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

该项目旨在为国家利益服务，寻求同步和异步教学方法之间的最佳平衡，从而形成一种平衡的方法，可能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具有不同背景和内容获取率的学生造成的常见教育挑战。通过为学生提供实时课堂的好处（例如实时讨论和从彼此的问题中学习）以及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。该方法特别适用于入门和继续教育课程，包括学生具有高度对比的背景知识和准备水平。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，此外，交互式对话模块用于直接与讲师实时连接。该方法将在两所大学进行评估，并在两种不同的课程类型（传统讲座和翻转课堂）的高级和研究生水平的触觉和控制课程。将收集有关学生利用率、表现、参与度、理解和学习效率的数据。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如何看待学习环境。此外，课程讲师将接受采访，以了解他们是如何将这种方法纳入他们的课程。NSF IUSE：EDU计划支持研究和开发项目，以提高所有学生STEM教育的有效性。该奖项反映了NSF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 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.
