Purpose

Question-answering (QA) systems are being increasingly applied in learning contexts. However, the authors’ understanding of the relationship between such tools and traditional QA channels remains limited. Focusing on question-answering learning activities, the current research investigates the effect of QA systems on students' learning processes and outcomes, as well as the interplay between two QA channels, that is, QA systems and communication with instructors.

Design/methodology/approach

The authors designed and implemented a QA system for two university courses, and collected data from questionnaires and system logs that recorded the interaction between students and the system throughout a semester.

Findings

The results show that using a QA system alone does not improve students' learning processes or outcomes. However, the use of a QA system significantly improves the positive effect of instructor communication.

Originality/value

This study contributes to the literature on learning and education technology, and provides practical guidance on how to incorporate QA tools in learning.

探索问答系统与教师沟通在促进学习方面的相互作用

目的

问答 (QA) 系统越来越多地应用于学习环境。然而，作者对此类工具与传统 QA 渠道之间关系的理解仍然有限。目前的研究以问答式学习活动为重点，调查了QA系统对学生学习过程和结果的影响，以及QA系统和与教师沟通两个QA渠道之间的相互作用。

设计/方法/方法

作者为两门大学课程设计并实施了一个 QA 系统，并从问卷和系统日志中收集数据，这些数据记录了整个学期学生与系统之间的交互。

发现

结果表明，单独使用 QA 系统并不能改善学生的学习过程或结果。然而，QA 系统的使用显着提高了教师沟通的积极效果。

原创性/价值

本研究为学习和教育技术的文献做出了贡献，并为如何将 QA 工具纳入学习提供了实用指导。
