Abstract
Graz University of Technology has a long tradition in doing technology-enhanced courses. Following the latest trends, as mentioned in the NMC Horizon Report [32], we reviewed the possibility to use a wearable technology, in our case the Google GlassTM, in courses to improve the interaction between the lecturer and the audience with a special focus on huge classes. The lack of interaction in traditional face-to-face lectures is a well-known problem with a long research history [4], [12]. New technologies in Audience Response Systems (ARS) offer new ways to improve the interaction between teacher and student by enabling to ask questions to the audience [5] to get instant feedback during a lecture. Currently many types of web-based ARSs are available on the market [15]. Our research focused on finding an ARS suitable for the visualization in the Google Glass display. Further we developed a prototype and described first practical experiences.
Highlights
The lack of interaction in traditional face-to-face lectures is a well-known problem with a long research history [4], [12]
Further we describe the development environment and the view imposed by the display of Google Glass as we are interested in visualizing feedback results
We concentrated on technical aspects as well as possible potentials and limitations of Google Glass and Audience Response System (ARS) Backchannel carried out by a first field study
Summary
The lack of interaction in traditional face-to-face lectures is a well-known problem with a long research history [4], [12]. Universities often use lecturing as preferred teaching method because it is an economical and efficient method of conveying information to large groups of students. Systems like Audience Response Systems (ARSs) offer a proven way to interact with the audience during lectures Such systems allow the lecturer to get instant feedback from an audience. This paper discusses ARSs and the visualization of instant responses through Google Glass to the lecturer to enhance the interaction between students and lecturer. RQ1: How can Google Glass be used as part of an ARS to enhance the interaction between lecturer and audience in face-to-face lectures?. RQ3: How can Google Glass support the visualization of feedback and further improve the interaction between lecturer and audience in face-to-face lectures?
