Adams, S. and Duvall, B. (2014) Designing, building and supporting online lab courses, University Business, February 4
This article is a summary of a presentation made at the University Business conference last June. It describes how two biology professors at the University of South Carolina, Roger Sawyer and Robert Ogilvie, developed an online course on histology that was built around students being able to drill down into images of the cell at various levels through the use of a large repository of digitized slides of cells, accompanied by a voice over narrative:
Using Adobe Presenter to create the slides and WebMic to record the audio, Sawyer and Ogilvie built lectures, grouped slides together and developed quizzes. The program offered the flexibility for faculty to record and post content right from their desktops. With each set of slides, students can move ‘bit by bit,’ drilling deep down into a cell, reading the accompanying information, and listening to a narrative as they go. Since the self-paced content requires large files, it is hosted offline via Screencast (by TechSmith).
This was partly driven by space limitations in USC’s physical labs, and partly by increasing demand for students with health sciences qualifications. This approach has enabled the course to jump from 70 enrollments a year to 350. At the same time, student performance for the online students is the same as for the on-campus students, and over 90% of students rate the course highly on a number of variables.
One reason for the success of this approach is that the two professors worked closely with instructional designers and the university’s media services department. The team developed their own tool for recording audio over the slides (webMic), using ‘off-the-shelf’ apps, rather than programming from scratch.
There is a video recording of the presentation available here, which is worth watching because as well as describing the histology project, it also looks how online learning is being integrated into physical labs at USC, and the impact on room design. In other words, students and faculty need online access not only from home and office, but also while in the lab.
