运用知识迁移规律,让学生探索数学知识,是当前数学教学方法改革的一个方面。但鉴于小学数学特点、小学生的心理特点和年龄特点,小学生探索数学知识离不开教师的启发诱导,探索过程中教师仍然要起主导作用。学生探索数学知识过程中教师的主导作用主要体现在以下四个方面。一、为探索新知识做铺垫。学生在学习新知之前,究竟需要哪些旧知,学生心中往往是无数的。因此,教学时要组织复习,为探索新知做铺垫。复习的内容应该是为学习新知所必需具备的基础知识。例如要学生探索和发现“除数是小数的除法的计算法则”,需要哪些基础知识,教师要认真研究。除数是小数的除法,是把除数化为整数以后要使商不变,被除 The use of knowledge transfer rules, so that students explore mathematical knowledge is one aspect of the current mathematical teaching methods. However, in view of the characteristics of primary school mathematics, pupils' psychological characteristics and age characteristics, primary school students can not rely on the teacher's inspiration to explore mathematical knowledge. Teachers still play a leading role in the exploration process. Students in the process of mathematical knowledge to explore the leading role of teachers is mainly reflected in the following four aspects. First, to pave the way for exploring new knowledge. Students before learning new knowledge, what exactly what the old knowledge, the hearts of students often countless. Therefore, teaching review should be organized to pave the way for the exploration of new knowledge. The content of review should be the basic knowledge necessary for learning new knowledge. For example, to ask students to explore and find “divisor is a decimal division of the law of calculation,” what are the basic knowledge needed, teachers should carefully study. Divisor is the division of the decimal, is the divisor into an integer to make business invariant, was removed
