As we fi nd further applications of Virtual Reality (VR) in the field of education, a need to understand the core facilities of a virtual experience becomes vital. Few have studied the impact of interaction techniques on problem solving. In this thesis, we study the effect two egocentric, interaction techniques (virtual hand, raycast pointer) have on problem solving, recognition, and timing, all core learning outcomes. Additionally, we observe how these outcomes vary in relationship to the type of user-performed task (selecting, sorting). We describe a study in which participants (N = 107) are presented 30 questions that challenge their ability to alphabetically order English words. Questions are presented as interactive interfaces in a Virtual Environment (VE) and participants answer these questions using the interaction technique they've been assigned. Performance variables were recorded in addition to testing participants for their ability to recognize words that have already appeared. Results point to both interaction technique and the type of user-performed task as having statistically signi cant e ects on performance, recognition, and timing.
