Abstract Taking aluminum and its compounds as an example, this paper made a survey of 180 senior students who came from Beijing district-level demonstration school using the self-designed 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 structure of refinement in the teaching process that was beneficial to the extraction of chemical knowledge.
