The POGIL model was developed for use in the sciences and has been used successfully in a variety of chemistry courses; in biology, anatomy and physiology, physics, math, computer science, and environmental science; and now in other fields such as education and marketing. 

In this model, the instructor functions as a facilitator who’s available to assist the groups. However, instructors do not answer questions that students should be able to figure out for themselves. Rather than answering student questions, instructors opt to ask the group questions that lead them to the answer. Students are assigned roles in this model.
