Abstract Studying how do high school students to solve problem of element inference can deepen the understanding of chemical problem solving. Using cluster random sampling, students from each class of senior 2 and senior 3 in a senior high school in Hainan province were tested, using the adapted problems of college entrance examination as a tool, using NVivo to analyze students’ written reports, it was found that there were many types of solution and order of elements. This diversity was caused by different ways of representing and solving strategies. Inspiration to curriculum and teaching: using scientific representation, and promote the construction of students’ scientific representation; emphasis on algorithm strategy, correct deviations caused by heuristics.
