Self-Paced Lectures With as-Needed Answers and Live Interactions

该项目旨在通过寻求同步和异步教学方法之间的最佳平衡来服务于国家利益，从而产生一种平衡的方法，潜在地使具有不同需求和学习速度的学习者能够更有效地学习。该研究项目旨在解决由背景和内容获得率不同的学生造成的共同教育挑战。通过为学生提供现场课程的好处(例如，实时讨论和从彼此的问题中学习)以及他们自己观看视频的好处(例如，暂停、加速、倒带)，可以满足不同的学习需求。这一方法特别适用于入门和继续教育课程，这些课程包括背景知识和准备水平差异很大的学生。学生可以使用预先录制的讲座视频，其中包含以前提出的问题的存储库，此外，还使用互动对话模块直接与教师实时联系。该方法将在两所大学和两种不同的课程类型(传统讲授和翻转课堂)中进行评估，包括高级课程和研究生水平的触觉与控制课程。将收集关于学生利用率、表现、参与度、理解力和学习效率的数据。用于数据收集的机制包括网站访问日志、调查和课堂表现。调查和学生焦点小组访谈将被用来了解学生对学习环境的看法。此外，课程讲师还将接受采访，以了解他们是如何将这种方法融入到课程中的。NSF IUSE：EDU计划支持研究和开发项目，以提高所有学生的STEM教育的有效性。通过参与的学生学习路径，该计划支持有前景的实践和工具的创建、探索和实施。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This project aims to serve the national interest by seeking an optimal trade-off between synchronous and asynchronous instructional delivery methods resulting in a balanced approach that could potentially enable learners with different needs and learning paces to learn more effectively. The research project aims to address common educational challenges caused by students having disparate backgrounds and content acquisition rates. By providing students with the benefits of a live class (e.g. real-time discussions and learning from each other's questions) as well as the benefits of watching a video on their own (e.g. pause, speed up, rewind), different learning needs can be accommodated. The approach is particularly relevant to introductory and continuing education courses that include students having highly contrasted levels of background knowledge and preparation.Pre-recorded lecture videos that feature a repository of previously asked questions are made available to students, additionally, an interactive dialogue module is used to connect directly with the instructor in real-time. The approach will be evaluated at two universities and in two different course types (traditional lecture and flipped classroom) in senior and graduate level courses in Haptics and Controls. Data will be collected on student utilization, performance, engagement, understanding and learning efficiency. Mechanisms to be used for data collection include website access logs, surveys, and performance in the class. Surveys and student focus group interviews will be employed to understand how students perceive the learning environment. Also, course instructors will be interviewed to understand how they are incorporating the approach into their courses. The NSF IUSE: EDU Program supports research and development projects to improve the effectiveness of STEM education for all students. Through the Engaged Student Learning track, the program supports the creation, exploration, and implementation of promising practices and tools.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.
