I am at the last here of my phd in theoretical physics at KU Leuven. In the last four years I have been teaching assistant in several classes of the master degree in physics. My goal in teaching is to drive the student to a full understanding of the sabject. No matter how difficult a physics or math problem looks like, if you unferstand it, you solve it and maybe even start to like it!And if you understand it, you learn! My strategy is to translate the problem to daily life experiences and/or to show to the student applications of what he's actually doing.
