Collaborative Research: Inspiring undergraduate engagement in advanced laboratories through web-based interactive video

该项目正在开发带有交互式视频的基于网络的活动，以激励物理和工程专业的本科生在高级实验室工作，建立处理实验室遇到的技术问题的信心，并加强跨多个课程的当代主题的教学。尽管不同机构的先进物理实验室的作用可能存在很大差异，但在每种环境中，成功的实验室体验都应努力为学生提供既具有教育意义又具有启发性的创造性体验。该项目中的活动提供了一个交互式视频环境，向学生介绍高级实验室中的重要主题领域，并能够交互式地控制测试参数。然后，学生可以在熟悉物理原理和所涉及的设备的情况下在实验室开始实验。这些活动旨在提供一个类似实验室的交互式环境，重点关注实验室主题的本质，但剥离了真实实验室体验的许多复杂性。 这些活动旨在丰富高级实验室主题的学习和学生的热情，为物理学提供坚实的入门框架，并在实际实验室中带来更有意义的体验。该项目的结果由教师和学生进行衡量，它们取决于（a）学生对实验所涉及的物理和技术有更深入的理解； (b) 提高​​学生对实验室作为学习环境的态度； (c) 学生更好地掌握实验和实验所涉及的设备。 该项目的工作重点是三个当代且引人入胜的主题领域，这些领域是伯特利大学物理系各种学生项目的基础：(1) 可压缩流体力学，(2) 原子分子和光学 (AMO) 物理学，以及 (3) 等离激元学和纳米光学。智力优势：基于网络的资源已经可以多种形式用于物理教育，包括在线讲座、小程序和在线模拟以及基于网络的作业。视频小插曲也正在开发中，它提供了一个结合了旁白、真实视频和分析工具的在线环境。这里的工作与其他正在进行的项目不同，它强调基于网络的模拟，其中用户与来自高级实验室实验的视频进行交互。因此，用户与基于网络的视频的交互的设计方式为真正的高级实验室实验提供了一个窗口，并为学习、创造力和进一步参与实验室提供了刺激。参与的 BU 教师在先进实验室拥有丰富的教学经验，并带来流体力学、AMO 物理、等离子体激元和纳米光学领域的研究专业知识。罗切斯特理工学院 (RIT) 的合作者凭借其在交互式视频分析方面的工作成为物理教育界的领导者。分析软件是利用软件工程的最佳实践来开发的。更广泛的影响：该项目中产生的活动可在 ComPADRE.org 上公开获取。此外，该软件以开源形式提供，并附有完整的文档，使其他机构能够基于自己的先进实验室和本科生研究开展活动，并向更广泛的受众打开先进实验室社区的大门。每个主题领域的活动都可供采用者和潜在采用者在 2014 年 AAPT 会议的研讨会以及其他会议和研讨会（例如 ALPhA 实验室沉浸）中了解。

This project is developing web-based activities with interactive videos to inspire undergraduates in physics and engineering toward work in the advanced lab, to build confidence in handling the technical aspects encountered in the lab, and to enhance the teaching of contemporary topics across multiple courses. Although the role of advanced physics laboratories can vary significantly from one institution to another, in each environment a successful lab experience should strive for creative student experiences that are both educational and inspiring. The activities in this project provide an interactive video environment where students are introduced to important topic areas in the advanced lab and empowered to interactively control test parameters. Then students can begin the experiments in the laboratory having familiarity with both the physics and the equipment involved.The activities are designed to provide an interactive lab-like environment that focuses on the essence of the lab topic, but is stripped of many of the complexities of the true lab experience. The activities are designed to enrich learning and student enthusiasm in the advanced lab topics, provide a solid introductory framework to the physics, and lead to more meaningful experiences inside the actual laboratory. Results of the project are being measured by instructors and students, and they depend on (a) deeper student understanding of the physics and technology involved in the experiments; (b) enhanced student attitudes toward the lab as a learning environment; and (c) better student facility with the experiment and the equipment involved in it. The work in this project focuses on three contemporary and engaging topic areas that have been the foundation to various student projects in the Bethel University physics department: (1) compressible fluid mechanics, (2) atomic molecular and optical (AMO) physics, and (3) plasmonics and nano-optics. Intellectual Merit: Web-based resources are already available for physics education in a variety of forms including online lectures, applets and online simulations, and web-based homework. Video vignettes are also being developed which provide an online environment that combines narration, real-world video, and analysis tools. The work here differs from these other ongoing projects by emphasizing web-based simulations in which the user interacts with video from advanced laboratory experiments. Consequently, user interactions with the web-based video are designed in a fashion that provide a window into real advanced laboratory experiments and provide a stimulus for learning, creativity, and further engagement in the lab. The participating BU faculty have extensive experience teaching in the advanced laboratory and bring research expertise in the areas of fluid mechanics, AMO physics, and plasmonics and nano-optics. The collaborators from Rochester Institute of Technology (RIT) have been leaders in the physics education community with their work in interactive video analysis. The analysis software is being developed using best practices of software engineering. Broader Impacts: Activities produced in this project are openly available at ComPADRE.org. Additionally, the software is being made available as open source along with complete documentation, enabling other institutions to build activities based on their own advanced labs and undergraduate research and opening the doors of the advanced laboratory community to a broader audience. The activities from each of the topic areas are to be accessible to adopters and potential adopters in a workshop at the 2014 AAPT conference, and at other conferences and workshops (such as the ALPhA Laboratory Immersions).
