In his large classes of introductory organic chemistry, Professor Montgomery records both the lectures and the evening open discussions (office hours). The following document provides student feedback on the presentation format (document camera vs. chalkboard), how the recordings impact attendance, how the students say they use the recordings, how frequently the recordings are used, and advice from students to other students on how to use the recordings effectively. Additionally the document summarizes the substantial benefit seen for select student groups, including students with disabilities, student-athletes, students who experienced family emergencies and medical issues during the term, and students with childcare responsibilities and inflexible work schedules. Feel free to contact Prof. Montgomery if you have questions about these teaching strategies.
