Evaluating the Effectiveness of Enhancing Webcasts With Digital Tagging

Abstract

Background: Webcast platforms have paved the way for flipped classroom formats and distance learning, possibly replacing traditional forms of curriculum delivery. However, studies have shown that webcasts still have room for improvement for functionality and usability. In this paper, we introduce the SAM (Stand Alone Media) network platform, which provides features such as embedded digital tags as well as chapter-based and keyword-based navigation that improves the overall usefulness of webcasts.

Methods: A webcast video provided by the Department of Anatomy was uploaded to two webcast platforms: the MedSpace platform, which is currently in use in universities such as the National University of Singapore, and the novel webcast platform, the SAM Network. Students were recruited to appraise the usefulness and efficacy of both platforms.

Results: Most students had issues with the audiovisual quality in current webcasts. The SAM platform was able to address issues students encountered on MedSpace, such as the ability to navigate through the video via keywords. Students also found the digital tags useful. Both platforms proved to be effective in helping students gain more knowledge of the curriculum content.

Conclusion: Webcasts are useful and effective tools in delivering curriculum content. However, issues with webcast quality and platforms can hinder students’ learning. The SAM network can address many of these issues, proving the SAM Network’s efficacy as a webcast platform. Ultimately, for webcasts to achieve maximum perceived usefulness among students, much would need to be improved upon not only in the webcast platforms we use, but also in changing institutional norms towards learning.
