This award supports a physics education project designed to help students learn ?generic expert skills? including sense-making of the answer (scaling and ratios, special and limiting cases, dimensions and units, exploiting symmetry, and especially estimation), as well as understanding that physics comes from a few principles. The project is based on three principles: a survey showing that professors very much want to teach these things, the use of online problems with embedded tutoring to help students learn, and plans to disseminate both the problems and a diagnostic test created from them to 200,000 students per year (which requires only one mouse click by their instructor). The plan is to distribute both the diagnostic test and the library of problems that tutor expertise in two ways: over the web to teachers (public domain) and through a commercial product (Mastering Physics) that currently reaches about 100,000 introductory physics students annually, but is expected to double this in the coming few years.

这个奖项支持一个旨在帮助学生学习的物理教育项目。通用专家技能？包括对答案的理解（比例和比率，特殊和极限情况，维度和单位，利用对称性，尤其是估计），以及理解物理学来自一些原理。该项目基于三个原则：一项调查显示，教授们非常想教这些东西；利用嵌入辅导的在线问题来帮助学生学习；计划每年向20万名学生传播这些问题和根据这些问题创建的诊断测试（教师只需点击一次鼠标）。该计划以两种方式分发诊断测试和指导专业知识的问题库：通过网络向教师（公共领域）和通过商业产品（精通物理），目前每年约有10万名入门物理学生，但预计在未来几年内将增加一倍。
