Presentation tools are increasing in popularity and providing powerful tools for creation of instructional materials and accessible information in audio-visual formats. When used appropriately, these tools can support and extend traditional presentations in valuable ways. In lecture settings, Microsoft PowerPoint, for example, has become the dominant presentation tool because it is both readily available and easy-to-use by instructors (Grabe & Grabe 2007). It allows instructors to create and manipulate presentations in a wide variety of contexts that can enhance students’ interests and engagement (Mills & Roblyer, 2006).Presentation tools help instructors clearly identify the main points of a topic or activity while still providing the details through presentation (Loisel & Galer, 2004). Instructors can incorporate multiple types of media formats (e.g., diagram, photo, drawing, sound, animation, video, etc.) that cannot be easily integrated together into one single medium. Learners are also attracted to presentation applications because of graphical, transactional, aesthetic and interactive features they provide. Parette, Blum, Boeckmann & Watts (2009) suggested that regardless of such concerns and problems related to the use of presentation tools, like PowerPoint, it is no longer an issue of whether to use them or not. Instead, instructors must focus on how they can successfully use them inside and outside classrooms to support learners (Parette et al., 2009)
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 pres...
