RESEARCH ON MIXED REALITY TECHNOLOGY IN ATOMIC FORCE MICROSCOPY EXPERIMENT TEACHING

To explore how to effectively apply mixed reality technology to physical experimental teaching, this study designed and applied scales for measuring cognitive load, immersion, emotions, student attitudes, and knowledge acquisition questionnaires. By using the HoloLens2 device, a mixed reality (MR) system for the installation process of atomic force microscope (AFM) probes was implemented. It was applied to real experiments teaching and the data was collected from participating students. The research results show that students have a positive learning attitude, experience a deep immersive experience, achieve a high level of knowledge mastery, and generally do not feel a significant cognitive load when using the mixed reality system for the installation of AFM probes. However, the results also show that in the process of visualizing physical quantities, MR experimental form may bring some cognitive misunderstandings to students, particularly in the visualization of physical quantities. Additionally, students in the dimension of immersion control performed not so good, indicating that some students believe they have certain difficulties in controlling MR devices.
