The NSF-funded POGIL-PCL project implements the principles of Process Oriented Guided Inquiry Learning (POGIL) to improve student learning in the physical chemistry laboratory (PCL) course. We describe in detail two of the POGIL-PCL experiments that have been reviewed and tested at a variety of institutions. The first, “How does the composition of a mixture affect its melting point?,” is a re-invention of the traditional solid-mixtures phase diagram experiment using fatty acids. The second, “Which apple would be best for fruit salad?,” probes the enzyme catalyzed oxidation of catechol using enzyme extracted from apples. In each experiment students follow two learning cycles and work as a class to make predictions, select the appropriate parameters to vary or compare, carry out a general protocol, and analyze their results. We will present typical student results and discussion for these experiments. The authors gratefully acknowledge the support of the NSF (DUE 1044624).

The NSF-funded POGIL-PCL project implements the principles of Process Oriented Guided Inquiry Learning (POGIL) in order to improve student learning in the physical chemistry laboratory (PCL) course. POGIL principles have been used to develop inquiry-based physical chemistry experiments that emphasize modeling of both macroscopic and molecular chemical phenomena. Project results include physical chemistry experiments in areas such as chemical kinetics, phase transition behavior, equilibrium thermodynamics, spectroscopy, and computational chemistry. We have also employed workshops to build a community of instructors who are currently working together to develop, review, refine, beta-test and implement experiments in a variety of undergraduate environments. In this presentation, we describe the general structure of a POGIL physical chemistry experiment and give an overview of experiment development and implementation. We also discuss ways in which interested physical chemistry laboratory instructors can become involved in the POGIL-PCL project.
