Second, teachers don't understand the general tools, subject tools and subject resources of electronic whiteboard, and can't fully understand the advantages of electronic whiteboard. Even if I use an electronic whiteboard, the effect is not as good as that, so I naturally don't want to use it.
Third, the electronic whiteboard hardware is unstable. Due to the poor quality stability of electronic whiteboard, problems often occur in the process of use. For example, the whiteboard is disconnected and cannot be used, and the whiteboard cursor cannot be operated, so it is often necessary to restart the program.
Fourth, the computer performance is not good. If you want to use an electronic whiteboard, you need to use a computer. The use of equipment is relatively complicated. The combination of electronic whiteboard and computer configuration is a system. If one of the devices (computer, whiteboard, projector, etc.) has hardware or software problems. ) will cause trouble to the teachers who use it. Relatively speaking, it is simple and practical to use the physical display platform without a computer. As long as the projector and the display platform are turned on, the teacher can project the physical object or make comments and exercises.
Five, the electronic whiteboard equipment is expensive. The quality of electronic whiteboard is unstable, and resources and tools are insufficient; The electronic whiteboard needs to be used with the projector, and the light bulb of the projector needs to be replaced after a period of use, which is very expensive. If the school argues that it is unnecessary, it is unnecessary, and teachers don't need it at all.
Sixth, the operation of electronic whiteboard is more complicated, which is not as good as the traditional blackboard and can be used by teachers. To master the application of electronic whiteboard in the classroom, teachers need to spend a lot of energy and time to learn and master the application of electronic whiteboard.
Seven, the common tools of electronic whiteboard, such as clock, hood, spotlight, etc. It is fresh for teachers and students who are new to the electronic whiteboard, but it loses its attraction and is of little use after a long time. However, the theme resources of electronic whiteboard are generally less, which may be due to the mutual anti-piracy of various brands of electronic whiteboard, and the enthusiasm of electronic whiteboard merchants to develop resources is not high. This also directly affects the use value of electronic whiteboard.
Eight, the electronic whiteboard is just a tool (some people say that the electronic whiteboard is a platform). In order to give full play to its role, teachers need to integrate it with third-party software. Many teachers have not reached the level of seamless integration. The integration ability of electronic whiteboard and third-party software is related to the teacher's personal information technology level, and it also needs to spend some energy on learning. More importantly, it needs to be used frequently in classroom teaching to accumulate experience.
Nine, although the electronic whiteboard liberates teachers from the shackles of computers, teachers can only operate in front of the electronic whiteboard, which has great restrictions on teachers' behavior and activity space. I look forward to one day, electronic whiteboard, mobile tablet computer, voting device and so on will be used together through the network. However, it is understood that this is still in the experimental stage in China and has not entered the normal application of the classroom.
The above factors will affect the use effect of electronic whiteboard in the classroom, and will also affect the enthusiasm of teachers to use electronic whiteboard. "If a worker wants to do a good job, he must sharpen his tools first." The electronic whiteboard should be used normally, and the hardware of the computer and the electronic whiteboard should be configured reasonably and maintained frequently to ensure the normal operation of the equipment. The technical level of teachers' electronic whiteboard and the combination of electronics and other software are the key to improve the application of electronic whiteboard, and it is also very important to strengthen teacher training. The normal application of electronic whiteboard is impossible unless there is external pressure. Teachers must see the advantages of electronic whiteboard and taste the sweetness of applying electronic whiteboard, so that teachers will have internal motivation.
