We all have students that want two weeks to attempt their project but then either wait till day 13 to start of miss entirely. I commonly will not assign a project in total with one due date but rather break it up into smaller pieces with a succession of due dates. A little done here and a little done there can lead to the entire project 's completion before they know what hit 'em. It is also easier to stay on top of those that need closer attention this way. I know if they are making an honest attempt or not. It has been much more successful compared to my earlier, more traditional assignments.
