Exploring the interplay between question-answering systems and communication with instructors in facilitating learning
研究发现在大学课程中单独使用问答系统并不能改善学习过程或结果，但能显著增强与教师沟通的正面效果，为教育技术应用提供指导。
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.
