教育的最终目的是为了促进学生的发展。《义务教育数学课程标准》在基本理念中明确指出,数学学科教学应该面向所有的学生,让每一个儿童都能得到不同程度的提升。学生是数学课堂的主人,是数学学习的内因,只有充分发挥出内因的决定性作用,才能让数学课堂走向立体化;教师是学生成长的引路人,应借助于多元的教学手段,引领学生积极主动地参与到数学学习中。我们的数学课堂应关注学习的主体,尊重学生已有的认知基础,因学定教;借助于多样的学习途径,与学生一同经历知识的 The ultimate goal of education is to promote student development. “Compulsory Education Curriculum Standards” clearly pointed out in the basic idea that mathematics teaching should be for all students, so that every child can get different degrees of improvement. Students are the masters of mathematics classroom and the internal cause of mathematics learning. Only by giving full play to the decisive role of internal factors can the mathematics classroom be three-dimensional. Teachers are the guide to the growth of students. With the aid of diversified teaching methods, students should be led to take the initiative Participate in mathematics learning. Our math class should pay attention to the main body of study, respect the students’ existing cognitive foundation, decide by reason of religion, and experience the knowledge with students through various learning ways
