A POGIL laboratory (http://www.pogil.org) is one in which students, in advance of any classroom work on underlying principles, work in teams to conduct experiments rather than exercises that verify previously taught principles. Prior to the beginning of any laboratory work the instructor poses a focus question (How is the structure of a molecule related to its boiling point? Do aryl halides behave like alkyl halides?) and students propose a set of tentative answers. To test these hypotheses, students run reactions and/or collect data, which are pooled and then analyzed with the aid of post-experiment or post-laboratory guided-inquiry questions. This learning cycle approach not only guides students to construct their own understanding of important chemical concepts but also helps them to develop valuable learning process skills. The application of the POGIL approach to courses in the first three years of the chemistry core curriculum will be described.
