For one thing, I also give at least 2 (usually 3) nights for video-watching homework assignments -- no more than two per week. That helps to address potential technology access problems, but also it allows for my students' crazy over-scheduled lives. It's really not their fault if the hockey rink isn't available until 8pm, or they have to travel 1 hour every Wednesday to the other parent's house, etc.
Regarding projects, this year I tried something new that appears to be working. It's kind of weird, so please don't hate me immediately ... Students don't have to make a final draft. In fact, they MAY NOT turn in a typed, polished finished product. I want dog-earred copies of notes, scrawled and scribbled outlines, pen mixed with pencil -- whatever they could do in 4 or 5 class periods!
