On how to deal with the fact that students are busy (this is useful!)
Formalized Extensions and Pedagogies of Care
"The first new feature of my pedagogy of care is a formalized 12-hour grace period for every course activity and every formal, graded assignment. This allows for the technical problems that constantly emerge and it tells students not to worry if they are a few minutes or several hours late because of children, work, or whatever.
Another change I am finding successful is substantial use of sign-up sheets. Students select their due date — multiple due dates are available almost every week of the semester — for projects that ask them to present and analyze important objects, current events, or primary sources, all also of their choice.
Formalized extensions are having the most impact."
