[Commentary] Recently, Zhang Hui, a physics teacher at the Fourth Middle School of Mile City, Honghe Prefecture, Yunnan Province, became popular on the Internet because of a video of a freehand hack in a classroom. On June 5, the reporter walked into the Fourth Middle School of Mile City and recorded Zhang Hui's "different classroom".

  [Commentary] Zhang Hui told reporters that the video of hacking bricks freehand was recorded in a physics class. This move is a classroom introduction to the new class teaching, the law of momentum. In order to explain this knowledge point to the students more vividly and concretely, he combined it with the stunt of "freehand hacking bricks", which is highly concerned in life, and actually applied it to classroom teaching.

  [Same period] (Zhang Hui, the fourth middle school teacher in Mile City, Yunnan Province) The equivalent of my introduction is to attract their attention, and then I started to introduce a new class. After importing, I will use my knowledge in this lesson to make a reasonable analysis of what I imported. For this purpose, I used my mobile phone to ask a classmate to help me record this process.

  [Explanation] In the classroom, Zhang Hui also slowed down the video of freehand brick splitting, so that students can observe and grasp the details of "freehand brick splitting" more carefully, and use physics knowledge to analyze and understand, deepen the memory of knowledge.

  [Same period] (Zhang Hui, Teacher, Fourth Middle School, Mile City, Honghe Prefecture, Yunnan Province) Actually, the ultimate purpose of my class is to tell students that when we see many phenomena in our social life, we should not go blind to worship or blind To pursue, we should use what we have learned to analyze and judge rationally and scientifically.

  [Commentary] The reporter learned that in the usual teaching work, Zhang Hui often incorporates interesting cases like "freehand brick" and actual life into the teaching, and even even made some physical props for class by himself.

  [Same period] (Lai Jinpeng, a student in the Fourth Middle School of Mile City, Honghe Prefecture, Yunnan Province) Teacher Zhang Hui's teaching method is very novel and interesting, and he is good at bringing everyone to understand relevant physics knowledge through experiments. The props he uses are also very novel and interesting, which attracts the attention of our classmates and at the same time allows us to better understand physical knowledge.

  [Commentary] Zhang Hui told reporters that he never thought of the sudden popularity on the Internet. He just purely wanted to use his own teaching methods, combined with actual life, to use physical knowledge to analyze these phenomena with students to make it easier for students to understand physical knowledge.

  [Same period] (Zhang Hui, Teacher of the Fourth Middle School of Mile City, Yunnan Province) Every teacher what you like and what you are good at, you dedicate all your enthusiasm, all passions, all responsibilities to students, I think it is a very Great teacher.
