Abstract According to the characteristics of quantitative experiment review in senior three, the teaching practice based on the cultivation of core literacy of “model cognition” was carried out by taking “determination of molar salt purity” as an example. Research and analysis of teaching background, design ideas, teaching process and other aspects, and carefully select materials to trigger model cognition; high-quality questions, construct model cognition; Combining point, line and plane, enriching model cognition and so on, this paper analyzes and explains the chemistry teaching to promote students’ “model cognition” accomplishment.
