Note favorable comments, and try to build on those points when you teach again. Reading through unfavorable comments may be difficult, but they provide important information as well. If you have modeled appropriate constructive criticism as an instructor, you can hope that your students will provide feedback in an equally productive manner. Peer Observation Peer observation is not a common practice but it is helpful to have a colleague observe your class or review your syllabus and other materials. Plan to share this task with other trusted TAs and learn about teaching by observing others.
Some departments require all TA-led classes to be observed at least once by a faculty member.
Observation by a faculty member can be very useful. The faculty member who observes your class can provide you with helpful hints about aspects of your teaching. If you intend to pursue teaching as a career, have faculty members observe your classes a few times. Faculty who have observed your classes may include their comments about your teaching in recommendation letters and such comments would be valuable if you plan to apply for teaching positions. Keeping a journal also helps instructors keep notes about ideas to incorporate into class, points to cover, and aspects of professional development one can forget in the midst of the semester.
