本研究旨在探讨平衡量表在学生等号关系理解中的中介作用。参与者包括21名幼儿园二年级学生,他们参加了一项早期代数课堂干预,该干预的部分重点是通过使用天平来发展对等号的关系理解。学生们参加了干预前、干预中和干预后的访谈,在这些访谈中,他们被要求评估真假方程并解决开放的数字句子。在解决这些任务时,学生们经常使用天平。访谈分析揭示了这些工具在支持学生对等式的创造性思维方面的几种承受能力。
This research focuses on ways in which balance scales mediate students’ relational understandings of the equal sign. Participants included 21 Kindergarten–Grade 2 students who took part in an early algebra classroom intervention focused in part on developing a relational understanding of the equal sign through the use of balance scales. Students participated in pre-, mid- and post-intervention interviews in which they were asked to evaluate true-false equations and solve open number sentences. Students often worked with balance scales while solving these tasks. Interview analyses revealed several categories of affordances of these tools for supporting students’ productive thinking about equations.
