数学语言具有准确性、规范性和通用性的特点,是数学思维的最佳载体。培养学生使用数学语言的能力,其实质是提高学生分析与解决问题的能力。低年级学生语言表达能力不强,常在数学课堂中出现会做不会说的现象,要解决这一问题就必须根据教材特点,有目的、有计划、多形式地对学生进行数学语言训练。现以《认识线段》一课谈谈如何提高低年级学生数学语言规范性的一些粗浅看法:【案例1】磨课时的师生对话师:同学们,在我们生活中许多物体的边可以看作线
Mathematical language has the characteristics of accuracy, normativity and universality, which is the best carrier of mathematical thinking. The essence of students ’ability to use mathematical language is to improve students’ abilities to analyze and solve problems. The ability of lower grade students to express their language is not strong, often appear in mathematics classes will not do that phenomenon, to solve this problem must be based on the characteristics of teaching materials, purposeful, planned and multi-modal to students in mathematics and language training. Now to “know the line” a lesson to talk about how to improve junior students math language normative some superficial view: 【Case 1】 Teachers and students in the class teacher: classmates, in our lives many objects can be regarded as line
