From my teaching experience I have learned to remember to reinforce the new material (concepts and equations) as well as still remind the student to be mindful of their base knowledge (converting units for example). I was shocked after one exam when i saw I had a group of students who had all the engineering concepts applied correctly and had errors when it came to converting the units, even though units were discussed as part of the first lecture.

I do think I need to increase awareness (my own and the students) of the learning process, to help students think about the way they are thinking. I do try to present information in different ways to encourage them to think about the concepts but I need to follow up more with questions of how they understand the concept rather than explain my understanding over and over.
