NLP Hypnotism

What if any value does NLP, hypnotism, and non verbal communication play in teaching?
NLP can be used by teachers or other presenters to engage listeners regardless of their preferred channel. Psychologists who have an audience of one, need to find out the channel(s) and tread on them mostly, but presenters or teachers have an audience that receives on all channels. Their task is to drive home their main points using all the channels so all listeners get equal substance.
The channels are visual, auditory and kinetic, so they must get people to see their points, ask them if it sounds good to them and allow them to figuratively pick it up and shake it and test it out.
Hypnotism I think may not fit in a scholastic setting.
