Indeed. Teaching a student how to Select Hold Trim can be kept pleasantly simple - bearing in mind that it is about attitude flying rather than level/flight path. Displacing a trim control while a student is flying is incredibly poor technique for so many reasons! Far easier and more productive to displace the aircraft into a new attitude, trim, and then give the student control to reselect the original/Datum attitude and note the force required to hold it. Thennnn teaching Coarse -> Fine trim control. I see a significant number of pilots on either training or test flights try to hurry trimming and never actually complete the process, because the finesse was never taught at the initial stages.
