Students enrolled in this course attend weekly pedagogy sessions led by the instructors and facilitate a weekly PLTL session (1 hour) for a pre-assigned group of 8 to 10 students from CHEM 111 or CHEM 112. This course trains students to become effective leaders for Peer-Led Team Learning (PLTL) groups in the large enrollment general chemistry courses. The weekly pedagogy sessions will equip students with collaborative learning strategies, group facilitation techniques, leadership skills, and communication skills.
