SBIR Phase II: Web-Based Urn Sampler and Statistical Authoring Environment

这个小型企业创新研究（SBIR）第二期项目将制作基于网络的课件，其中包括围绕统计学中的模拟/重新采样方法构建的软件（“瓮采样器”），该软件侧重于制定统计测试的过程。本课程还将以统计文本（Stout， Marden和Travers的统计：使数据有意义），自我评估工具，“虚拟教授”帮助系统，“虚拟统计咨询实验室”和入门级基于电子表格的统计软件为特色。目标市场是学习统计学入门课程的学生，他们会像现在购买课本一样购买产品。该课件旨在利用最新和最标准的网络技术，这些技术预计将在项目开发阶段结束时到位。该计划结合了网络结构的力量和新的重新采样技术，为统计学学生创造了一个独特的学习环境。瓮样器将是一个开放和灵活的实验室工具，可以让教师创建练习来补充课堂讲课和其他课程材料。这将使教授新的计算密集型重采样方法变得容易，这种方法在统计推断教学中已被证明是成功的。它面向不同的受众，包括选修定量推理或统计学必修课的本科生和研究生，选修统计学本科专业或辅修专业的学生，以及学习统计学的研究生和继续教育的学生。额外的产品销售将通过购买部分网络产品的学生，他们的导师采用了Stout等文本以外的文本。

This Small Business Innovation Research (SBIR) Phase II project will create web-based courseware featuring software (the "Urn Sampler") built around the simulation/resampling method in statistics which focuses on the process of formulating a statistical test. This courseware will also feature a statistics text (Statistics: Making Sense of Data by Stout, Marden and Travers), self-assessment tools, a "Virtual Professor" help system, a "Virtual Statistics Consulting Lab," and entry-level spreadsheet-based statistical software. The target market is students in introductory statistics courses, who will purchase the product just as they now purchase texts. The courseware aims to leverage the latest and most standard web technologies that are anticipated to be in place at the conclusion of the project's development phase.The plan combines the power of a web-based structure with the new resampling techniques to create a unique learning environment for statistics students. The Urn Sampler will be an open and flexible lab tool that will let teachers create exercises to supplement class lectures and other course materials. It will make it easy to teach the new compute-intensive resampling methods that have proven successful in teaching statistical inference. It addresses a diverse audience, including undergraduate and graduate students taking a required course in quantitative reasoning or statistics, students taking an undergraduate major or minor in statistics, and graduate students studying statistics and continuing education students. Additional product sales will come through purchases of parts of the web product by students whose instructors have adopted a text other than the Stout, et al. text.
