What do you want to practice?:

o Derivatives

o Integrals (multiple choice options)

If the student choose Derivatives, a derivate appear to be solve. If the student choose Integral, an integral appears to be solve.

Is this an addaptive question type? How can I create it?

]]>I would like to see the possibility for adding moments. It's is missing ;-)

]]>The following algorithm works for a question like "find the derivative of sin(f(t)), assuming f is differentiable":

$g=maple("sin(f(c*t))");

$ans=maple("subs(c=1,diff($g,t))");

This will enable students to enter their answer symbolically using f'(t).

***notes: the question ignores annoying spaces the student might add into their response

This is what the question looks like:

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.

]]>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';

I see here that, also in List questions and not only in Multiple Choice questions, *for each specified incorrect answer, it can be defined response-specific feedback*. But I'm unable to find the option by editing, and manually adding in the source code rows of the kind *comment.<n>=<comment_text>@*, as proposed here for the MC case, does not work. How can I perform such an addition?

Thanks in advance.

we were talking about designing an adaptive question with multiple choice, with the feature that, in case the student answers wrongly, in the subsequent adaptive section a text dependent on the given answer appears.

For example, the question may be: "which of the following football teams is not an English one?". If both Chelsea and Liverpool are among the alternatives, then if Chelsea is answered we would like to show a consistent text as it would be "wrong: Chelsea is a district in London", while if Liverpool is answered the text would be like "wrong: Liverpool is a city in England".

Unfortunately, response-specific feedback does not fit for this case, since it is shown while the question is *evaluated*, that is, at the very end, not while the question is *verified*, i.e. when the correctness of the answers in the current adaptive section is checked.

I guess it would require to catch the answer given by the student, after having assigned a text to every (wrong) alternative, but I don't know how to perform it; I worked with chained questions in the past, but there a specific question made use of the answers given in a previous question, not in a previous adaptive section belonging to the same question.

Thanks in advance, best regards,
