The Level of Interactivity in a Virtual Reality Learning Environment: A Design Key Factor

Résumé

The increasing use of virtual laboratories (VL) based on virtual reality (VR) in the academic field [1] is associated with the need to constantly evaluate and improve the educational effectiveness of these educational tools [2]. Currently, there are different studies that clarify what factors must be considered when teachers design and implement this type of VLs in their classrooms. In this sense, equipping a VL with the appropriate level of interactivity has been revealed as a key factor to ensure that students learn better the concepts that they are studying and, in addition, they are able to retain them in their memory for longer [2]. This article describes and compares two versions of the same non-immersive VR-based VL that simulates a Rockwell hardness test and that were programmed with different levels of interactivity [3,4]. Although both VL versions guide the user through the virtual experiment, the first version offers few possibilities of interaction with the virtual environment, while the second VL requires a greater degree of interaction with the virtual elements to perform the experiment. The analysis carried out through the comparison between both VL versions can serve as a guide for teachers when deciding which level of interactivity is the most appropriate for the VL they are developing.Keywords: virtual reality learning environment, virtual laboratory, materials science and engineering, Rockwell hardness test, interactivity, education.References: [1] Vergara, D; Rubio, M.P.; Lorenzo, M.
