摘要
PCK是学科知识和教学法知识的结合体.“物质的量”属于高中化学概念教学部分的难点内容,将教师PCK应用于“物质的量”的教学,可以达到突破难点且高效教学的目的.以“物质的量系列概念”为主题,采用PCK理论为核心思想,将整个教学环节用知识线、素养线、策略线、兴趣线与评价线这五个线索串联起来并贯穿于教学的全过程.采用生活实例并创设特殊情境,运用问题驱动、类比归纳以及合作学习等策略帮助学生理解“物质的量”概念.将此教学设计进行实践后,采用问卷法和访谈法,检验教学效果和学生听课感受,发现教学效果良好.
PCK is a combination of subject knowledge and pedagogical knowledge."Quantity of Matter"belongs to the difficult content of chemistry concept teaching in senior high school.Applying teacher's PCK to"Quantity of Matter"teaching can break through the teaching difficulties.With the theme of"Quantity Series Concept of Matter"and PCK Theory as the core idea,the whole teaching process is connected with five clues,namely,knowledge line,accomplishment line,strategy line,interest line and evaluation line,and involves the teaching process.To help students understand the concept of"Quantity of Matter"by using life examples and creating special situations,using strategies such as problem-driven,analogical induction and cooperative learning.When the teaching design is put into practice,questionnaire and interview are adopted to test the teaching effect and students'experience of attending the class,and it is found that the teaching effect is good.
