摘要： 本文基于不同認知水平下的三項與健康相關(guān)的學(xué)習型搜索任務(wù)，將知識捕獲、即時學(xué)習效果和持續(xù)學(xué)習效果作為不同階段的學(xué)習效果指標，利用問卷、思維導(dǎo)圖和錄屏數(shù)據(jù)，研究搜索與學(xué)習之間的相關(guān)關(guān)系。研究發(fā)現(xiàn)：①健康信息素養(yǎng)對知識捕獲有顯著的正向作用，先驗知識發(fā)揮了負向調(diào)節(jié)效應(yīng)；②任務(wù)復(fù)雜度對即時學(xué)習效果有顯著的負向作用，先驗知識發(fā)揮了遮掩效應(yīng)；③任務(wù)復(fù)雜度和知識捕獲對持續(xù)學(xué)習效果有顯著的負向作用，知識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)習效果間的關(guān)系。學(xué)習型搜索在學(xué)習鏈的不同階段產(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)習發(fā)生過程。

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
