Maybe, although I think those do more harm than good. Personally, I don't like the idea of requiring "explicit verbal consent" and those that suggest it don't really explain what should happen if two people just have sex (i.e. who should go to jail - most would default to the man but that's just sexist and what about lesbians?). But in any case, that's just a small proportion of alleged rape cases, all of which are much more easily and uncontroversially resolved by urging women/victims to say "no" loud and clear. The rest of the cases (i.e when someone wants to rape), I don't think can be resolved by courses or such, just like you don't resolve robberies by "teaching criminals not to steal".
