学生已有的知识经验是新知识的生长点,引导学生“生长”新知识,重要的一点是要善于运用学生的已有经验,让学生的已有经验为我们的数学课堂所用,这样对提高学生的学习能力起着事半功倍的效果。在这一过程中,我们要善于引导学生回顾旧知识,巧用“迁移”规律,把所学知识转化成为自己的已有经验,并运用在我们的生活当中,解决生活中的实际问题,这样,学生的学习能力才会得到提高。 The existing knowledge and experience of students is the growth point of new knowledge. It is important to guide the students to “grow” new knowledge. It is important to make good use of the students ’existing experiences so that the students’ existing experience can be used in our math class. To improve the learning ability of students play a multiplier effect. In this process, we should be good at guiding our students to review the old knowledge and use the law of “transfer” to translate the knowledge they have learned into their own existing experience and apply it to our life to solve practical problems in life , So that students learn ability will be improved.
