| Abstract: | In spite of advances in physics pedagogy, the lecture is by far the most widely used format of instruction. We investigated students' understanding and perceptions of the content delivered during a physics lecture. Participants viewed a segment of a videotaped lecture on sound propagation by a well-known teacher. All of the participants were enrolled in a conceptual physics course and had previously covered the topic in class. Before viewing the lecture, the participants responded to a series of conceptual questions on sound. The participants then looked for answers to these questions in the videotaped lecture. On a written questionnaire, they indicated instances, if any, in which these questions were answered during the lecture. In addition to the students, a group of content experts (physics instructors) also participated in our study. We will discuss students' and experts' responses to the questionnaire. |
