This document summarizes 15 studies on the impact of virtual learning environments on student learning. The studies examined topics such as virtual labs, online learning, and virtual software. The findings from the studies fell into three main groups: positive impacts on student engagement and learning, mixed impacts depending on implementation and subject matter, and no clear impacts. The conclusions also grouped into three areas: virtual learning can positively impact students when implemented well, the impacts depend on various factors, and more research is still needed. General recommendations included designing for interactivity and authentic experiences.
