摘要： 本文基于不同認(rèn)知水平下的三項(xiàng)與健康相關(guān)的學(xué)習(xí)型搜索任務(wù)，將知識(shí)捕獲、即時(shí)學(xué)習(xí)效果和持續(xù)學(xué)習(xí)效果作為不同階段的學(xué)習(xí)效果指標(biāo)，利用問(wèn)卷、思維導(dǎo)圖和錄屏數(shù)據(jù)，研究搜索與學(xué)習(xí)之間的相關(guān)關(guān)系。研究發(fā)現(xiàn)：①健康信息素養(yǎng)對(duì)知識(shí)捕獲有顯著的正向作用，先驗(yàn)知識(shí)發(fā)揮了負(fù)向調(diào)節(jié)效應(yīng)；②任務(wù)復(fù)雜度對(duì)即時(shí)學(xué)習(xí)效果有顯著的負(fù)向作用，先驗(yàn)知識(shí)發(fā)揮了遮掩效應(yīng)；③任務(wù)復(fù)雜度和知識(shí)捕獲對(duì)持續(xù)學(xué)習(xí)效果有顯著的負(fù)向作用，知識(shí)捕獲的完全中介效應(yīng)改變了健康信息素養(yǎng)和持續(xù)學(xué)習(xí)效果間的關(guān)系。學(xué)習(xí)型搜索在學(xué)習(xí)鏈的不同階段產(chǎn)生了差異化影響，研究結(jié)果有助于深入理解用戶的信息使用行為和學(xué)習(xí)發(fā)生過(guò)程。

Abstract: In this study, knowledge capture, immediate learning performance and continuous learning performance are used as indicators of learning effect at different phases. The relationship between search and learning is studied via questionnaire, mind map and video data collected from participants based on three health-related information tasks at various cognitive levels. It is found that: ①Health information literacy significantly improves knowledge capture, but prior knowledge has a negative moderating effect; ②Task complexity has a strong negative effect on immediate learning performance, and prior knowledge has a masking effect; ③Task complexity and knowledge capture have a significant negative effect on the continuous learning performance. The relationship between health information literacy and continuous learning performance are changed by the knowledge capture which is a full mediation variable. This study finds that learning-related search has a distinct impact in different phases of the learning chain, which is helpful to further understand information utilization and learning process.

Key words: Search as learning (SAL), Knowledge capture, Health information literacy, Learning-related search, Knowledge state change
