Effective teacher knows how to coordinate a diverse array of instructional elements and adapt them to differences in student needs, materials, and purposes.

So a more comprehensive and systematic approach is to distribute a questionnaire or evaluation form and ask students to record their reactions anonymously. Other ways is to videotape or audiotape your lessons.
