My experience has made me a better instructor, I have had students that when they came into my class I put them into a slow learner catagory. When in fact they have proven me wrong. Given the proper approach and the excellerated learning techniques I have learned, Only what the learner can reproduce has been learned, Hands on, auditory, visual, stimulation throughout all demonstrations. Demos done Instructor led Student performed demos. Entire class open to questions and movement to gain better visual of projects.With all of this I have seen more success with my students as well as less damage to training aids. The funny thing is how often that prejudged student jumps up to shine in the class.
