Exploring the Effectiveness of Face-to-face Mixed Reality for Teaching with Chalktalk
This addresses the need for improved interactive teaching tools for educators and students, though it appears incremental as it builds on existing Chalktalk software.
The researchers tackled the problem of dynamic content in teaching by developing a Mixed Reality platform that integrates Chalktalk for face-to-face interactions, comparing it to projected Chalktalk to assess learning, retention, and engagement.
Teaching that uses projected presentation media such as slide-shows lacks support for dynamic content whose form and behaviors require live changes during a lecture. Recent software alternatives such as the Chalktalk software platform allow the creation of interactive simulations in arbitrary sequences and combinations within presentations. These more dynamic solutions, however, do not optimize for face-to-face interactions: eye-contact, gaze direction, and concurrent awareness of another person's movements together with the presented content. To explore the extent to which these face-to-face interactions may improve learning and engagement during a lecture, we propose a Mixed Reality (MR) platform that places Chalktalk's behaviors and simulations within a mirrored virtual world environment designed for face-to-face, one-on-one interactions. We compare our system with projected Chalktalk to evaluate its relative effectiveness for learning, retention, and level of engagement.
