An Interesting Group Work Model

It has a long, not-easy-to-remember name: Process Oriented Guided Inquiry Learning. It usually goes by its acronym: POGIL. It’s a model designed to replace lectures (though not necessarily all of them). Students discuss course material in teams, and they use carefully designed material that involves sequenced sets of questions—that’s the guided-inquiry part of the model. The process part relates to what is generally a three-phase learning cycle that involves exploration, invention, and application. It is derived from Piaget’s work on mental functioning.

In the exploration phase, students usually start with a model and the questions help them see patterns within the model. “Often, the questions lead students to test hypotheses or explain the patterns and relationships found in the model.” (p. 263) The invention phase involves introduction of a concept or relationship. In the application phase, students are challenged to extend and apply the concept to new situations. “The sequence of questions in POGIL materials are carefully devised to help students progress properly through the phases, to guide them toward appropriate conclusions, and to develop desired process skills, such as problem solving, deductive reasoning, communication and self-assessment.” (p. 236)

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. The website (http://pogil.org) shows sample materials. For those interested in the model, the website contains much useful information, including a detailed instructor’s guide that can be downloaded for free.

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. There is some variation in the roles, but there might be a manager who keeps the group on task, a scribe who is the group’s official record keeper, a spokesperson who may be called upon to share the group’s solution, and a librarian who may be the only person in the group permitted to have the textbook open.

The POGIL model has been studied empirically in a number of courses. Here’s a sample of the findings. In organic chemistry, less than 8 percent of more than 1,000 students were negative about the method. The same cohort had 30 percent registering negative attitudes about traditional lectures. In an anatomy and physiology course (see reference at the end of this article), grades improved at statistically significant levels. In a medicinal chemistry course taken by pharmacy students, exam scores for students in the POGIL section were higher, as was the final grade distribution (see reference at the end of this article).

This not a method that can be undertaken without significant planning and preparation. The anatomy and physiology professor writes, “Although POGIL requires a great deal of effort and a careful introduction to students who might be skeptical of a novel and unfamiliar classroom experience, its benefits cannot be easily disputed.”

Do you think that students come well-prepared to class to use this type of learning design? Much like group projects, I have found that there is a disparity among participants' levels of preparation which could present challenges. Does this model propose a method for ensuring students are ready to take on their roles and participate at a level that is good for the group? And is this model in practice at all levels (undergrad and grad)?

Thanks for sharing the info and references.

Are there any workshops on student-centered learning scheduled for the summer?

Mary Bart | May 29, 2012

Hi Margie,
The next in-person workshop dedicated to student-centered learning is in January 2013. More details coming soon at http://www.facultyfocus.com/workshops/.

We also have a number of online seminars scheduled throughout the summer. The ones for August aren't posted yet, but you can see the schedule through July here: http://www.facultyfocus.com/topic/seminars/
