Molecular Level Laboratory Experiment: Chemical Equilibrium

Integration of Flash with Digital Video: Interactive Problem Solving

My 2001 - 2002 HHMI Undergraduate Education Program Faculty Award consisted of two parts: the development of a Molecular Level Simulation of an Equilibrium Reaction and the development of Flash/digital video interactive problems. The molecular Level Simulation of an equilibrium reaction is moving along very nicely.

Current version of the equilibrium simulation

The simulation was used during the Spring 2002 in three PreLecture Explorations. A PLE is an activity student do prior to lecture. The activity consists of between 4 and 10 questions centered around a particular concept. Generally students have not discussed the particular ideas covered in the PLE. The responses to the questions are recorded and saved for my review before lecture. I can determine misconceptions and overall understanding of the concept(s) covered in the PLE from the student responses. Additionally students can ask questions and indicate where their understanding is weak. From these comments and questions I can focus attention during the lecture.
