Research, and Revision of the TIMS/Math Trailblazer Elementary Mathematics Curriculum

“数学开拓者”是由美国国家科学基金会（NSF）资助的“综合数学与科学教学”项目开发的一门K-5数学课程，整合了重要的科学组成部分。这个为期五年的项目将对“开拓者”的使用进行研究，并修订课程。这项研究将涉及来自五所大学（伊利诺伊大学芝加哥分校、伊利诺伊大学厄巴纳-香槟分校、明尼苏达大学、圣泽维尔大学和堪萨斯州立大学）的研究人员。它将调查学生的成绩、课程的视频学习以及对学校和社区实施情况的调查。修订工作将包括更新解决问题的背景、审查评价战略、更新技术使用情况和重写若干课程。新的教材将进行实地测试。其他要开发的材料是教师增强模块的修订版和家长指南。评估将作为研究部分的一部分进行。对原提案和开发计划署预算的审查不能支持最初提出的工作计划。经过一些谈判，提议者提交了一份修订后的工作计划和时间表，这些计划和时间表记录在附件中。

Developed with NSF funds through the "TIMS (Teaching Integrated Mathematics and Science)" project, "Math Trailblazers" is a K-5 mathematics curriculum integrating a significant science component. This five-year project will undertake a study of the use of "Trailblazers" as well as a revision of the curriculum. The study will involve researchers from five universities (U. of Illinois, Chicago; U. of Illinois, Urbana-Champaign; U. of Minnesota; St. Xavier U. and Kansas State U.). It will investigate student achievement, video study of lessons, and an investigation of the school and community contexts of implementation. The revision will involve updating problem-solving contexts, a review of assessment strategies, an update on the use of technology and the rewriting of several lessons. New classroom materials will be field tested. Other materials to be developed are a revision of the teacher enhancement modules and a parents' guide. Evaluation will be conducted as part of the research component.The reviews of the orginal proposal and the IMD budget could not support the work plan first proposed. After some negotiation the proposers submitted a revised work plan and timetable which are documented in the jacket.
