采用2×2×4三因素混合实验设计,对不同年级学生解比较应用题过程中的各种指标进行分析,结果表明:学生解比较应用题时的问题表征策略存在显著的年级差异;数学成绩优生、差生存在不同的问题表征策略;题目呈现方式对学生的问题表征策略有显著影响。
Using 2 × 2 × 4 three-factor mixed experimental design, the analysis of various indicators in different grade students’ comparison and application problems shows that there are significant grade differences in the student’s problem solving strategies when comparing applied questions. Eugenics, poor students exist different problem characterization strategies; topic presentation methods have a significant impact on the students’ problem characterization strategies.
