BACKGROUND: The Respiratory Care Department of The University of Texas Medical Branch, at Galveston has been providing their students with digital video recordings of lectures accessed through Black Board for the past three years. The current study compares the use of the conventional video recordings to a second group of students using computer based Tegrity Power Point recordings.METHODS: Lectures were recorded in the classroom using a conventional video camera with a lapel blue tooth audio transceiver. The digital video was subsequently compressed using Sorenson Squeeze software and then posted to blackboard within 48 hours. Computer based Tegrity PowerPoint lectures were recorded by using a desktop computer webcam. These lectures were uploaded within 24 hours of completion. We compared the surveys collected from two groups of students: 75 RC students with access to live videos, and 50 Clinical Laboratory students with access to Tegrity recordings. Survey questionnaires were completed anonymously and had no other student identifiers. The questionnaire was divided into two parts: (1) outcome and (2) technology. RESULTS: (1) Outcome: The majority of students in both groups - Tegrity (98%) and Conventional Video (82%) thought that the recordings were an effective Instructional Tool. Of the Tegrity group 94% would recommend lecture videos to future students compared to 82% using conventional video. (2) Technology: 89% of the Tegrity students did not encountered any problems in accessing the lectures from blackboard compared to 86% for students accessing conventional video. The Survey also indicated that the conventional video quality was better when compared to the Tegrity recordings (86% vs 74%). CONCLUSION: Our study indicates that students believe videotaped classroom lectures using either technology are a valuable educational tool. The study also shows that a higher percentage of students think that the video quality is acceptable when using conventional video recordings vs. Tegrity recordings. Sponsored Research - None
