本文以“重复现象”的教学为例,呈现了若干活动片断,包括引导学生重新认识加法,创建问题情境让学生用数学语言表达数量关系,运用辩论的方法加深对知识的理解等,意在探讨如何“让课堂回归数学本色”。笔者以为,数学教学不仅要丰富孩子们的数学知识,更要深刻其数学思维;不仅要改变学生的课堂行为,还要帮助他们逐步建立数学思想。 Taking the teaching of “repetitive phenomena” as an example, this paper presents a number of activities, including guiding students to re-understand the addition, creating problem situations for students to express quantitative relations in mathematical language and using the method of debate to deepen their understanding of knowledge. In discussing how to “let the classroom return to mathematical qualities.” I believe that mathematics teaching not only enrich children’s mathematical knowledge, but also profound their mathematical thinking; not only to change the classroom behavior of students, but also help them to gradually establish mathematical thinking.
