Neuro-linguistic Programming is based on a model of communication and psychotherapy. In ELT this model has implications for learning, as it says that we all have different learning and perceptual preferences, and in order to learn well we need to both exploit our preferred styles and develop our less preferred ones.
The teacher draws a mind map on the board to show learners the relationship between new words; in this way she is addressing the visual intelligence of her learners.
In the classroom
To exploit NLP in the classroom teachers need to use a variety of techniques, resources and methodologies to address different types of intelligence in learners. Tools as diverse as TPR, Cuisenaire rods and playing music all address different kinds of intelligence.
