Two challenges faced by university instructors in introductory chemistry courses are the need to keep the course material connected with technology that students are using as well as engaging students in a manner that keeps them interested in the subject. A case study is described where students in a general chemistry course were challenged to create and upload a video to the video-sharing Web site YouTube that could be used to learn solubility rules (which ions combine to form insoluble precipitates in dilute aqueous solutions). An assessment of the assignment was done by comparing results on a common exam question for courses with and without the assignment, as well as a follow up question on the final exam, survey questions, and comments. Results suggest that the solubility rules YouTube video assignment improved student learning of the rules and promoted interest in chemistry among a majority of the students involved in the activity.
