Hi Everyone,
I think this is significant. I took CS2390 in the Winter Quarter 1998. I was one of the few people who used MVC in the first project which was a design documentation project but no code to be written.
However, I missed part of the questions on MVC on the midterm. I think I did not really have a adequate understanding of how MVC works in Squeak even though I had used it on a few small programs in Java and C++. I am not even sure I understood MVC that well.
My guess is the students this quarter probably had a much better understanding of MVC by the time they took the midterm.

Last week was the midterm exam, and again, I included a very similar problem to ones I've used before. Here are the results for the last four offerings of this course (grades normalized to between 0 and 1.0).

Is the Spring 98 Quarter (now) *REALLY* better than Winter 98? I had the same grader and the same grading scale last quarter and this. I did a one-tailed T-test on the two sets of grades datas. p=4.4E-13 is much less than 0.05, so I think I'm safe claiming statistically significant difference.
I plan to write a technical report on this soon, but I thought that y'all might be interested in some raw, early results.
