The Tutor Engagement Assistant (TEA): Promoting High-Quality TA-Student Interactions

该项目旨在通过开发一种新的软件工具来支持助教(TA)与学生的互动，从而服务于国家利益。计算机课的班级规模越来越大，导致更多地依赖本科生助教来支持学生学习。许多助教往往只比他们帮助的学生稍有经验。为学习者提供帮助是一个复杂的认知过程，需要：1)理解问题，2)调试学习者不正确的解决方案，3)识别概念空白，4)确定如何最好地填补概念空白。该项目的目标是开发导师参与助理(TEA)系统。TEA系统将帮助本科生助教快速调试学生代码，并构建个性化的问题集，以构建他们与学生的互动。这个项目希望在全国范围内的计算机课程中带来更有效和更有教育效果的助教帮助，并应该对学习科学、人机交互和计算机教育的研究做出贡献。这项工作基于两个理论：社会建构主义和认知负荷。它借鉴了ICAP框架，该框架将认知参与与积极的学习结果联系起来。该项目将探索茶在时间上对任务、帮助类型、认知负荷、学习者参与度、自我效能、求助态度、求助行为和学习的影响。研究计划包括三个阶段：1)基线数据收集，2)形成性评估，3)TEA部署。该项目将导致1)通过观察研究详细了解教师与学生的互动，2)通过自动生成的更正的指导演练帮助教师快速了解学生错误的新方法，3)为学生识别和管理个性化问题集的技术，以及4)评估个性化问题集对教师与学生互动和学生学习的质量的影响。NSF IUSE：EHR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 developing a new software tool to support teaching assistant (TA)-student interactions. Increasing class sizes in computing have led to a greater reliance on undergraduate TAs to support student learning. Many TAs are often only slightly more experienced than the students they help. Providing help to a learner is a complex cognitive process that requires: 1) Understanding the problem, 2) Debugging the learner's incorrect solution, 3) Identifying conceptual gaps, and 4) Determining how to best fill the conceptual gaps. The goal of this project is the development of the Tutor Engagement Assistant (TEA) system. The TEA system will help undergraduate TAs to quickly debug student code and construct personalized problem sets to structure their interactions with students. This project hopes to lead to more efficient and educationally effective TA help in computing courses nationwide, and should contribute to research in the learning sciences, HCI, and computing education. This work is based on two theories: social constructionism and cognitive load. It draws on the ICAP framework that links cognitive engagement with active learning outcomes. The project will explore the impact of TEA on time on task, type of help, cognitive load, learner engagement, self-efficacy, attitude towards help, help-seeking behavior, and learning. The research plan consists of three phases: 1) baseline data collection, 2) formative evaluation, and 3) TEA deployment. The project will lead to 1) a detailed understanding of tutor-student interactions through observation studies, 2) new approaches to help tutors quickly understand student errors via a guided walkthrough of automatically generated corrections, 3) techniques for identifying and curating personalized problem sets for students, and 4) an evaluation of the impact of personalized problem sets on the quality of tutor-student interactions and student learning. The NSF IUSE: EHR 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.
