摘　　要：该研究在对青少年信息搜索策略的研究成果梳理基础上,探讨了内隐策略与外显策略对网络学习绩效的影响,提出了引导学生正确查找网络资源的方法。该实证研究发现:内隐策略与外显策略的相关性因子较少,二者是相互独立的;内隐策略的"选择主要观点"因子与融合性指标有显著正相关性,"评价因子"与健全性和总绩效有显著正相关性;外显策略的"浏览结果时间、略读时间因子"与搜索结果存在显著负相关性,"采用网页数目和精读时间因子"与搜索结果存在显著正相关;多元回归分析结果表明,精读时间和评价是显著预测搜索结果的健全性、总绩效的变量,精读时间和采用网页数目是显著预测丰富性和融合性的变量。Based on the adolescents＇ information searching strategies research review, the study discusses implicit and explicit strategies impacting on web-based learning performance, and proposes the methods of guiding students to find information resources. The empirical study shows that implicit and explicit strategies are independent of each other, since few factors are correlated with statistical significance. Selecting main ideas factor of implicit strategies has significantly positive correlations with the Integration indicator, and Evaluation factor has significantly positive correlations with the outcomes of soundness and total performance. Explicit strategies＇ browsing results time and skimming time factors have significantly negative correlations with the searching outcomes. Number of adopting web pages and detailed reading time factors have significantly positive correlations with the searching outcomes. Multiple regression analysis results show that detailed reading time and evaluation factors can significantly explain the outcomes of soundness and total performance, detailed reading time and number of adopting web pages factors can significantly predict the outcome of abundance and integration. 5 tabs. 21 refs.
