A Revision of Investigatons in Number, Data and Space: Focus on Algebra and Assessment

“数字、数据和空间调查”是一门小学数学课程，反映了在K-5年级数学学习和教学方面的研究和最佳实践。从1990年开始，国家科学基金会资助了原始课程的开发。这次修订的《调查》课程将侧重于将代数思维融入整个课程，开发综合评估工具，并加强数量和操作链。这项工作的依据是来自实地的反馈，以及最近关于改进数学课程的建议。这些修订将在一个由学校系统合作伙伴、教师合作者和教育领导人组成的已建立的网络中进行和测试。除了修订课程外，该项目还将编写材料，支持教师实施课程。还将为家长和管理人员编写其他材料。该项目的总结性评估将包括纵向学生成绩数据，跟踪两组学生，每组为期三年。成本分担将包括出版商Scott Foresman和开发商TERC的大量贡献。

"Investigations in Number, Data and Space" is an elementary school mathematics curriculum which reflects research on, and best practices in, learning and teaching mathematics in grades K-5. NSF funded the development of the original curriculum, starting in 1990. This revision of the "Investigations" curriculum will focus on the integration of algebraic thinking throughout the curriculum, the development of comprehensive assessment tools, and the strengthening of the number and operations strand. This work is informed by feedback from the field, as well as by recent recommendations for improving the mathematics curriculum. These revisions will be carried out and tested in an established network of school system partners, teacher collaborators and educational leaders. In addition to revising the curriculum, the project will develop materials to support teachers as they implement the curriculum. Additional materials will be developed for parents and administrators. The summative evaluation of the project will include longitudinal student achievement data, following two groups of students for three years each. Cost sharing will include substantial contributions from the publisher, Scott Foresman, and the developer, TERC.
