摘要
以解决“保存NaOH溶液的试剂瓶为什么不用玻璃塞”这一真实问题为情境,设计3个教学板块:运用分类方法认识物质、对物质进行分类、合成物质,从物质组成和物质变化的认识视角,对物质进行分类,建构分类观。依据物质分类研究同一类别物质的性质及应用,在完成知识结构化的同时,重在凝练基于物质分类及转化的认识视角和认识思路,寻找并体验陌生情境下解决复杂化学问题的突破口和思维框架,发展学生的化学学科核心素养。
In order to solve the real problem of“why glass stopper is not used in reagent bot-tles to preserve NaOH solution”,three teaching sections are designed:using classification meth-ods to recognize substances,classify substances and synthesize substances.From the perspective of material composition and material change,this paper classifies materials and constructs the classification view.In addition to completing the knowledge structuring,it focuses on the cogni-tive perspectives and ideas based on the classification and transformation of substances,finds and experiences the breakthrough point and thinking framework for the study of new substances in unfamiliar situations,and develops students'core literacy of chemistry discipline.
