In order to promote the rapid growth of young teachers in the school, further improve the level of teacher education and teaching, optimize classroom teaching, and strengthen communication among teachers, Lanzhou Chenggong High School organized outstanding teachers of various subjects to demonstrate high-quality demonstration lessons, giving full play to experienced and capable teachers. The teacher plays a leading role in modeling. On May 24th, the first class in the morning of Monday, Teacher Ma Jun, the leader of the physics group of the first grade of senior high school, gave a high-quality demonstration lesson to Class 1 of the first grade of senior high school. The topic is selected from the first section of Chapter 7 of the People's Education Press Compulsory Course 1 "Gravity Potential Energy", which is the energy that an object has due to being lifted high. (The energy that interacting objects have due to their positions is called potential energy.)
Video introduction + explanation by famous teachers
group discussion + walking inspection
First, Teacher Ma gave the teaching objectives of this lesson on the blackboard, starting from the work of gravity and the potential energy of gravity , the calculation of the gravitational potential energy of special objects is carried out in three aspects. Then it is introduced through the video. The "stake driving" link in the video introduces the work of gravity and the potential energy of gravity. Then, through the explanations of famous teachers, students can understand in advance. Next, Teacher Ma organized a group discussion with students to collaboratively explore the first "gravity work". Using the micro-element method, they concluded that the gravity work has nothing to do with the path and is only related to the initial and final position heights; they collaborated to explore the second "gravitational potential energy" from the concept , the formula relates to the change in potential energy and work. At the end of the course, Teacher Ma also presented two example questions through PPT for students to practice and then explained them to students to achieve a combination of lecture and practice.

Questioning students
During the teaching process, Teacher Ma carefully wrote down the key points of the teaching content, interacted with the students at the same time, asked questions discussed by the students, and answered the exercises.

The classroom content of this demonstration class is rich and colorful, the content is compact and gradient. Teacher Ma uses his own unique teaching method to create a lively learning atmosphere. The teacher teaches relaxedly and the students Have fun learning, create an efficient classroom, and provide a good reference for the teachers who attend the class. Demonstration classes are a combination of teaching practice and the latest educational concepts. They are an indispensable and important part of school teaching activities. They promote the exchange and discussion of teaching experience among teachers and benefit a lot.
