On the afternoon of October 18, 2018, the second demonstration class of "New Era, New Role, New Act" for Party members in this semester was organized orderly under the careful organization of the school's General Party Branch and Teaching Office, and the demonstration class for Party members was lectured by teacher Yu Jing of physics。Ms. Yu Jing taught the eighth class in the multi-function hall, and the teachers of the whole school actively listened to and learned。After class, the teaching and research leaders organized the teachers of the group to discuss and exchange the demonstration lesson。

Yu Jing's lecture topic is "Application of Ohm's Law - Special Measurement of Resistance"。In the course, Teacher Yu Jing designed the learning task of how to measure resistance in the absence of ammeter or voltmeter. After the cooperative learning of each learning group, various methods were given to solve the problem, and the design results and design ideas of each group were exchanged。Teacher Yu Jing gave comments on students' answers, inspired students to find out the commonalities of design methods, and proposed the teaching focus of this lesson "resistance method".。The nine-gong method is used as a teaching aid，Taking resistance measurement and Ohm's law application as teaching clue，It adopts the teaching organization form of given goals and tasks, inter-group cooperative design, out-of-group sharing and communication, and teacher's suggestion and summary，From shallow to deep, good guidance，Accomplished the teaching goal，It matches the characteristics of flexible and open teaching content。After class, Ms. Yu gave a 10-minute lecture, explaining the design ideas of this lesson。

After the end of the class, the teachers of the teaching and research groups conducted in-depth discussion and research on the demonstration course for Party members, summed up the advantages and put forward some constructive suggestions。The teachers agreed that Yu Jing controlled the classroom effectively and made the students' thinking as clear and definite as the water flow of "dividing first and then remitting"。At the same time, the nine-gong formula understanding method has been recognized by many teachers, this method makes difficult physical formulas at a glance, easy for students to remember。In addition, teachers also put forward some suggestions for the teaching process, such as properly highlighting core qualities and using subject terms more accurately。

This activity fully embodies the spirit of our school's party members and teachers to forge ahead and take on responsibilities，It shows the strong teaching and teaching research ability of the party teachers，At the same time, it opens up the teaching ideas of all teachers and enriches the teaching methods，It has built an efficient platform for the teaching and research exchange of various disciplines in the school，It also lays a foundation for our school teachers to improve their overall teaching ability。
