立足概念教学,培养数学思维

Based on Concept Teaching, Cultivate Mathematical Thinking

课程标准是教材编写、教学以及考试命题的重要依据。《义务教育数学课程标准(2022年版)》明确提出初中阶段侧重于概念学习,对于数学概念的考察,近年中考试题中以概念直接应用、概念关联教材以及概念创新三种类型呈现。本文从上述三种类型着手进行分析,探索教学方法,可以从单元教学,建构知识框架,加工教材,发展高阶思维;深度学习,理解概念本质进行概念课教学。

Curriculum standard is an important basis for the compilation of textbooks, teaching and examination propositions. “Compulsory Education Mathematics Curriculum Standards (2022 Edition)” clearly puts emphasis on concept learning in junior high school. In recent years, the examination questions of mathematical concepts are presented in three types: direct application of concepts, concept related textbooks, and concept innovation. This paper starts with the analysis of the above three types and explores the teaching methods, which can be from the unit teaching, the construction of knowledge framework, the processing of teaching materials, and the development of higher-order thinking;deep learning and understanding the essence of concept teaching.
