where is whiteboard in teams.In the past, during the course of using the courseware, the teacher had to go to the main console to operate the computer and mechanically display the courseware content to the students. The teaching process was not smooth, and the students often could not actively participate in the teacher's elaborate design as expected. In the activity chain, classroom teaching seems to have lost the source of vitality. In the process of teaching with the interactive whiteboard, the teacher only needs to click the required tools or icons on the whiteboard to achieve the required operations, and the interactive whiteboard's own interface provides the teacher with a blank area of ??the writing pad. Teachers can use the blackboard as a teacher, and follow the teacher's lecture habits, making the lectures very comfortable. Because the interactive whiteboard system is compatible with various softwares, its own resource library contains pictures, flipcharts, audio-visual materials, and subject tools of various subjects, so teachers can refer to the required information flexibly and conveniently. Resources and teaching software have greatly enriched teaching information.
