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.

动手实验室类是入门物理经验的关键和独特的元素，但是有效实验室的实施既具有挑战性又昂贵。一个特定的问题是，在小型课程中非常有效的方法可能很难扩展到大型入学课程。该项目的目的是为实验室（ISLE）采用强大而验证的方法，并将其与伊利诺伊大学互动在线实验室（IOLAB）开发的廉价无线实验室系统相结合，以启用任何大型物理学类实验室组件的创新方法。最近涉及伊利诺伊大学数百个介绍性物理学专业学生的试点研究表明，从传统的以高度结构化概念性概念化的实验室转变为一种更加非结构化的方法，这种方法强调了强调实验性设计，感知性的制作和科学交流的方法，实际上可以提高学生的能力来解释数据和科学理由，对概念理解没有负面影响。这些结果尤其令人鼓舞，因为试验研究中使用的方法本质上是可扩展的，并且IOLAB系统便宜且容易获得。该项目的目的是评估将开发的内容和教学法为每个学期的所有3000名参加入门物理学的学生提供基于设计的实验室。这项工作的关键部分将是开发所需的工具和培训，以使这种新方法无法获得以前经验的教师和教学助理。
