This Innovative Practice Full Paper presents findings from the implementation of a virtual reality-based learning module. In the Fall of 2020, a prototype for a novel intervention namely, Virtual/Augmented-Reality-Based Discipline Exploration Rotations (VADERs), was offered as part of the first-year Introduction to Architectural Engineering (AE) classes at two universities. VADERs will ultimately be a collection of modules that are designed to improve student engagement and diversity-awareness by providing interactive virtual explorations of an engineering discipline and its sub-disciplines. VADERs utilize an open source, device-agnostic, and browser-based three-dimensional Virtual Reality (VR) platform, creating unique accessibility, synchronous social affordances, and media asset flexibility. The conjecture explored in this paper is: Having first-year engineering students experience Architectural Engineering and its sub-disciplines through an interactive VADER module, will improve their self-efficacy in regards to their commitment to studying the discipline. A total of 89 students participated in the VADER pilot in Fall 2020. Complete data was collected from 67 of these participants in the form of pre- and post-surveys, and final project deliverables. Results tied to the hypothesis and recommendations for future related work are discussed.
