Interactive electronic whiteboard combines the advantages of ordinary blackboard and modern multimedia teaching. With the development of social science and technology, multimedia technology has entered the classroom. The multimedia courseware used in traditional teaching can only be presented in advance. Teachers lecture completely around the same courseware, making the classroom a preset performance, which is difficult to adjust in time according to the actual situation of students' learning, and lacks the most wonderful "improvisation" in classroom teaching. Therefore, as a new generation of interactive electronic whiteboard, it is welcomed by teachers and students with unparalleled advantages. It not only inherits the advantages of ordinary blackboard as a teaching method, but also integrates the advantages of modern multimedia teaching, and its special technology can just meet the development needs of classroom teaching. The application and popularization of interactive electronic whiteboard in classroom teaching has optimized teaching methods, created vivid teaching environment, created lively interactive atmosphere, fully mobilized students' learning enthusiasm, stimulated students' interest in learning and stimulated students' intelligence, thus improving classroom teaching efficiency, especially in interactive learning, cooperative learning and heuristic learning.
