.magnetic whiteboard for fridge.Of course, in the course of teaching, I also found that because of my own research and understanding of electronic whiteboards, it is still far from enough. Some phenomena in class still need to be improved. For example: 1. The use of whiteboards is rather monotonous, and the mining of whiteboard functions is not enough. In the classroom, I can often use a few functions such as switching, writing, image dragging, video, etc., which does not reflect the unique advantages of the whiteboard. And sometimes it feels too much to switch screens, it is difficult to leave a deep impression on the students' knowledge in the students' minds, and they will not achieve the desired teaching effect. 2. Lack of proper understanding of time when using. I think it's important to have a reasonable grasp of time when using an electronic whiteboard. Otherwise, it will make the children easy to visual fatigue, and the teaching of whiteboard will be fresh to boring. Usually, I will return to the organization, management and questioning methods of traditional classroom teaching, so that students can truly master the knowledge. But sometimes I still feel that the handling is not very good and needs to be strengthened. At the same time, with the electronic whiteboard, our preparation for the lesson has also increased. How to combine the use of the electronic whiteboard with the preparation of the lesson, and to really use it for the teacher, to reduce the burden is also a process that needs to be explored.
