" instead of "my_equation := y = a+b". This  leads to similar error messages.

Good luck!

Anatoly
