I typically distinguish between exercises and assignments. While I grade exercises for completness this is just a check list approach. I use rubrics for assignments. In this first assignment, sequence, message passing and use of story telling features are explored. Students are expected to be creative and original. No art experience is required for full marks. I've included a single page handout and the video demo I make available to the students. I'm currently using Moodle as part of my course in a "blended" program.
