An augmented lecture feedback system to support learner and teacher communication

Abstract

In this paper it is advocated that the feedback loop between students and lecturer could be improved by making use of Augmented Reality (AR) techniques. The bidirectional communication teacher-students is sometimes hampered by students' fear of showing themselves up in front of their classmates. In order to overcome this problem a system is proposed whereby lecturers receive immediate and private feedback both individualised for each student as well as aggregated for the whole class. With that purpose the lecturer, who is equipped with a head mounted AR display, can visualize symbols that student select to represent their status in relation to the lecture content. In order to explore the possibilities of this approach an experience was conducted in a lecture on a university course. The results are encouraging and suggest that as this technology matures and less intrusive AR display models become available, it could provide effective support to communication and interaction during lectures.

Cues for Better Writing

“…Schulze (2003) described how computer-assisted language learning is a servomechanism that forms a loop between input and output. With Computer Assisted Language Learning, feedback can be immediate and a primary reinforcement type along with and even more immediate than grades, points, and scores (Zarraonandia, Aedo, Díaz, & Montero, 2013). According to Knight (2002), giving a student lowstakes feedback is more motivating than a high-stakes score.…”

Uses of Augmented Reality for Supporting Educational Presentations

“…Figure 1 depicts the architecture of the APFs system. This architecture has been derived from that used in the ALF system presented in [6] and is composed of two layers: the communication and the representation layer. The former supports the basic functionalities of a traditional Web based CCS system, providing listeners with the means to send feedback to the speaker.…”

“…An AR system could overcome this problem by allowing students to display graphical representations of their current state close to them, that only a teacher equipped with an AR device could visualize. Following these ideas in [6] we presented ALFs, an Augmented Lecture Feedback System for supporting communication during lectures. The system makes use of an optical see-through HMD to allow lecturers to visualize students' cues and notes on the presentation.…”

Immediate Feedback : A New Mechanism for Real Time Feedback on Classroom Teaching Practice

“…Augmentedrealityisamoderntechnologyusedinnextgenerationclassrooms.The term 'augmented reality' (AR) refers to the possibility of merging information with the real world by adding a range of useful overlays to the visual perception of the human. A study by Zarraonandia et al [1] which used this technology in the classroom to obtain continuous feedback from student to teacher employed a system composed of many components. Students used their mobile devices to interact with the system to provide feedback, and the lecturer wears AR Google glasses to see which student understands the concept by the interacting through Microsoft Kinect.…”

“…The feedback system using AR helps to overcome the problem of student reluctance when asking questions in front of their colleagues, and the students agreed on the improved communication and engagement with the educators. However, the system reported in [1]had many limitations which our new approach, and the system we have developed to implement it, address. The core features of an AR system include the educator being able to individually identify which student is understanding the material and vice versa.…”
