As a junior or senior, you can assist in a freshman or sophomore-level lab course under the direct supervision of the course instructor. This is a great opportunity to develop your teaching and communication skills, as well as find out what is involved in the preparation of a lab. Your specific duties will vary, depending on the course you're assigned to-it'll be a course you've already successfully completed.

Because undergraduate teaching assistants relate well to first-year students, you'll help bridge the gap between first-year students and the instructor. If you're interested in assisting in a course, talk to the course instructor no later than the middle of the term before the course will be taught.
