I have seen a version of this “smart dummy” technology, minus the VR component, in a training setting at the Center for Domestic Preparedness in Aniston, Alabama. The dummies are hooked up to computers that in turn measure learner’s performance against a set of desired ranges for different EMS interventions. By adding a VR component this platform enhances the alignment with constructivist characteristics such as social negotiation, collaboration, connectivity, active learning, authentic assessment, and learner control. The presentation mentions that the objectives are ill-defined because the application can create a limitless virtual environment, but once the learners choose their exercise, the program will have specific measurements and algorithms to measure success. Based on the video and program screen shots I would push back on the statement that the learners self-evaluate. It looks like the AR program, along with the smart dummy, measures and provides a pass/fail rating (checkmarks and x’s) by measuring the learner’s performance against a set of acceptable parameters. Based on this observation I consider the assessment authentic, but would not call it self-assessment.

This is a well-designed and informative presentation about the benefits of using HoloLens VR applications in a healthcare-focused, constructivist learning environment. Learners are able to participate in shared learning experiences with their instructors and peers, using a digital learning environment. They are also in a "safe space" where trial and error can occur without consequence or judgement. The learning experience touches on several constructivist learning theories, including situated cognition, experiential learning, and authentic learning. The choice of simulation activity (VR experience with low-fidelity simulator) is a perfect fit for a constructivist learning environment.
