Drawable image in (essay) question
first of all I want to thank you for having accepted me in your community.
I'm trying to make out a question which allows the student to draw something, e.g. a qualitative graph of a function given its analytical expression. Moodle allows to do something similar, but only in the spirit of automatic correction: the system checks how much of the image plotted by the student overlaps the image which has been given as the correct solution, and gives a grade that can be either positive or negative based upon a certain threshold, which cannot be set at a lower value than 30%. This method does not fit very much our needs, since a qualitative plot does not require an exact precision (in the case, I possess several screenshots showing how solutions which are intended to be correct are interpreted as a failure) . So we would focus our attention on manual grading, with the graph that has to be interactively plotted by the student inside the platform, but evaluated by a teacher which would receive it, leaving the overall score pending until this is done. Is there a way to do something similar in Maple T.A.?
Thank you in advance, and best regards.
Hi @afullo. I think there are three options that I can think of in order of difficulty.
1) The scanned document question.
2) Sketching question type with a weighting of zero but then I think the grade can be changed later in the gradebook.
3) HTML question type using a canvas element for recording hand drawings – one issue is it will have to always give the grade of 0 but can be later marked in the gradebook.
Thank you @jmtrik ! I will evaluate the option which better fits our necessities and I'll try it.
