In our society, science and technology can be said to be a very important link, because progress in any field is inseparable from the promotion of science and technology, and so is education. The development of science and technology makes our educational methods more and more convenient, and also enables children to acquire knowledge through various channels. Compared with the single teaching method in the past, it can be said that there have been great changes, which is precisely the convenience brought by science and technology. What impressed me most was that the teaching environment when I was a child was nothing more than teachers, blackboards, chalk and a class. However, when I was in high school, I was exposed to multimedia, which was very novel. The efficiency of the teacher's class was really high. Compared with the previous hierarchical teaching, I will briefly talk about this article. In the process of education, I feel the changes brought by technology.

First, multimedia teaching Multimedia teaching can be said to be a breakthrough technology in the field of education, because multimedia teaching greatly facilitates teachers' teaching methods. Due to the emergence of multimedia, teachers no longer need to write on the blackboard, wasting time. As long as the courseware is ready, they can project it and let the children learn knowledge in time. It can be said that a lot of unnecessary waste time is saved, and children can have more time to remember and learn.

Second, distance online teaching has the greatest impact on our lives now, because many children can now study online and listen to some courses taught by teachers through the network. Especially during the epidemic, children can't attend classes at home, and they can also listen to the courses taught by teachers through computers without falling behind in their learning progress. If you don't know anything, you can watch the playback and continue to understand, which can be said to make learning easier.

Thirdly, 3D demonstration animation impressed me deeply at school, because many models in previous math textbooks needed to be imagined by their own brains, which was very difficult for some children with poor imagination. However, with this technology, they can be clearly displayed on the projection, which makes them deeply impressed.
