本研究旨在探讨图式拓展教学对小学二年级学生应用题解决能力和用代数方程表征应用题结构能力的影响。教师(n=18)被随机分配到传统的应用题教学或SBI应用题教学，这两种教学方法教会学生用最重要的方程式来表征应用题的结构和定义特征。干预持续16周。我们对270名学生的应用题技能进行了前测和后测；对数据嵌套结构的分析表明，SBI学生的应用题学习效果更好。对学生应用题作业的描述性分析表明，SBI帮助学生用代数方程表达应用题的结构，这表明SBI促进了学生新出现的代数推理的这一方面。
The purpose of this study was to assess the effects of schema-broadening instruction (SBI) on second graders’ word-problem-solving skills and their ability to represent the structure of word problems using algebraic equations. Teachers (n = 18) were randomly assigned to conventional word-problem instruction or SBI word-problem instruction, which taught students to represent the structural, defining features of word problems with overarching equations. Intervention lasted 16 weeks. We pretested and posttested 270 students on measures of word-problem skill; analyses that accounted for the nested structure of the data indicated superior word-problem learning for SBI students. Descriptive analyses of students’ word-problem work indicated that SBI helped students represent the structure of word problems with algebraic equations, suggesting that SBI promoted this aspect of students’ emerging algebraic reasoning.
