自主学习情境下用户信息搜寻行为的实证研究

An Empirical Study on Information Searching Behaviors of Autonomous Learning

采用实验法针对大学生用户设置真实的自主学习任务,通过日志分析探寻用户的信息搜寻行为模式特征,并比较不同信息搜寻行为所导致的学习效果。结果表明,在自主学习情境下,用户的主要信息搜寻行为特征为:(1)信息源选择单一;(2)检索式重构次数少;(3)较少浏览和下载排名靠后的检索结果。此外,不同搜寻模式下学习效果具有差异。本文丰富了信息搜寻行为的研究情境,且对学生、教师和系统设计者等都具有一定的实践意义和实践启示。

This paper adopted the experimental method to set up the real autonomous learning task for university students,explored the characteristics of user information search patterns through log analysis,and compared the learning effects caused by different information search behaviors.The results showed that the characteristics of information searching behaviors of autonomous learners are:(1)limited and inadequately information sources;(2)few or no query reconstruction even in a relatively long period;(3)ignoring results with low ranking or less downloading numbers.In addition,different information searching patterns lead to different effects.This paper enriches the research context of information search behavior and has practical significance and practical implications for students,teachers,and system designers.
