Behaviour training is very common for customer interactions, health and safety, or many procedure based activities. When I moved from education to business and organisational communications, I was surprised how common presenting ‘bad’ behaviours followed by the required ‘good’ behaviours was in training materials.
Only occasionally does bad v. good occur in education. Would you expect a maths teacher to spend a lot of time showing you the wrong way to arrive at a solution, before showing you the right way? Would you expect a science teacher to show you the wrong chemistry procedure, before showing you the right one? Probably not, so why is there a difference in organisational training?
