Abstract
In this study, a new multimedia learning tool for physical chemistry was implemented in a class setting, and students’ attitudes and learning gains examined. The Physical Chemistry in Practice (PCIP) DVD contains multimedia modules that provide an in-depth description of the research of eight different scientists. Each module contains a documentary style video program of the researcher and their laboratory, HTML-based background information about the topic, problems for students to work on, and links to related information. The DVD was implemented in a physical chemistry laboratory course where students worked through a module on surface- enhanced Raman spectroscopy (SERS). Data was collected in the form of pre- and post-tests of content knowledge and surveys about attitudes and academic career choices. Students showed statistically significant learning gains after using the DVD and showed an increase in their recognition of the applications of physical chemistry to real problems. Students also showed an increased interest in further study of physical chemistry. [Chem. Educ. Res. Pract., 2007, 8 (3), 308- 326.]
