Speaker Bio

Alban Delamarre is a Ph.D. candidate in the School of Computing and Information Sciences at Florida International University VISAGE research laboratory under the supervision of associate professor Christine Lisetti. Alban received an Engineering Diploma and a M.Sc. in Computer Science from the National School of Engineering of Brest, in France, prior to joining FIU. Alban’s research focuses on using virtual reality and virtual social agents to support education and nature conservation.

Description

Teachers who are equipped with the skills to manage and prevent disruptive behaviors increase their students’ potential to achieve academically and socially. Student success increases when prevention strategies and effective classroom behavior management (CBM) are implemented in the classroom. However, teachers with less than five years of experience, early career teachers (ECTs), are often ill equipped to handle disruptive students. ECTs describe disruptive behaviors as a major factor for stress given their limited training in CBM. As a result, disruptive behaviors are reported by ECTs as one of the main reasons for leaving the field.

Virtual training environments (VTEs) combined with advances in virtual social agents can support the training of CBM. Although some VTEs for teachers have started to be built, requirements to guide future research and development of similar training systems have not been defined. We propose a set of six requirements for VTEs for teachers. Our requirements were established from a survey of the literature and from iterative lifecycle activities to build our own VTE for teachers. We present different evaluations of our VTE using methodologies and metrics we developed to assess whether all requirements were met. Our VTE simulates interactions with virtual animated students based on real classroom situations to help ECTs practice their CBM.

We enhanced our classroom simulator to further explore two aspects of our requirements: interaction devices and emotional virtual agents. Interactions devices were explored by comparing the effect of immersive technologies on aspects of users’ experience (UX) such as presence, co-presence, engagement and believability. We adapted our VTE originally built for desktop computers, to be compatible with two immersive VR platforms. Results show that our VTE generates high levels of UX across all VR platforms. Furthermore, we enhanced our virtual students to display emotions using facial expressions as current studies do not address whether emotional virtual agents provide the same level of UX across different VR platforms. We assessed the effects of VR platforms and display of emotions on several aspects of UX. Our analysis shows that facial expressions have greater impact when using a desktop computer. We propose future work on immersive VTEs using emotional virtual agents.
