Using Case Studies in the Introductory Physics Laboratory addresses two important motivations for laboratory improvement. First, enrollments at the college in both algebra-based and calculus-based introductory physics has more than doubled since 1994 due to increasing numbers of biology chemistry, math and physics majors as well as revitalization of the physics program. Second, a pedagogical renovation of the introductory physics laboratory is needed to better prepare students for the world beyond the classroom and better foster an ability to understand and apply physics. The laboratory program in this project focuses on semester-long team-based Case Studies in which students develop a scientific approach to inquiry and problem solving, reinforce understanding of physics concepts, develop a sense of ownership of their work, experience application of physics to real-life situations, and learn to communicate their research and results. After choosing a topic for Case Study, each student team chooses and defines a self-designed Case Study, and later proposes and conducts a series of tests and measurements. Regular instructor guidance and feedback is given throughout the entire Case Study process. Each team reports preliminary results and proposes additional tests and measurements to be made. Teams conduct Case Studies using a selection of computer-interfaced sensors, digitized video and ordinary lab equipment. Case Study culminates with a physics "open house" and a formal report prepared for the World Wide Web. Case Studies are supplemented with five basic-physics experiments, called Interludes, which develop basic skills and reinforce fundamental physics concepts. Through the Case Study approach, students are encouraged to become active learners and to extend this capability to other academic experiences. Results of this program will be presented at local and national conferences and submitted for publication in appropriate journals; exemplary Case Studies will be posted on the Carthage web page for access by interested parties at other institutions.

在导论物理实验室中使用案例研究解决了实验室改进的两个重要动机。首先，自1994年以来，由于生物化学、数学和物理专业人数的增加以及物理课程的振兴，该学院以代数和微积分为基础的入门物理课程的入学人数增加了一倍多。第二，需要对导论物理实验室进行教学改革，以使学生更好地为课堂之外的世界做好准备，并更好地培养理解和应用物理的能力。本项目的实验室项目侧重于以团队为基础的学期案例研究，在此过程中，学生将培养一种科学的方法来探究和解决问题，加强对物理概念的理解，培养对自己工作的主人主人感，体验物理在现实生活中的应用，并学会交流他们的研究和成果。在Case Study的选题确定之后，每个学生团队选择并定义一个自己设计的Case Study，然后提出并进行一系列的测试和测量。在整个案例研究过程中，定期提供指导和反馈。每个小组报告初步结果，并提出要进行的额外测试和测量。小组使用计算机接口传感器、数字化视频和普通实验室设备进行案例研究。案例研究的高潮是物理“开放日”和为万维网准备的正式报告。案例研究的补充是五个基础物理实验，称为插曲，发展基本技能和加强基本物理概念。通过案例研究的方法，鼓励学生成为积极的学习者，并将这种能力扩展到其他学术经历。该方案的结果将在地方和国家会议上提出，并提交在适当的期刊上发表；示范案例研究将发布在迦太基的网页上，供其他机构的相关人士查阅。
