Two teaching experiments with Google Hangous on Air

I teach a class on the applications, implications and technology of the Internet and a major theme running through the course is the use of the Internet as a tool for collaboration. As such, we tried two teaching experiments using Google Hangouts on Air (GHoA).

(GHoA is a free video conferencing application for up to ten people. It differs from other video conferencing services in two ways -- an audience of unlimited size can watch the video conference while it is live and it is automatically recorded and stored on YouTube when it ends).

Student "office hours"

Our first experiment was having students who had done well on the midterm hold "office hours" online using GHoA. I did not participate in any of the sessions, but reviewed the videos afterward.

Students holding "office hours" online

Since I was not "present," the students were generally unguarded and light hearted, talking more freely than in class. Their discussion revealed a couple of content misconceptions, which I corrected the following week.

They also discussed the class itself. One group agreed that it was harder than they had expected and one group felt free to criticize the class. That gave me the opportunity to bring their criticism to the entire class, discuss the point they made and to give the most critical student extra credit for speaking his mind.

They talked about their study habits and how to do well in the class. In doing so, one group came up with the idea of using our weekly quizzes as a “study guide” and answer/discuss questions online. (I don't give them the answers).

They also got to see and hear themselves in an online conference and learned some practical things about microphone adjustment, camera location when using a phone or tablet, microphone positioning, speaker feedback, etc.

The sessions were not mandatory, but I gave those who participated extra credit for convening or attending a session. Many students chose not to participate and I polled them, asking why. Schedule conflicts at the time sessions were convened was the most frequently cited reason.

An online class meeting

The second experiment was to conduct a class session using GHoA instead of in the classroom. (We met at the usual class time, so schedule conflicts were not an issue).

I begin each week with a presentation of misconceptions I saw in their homework assignments and quiz answers from the previous week and current events relevant to our class. Since the goal of the class is to introduce the "skills and concepts needed for success as a student and after graduation as a professional and a citizen," that is followed by presentations focused on a couple of concepts and on a skill, for example, how to use GHoA, an image editor, etc.

I followed the usual in-class format during the GHoA session. The first nine students who "came" to the GHoA session joined the live video conference and those who logged in later joined the viewing "audience."

This was the first time I had run a GHoA class, and it was a learning experience for me. As shown below, I made a number of technical errors. It also felt strange to be presenting material without seeing the audience -- it made me appreciate radio announcers. I suspect one could get used to it.

Mistakes due to my inexperience

I also made the mistake of not preparing the students well enough. They only had one presentation and one assignment with GHoA before we ran our experiments.

After the session, I polled the students on their experience during the live hangout and their use of the recorded video. Here are the poll results for three of the questions on the live hangout:

Selected responses regarding the live class session

And two of the questions about their use of the recorded video after the session:

Selected responses regarding the session recording

As you see, they said they were more comfortable viewing the session at home than in class, their minds were less likely to wander and they generally thought it was as good or better than the classroom as a learning experience. The majority went back and watched at least a portion of the session recording, but there was an inconsistency in their reporting.

The last four questions asked about their overall preference and solicited comments. When asked whether they preferred meeting in class or meeting in a GHoA, 53% preferred the GHoA, 13% the classroom and 33% were indifferent. When I asked them in class what they thought was the best way to offer the course next semester, the consensus was that the first few meetings should be in the classroom and about half of the remaining meetings should be online.

(There were 19 questions in the entire questionnaire and you can see the full poll results (including their comments) here).

This was my first try at using GHoA and I made several mistakes which could be corrected. If others have used GHoA as a collaborative teaching tool, please share your experience.
