An interactive web-based program consisting of three integrated modules has been developed to enhance the understanding of the multidisciplinary nature and the complex principles of aerosol science and technology at the introductory level. Formative evaluation resulted in many suggestions from potential users on the improvement of the format and message. Feedback from students showed that the majority thought this mode of learning was effective, and they liked the dynamic animation and interactive features. Many also indicated that they prefer the modules be used to enhance rather than to replace in-class instruction. Summative evaluation based upon pre- and post-tests demonstrated that the website was effective for teaching the content. The results of the t-tests showed a statistically significant difference in the pre- and post-test scores. In summary, the evaluation data clearly indicate both the usefulness of the modules as teaching tools and a high degree of acceptance by students and faculty.
