Adopting POGIL Methodology for Analytical Chemistry
POGIL (Process Oriented Guided Inquiry Learning) is a NSF sponsored project designed to actively engage students in the learning process in the classroom. Ana-POGIL activities cover topics ranging from statistics to equilibria and to instrumentation. Materials are intended to have students work in groups on activities; each activity is structured in such a way that each concept is divided into a series of leading questions that allow the team to work through the concept. Answer keys can be re
