Which method is used by instructors to maintain and improve their teaching skills and mastery of subject matter?

The method of maintaining and improving teaching skills and mastery of subject matter through experience, study, and professional development is fundamental for instructors. This approach emphasizes the importance of continuous learning and adaptation in a teaching role.
