<p>Instructors should integrate as many resourse as possible into the learning environment. Something as simple as a cutaway of a component or a vdeo could be the trigger for some students. I cover reaar drive axles in my course and TORSEN is one I have to explain. I first demondtrate to the students how an adjustable wrench works, which is something most are familiar with. Then I apply that understanding to the TORSEN. They both work on the principle of worm gear /worm wheel.I still have a few who struggle with it so I have them view a video online that explains the principle. What I am really trying to teach them is to apply critical thinking skills to what ever the task is.</p> <p>&nbsp;</p>
