I am using STACK for grading of simulation homework with finite element programs. STACK is used to generate individual parameters and to check particular response quantities based on fitted metamodels or analytical solutions.
However, I 'd like the students to give proof by screenshots. Initially I asked them to hand in a pdf with the documentation of their work (in a separate assignmen). The problem is: It is a pain to check the correct use of assigned parameters between Stack and Pdf.
I found out that I can add essay questions to the quiz. The students can upload files which I have to open in a separate application. It would be much easier to review the homework if I just had the images embedded visibly in the quiz review page. It even seems that the editor for essay text fields accepts insertion of images, yet these are removed upon handing the answer in.
In the tracker issue https://tracker.moodle.org/browse/MDL-48611 my situation is described very well.
Yet the issue was closed without even adressing the problem. Attaching files is possible but is a pain for review.
So the question remains: What is a clever way for embedding students images in quiz responses?
Could another STACK input type do the job (perhaps with manual grading and option to give comments)
