“间隔排列(探索规律)”是学生正式探索规律的起始课。这一课内容在最新修订的苏教版小学数学教材过程中从四年级上册移到了三年级上册,教材难度相对降低了很多。那么是否意味着对学生、对老师的要求降低了呢?答案明显不是。教材在这一课体现学生主体地位的目的更加明显、培养学生自主探索能力的目标提高了。因此,教师要应及时做出教学改变,让学生能够成功地发展数学能力。一、课前思考1.读懂教材教材调整后的内容与以前相 “Arrangements (explore the law) ” is the students begin to explore the law of the initial class. The contents of this class in the latest revision of the primary school mathematics textbook version of the Soviet Union from the fourth grade to the third grade on the books, the difficulty of teaching materials is relatively reduced a lot. Does that mean less demand on students and teachers? Clearly not. The purpose of teaching materials to manifest the dominant position of students in this course is more obvious, and the goal of training students to explore their own capabilities has been raised. Therefore, teachers should make timely teaching changes, so that students can successfully develop mathematical ability. First, pre-class thinking 1.
