Dutch universities have an arguably peculiar academic calendar: each semester breaks down in two blocks (actually 3, but only 2 are teaching blocks) so 4 blocks in total. Each full course is block-long (around 32-36 hours per block, usually 7 teaching weeks with 4-6 hours per week) which might seems short and "rushed". Each such course is 4-6 ECTS.
When I am talking with some other Dutch colleagues, they are not exactly able to justify this but they claim that "is about quality, not quantity". Sure, but how can you teach, for example, Calculus in 34 hours total including tutorials etc.? (I am using the example of calculus because they try to fit in such a course single and multi-variate calculus, series, differential equations etc.).
Anyway, I am wondering if there exists any particular study or report that argues that is more beneficial to have more blocks with fewer hours per block/course than the traditional break-out of the academic calendar.
I am not sure if other countries have similar systems, Netherlands is the only one I know so it might be country-specific.
