Advantage 1: The intervention of information technology challenges the traditional teaching mode and brings a fresh air to the classroom. It enriches the way students perceive mathematical objects, and promotes them to be more willing to approach knowledge, better understand knowledge and achieve greater success in learning. The diversification of information collection, processing and transmission makes it easier for teachers to control the classroom and students' interest in learning will be improved.
Disadvantages: Teachers spend a lot of time preparing lessons, and it takes a lot of time from data collection, teaching mode design to multimedia courseware making. Especially in our rural middle schools, there is a shortage of teachers and a heavy academic burden. This contradiction is even more prominent.
