Raising the Floor: The Development of Selected Experientially Based Mathematics Instructional Modules for Previously Under-Served Target Populations

将开发两个高中代数模块，以与当前关于学生学习的研究保持一致。每个单元将跨越4至6周的课堂教学；融入技术的使用；并包括一个课程单元、教师指南、评估材料和支持社区数学素养活动的材料。其中一个模块将使用“道路着色问题”向学生介绍函数，并为矩阵乘法奠定基础。另一个模块将使用游戏来提高学生的数学理解能力，并将帮助学生学习多项式，并介绍基本的计数和概率概念。这些材料将体现一种教学方法，学生通过仔细观察和系统分析熟悉的事件而产生数学，这些事件具有丰富的数学知识。使用这些材料的教师将通过在线合作形成专业社区。这些材料将在几个地理和人口结构不同的地点进行试点和实地测试。该项目将包括形成性和总结性评价部分。

Two high-school algebra modules will be developed consistent with current research on student learning. Each module will span from four to six weeks of classroom instruction; incorporate the use of technology; and include a curriculum unit, teacher guide, assessment materials and materials to support community-based mathematics literacy events. One module will use the "Road Coloring Problem" to introduce students to functions and lay the groundwork for matrix multiplication. The other module will use games to enhance students' mathematical understanding, and will help students learn polynomials and introduce elementary counting and probability concepts. The materials will embody a pedagogical approach whereby mathematics emerges from students' careful observation and systematic analysis of familiar events that are mathematically rich. Teachers using the materials will form professional communities by collaborating online. The materials will be pilot- and field-tested in several geographically and demographically diverse sites. The project will have formative and summative evaluation components.
