when was smartboard invented.The reason is that we think there are two main aspects. First of all, the training of the electronic whiteboard is not in place or the time is too short. The training content only covers the basic operations, and does not fully demonstrate the resource collection and integration functions, file storage and handout export functions of the electronic whiteboard. Second, the teacher does not have the environment to practice using the electronic whiteboard under the class. Any new media, we need enough time to get familiar with and master, as well as electronic whiteboards, such as the use of electronic sensor pens, only more attempts will be more handy. The electronic whiteboard needs the support of supporting software, and the software is generally installed only on the computer in the classroom , which indirectly affects the enthusiasm of the teacher to study the electronic whiteboard, thereby causing the teacher to be unskilled and affecting the teaching effect.
