My teaching method is primarily practice focused. If we are covering a new topic, of course I will go over it before getting to problems, but when it comes to revision of a topic that a student has studied before, I find that doing practice problems is the best approach to learning.
In my experience practice problems are a good way of uncovering exactly where a student may be misunderstanding a topic which is useful for deciding on the direction of the lesson. I also find that a more interactive approach ensures that the student is really paying attention, and the knowledge is retained better than it would be if it was presented in the form of a lecture.
If a student is really unable to answer a certain question, I like to ask leading questions that allows the student to discover the correct answer themselves, rather than just explaining how they should go about it, because I think there is a better understanding in cases where students have discovered the correct method themselves.
I also think that going over past papers or tests and quizzes done in class can be worthwhile, as it ensures that the lessons are directed towards a concrete goal, which can help to motivate students.
