Tasty Research has a fascinating look at the effectiveness of self-imposed deadlines. Students were given the option to set their own deadlines for three assignments in a course. As noted, despite the theoretical appeal of putting all the deadlines on the last day of class, only about a quarter chose that option. Apparently, it’s a rational-enough choice to set some earlier deadlines for some of the work in order to not feel that deadline pressure!
I’m already committed to my classroom deadlines and timetables for next year, but I’ll be looking at this research with an eye towards what it might tell me for the future (as well as my own work).
