When I taught my girl (now wife) clutch and throttle manipulation we did it in a field on her Yamaha TT-R125. No issues whatsoever and by the end of an afternoon she was grabbing 2nd gear. Don't do this in a complex parking lot!!!
I think it helped that on the dirtbike I could sit behind her and work the controls with her for the first 2 dozen attempts going over all of the possible scenarios, stalling, clutchout too fast, etc..
I don't know any other way to learn or teach this than on a dirtbike though.
I'd rather ride and control an Analog bike than ride and be controlled by a Digital one.
I had previously taught the same girl how to drive a stick so I recall emphasizing the clutch's role in any panic situation over and over. I made her practice pulling that lever many times as I said the word 'clutch'..... long before we even started the engine.
I knew that if she panicked, it would be sensory overload so that 'clutch practice' beforehand definitely saved the day. '82 KZ 550... so big, heavy and fast enough that it wouldn't have ended well.
