Recently, webinar (web seminar) tools (e.g., Elluminate, Adobe Acrobat Connect, Live Meeting) have been attracting more and more attention with the advancement of online learning technologies because webinar tools facilitate real-time communication and enrich the interactivity in an online learning environment. Corporations have long adopted webinar tools for real-time meetings; however, we need research-based data to understand how webinar tools can be successfully integrated into an online learning environment. To strengthen our understanding of appropriate webinar training and teaching strategies, this qualitative study investigates the perceptions of student-trainers who use webinar tools. The results show that student-trainers are satisfied with their webinar-facilitated delivery of conceptual knowledge. Webinar provides a nearly face-to-face environment that increases participants' social presence and facilitates multi-level interaction. This paper presents suggestions regarding webinar-session implementation strategies.
