Virtual learning environments (VLEs) were introduced to progress students from passive to active learners. Active learning promotes the critical thinking skills essential for the transfer/use of classroom-acquired knowledge into the clinical setting. A VLE forms an increasingly vital component of clinical skills development in a range of disciplines.A randomized control trial was conducted with students randomly attending one of two teaching sessions about radiation therapy. Both sessions were identical except a VLE was used in the second talk with the first being solely didactic. Anonymous questionnaires were distributed. Two weeks after the talks, participants were required to complete the same knowledge questionnaire to determine retention. Mann-Whitney, means, standard deviations, and chi-squared tests were used according to data characteristics. Qualitative data (open-ended questions) were analysed thematically.Virtual learning seemed to significantly improve students' satisfaction/engagement and recall. A total of 40 students attended the teaching sessions. The student group taught using the VLE had higher mean scores for retention than the didactic group; however, this was not statistically significant. Use of VLEs was associated with greater satisfaction/engagement than didactic information (P = .003). Students' learning styles seemed to have no effect on their satisfaction/engagement and ease of learning. Three key themes emerged from the qualitative data: (1) the visuals were good/helpful, (2) the talk was informative, and (3) more details/visuals were required.The key findings from this study suggest that there is a role for VLEs in the teaching of students. There is a need for the introduction of advanced technology into health care education as virtual reality, such as Virtual Environment of Radiotherapy, has shown improvement in students' satisfaction, engagement, and recall. Whether VLEs qualify students better than conventional didactic teaching is still undetermined, but these first results are encouraging.
