What are the flaps there for, if not to be used during landing (and preceeding phases like approach and final)?
Landing is the very RAISON D'ETRE for flaps, and a beginner pilot should first learn to land in the normal way. Normal = according to NORM = POH, which will say a certain degree of flaps for most planes in most circumstances.
Further on in training you can and should practice exceptions - both to prepare for the day your flaps fail on you, and to make you a better pilot generally.
BTW the craft I was flying today (

BTW a training organisation where instructors don't speak from one mouth is suspect. A training organisation where you are bullied by an outsider to your training is a no-no.
