Contemporary instrumentation enables the enhancement of learning by allowing the merging of lecture and laboratory through rapid acquisition, analysis, and sharing of chemical data. This integrated format using contemporary instrumentation expedites analysis and creates more time for discovering, thinking, and learning. This format also provides the instructor with the flexibility to utilize laboratory inquiries to introduce or reinforce topics as appropriate. Student exposure to this integrated format is being phased into five different courses, four of which will employ HPLC. Currently, HPLC has been employed at the General Chemistry level for the introduction to and investigation of kinetics and equilibrium. Results and student feedback will be presented.
