I would like to enter into a discussion on Hands on Training vs Classroom. Having all four of the learning styles to work with I like to use state changes thru out my day in class. I will take the class into a lab area with instruction sheets and give the group the class around the diesel equipmen. The clue to make this change is when the line to the break area has started. This exercise does the trick to keep the class on task. I will look to the clock and if we haven't had a state change in the last 20 minutes it is time to do a hands on presentation. I have even at times ask the students all to stand up and do a little exercise to get the blood moving.
