摘要

本研究之目的是在探討視障高中生的經驗，了解其網路資訊搜尋的行為，尤其是當他們透過螢幕閱讀軟體導盲鼠，在網際網路上搜尋資訊，用來回答以事實為基礎的課業問題。六位啟明學校高中一年級至三年級的學生為研究對象。本研究使用立意取樣，根據學生使用螢幕閱讀軟體導盲鼠及網路資訊搜尋經驗做為選取方式。本研究採用個案研究法進行質性研究，對學生的網路資訊搜尋行為做詳細描述，並探究他們對於網路可及性和可用性問題的理解。藉由檢索作業前訪談、檢索作業觀察、網路資料搜尋作業檢索歷程及完成檢索作業後訪談四種方法蒐集資料，謄寫紀錄後進行資料分析。經資料分析後，歸納出三項結果：在行動及認知方面的網路資訊搜尋行為、網路可及性和可用性問題及網路資訊搜尋遇到挑戰採用的對策。依據研究結果，本研究亦對未來的研究提出建議。

The purpose of the study was to provide comprehensive insight into high school students' experiences by examining their information search behaviors on the Web through G-mouse screen readers to answer academic fact-based questions. Six participants were high school students from grades 10 through 12 at a school for the visually impaired. They were selected by using purposeful sampling based on their use of G-mouse screen reader and experience in searching information on the Web. Qualitative research methods and case study design were used to provide detailed descriptions of participants' information searching behaviors and to learn about their understanding of accessibility and usability issues. Four sources of data collected from pre-task interviews, observations, online information search task sessions, and post-task interviews were transcribed and analyzed. This study had three main findings: the information search behaviors regarding actions and the cognition, accessibility and usability problems, and strategies to overcome challenges. Suggestions for future research were also discussed.
