科学标准指出:“学生对科学知识的学习始于他们在生活实践中对自然界的认识,而不是单纯对书本知识的记忆和接受。因此,必须关注学生原有认识对科学学习的影响,借助各种教育资源,引导学生认识原有经验的局限性,主动建构科学知识,学习科学方法,发展科学探究能力。”针对该要求,在科学教学中采用类比法有利于建立概念,突破难点,加强新旧知识联系,构建完整知识体系,还能够加强学法指导,引导学生形成解题策略。同时对培养学生的理解能力、
The scientific standard states: “Students ’study of scientific knowledge starts from their understanding of nature in life practice, not mere memory and acceptance of book knowledge. Therefore, it is necessary to pay attention to the influence of students’ original understanding on science learning. A variety of educational resources to guide students to understand the limitations of the original experience, take the initiative to construct scientific knowledge, learn scientific methods, the development of scientific inquiry capabilities. ”In response to this requirement, the use of analogy in science teaching is conducive to the establishment of concepts, breakthrough difficulties, Strengthen the old and new knowledge links, build a complete knowledge system, but also to strengthen learning guidance, guide students to form a problem solving strategy. At the same time to develop students’ ability to understand,
