摘要
[目的/意义]视频平台成为互联网时代新的知识学习场景,在这种场景下,搜索交互过程可以被看作自我调节学习过程。着重研究自我调节学习情境下不同的任务类型以及学习认知策略对视频类搜索行为的影响,以补充交互式信息检索领域在学习情境下视频类搜索行为的研究。[方法/过程]选择两种任务类型:事实型和技能型,认知策略依据自我调节学习框架分为复述、阐述、组织和批判性思维四种类型。研究采用实验法,以哔哩哔哩视频网站作为测试系统,借用已有的测量框架,基于实验数据探究不同学习认知策略的用户在执行不同类型任务时行为特征以及搜索效果的差异。[结果/结论]发现不同任务类型和学习认知策略会对搜索行为和学习效果产生影响,在多个指标上表现出显著差异,结合任务和认知策略特征进行分析和总结,为视频类搜索平台在学习情境下的系统使用提出了改进建议,对此类搜索平台的改善、提升用户搜索体验和学习效率具有积极意义。
[Purpose/significance]In the Internet era,video platforms have become a new knowledge learning scenario.In this scenario,the search interaction process can be seen as a self-regulated learning process.This paper focuses on the effects of different task types and learning cognitive strategies on video-based search behavior in self-regulated learning contexts to complement research in the field of interactive information retrieval on video-based search behavior in learning contexts.[Method/process]In this paper,we chose two types of tasks:factual and skill-based.And cognitive strategies were classified into four types based on the self-regulated learning framework:rehearsal,elaboration,organization and critical thinking.The study adopted an experimental approach,using the Bilibili video site as a test system,and borrowed an existing measurement framework to explore the differences in behavioral characteristics and search effects of users with different learning cognitive strategies when performing different types of tasks based on experimental data.[Result/conclusion]This paper finds that different task types and learning cognitive strategies affect search behavior and learning effectiveness,showing significant differences in several indicators.The analysis and conclusion combined with task and cognitive strategy characteristics suggest improvements for the system use of video-based search platforms in learning contexts,which have positive implications for the improvement of such search platforms and the enhancement of user search experience and learning efficiency.
