.best rite whiteboard.Classroom teaching is the life process of teachers and students. No matter how good the teacher is, the best standard course, because of facing different students, facing the living teaching process, using courseware animation and video to play will be lack of life and pale. The electronic whiteboard has a blackboard, and it has a selective and good interactive function with the blackboard, which provides a reliable helper for each teacher to attend classes independently. Show the purpose of the teaching and the experimental operation and principles on the whiteboard, and let the students exercise the necessary chemical terms on the blackboard. Strongly combined with the blackboard fully reflects the teaching effect of the whiteboard, so that the effect of classroom teaching is optimal, which is the main starting point of electronic whiteboard teaching. The whiteboard is dead, but the person who manipulates the whiteboard is alive. The ultimate purpose of the whiteboard is to serve the teachers and students. "My finger is a mouse", because on the whiteboard, you can directly click on various teaching software and courseware, and the whiteboard can integrate multiple multimedia technologies into one operating system. Therefore, the teacher does not have to be subject to the computer keyboard during class. Turn around the computer desk. In this way, more time is spent communicating with students, which helps to keep abreast of the current learning situation of students. More useful is to avoid the occurrence of embarrassing situations. For example, in the classroom, when one of the super-chains in the courseware fails due to a mistake in the preparation, the user clicks on the whiteboard a few times, and the relevant content is hanged without changing the display of the entire whiteboard screen. Thus a good "masking" of the mistakes.
