The framework for a POGIL-PCL Experiment

We want the student goal in the Physical Chemistry lab to be learning how physical chemistry is done. Unfortunately, most students experience a laboratory where their goal is to replicate previously determined physical constants.

We have developed this cycle to describe the process of student activity in a POGIL-PCL experiment.

 
 
 

Basic Principles of a POGIL-PCL Experiment include the following:

Pre-experiment: students work in teams to

  • explore background information

  • consider experimental design

  •  predict an outcome

Experimental Protocols that

  •  provide broad instructions: e.g., exact masses or volumes omitted

  •  are repeated, often with minor variations: e.g., change the temperature, pH, concentration, or species

  •  may require use of shared data: e.g., use different form of magnesium

Thinking about the data: students work in teams to

  •  pool data to discern trends

  •  examine and apply models

  •  repeat procedure based on discussion

  •  develop concepts outlined in experiment objectives
