POGIL (Process-Oriented Guided Inquiry Learning) and SWH (Science Writing Heuristic) are two complementary approaches to laboratory work that follow a three-stage learning cycle and involve active learning and guided inquiry. In response to a question posed by the instructor (POGIL) or questions developed by the students (SWH), students work in teams to gather data from experiments run under a variety of conditions. They examine the pooled data from which they construct theories and make claims that can be backed up by the experimental results. Group discussions, reflective writing, and in some cases additional experiments are used to further develop the concepts. Participants in this workshop will examine model experiments, work with student-generated data in a simulated laboratory setting, and convert existing and currently used lab activities to POGIL or SWH experiments. Workshop participants should bring copies of two of their lab activities for conversion to POGIL or SWH experiments.
