This study aims to develop effective VR-based teacher education simulation through formative evaluation. VR-based teacher education could be a tool to train strategies to handle challenging classroom situations. For this purpose, following three steps, we will validate the design and contents in the VR-based teacher education simulation. First, the scenario will be vilified by in-service teachers. Second, the simulation design will be revised based on the focused group interview. In the last step, we will collect the perception of users’ intention to use based on the TAM model questionnaire. Based on these three steps, the design and the content of the VR-based teacher education simulation could be validated.
