Students must be Junior or Senior Biology or Biology Education majors to enroll. Permission from the Biology Coordinator must be obtained prior to enrollment. Students will assist the Laboratory coordinator and Laboratory Instructor by assisting in teaching a laboratory section of Introductory Biology. BIO 491 students will take part in weekly instructional activities during weekly class meetings that will emphasize preparation for lab and discussion of topical instructional strategies. The undergraduate teaching assistant (TA) will also assist the laboratory instructor in one laboratory section and have the opportunity to be an "apprentice teacher". TAs will master the material taught in the lecture course, develop and teach good quality laboratory and study habits, and acquire experience teaching. TAs will gain valuable work experience by assisting the lab instructor with lab management and organizational issues and assist enrolled undergraduate students with mastering the lab competencies required.
