I believe that learning mathematics involves two key elements. The first is the understanding of a concept, and the second is the application of knowledge to problems. The two complement each other. One might first learn a bit about a concept and then strengthen the understanding of this via applying the knowledge to solve problems. Or one might learn a concept solely by solving many problems and then generalizing the common details to come up with a deeper understanding of the more general concept. Practice is especially important in order to succeed in maths exams and I go over many exam-style questions step-by-step, explaining the key idea behind every step.
However, every student learns differently and my approach is flexible to the needs of each student. Learning mathematics involves building upwards. So I believe it to be very important to address any weaknesses the students may have first before moving on to new material. I aim to keep a friendly atmosphere during my lessons and to ensure that the students feel at ease to ask me any question regarding mathematics. I am a firm believer that there is no such thing as a stupid question, and I also believe that the optimal way to learn is by asking questions.
