【摘要】：当今社会,随着信息的猛速发展和互联网的出现,使人们被不同形式信息包围着。因此,信息素养作为一种定位和识别,并在信息社会可以有效解决问题的能力已经成为许多职业的一项基本要求。伊格尔顿和罗伊(2007)通过实证研究提出了在网络环境下处理信息过程的QUEST模型,即问题、理解、评估、综合和转换策略。同时,幻灯片作为可以承载不同来源信息的理想载体用来测量外语学习者的信息素养能力。基于QUEST模型,本研究旨在探讨外语学习者在网络环境下使用的信息素养策略的使用。具体地说,本研究试图回答以下三个问题:1.外语英语学习者经常使用哪些策略?哪些策略使用较少?2.信息素养策略使用与幻灯片得分之间是否存在相关?具体使用哪些策略与得分之间相关?3.幻灯片得分高分组与低分组之间使用信息素养策略的差异是什么?研究选取57名大学生作为被试。要求被试在网上搜索有关“海平面上升”的信息,然后以“海平面上升”为主题做一份不少于9页的幻灯片,学生使用互联网查找、评价和合成所需要的信息,整个过程在150分钟内完成。依据克兰茨(2003)的“表现评估”,制定幻灯片文件评分标准。评分标准包括四个部分,即完整性、语言、内容和结构,每个部分按照“低-1分”“中等-2分”“高-3分”打分,因此幻灯片文件的总分范围为4分到12分。除此之外,一份基于QUEST模型的调查问卷也由研究者制作用以调查被试的策略使用情况。为了回答以上问题,研究通过四种方法收集数据。首先,被试的信息素养由他们的幻灯片得分来估量。其次,信息素养策略使用情况的数据由问卷收集。另外,被试收集信息的过程由My Screen Recorder这款录制桌面活动的软件来监测,以此作为问卷收集信息素养策略使用情况的补充。最后,在被试完成问卷之后,为了了解他们制作幻灯片时的想法,相应的访谈也会随之展开。这样,信息素养策略的使用结果可以通过分析这些数据而得到。最后,SPSS 20.0被用于通过描述数据、皮尔逊聚居相关和单尾方差分析来分析这些数据。研究结果表明,首先,受试者在定位、评估和使用信息的过程中频繁使用五种策略。具体来说,问题策略和评估策略使用频率较高,输出策略相对较低。第二,受试者使用的信息策略与他们幻灯片总得分不存在显著的相关关系,然而与评分标准中子分数具有显著相关。具体来说,使用评估策略和其子策略(评估网址)与语言方面得分有关;使用评估策略(有目的性的点击网址和标注信息来源)与内容方面得分;将多种信息和研究问题匹配与结构方面得分有关。最后,受试者分别根据其幻灯片的总得分、完整性、语言、内容和结构被分成高、中、低分三组。结果显示,比较总分和五大类策略的使用时,高分组与低分组之间没有明显的差异。但是,当探究子得分和策略使用之间的关系时,差异是明显的。使用评估策略、搜索信息时提出问题、翻译网址和域名、有目的性地点击网址,评估网址、转换主题、访问新网址、尝试新的关键词和改变搜索引擎以获取所需信息方面,两组之间在语言得分上有明显不同。使用翻译网址和域名以及标注信息来源两组在内容得分上有明显不同。操作电脑和将多种信息与研究问题匹配两组在结构得分上有明显不同。本研究的重要意义在于帮助我们更好地理解信息素养,并为该如何教中国英语学习者信息素养进一步指出方向。
[Abstract]:In today's society, with the rapid development of information and the emergence of the Internet, people are surrounded by different forms of information. Therefore, information literacy has become a basic requirement for many occupations as a kind of location and recognition, and the ability to solve problems effectively in the information society. Eagleton and Roy (2007) have made an empirical study. The QUEST model for processing information process in the network environment, namely, problem, understanding, evaluation, synthesis and conversion strategy, is used as an ideal carrier to measure information of different sources. Based on the QUEST model, the purpose of this study is to explore the use of foreign language learners in the network environment. The use of information literacy strategies. Specifically, this study tries to answer the following three questions: what strategies do 1. English learners often use? Which strategies are used less? 2. whether there is a correlation between the use of the 2. Information Literacy Strategy and the slide score? What is the correlation between the strategy and the score? 3. the high score group and the high score score What are the differences in the use of information literacy strategies among the lower groups? The study selected 57 college students as subjects. They asked to search for information on "sea level rise" on the Internet, and then make a slide of no less than 9 pages on the theme of "sea level rise", and students used the Internet to find, evaluate and synthesize the information needed, The whole process is completed within 150 minutes. According to the "performance evaluation" of Krantz (2003), the slide file scoring standard is made. The scoring standard includes four parts, namely, integrity, language, content and structure. Each part is graded according to "low -1" "medium -2" and "high -3", so the total score of the slide file is from 4 to 12. In addition, a questionnaire based on the QUEST model was also made by the researchers to investigate the usage of the subjects. In order to answer the above questions, four methods were used to collect data. First, the information literacy of the subjects was estimated by their slides. Secondly, the data of the information literacy strategy use was collected by the questionnaire. In addition, the process of collecting information by the subjects was monitored by the software of the My Screen Recorder recording desktop activity as a supplement to the use of information literacy strategies. Finally, after the questionnaire was completed, the corresponding interviews would be carried out to understand the idea of making slides. The results of the use of the strategy can be obtained by analyzing these data. Finally, SPSS 20 is used to analyze these data by describing data, Pearson settlement and single tail analysis. The results show that, first, five strategies are frequently used in the process of locating, evaluating and using information. Specifically, problem policy Second, there is no significant correlation between the information strategy used by the subjects and the total score of their slides, but it has a significant correlation with the score standard neutron score. Specifically, the use of the evaluation strategy and its Zi Celve website is related to the language score. Use evaluation strategies (targeted click URLs and annotated sources) and content points; match a variety of information and research problems with the score of the structure. Finally, the subjects are divided into three groups of high, medium, and low scores based on the total score, integrity, language, content and structure of their slides. There is no obvious difference between the high and low groups in the use of five major categories. However, the difference is obvious when exploring the relationship between the score and the use of the strategy. There are significant differences in language scores between the two groups of new keywords and the change of the search engine to obtain the required information. The use of the translation URL and the domain name and the two groups of information sources are distinctly different in the content score. The operating computer and the two groups of information and research problem matching are distinctly different in the structure score. The significance of the research is to help us better understand information literacy and to further indicate the direction of how to teach Chinese EFL learners' information literacy.
