I don't know.
I was involved at teaching introductory physics at a famous university and I was 100% proud of what we did. The conventional course had a few hundred students but between (1) a Nobel-prize winning lecturer who I think did a good job, (2) an ex-marine in the back room who maintained awesome demonstration equipment, and (3) a large team of section and lab TAs that broke out into small groups I think students got a lot. There also was an autotutorial class that forced students to learn the material better because it would not let them progress with a bad grade; the results were well documented but some students found it nerve-wracking because it would force them to revisit work they found hard.
That's my opinion, though, as a TA and a person who always found physics easy. If you asked 50 students about these classes, however, you might get 50 different opinions.
A friend of mine who now teaches at a small Christian college, takes undergraduate education seriously, and cares about the general flowering of his students was a TA in a similar course in another quantitative department in the same Uni and he was not happy with the quality of the intro undergraduate course he taught.
