摘　　要： 元素化合物知识是中学化学教学内容的重要组成部分，挖掘元素化合物知识的教学价值，研究其教学策略，提高元素化合物知识的教学效果，对提高中学化学整体教学质量具有重要意义。分析元素化合物知识的教学价值，构建了两种促进元素化合物知识教学价值实现的教学策略，以硫及其化合物的教学为例，采用课堂观察、学生访谈、问卷测查等定性与定量相结合的分析研究方法，对基于具体物质和基于转化的元素化合物知识教学的两种教学策略进行了实证研究，研究结果表明两种教学策略对教学价值的实现和核心教学目标的达成都有效，但是基于转化的元素化合物知识的教学策略教学效果更加显著，值得重视。 Knowledge of elements and compounds is important teaching content of chemistry in middle schools. It is meaningful for high school chemistry teaching to explore the value of elements and compounds teaching and to study the relevant teaching strategy. In this article, the teaching value of the knowledge of element and compound has been analyzed, and two teaching strategies have been constructed, which are the strategy based on specific substances and the strategy based on conversion process. Then taking the teaching of sulfur＆ sulfur compounds as examples, the efficiency of these two teaching strategies is examined by both qualified and quantified research including classroom observation, interview, questionnaire, etc. It has been concluded that the two strategies are both effective and the effect of teaching based on conversion process is more significant.
