摘要: Collaborative learning has been shown to be beneficial for children's performance, increasing the curiosity and intensity of ability cooperation. Mixed-Reality with collaborative is trending research topic in Human-Computer Interaction (HCI) area. Additionally, rise attention global warming which brings more extreme weather climate conditions, earth science education would one crucial topics next generation. Moreover, there are few augmented reality mixed applications on subject. In this paper, we propose a Mixed Reality Tornado Simulator offers an setting. Students instructor can cooperate knowledge formation its damage cause human-built structures, farming, vegetation by using our application Microsoft HoloLens. Also, evaluating performance setting, study cognitive load while student abstract Earth Science. We will separate into control group experimental groups use different teaching instruments test difference load.
