The topic of “Lecture Capture” is frequently in the news with discussions and debates on benefits, costs, educational outcomes and technology. There is some confusion, though, about what video in the classroom means and there are really multiple uses for this technology. The types of videos created and the purposes for which they are used can vary substantially, and it’s a mistake to throw all classroom video into one bucket called “lecture capture”. Here is our take on this topic:
Lecture Capture is the recording of the daily lectures in a documentary fashion and the posting of those videos on a website or learning management system for student review. The instructor walks into a classroom and presses the Record-Start button, talks for 50 minutes, presses the Record-Stop button and walks out. By the time the instructor returns to their office the lecture has been automatically posted on-line and is available to the students.
Lecture Creation is used to prepare short, 3-10 minute videos on single topics for use in MOOCs or flipped classrooms. The students are given the assignment to view the videos on their own and further discussion of the contents of the video is left for the classroom, usually in an interactive or problem solving environment.
Performance Capture is used where the subject of the recording is the student instead of the instructor. The student is given some assignment or task, the activity or event is recorded, and later an assessment is done by reviewing the video with the instructor. We see this frequently in activities such as medical training simulations and exercises, mock trials for lawyers, behavior therapy counseling sessions and business school student presentations.
Event Capture is a general category where recording equipment is used to capture special events on campus such as graduation speeches, presentations by visiting scholars and Nobel laureates and other meetings of interest. The videos are frequently post-produced by professional video editors and often highlights are extracted for other purposes such as marketing or news.
In all of the above cases the availability of video online enhances the educational experience and promotes dispersion of knowledge in that educational community (and maybe even to the world at large).
