? The junior middle school mathematics observation class is taught by Mr. Wan He of Grade 9 and Grade 8 and Mr. Liu of Grade 7.
? The content of teacher Lv Ying's lecture is the ninth grade review class "Hand in Hand Model-congruent triangles". Teacher Lv Ying's classroom arrangement is reasonable and orderly, with layers of decomposition and bedding in place. The selection of examples is reasonable, gradient, clear in class and focused. And through a changeable topic, stimulate students to think independently and draw inferences from others. Starting with special topics, close to the senior high school entrance examination, teaching students to solve problems step by step, learning to reorganize and integrate knowledge, forming a system, and transforming knowledge into ability.
? Teacher Wan brought us the common factor method, and finally started teaching around the learning objectives of this class. Each link is interlocking, clear-cut, and the exercises are firmly set. He is good at summing up the methods of solving problems, and the topic design is from shallow to deep.
? Teacher Liu's teaching design is rigorous in structure, interlocking and natural in transition, combining lectures with practice, and combining lectures with practice, closely following the theme. Paying attention to students' display has fully mobilized students' learning enthusiasm, and the classroom atmosphere is active, which highlights students' dominant position and has obvious teaching effect. In class, Mr. Liu constantly summarizes the blackboard writing, which is clear, neat and beautiful.
? After three observation classes, the junior high school math group discussed at 504. The instructor first gave a detailed explanation on how to design this class, how to build steps and how to guide students to design. Each teacher in the group shared his feelings about the three demonstration classes, and conducted in-depth analysis and heated discussion on the teaching goal design, teacher-student interaction and teaching feedback of these three classes. Teachers actively express their views and opinions, put forward their own questions and improvement measures, and the collision of thinking brings more experiences! Teacher Li Haixia and Director Zhang Shengyuan, the leaders of the Mathematics Group, made a summary speech on this activity class, made a concise evaluation of three open classes, determined the next direction of efforts, and gave guidance to the problems existing in the teachers' classroom, so that teachers can follow rules, have laws to follow, have clear goals, and strive to achieve one lesson, one method and one lesson.
? Efficient classroom, junior high school mathematics group has been exploring the road, taking this round of open class as an opportunity to sum up the existing experience and find their own new growth point, so that every teacher can gain something in teaching, and take this as a new starting point, keep learning, exploring, reflecting and improving, pay attention to practice, and promote the high-quality, harmonious and healthy development of classroom teaching in our school!
