Will you please design my course? Pretty please? Possibly your students could earn credit by helping to design course content for instructors. Years ago, I designed a Course Manual for a newly designed course that included weekly assignments by utilizing icons to note whether the assignment was video, written, or reading materials. I think that using icons as indicators is a very wise choice and I realize that it's important to be consistent in their usage.

It's challenging enough to come up with content, let alone make it look good!
