As part of my teaching experience at Towson University I was instrumental in introducing computer-assisted discovery-based instruction modules into the General and Organic Chemistry courses. This work was funded by a major 4-year K-16 grant from the NSF-VIP program. In General Chemistry I worked to introduce modular, hand-held universal measurement instruments that allowed for data collection from various probes (temperature, pressure, electrode, etc.). This enabled students to collect a far larger data set per experiment and also engage in fairly sophisticated computerized data analysis. In Organic Chemistry instruction I introduced a set of experiments that allowed students to acquire GC, GC/MS and FT-IR data of unknown reaction products and analyze it using database searches. This enabled students to gain a better understanding of practical aspects of preparative organic reactions. Analysis of the structure of by-products aided in far better grasp of the reaction mechanisms. I have taught physical chemistry at Towson and inorganic chemistry at Brown. My involvement in computer-aided instruction goes back to my time as Teaching Assistant at Brown, and I’ve expended significant effort to obtain external and internal grants to provide students with a realistic, modern lab experience.
