In my teaching experience, I've tried different policies on late/absent work. Usually, the more lenient the policy, the more students will take advantage. The most effective late work policy that has worked for me is the no late-work policy. It's clear and without room for exceptions, students know there is no excuse for not getting the work done. If an instructor simply relates the Golden Rule, students will understand the true importance of getting assignments done right and on time. If we teach according to "real-world" rules, then we are preparing our students for their chosen careers.
