A second study on computer-based training videos by Tan, Tan, and Wettasinghe
(2011) investigated video and self-reflection through blogs in a science pre-service professional
development program. Twenty-six teachers were asked to participate in research on the
effectiveness of computer-based training videos in teaching best practices to novice teachers.
Blogs were used to provide teachers an outlet to share and communicate with their peers for
enhanced collaboration. Results showed teachers perceived they gained new knowledge and
techniques for classroom instruction. Granted video was the main focal point for instruction,
but a second means of learning was included. Collaboration within the blogs was determined
highly effective in educating new teachers in best teaching practices.
