Abstract
Virtual reality (VR) enables the creation of immersive and interactive learning environments for students and teachers. This article reports on an exploratory teaching practice conducted with pre-service secondary school teachers using Neotrie, a dynamic geometry software in virtual reality. In small groups, future teachers must learn how to use the software and design a didactic sequence to bring to the classroom. Following a research-action methodology, through this experience it is reported both the advantages and difficulties encountered when starting to use VR to design didactic sequences, as well as when learning a VR sandbox software with interactive tools, like Neotrie. A proposal for assessing the sequences under the premises of the TPaCK model is also included.
