I like spinning but question the validity for a student PPL. About the only time a virgin PPL will get an aircraft in a spin is in the base-final turn scenario. In all reality, if the pilot has failed to recognise all the previous warnings of impending stall/spin, it is extremely unlikely that they will recover from a spin that started at about 500ft agl. I much prefer hammering home how pilots can recognise slow flight, high AOA etc.
That said, if a student asks me to demonstrate one, I will.
