digital whiteboard wiki. As we all know, the reason why the electronic whiteboard is called the whiteboard is because it is the combination of the blackboard and the multimedia computer. He first inherited not only the fine traditions of the blackboard, but also the advantages of multimedia, especially in terms of cooperative teaching and independent learning. Teachers can click on the tools and icons they need on the whiteboard floor to realize their own operations in the blank area of ??the whiteboard. At this time, the whiteboard is like a blackboard, which conforms to the teacher's lecture habits and makes the lectures very comfortable. In addition, the passive sensor pen of the whiteboard is like a dust-free chalk, which enables teachers and students to freely write, drag and draw on the whiteboard and courseware. This dust-free pen can make students watch and listen. Write and do whatever you want. It eliminates the dullness of traditional courseware and the pollution of dust, and also enhances the interaction and cooperation between teachers and students. For example, in the sentence conversion of English class, the teacher can let the students operate on the whiteboard first, and then explain it. Whether it is a student operation or a teacher explanation, they can use this "pen" to operate while watching the students. The process of transforming the entire sentence in the process of listening to the explanation is clear at a glance, making the abstract thinking visual. Because students have more opportunities to display, perform, practice, and cooperate in front of the whiteboard, the enthusiasm for participation has also increased, making the classroom more dynamic..
