we estimate the impact of class size on the final exam marks…David Wolman on diploma mills. Read it and count how many times those in positions of power choose the easy way out instead of the right one. HT: Ben Miller
The effect of class size on students’ performance is – as expected – negative; students do worse in big classes…
If moved from a very small class (of size 10) to a very large class (of size 150), the average student can be expected to suffer a loss corresponding to about 50% of the overall variation in exam marks the average student experiences across all of her courses…
Reducing the size of very large modules (above 100) could be a cost-effective way to improve students’ performance. For modules in the range 30-100 reducing class size could be a rather ineffective strategy, while for classes below 30 it could be a valid but not necessarily cost-effective strategy…
here appear to be at least two ways that larger classes reduce students' performance. First, changes in student behaviour such as their attentiveness or participation. Second, reduced resource availability, such as library books or faculty time during office hours…

One of the most sensitive issues discussed was whether there are too many graduate students or programs. At the forum, one professor got up and said he was morally troubled by the decision of his university to expand its history graduate program at a time when graduates weren't finding jobs…The red carpet treatment. HT: Edububble
one issue was declared off limits by the AHA: any effort to evaluate program quality and to do some sort of "certification of programs" so prospective students and others could determine whether they were worthy.
Bender said he remains concerned that -- even without such a certification system -- prospective students don't have enough information…
