A hands-on lab class is a key and unique element of the introductory physics experience, yet the implementation of effective labs can be both challenging and expensive. A particular problem is that approaches which work extremely well in small classes can be difficult to scale up to large enrollment courses. The goal of this project is to take a powerful and proven approach to labs, the Investigative Science Learning Environment (ISLE), and to combine it with an inexpensive wireless lab system developed at the University of Illinois, Interactive Online Labs (IOLab), to enable an innovative new approach to the lab component of any large introductory physics class. Recent pilot studies involving several hundred introductory physics students at the University of Illinois have demonstrated that moving away from the traditional highly structured concept-focused lab to a more unstructured approach that emphasizes experimental design, sense-making, and scientific communication, can actually improve a student's ability to interpret data and to reason scientifically, with no negative impact on conceptual understanding. These results are especially encouraging since the approach used in the pilot studies is inherently scalable and the IOLab system is inexpensive and readily available. The goal of this project is to assess the content and pedagogy that will be developed to provide similar design-based labs for all 3000 students taking introductory physics at the University of Illinois each semester. A key part of this effort will be to develop the tools and training needed to make this new approach accessible to instructors and teaching assistants that have little prior experience.

动手实验室课程是介绍物理学经验的关键和独特元素，但有效实验室的实施可能既具有挑战性又昂贵。一个特别的问题是，在小班教学中效果非常好的方法可能很难扩大到大型招生课程。这个项目的目标是采取一个强大的和经过验证的方法来实验室，调查科学学习环境（ISLE），并将其与伊利诺伊大学开发的廉价无线实验室系统相结合，互动在线实验室（IOLab），以实现任何大型入门物理课的实验室组成部分的创新方法。最近的试点研究涉及伊利诺伊大学的数百名入门物理学生已经证明，从传统的高度结构化的概念为重点的实验室转移到一个更加非结构化的方法，强调实验设计，意义的制作和科学交流，实际上可以提高学生的能力来解释数据和科学推理，对概念理解没有负面影响。这些结果特别令人鼓舞，因为试点研究中使用的方法具有内在的可扩展性，IOLab系统价格低廉且易于获得。该项目的目标是评估将开发的内容和教学法，为所有3000名学生提供类似的设计为基础的实验室，每学期在伊利诺伊大学的物理导论。这项工作的一个关键部分将是开发所需的工具和培训，使这一新方法能够为以前几乎没有经验的教员和教学助理所利用。
