The Application Of Classification Discussion Ideas In The Teaching Of Geometry In Junior High School

The purpose of this paper is to explore the application of categorical discussion ideas in junior high school geometry teaching.An empirical study is conducted with parallelogram determination as an example,and corresponding teaching insights are proposed.Through the discussion of the parallelogram determination problem,this paper summarizes the cognitive characteristics and confusions of junior high school students in learning geometry,explores the role of categorical discussion ideas in solving geometry problems,and proposes specific strategies and methods for teaching using categorical discussion ideas.In the teaching practice,this study adopts the idea of categorical discussion to guide students to think independently and discuss interactively so as to deepen their understanding and memory of parallelogram determination.Through the teaching experiment and the investigation of students’ feedback in two classes,some insights were drawn,such as teachers should focus on guiding students to summarize and classify in their teaching to help them form a systematic knowledge structure;at the same time,they should pay attention to students’ learning emotions,stimulate their learning interest and motivation,and promote their active learning.This paper finally presents a lesson plan for the parallelogram determination problem,aiming to help junior high school teachers better apply the idea of categorization and discussion to teach and improve students’ learning effectiveness and interest.This study has some reference value for both practical and theoretical research on middle school geometry teaching.
