My teaching is simple. I use a hands-on technique and am approachable to my students. I incorporate fun into my lessons when possible. And while my easy-going style is suitable for many subjects and grades, I am also able to adapt my style to the needs of the student. For instance, if I have students that are not comfortable with independent learning, I employ the facilitator style of teaching that calls for a student-centered learning approach. My colleagues generally say that I am fun but tough, and I think their assessment is accurate. A successful lesson is a lesson where my students are fully involved, listening and interacting with me and each other regarding the material presented. I plan my lessons to be thought-provoking and fun at the same time because I believe that students want to have fun and that they learn more effectively when learning is a pleasure, not a chore. I try to implement this concept into each lesson to the best of my abilities. The true measure of a good lesson, however, is when I can look at tests and quizzes on the material and see a good level of understanding and comprehension on the student’s part.
