I am looking to set an economics task where I want students to show their understanding through drawing diagrams on paper so that it can be done in timed conditions. What is the easiest way for students to do this (while working under a bit of pressure from timed conditions)?. Is there a way for students to activate their device camera to take a photo as a file submission or do they have to photograph the graph they drew, save the file somewhere and then submit it that way? This is to cater for students learning remotely. Looking to have multiple submissions for the task.
