新课标中要求:“逐步培养学生能够有条理有根据地进行思考,比较完整地叙述思考过程,说明理由。”实现这一目标,数学课堂中学生说理能力的培养显得更为重要。我们应当把培养学生的数学语言和数学知识的学习紧密地结合起来,将它看成是数学学习的重要组成部分,这样才能更好地培养学生数学说理能力。 The new curriculum standard requires that: “gradually develop students to be able to think in a structured way, more complete narrative thinking process, explain the reasons. ” To achieve this goal, the cultivation of students’ ability to speak in mathematics classroom is even more important. We should closely integrate the training of students’ mathematics and mathematics knowledge, and regard it as an important part of mathematics learning so that we can better train students’ mathematics reasoning ability.
