To address the challenge of actively teaching to a high enrollment class, the project lead will hire undergraduate instructional assistants for Chemistry 2410 to attend lecture/discussion and assist students with problem-based learning (PBL). The material is adapted from process oriented guided inquiry learning (POGIL) activities that encourage student to take responsibility for their learning. Research has shown more learning takes place when an idea is developed by the student, rather than being presented by an instructor. Lecturing takes place only to introduce a topic or to reinforce or to expand on previous topics.
