As a student I was send off on my own to do an hour of stalling. I don't know if that's done any more, but it's routine for the instructor to tell the student to stall and recover the aircraft (in a variety of scenarios) during recurrent training, trying out new types etc.
At my clue the rules for any of this messing about are to start at a height that enables recovery by 3,000' solo or 2,000' (IIRC).
I've had one spin demonstrated to me because I asked for it (in a 152) - not part of the PPL course. I found the actual spin to be less sick-making than the incipient spin, from which recovery was trained.
