Another online assignment due today. A one page problem on the current module.
35% failed to turn anything in
29% earned a perfect score
The rest ranged from 9/10 to 2/10
How's that for a bimodal distribution?
If it makes you feel better, I often have that same result from my face-to-face science for teachers classes, even when we did the work in class in groups and I stood at a couple of the tables prompting, "And what comes next?" Failure to turn in papers that I did everything but move their hands on the paper for them is my most annoying issue (dude, I am trying to give away points here!). Second most annoying is leading a group of 4 people step-by-step through the entire assignment only to have 3 perfects and 1 near zero.
If you have a 29% perfect score, then I would say you're doing ok. Although, perhaps a mass email to the non-turner-iners is in order. When I do those emails, I mention the failure to turn in recent assignments, explain what a making-progress grade in class currently is, and exhort students to check their current course grade against that standard.
As we come up on the final withdrawal deadline, I send personalized emails with current grade in class compared to the minimum likely-to-pass grade for those who should withdraw. Doing so doesn't do a lot for the students, but it makes me feel better that I've done all I could.
