Exploration of the Application Strategies and Value of Stratified Teaching in the Teaching of Pythagorean Theorem in Junior High School Mathematics

随着新课程改革的深化，初中数学教学愈发注重“以学生为本”的教育理念。面对学生数学基础、学习能力和兴趣的显著差异，分层教学成为实现因材施教的有效途径。本文以勾股定理的教学为例，结合分层教学的理论基础和实践策略，从学生分层、教学目标分层、教学方法分层以及教学评价分层四个维度展开探索，旨在通过差异化教学策略满足不同层次学生的需求，提升课堂教学效率，培养学生的数学核心素养。With the deepening of the new curriculum reform, the teaching of mathematics in junior high school increasingly emphasizes the educational concept of “student-centeredness”. Faced with significant differences in students’ mathematical foundations, learning abilities and interests, stratified teaching has become an effective way to implement individualized instruction. This article takes the teaching of the Pythagorean theorem as an example, combines the theoretical basis and practical strategies of stratified teaching, and explores from four dimensions: student stratification, teaching objective stratification, teaching method stratification, and teaching evaluation stratification. The aim is to meet the needs of students at different levels through differentiated teaching strategies, improve classroom teaching efficiency, and cultivate students’ core mathematical literacy.
