We present an automated system that allows students to replay both audio and video from a large nonmajors' organic chemistry class as streaming RealMedia. Once established, this system requires no technical intervention and is virtually transparent to the instructor. This gives students access to online class review at any time. Assessment has shown that usage grew from about one-third of the class in the year the technology was introduced to about two-thirds of the class two years later. Almost all (93%) of students who reported using the technology rated it extremely useful or somewhat useful. An analysis of calculated grades reported by students reveals no overall course-grade benefit for students who reported that they found the technology useful over those who did not use it. Neither gender preference for usage nor gender-based benefits were found. (Contains 2 tables and 2 resources.)
