重视知识形成的过程是数学课程改革的一个重要理念。新课标强调:要让学生亲身经历、自主探究、调动多种感官参与教学过程,培养学生的观察、思考、协作能力。因此,根据新课程理念和“先学后导,自主互助”的教学模式,考虑学生已有的知识、生活经验和认知特点,结合教材内容,让学生在情景中学习;在探究中发现;在操作中感悟。让学生在活动中发现问题,解决问题,感受局部和整体的关系,亲身体验从不同的位置观察到物体的面是不同的。在操作、推理、反思的过程中较好地培养学生思维的独立性和灵活性,促进学生养成有序思维的好习惯。
Emphasis on the process of knowledge formation is an important concept of mathematics curriculum reform. The new curriculum emphasizes: let the students experience, self-exploration, mobilize a variety of senses to participate in the teaching process, develop students’ observation, thinking, collaboration ability. Therefore, based on the new curriculum concept and the teaching mode of “prior learning, self-help and mutual assistance”, considering the existing knowledge, life experience and cognitive characteristics of students, combined with the content of teaching materials, students can learn in scenarios; Found; perception in the operation. Let students find problems in the activities, solve problems, feel the relationship between the local and the overall experience of objects from different locations to observe the surface is different. In the process of operation, reasoning and reflection, it is better to cultivate the independence and flexibility of students ’thinking and promote students’ good habits of developing orderly thinking.
