Students enjoy working with virtual worlds and this experience can be highly motivating. Reports of student enjoyment are common and several researchers and teachers report striking improvements in student motivation. Surprisingly, students are very tolerant of the low resolution and cumbersomeness of current HMDs. The main problem seems to lie in navigating around the worlds. Occurrences of simulator sickness symptoms are rare, and symptoms that do occur take the form of disorientation and ocular discomfort, and not nausea.
Teachers report their role in the classroom changing.
Instead of being a teacher with all the answers, teacher have found themselves acting as facilitators who support students in their discovery of worlds and in their building ideas based on information gained from those worlds. The use of pre-developed applications, however, can pose a problem for lesson administration and monitoring students' progress. In practical terms, desktop VR is more suitable for widespread use than immersive VR technology. Considering both the hardware and software requirements, desktop VR is quite a mature technology. It is affordable in that a basic level of technology can be achieved on most existing personal computers at either no cost or some minimal software cost.
