A last-minute idea over the weekend. (Well, an idea I had in June but decided now to act upon.) A question to pose to some of my students, one that I wanted them to think about rather than answer spontaneously in class. A deadline. So I put the question on Moodle as an assignment, and e-mailed the classes about it. By this morning (Monday) I had received significant feedback, before I even set foot in the classroom.
Quite a difference from when we first started to incorporate "tecnology," and students balked at the idea of e-mailing an assignment to me.
