Such insights can be useful as you help your students learn the material. You have the enthusiasm and fresh insights of a new arrival to the profession, which is one reason why some undergraduates have said the best teachers they ever had were TAs. This teaching experience may be an important part of your education as a future professor. Even if you do not aspire to be a professor, you will develop poise and self-assuredness by standing before a group, thinking on your feet, having to organize and structure information, and developing other skills that will benefit you in whatever career you pursue. The lesson plans, lecture notes, and other preparation you make for your TA assignment are likely to be useful to you later on.
Teaching can be a rewarding, creative act.
Because TAs frequently work with new freshmen, you are important in their adjustment to college and will contribute to their first impression of both the university and your academic subject. At a large research university like Iowa State, the small groups that you teach in recitation sections, labs, or studios may help to reduce the impersonality of the place for these students. Your collaboration with the faculty member who supervises the course is a valuable experience. He or she may be a source of useful advice on teaching. If you develop a good working relationship, this faculty member may become a mentor during your graduate career and a reference for you when you search for your first position after graduation.
