I like to use as many different strategies as possible in my teaching as I can. From Reading to lecture to questioning to hands on. I feel as each person is different in that they will percieve ideas differently, they will also see things one way in text but when they get to the training aids or equipment not be able to comprehend the same material. The discovery also of how a student can see where his understanding truely is by reading about it, hearing the lecture, seeing the schematic diagram yet still not fully grasping the concept until they assemble it themselves and can put it all together on their own. then you get the AH HAH moment!
