The present research investigates the effectiveness of a teaching approach using a Mixed Reality (MR) learning environment to address students’ alternative ideas about the properties of gases and the thermal effects of their expansion and contraction. The research was conducted in the context of the academic course of Chemistry. The sample consisted of 32 student teacher candidates in their final year of study and the mixed research method was followed to collect the research data. The students, with the help of appropriately structured scenarios and worksheets, carried out hands-on activities and investigated the molecular composition of different types of gases and the evolution of the expansion and contraction phenomenon in the microscopic level using the Microsoft HoloLens 2 device. The research findings demonstrated that students achieved a deeper comprehension of the studied concepts by actively engaging and receiving prompt feedback in the Mixed Reality environment. This environment was regarded as a user-friendly tool with high educational value that notably enhances learners’ interest and reinforces their engagement in the educational process.

摘要

The present research investigates the effectiveness of a teaching approach using a Mixed Reality (MR) learning environment to address students’ alternative ideas about the properties of gases and the thermal effects of their expansion and contraction. The research was conducted in the context of the academic course of Chemistry. The sample consisted of 32 student teacher candidates in their final year of study and the mixed research method was followed to collect the research data. The students, with the help of appropriately structured scenarios and worksheets, carried out hands-on activities and investigated the molecular composition of different types of gases and the evolution of the expansion and contraction phenomenon in the microscopic level using the Microsoft HoloLens 2 device. The research findings demonstrated that students achieved a deeper comprehension of the studied concepts by actively engaging and receiving prompt feedback in the Mixed Reality environment. This environment was regarded as a user-friendly tool with high educational value that notably enhances learners’ interest and reinforces their engagement in the educational process.
