Abstract: With the rapid development of "Internet +", it provides a strong and powerful technical guarantee for the application of precise classroom teaching in physics teaching in junior high school. While innovating the teaching mode of junior high school physics, it also ensures the effective implementation of precise classroom teaching activities. However, the current situation of physics teaching in some junior middle schools is not optimistic, and there are still some problems that reduce the efficiency of accurate classroom teaching. Based on this, this article aims at improving the current situation of physics teaching in junior middle school and promoting the effective implementation of accurate classroom teaching in junior middle school physics teaching, and provides some targeted and effective countermeasures for reference.

Key words: Accurate classroom, Junior physics, The classroom teaching
