A Longitudinal Comparison of the Effects of the Connected Mathematics Program and Other Curricula on Middle School Students' Learning of Algebra

本项目将比较使用互联数学项目对代数学习的影响与使用其他（非国家科学基金会支持的）中学数学课程材料的影响。该项目要解决的研究问题是：在CMP课程和非CMP课程中，代数的预期处理有什么异同？对于学生和教师来说，CMP和非CMP体验的关键特征是什么？这些特征如何解释CMP和非CMP学生的表现差异？CMP学生和一组可比较的非CMP学生在测量广泛的数学思维和推理技能（以代数为重点）的任务上的表现有什么异同？要评估的代数重点技能/概念是：概念理解和问题解决；代数运算技巧；解决策略，表示和数学证明。

This project will compare the effects on algebraic learning when using the Connected Math Program to the effects of using other (non-NSF supported) middle school mathematics curriculum materials at the middle school level. The research questions to be addressed by the project are: What are the similarities and differences between the intended treatment of algebra in the CMP curriculum and in the non-CMP curricula?What are the key features of the CMP and non-CMP experience for students and teachers, and how might these features explain performance differences of CMP and non-CMP students?What are the similarities and differences in performance between CMP students and a comparable group of non-CMP students on tasks measuring a broad spectrum of mathematical thinking and reasoning skills, with a focus on algebra?The algebra focus skills/concepts to be assessed are: conceptual understanding and problem solving; algebraic manipulative skills; solution strategies, representations and mathematical justifications.
