小学数学是基础性学科,其内容来源于生活,学生学习数学的过程实际上就是将生活经验转化为数学经验的过程,中科院张梅玲老师在《新课程理念下的课堂教学》讲座中强调:“教师要尽量还原教材的生活本色,能从生活中引入的,尽量从生活中引入。”那么如何做到小学数学“生活化”呢?一、技能训练“生活化”技能训练是小学数学“双基”训练的要求之一,一味的技能训练必然导致枯躁,引起学生的厌倦情绪,而技能训练“生活化”则要求训练材料应尽可能来自生活,训练目的则着眼于学以致用。在教长方形面积这一课时,我是这样设计的:假期里我们教室地面要铺方砖,如何合理地铺砖呢,分组讨论后再组织全班讨论,大家达成共识:(1)首先要测量教室的长、宽;(2)计算出
Elementary mathematics is a basic discipline, its content comes from life, the process of students learning mathematics is actually the life experience into the mathematical experience of the process, the Chinese Academy of Sciences teacher Zhang Meiling in the “new curriculum concept of classroom teaching,” lecture stressed: Teachers should try to restore the true nature of the textbook, can be introduced from life, as far as possible from the introduction of life. “So how to do primary school mathematics ” life “? First, the skills training” life skills training Is the primary school mathematics “double base ” training requirements, blindly skills training will inevitably lead to impatience, causing students to weariness, and skills training “living ” requires training materials should be as far as possible from life, training The purpose is to learn to apply. In teaching the rectangular area of this lesson, I was so designed: During the holiday we classroom floor tiles, how to properly paving brick, group discussion and then organize the class discussion, we reached a consensus: (1) first of all to measure the classroom Length and width; (2) calculated
