It is daily classroom teaching. A powerful tool for informationization. In the interactive whiteboard environment, the role of the teacher and the organization of the resources have changed. How to effectively apply interactive whiteboard to all levels, disciplines, and types of classroom teaching through instructional design will be the focus of future research work.. The IQAio GR519 is an upgraded lightweight version based on the original IQAio GR511. The original dual-cavity structure was changed to a bottom-edge structure, so that the minimalist design accommodates modern classrooms and conference rooms. With one IQProjector V2 and one IQView E3821, you can achieve flexible and intelligent classroom.
