爱因斯坦说:“教育就是当一个人把在学校所学的全部忘光之后剩下的东西。”对于小学科学教育,学生学习的绝不仅仅是会被遗忘的、会过时的科学知识、概念,而应该是科学的核心概念。而在以往的小学科学复习课中,看到更多的是将知识总结、归纳灌输给学生,没有从培养学生科学素养的角度出发,而在小学科学课中,单元复习课是一个单元科学小概念的总结,起到完善知识结构、扩展知识技能的作用,是整个单元各课小概念的汇总,因此更容易形成上一层次的科学核心概念,从而培养学生的学习能力,促进他们对生活相关事件和现象的理解。通过在复习课中搭建单元内容过程性出现、单元内容对照呈现、梳理单元教学重点三个载体,促进学生科学核心概念的养成。 Einstein said: “Education is what remains after a person has forgotten everything he has learned at school.” For primary science education, students learn more than just forgotten and obsolete science Knowledge, concept, but should be the core concept of science. In the previous elementary school science review class, I saw more of the knowledge is summed up, instilling a sense of indoctrination to students, not from the perspective of cultivating students’ scientific literacy, and in elementary science class, the unit review class is a small unit science The concept of summary, played a perfect knowledge structure, the role of knowledge and skills to expand, is a small unit of the entire concept of the unit summary, it is easier to form a higher level of the core concepts of science, so as to develop students’ learning ability and promote their life-related Understanding of events and phenomena. Through the process of reviewing the construction of unit content, the content of the unit is presented in a controlled manner, and the three main teaching points of the unit are sorted out so as to promote the development of students’ core concepts of science.
