Collaborative Research: Interactive Video-Enhanced Tutorials on Problem Solving in Physics

罗彻斯特理工学院和辛辛那提大学的这一合作项目旨在增加STEM专业毕业生的数量，使美国能够保持强大的劳动力队伍以保持全球竞争力。在大学的前两年留住更多的STEM专业学生尤为重要。本项目将为物理入门课程创建、测试、评估并传播一套互动式在线教程。这些教程旨在帮助学生培养解决复杂问题所需的技能，同时为学生提供早期的积极体验，以建立他们的信心和毅力。基于多媒体学习原理和对人类学习和记忆的研究，每个教程将提供不同数量和类型的支持，与个别学生的需求保持一致。支持将通过（在线）迷你讲座、提示、提示或导师（出现在视频中的真人）的鼓励来提供。遇到困难的学生将得到更多的指导，而遇到困难较少的学生将能够以更快的速度浏览教程。这个过程的目的是类似于有一个现场导师的帮助和指导。该项目的总体目标是通过使用在线教程来教学解决问题，以改善所有学生的物理教学，并通过研究教程的使用为物理教育研究做出贡献。为了实现这些目标，项目团队确定了以下目标：(1)创建一套30个在线交互式视频增强教程（IVETs）。(2)通过ComPADRE物理天文学教育资源数字图书馆（https://www.compadre.org/）传播IVETs。(3)评估至少10个IVETs的有效性，并比较两所合作大学IVETs的有效性。(4)传播研究成果。IVETs将是一个创新的资源，可以支持物理入门课程。此外，对学生与IVETs互动的研究可以增加对优化学生使用在线作业系统的教学策略的理解。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

This collaborative project at the Rochester Institute of Technology and the University of Cincinnati aims to increase the number of students who graduate in STEM, so that the United States can maintain a strong workforce for global competitiveness. Retaining more students in STEM majors during the first two years of college is especially critical. This project will create, test, evaluate, and disseminate a set of interactive online tutorials for introductory physics classes. These tutorials will be designed to help students develop the skills necessary for solving complex problems, while giving students early, positive experiences that will build their confidence and persistence. Based on multimedia learning principles and research on human learning and memory, each tutorial will provide varying amounts and types of support, aligned with individual student needs. The support will be delivered through (online) mini-lectures, hints, tips, or encouragement by a tutor (a real person who appears in a video). Students who struggle more will receive more guidance, and students who struggle less will be able to navigate through the tutorial at a faster pace. The process is intended to be similar to having a live tutor for help and guidance.The project's overarching goals are to improve physics instruction for all students by using online tutorials for teaching problem solving, and to contribute to physics education research by studying the use of the tutorials. To achieve these goals, the project team has identified the following objectives: (1) Create a set of 30 online Interactive Video-Enhanced Tutorials (IVETs). (2) Disseminate the IVETs through the ComPADRE Digital Library of educational resources in physics and astronomy (https://www.compadre.org/). (3) Evaluate the effectiveness of at least ten of the IVETs, and compare the effectiveness of IVETs at the two collaborating universities. (4) Disseminate the results of the research. The IVETs will be an innovative resource that can support introductory physics courses. In addition, the research on students' interactions with the IVETs can increase understanding of instructional strategies that optimize students' use of online homework systems.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
