This paper
describes the technology and methodology used in the development and usability evaluation
of a network, named PresentationTube, to help faculty members at Sultan Qaboos
University, Sultanate of Oman, produce and share quality video presentations
for their students. The network offers a desktop application for recording
video presentations and an online platform to share presentations online. The
recorder allows faculty members to narrate and annotate PowerPoint slides and
synchronize a variety of visual aids, including webcam footage, whiteboard,
drawing board, and web browser. The platform uses YouTube API to upload and
integrate videos with scrollable slide thumbnails. Quantitative and qualitative
techniques including, quality of video presentation rubric, usability questionnaire,
instructors’ interview and students’ perspectives to video presentations
questionnaire were implemented to collect data and report on the usability of
the network and effectiveness of video presentations. The results of usability
evaluation showed that the network was perceived by instructors (n=31) and
students (n=218) as effective, efficient, and relevance for self- production
and sharing of video presentations. In addition, video presentations (n=187)
produced by participants met the criteria of quality of video presentations. Directions
for future research and system development are suggested in this study (Sadik, 2014).
