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.

本项目将比较使用互联数学程序和使用其他(非国家科学基金会支持的)中学数学课程教材在中学水平上对代数学习的影响。本项目要解决的研究问题是：在化学课程和非化学专业课程中对代数的预期处理有什么相似之处和不同之处？对于学生和教师来说，化学原理和非化学原理课程的主要特点是什么？这些特点如何解释化学原理和非化学原理学生的表现差异？在测量广泛的数学思维和推理能力的任务上，化学化学原理学生和可比的非化学原理学生之间有什么相似和不同之处，重点放在代数上？需要评估的代数重点技能/概念是：概念理解和问题解决；代数操作技能；解题策略、表述和数学论证。
