本研究使用眼动追踪技术来追踪学生在网络上搜索信息时的眼动。本研究的研究问题是：不同搜寻绩效水平的学生在搜寻网路资讯时，是否有不同的视觉注意力分布？如果是，高性能搜索者和低性能搜索者的模式是什么？”澳门的14名大学生被邀请在网上搜索一个问题的答案：“你用自来水清洗玻璃后，为什么玻璃表面总是有一些水滴残留？”使用Tobii Pro X2-30远程眼动仪进行数据收集。两名学生的最高和最低的搜索任务得分被选中进行比较，在他们的在线搜索行为和眼动模式。表现好的学生在修改搜索查询、阅读和评估所选网页中信息的相关性方面做得更多。搜索模式显示，高性能的学生往往更频繁地切换之间的搜索查询框和搜索结果页面，而低性能的学生往往切换之间的搜索结果和选定的网页。这意味着高表现的学生通过重新访问和修改搜索查询来提高搜索结果的质量。
This study used eye-tracking technology to track students’ eye movements while searching information on the web. The research question guiding this study was “Do students with different search performance levels have different visual attention distributions while searching information online? If yes, what are the patterns for high and low performing searchers?” 14 university students in Macau were invited to search an answer online for the question: “After you clean a glass with tap water, why are there always some water drops remaining in the glass surface?” A Tobii Pro X2-30 remote eye tracker was used for data collection. Two students with the highest and lowest search task scores were selected for comparisons in their online search behavior and eye-movement patterns. The high-performing student worked more in revising search queries, and reading and assessing the information in the selected webpages for its relevance. Search patterns showed that the high-performing student tended to switch more frequently between search query box and search result page whereas the low-performing student tended to switch between the search result and selected web page. This implied that the high-performing student was more metacognitively engaged by revisiting and revising search queries to improve the quality of search results.
