On the positive side, though, is that out of 46 students who handed in the total of 16 written assignments each this semester, only one student tried to plagiarize on a single assignment. And this was a student who missed most of the course. Everybody else struggled with the material honestly and without Googling anything.
Thirty-nine out of 46 students did quite well. I think this is a very good result for an intensive summer course where we cover the material of 15 weeks in 5.
