They each have their own unique characteristics and possibilities -- some require more set up on the part of the presenter and all require audience members (or students) to have some type of mobile access. Despite the array of options that exist today, most college lectures remain static, passive experiences for students. Integrating a backchannel is far more complex than just learning a new tool. It introduces a dramatic power shift, flattening out the traditional hierarchy between presenter and audience member and weaving in the flow of otherwise silent ideas, reflections, and questions into the presenter's experiences. Like all effective online participation experiences, both presenter and participants require a new set of etiquette rules which can make or break the experience.
I was recently contacted by Nastasiya Koval from Amsterdam who shared a new (well, new to me) product with me called Shakespeak. It looks promising and there is evidence from use at Dutch Universities demonstrating increased exam results. What I like about it is that it extends options for participating in the backchannel via text, web, or Twitter. These options are nice, as they include students who have a feature phone (phone with text messaging) or smartphone (phone with internet) -- tools that all college students have today.
You can try Shakespeak out for free with up to 20 participants and then a premium account is necessary. Which to me, raises the question, how are institutions stepping up to support professor use of technologies like this one? Free tools are great but standardizing our students' experiences is an effective step towards eliminating their necessity to learn and use an array new tools.
Are you Using a Backchannel? Please Share Your Experiences.
If your college or university has a paid subscription to a tool that supports mobile backchannel participation, let me know! If you are experimenting with backchannels on your own, I'd love to hear how it's going and what tool(s) you use. Please leave a comment -- this topic will be included in a my forthcoming book and your voices are valuable!
