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教学助理（TA）-学生互动，从而为国家利益服务。计算类规模的增加导致了对本科助教的依赖，以支持学生的学习。许多助教通常只比他们帮助的学生稍微有经验。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）纠正学习者的错误解决方案，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。该项目希望能在全国范围内为计算课程提供更有效和更有效的TA帮助，并应有助于学习科学，HCI和计算教育的研究。本研究基于两个理论：社会建构主义和认知负荷理论。它借鉴了ICAP框架，将认知参与与积极的学习成果联系起来。该项目将探讨TEA对任务时间，帮助类型，认知负荷，学习者参与，自我效能，对帮助的态度，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导师与学生的互动，2）通过自动生成更正的指导演练帮助导师快速了解学生错误的新方法，3）为学生识别和策划个性化问题集的技术，以及4）评估个性化问题集对师生互动和学生学习质量的影响。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 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.
