In preparing for this type of question, list your strengths. You can narrow them down by thinking about how they help you as a teacher. Think of situations where your strengths help you shine, such as dealing with an unmotivated student or when teaching a topic that most students would find uninteresting. For example, if you are an encourager and motivator, you could say that you love coaching your students. Give a specific instance, such as working with a student who was unmotivated and failing the class. This situation could incorporate multiple strengths, such as being strategic and observant, seeking to understand the problem and then coming up with a way that worked for the student to help empower them. Using examples helps the interviewer get a better picture of your strengths in action.
