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.

动手实验室课程是入门物理体验的关键且独特的元素，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展到大班招生的课程。该项目的目标是采用一种强大且经过验证的实验室方法，即调查性科学学习环境 (ISLE)，并将其与伊利诺伊大学开发的廉价无线实验室系统、交互式在线实验室 (IOLab) 相结合，为任何大型入门物理课程的实验室部分提供创新的新方法。最近涉及伊利诺伊大学数百名物理入门学生的试点研究表明，从传统的高度结构化的以概念为中心的实验室转向强调实验设计、意义建构和科学交流的非结构化方法，实际上可以提高学生解释数据和科学推理的能力，而不会对概念理解产生负面影响。这些结果尤其令人鼓舞，因为试点研究中使用的方法本质上是可扩展的，并且 IOLab 系统价格低廉且易于使用。该项目的目标是评估将开发的内容和教学法，以便为每学期在伊利诺伊大学学习物理入门课程的所有 3000 名学生提供类似的基于设计的实验室。这项工作的一个关键部分是开发所需的工具和培训，使缺乏经验的教师和助教能够使用这种新方法。
