| 摘 要： | 目的/意义]针对复杂多面的探索式搜索情境下高校学生用户的搜索元认知测评问题,设计一个可行有效的测评问卷。通过设定4类不同的探索式搜索情境,对被试在各规定情境下的元认知表现进行多维度分析与评价。方法/过程]运用元认知理论设计"探索式搜索元认知测评问卷",在预试环节对该问卷进行信效度检验。在正式测评环节,通过开展搜索测验的方式组织60名高校学生被试进行探索式任务搜索和问卷调查,使用"Camtasia Studio"录制被试的搜索画面,并进行事后访谈。综合问卷调查数据、搜索行为视频与访谈内容,分析在4种不同探索式搜索情境下被试对"搜索任务与个体认知"的认知、对"搜索过程监控"的认知、对"搜索过程与评估反思"的认知情况。结果/结论]该问卷具有良好的内部一致性信度和结构效度,可作为测评高校学生用户探索式搜索元认知水平（或表现）的有效工具。根据维度数据分析结果,高校学生用户对于决策型问题（评估决策搜索）和研究型问题（知识获取搜索）的个体能力认知、任务理解能力、搜索障碍监控等能力相对匮乏,针对该分析结果从高校信息素养教育、搜商能力的培养和网络搜索系统人机交互功能设计三个方面,提出改善高校学生用户探索式搜索能力的思考和建议。

| Abstract: | Purpose/significance] This paper develops a feasible and effective questionnaire for the metacognitive measurement issues of university student in multi-faceted and exploratory search situation. It designs four different types of exploratory search situation, and conducts multi-dimensional analysis and evaluation of the subjects' metacognitive performance under each prescribed situation. Method/process] In this paper, we used metacognitive theory to design"exploratory search meta-cognitive assessment questionnaire", and conducted its reliability and validity test in pilot study. Besides, by conducting a search test, we selected 60 university students to conduct exploratory search tasks and gave them a questionnaire in the formal evaluation process. In this process,we also used Camtasia Studio to record the search images and conducted a post-interview. Through the survey data, search behavior videos and interviews, we analysed users' cognition of search tasks and self-cognitive, search process monitoring and search process evaluation in four different types of exploratory search situation. Result/conclusion] On the one hand, the questionnaire has good coefficient of internal consistency reliability and validity, and it can be used as an effective tool to measure university students' exploratory search metacognitive level (or performance). On the other hand, according to the dimensional data analysis result, university students' self-cognitive, tasks comprehension and search obstacle monitoring capability are relatively less when faced with decision type problem (evaluation decision search) and research problem (knowledge acquisition search task). According to the results, we propose suggestions to improve the university students' exploratory search abilities from three aspects-information literacy education, cultivation of SQ and human-computer interaction function of web search system. |
