Synchronous and asynchronous video conferencing tools in an online-course:

The maturation of free ubiquitous video conferencing tools provides an opportunity for faculty members to experiment with alternatives to conventional asynchronous discussion forums commonly used in online courses. However, there continues to be debate about whether synchronous video conferencing has a meaningful role to play in an online course environment. Although the Community of Inquiry (CoI) framework’s influence in asynchronous discussion is well documented in the literature, it is less clear what role synchronous conferencing has in a Community of Inquiry (CoI). It is also unclear whether synchronous modes of inquiry provide worthwhile benefits for an online instructor. This study explores how the use of innovative video conferencing tools in an online course attends to the elements of the CoI.

In this mixed methods study, we observed weekly teacher and student inquiry by examining Google Hangout transcripts, Vialogues threaded discussions, and student reflective WordPress blog posts through the lens of CoI. The course used for this study was an online graduate course focused on the use of technology for teaching. We hypothesized that those students who participated in more synchronous conferencing sessions would perceive significantly higher levels of all three CoI elements and would engage in richer discourse supporting learning of the course content. We also analyzed student perceptions of the social, teaching, and cognitive presence through the CoI survey (Swan, 2008).

In order to examine the CoI related discourse, a corpus of text was utilized in this study which included Google Hangout transcripts, Vialogues threaded discussions, and student reflective WordPress blog posts. Text content analysis of this corpus represented a form of learning analytics. The text corpus was compiled and key themes were noted via qualitative constant-comparative analyses. The themes were analyzed using analytic induction to test hypotheses connecting discourse to CoI element. A form of text analytics was then applied to the text corpus in order to analyze the content of the student and teacher discourse.All text was compiled and analyzed using the Semantria (www.semantria.com) semantic linguistic program. Based on semantic algorithms from http://www.lexalytics.com/,All compiled text was analyzed for themes and sentiment. After compiling the linguistic components, statistical models were developed to compare discourse between synchronous and asynchronous environments and to predict the level of community of inquiry.

We used the Sloan Consortium’s Five Pillars to reflect on how the course’s interactive activities addressed quality. Learning effectiveness was demonstrated by increased opportunities for meaning making students had through discourse with each other and with the instructor. They were able to discuss courses readings in either a real-time Google Hangout or an asynchronous Vialogues threaded discussion. The use of freely available and ubiquitous tools makes it possible to scale the tools to multiple courses and programs. The tools provide access and flexibility for students who prefer face-to-face but need to take online courses because of work schedule or physical location. Faculty are satisfied to be able to provide options that address student discourse preferences. Finally, students report being satisfied with options to use synchronous conferencing for discussions which increases student voice.

Our presentation will share the results of our findings. Participants will learn how both synchronous and asynchronous video conferencing tools may be used for meaning making in an online course. We will engage the audience by web polling their preferences and promising practices pertaining to uses of synchronous technologies in primarily asynchronous online environments.

  1. Good one David. I would recommend, try using RHUB web conferencing appliances for conducting online trainings. You can have polling; raise hand, reporting, private chat room etc. and much more.

  2. Really!! It is a quite informative and expressive blog that gives a clear perception about using contemporary technology in online courses. Video conferencing, live chats and discussion on hangouts are absolutely contributing a lot to impart effective training online.
