Garry Mitchell’s The Trainers Handbook (1987) recognized ten principles of adult learning: People learn only what they are ready to learn. People learn best what they actually perform. People learn from their mistakes. People learn easiest what is familiar to them. People favor different senses for learning. People learn methodically, and in our culture, systematically. People cannot learn what they cannot understand. People learn through practice. People learn better when they can see their own progress. People respond best when what they learn is presented uniquely for them. Each of us is different. As a Sales Manager, choose three (3) principles and share how they can be incorporated into an effective Sales Training Program.
