This planning grant will enable the transition to larger-scale, more rigorous testing of a technology and curriculum project (SimCalc) whose aim is to make generally available the mathematics of change and variation by incorporating dynamic, computer-based representational tools into the classroom experience of middle-school children. SimCalc's aim is to make mathematical concepts such as "rate" become available to students without an algebra prerequisite, and push the boundaries of what K-12 learners can master. SimCalc was developed and tested in variety of settings including some of the lowest performing districts in two states, and one class in which English was a first language for only 35% of the students. The collaborations in the planning process will help design rigorous experiment that will analyze how to produce the desired effects with diverse students in varied educational settings and with teachers who vary in their sophistication about and comfort with technology. Findings from the long-term research could influence an understanding of what "high expectations" are possible to achieve for all students, and the role of technology, curriculum, and teacher support in reaching those expectations.

这项规划赠款将使过渡到对技术和课程项目（SimCalc）进行更大规模、更严格的测试，其目的是通过将动态的、基于计算机的表示工具纳入中学儿童的课堂经验，使变化和变异的数学普遍可用。SimCalc的目标是让没有代数基础的学生也能使用“速率”等数学概念，并突破K-12学生掌握的界限。SimCalc在不同的环境中进行了开发和测试，包括在两个州的一些表现最差的地区，以及一个只有35%的学生以英语为第一语言的班级。规划过程中的合作将有助于设计严格的实验，以分析如何在不同教育环境中的不同学生和对技术的熟练程度和舒适度不同的教师中产生预期的效果。长期研究的结果可能会影响对所有学生可能达到的“高期望”的理解，以及技术、课程和教师支持在达到这些期望方面的作用。
