摘　　要：以“金属铝及其化合物”为例用自编试题对180名来自北京市区级示范性学校的高一学生进行调查，结果显示：不同类型学生对于元素化合物知识的掌握存在明显差异。提出教学对策与建议：无论学生基础如何，教师都应当引导学生分析知识背后的本质原理；教师应当意识到不同类型学生的个性差异和不同的学习需求；在教学过程中应当着重强调知识结构精致化，以利于学生化学知识的提取。Taking aluminum and its compounds as an example, this paper made a survey of 180 senior students who came from Beiiing district-level demonstration school using the self-de- signed test. The results showed that different students had obvious differences on mastery of the chemical elements knowledge. This paper put forward the following teaching countermeasures and suggestions： no matter what the basis of students were, teachers should guide students to analyze the essence behind knowledge; teachers should be aware of different grades of students＇ individual differences and different learning needs; teacher should emphasize the knowledge struc- ture of refinement in the teaching process that was beneficial to the extraction of chemical knowl- edge.
