Virtual reality is a frequently used tool in vocational training. Nevertheless, its efficiency has not been systematically tested. The main goal of this study is to assess the effectiveness of a virtual environment (VE) for learning a complex procedure in the biomedical domain. Two experiments were performed. The first one assessed internal validity of the VE, which is the effectiveness of using a VE in the process of learning a new procedure. The second one tested external validity of the VE, which is the participants’ ability to reproduce the acquired skills in a real context. We find that internal and external validity must be evaluated before using a virtual environment in long-term procedure learning. The results of such evaluations are a basis for future experiments aiming to optimize learning conditions in a VE and transferring the acquired skills in a real context.
