I am developing a learning control system, where I will have a database of questions that will be listed in an activity and subsequently answered by students. As soon as the student answers the question, I would like to store whether he hit or missed the question.
The key point of my system is to allow a follow-up of the student’s learning, so I thought I’d store in the bank the number of questions he missed and got right from each topic. My problem is how to demonstrate this in the DER.
