It was mandatory when I studied at Wageningen University (an agricultural university in the Netherlands) in the 90's, the subject was called 'wetenschapsfilosofie' (philosophy of science). It was not taken seriously by most students since the way the subject was taught and tested was not very inspiring, to pass the test it seemed to be enough to intersperse dense prose with the names of some well-known philosophers - Popper being the king here.
