本研究採用問卷調查法了解完全中學學生使用圖書館之期望與實際感受之服務品質，藉以瞭解學生對圖書館的滿意度，作為圖書館改善服務之參考。研究首先透過文獻分析，參考圖書館的服務品質評量工具LibQUAL+，並研究國內針對高中職圖書館之相關理論，修改發展出適合高中生與國中生之圖書館服務品質評量指標，並經與學校圖書館人員及使用者進行共三場焦點團體訪談後修正指標並進一步發展為問卷。本問卷以抽樣之台中市四所完全中學學生為實證研究對象，共發出1,142份問卷，回收1,138份，回收率高達99.64％，其中有效問卷1,133份。本服務品質評量問卷共分為「空間環境」、「館藏資源與利用」、「圖書館服務」及「圖書館教育與推廣」等四大構面，共有29項指標，並採用期望服務品質及感受服務品質兩種滿意度評分差距。 本論文研究結果顯示：（一）完全中學學生期待圖書館有更豐富的館藏及提供電子資源。(二)學生到館頻率每週少於一次的高達57.8％，顯示完全中學圖書館的利用率偏低。（三）學生對圖書館感受之服務品質平均值大都在3.5以上，顯示學生對圖書館的服務大致可接受，但均未達優質服務。國中生及高中生均對「圖書館所在便利性」最不滿意。（四）不同性別對圖書館感受服務品質差異性較小，國中生及高中生對圖書館感受服務品質差異性大；國中生感受的服務品質大都高於高中生。（五）完全中學圖書館需針對國中生及高中生提出不同的服務策略。 根據上述研究結果，本論文提出以下建議：(一)運用圖書館服務品質評量加強圖書館評鑑，做為圖書館經營管理之參考。（二）加強推展圖書館利用教育，發揮圖書館功能。（三）擴充圖書館編制提升專業形象，並擴大服務範圍。（四）提昇圖書館軟硬體設備，發揮圖書館資訊服務的功能。 / This study uses the method of Questionnaire to measure the expectations and degrees of satisfaction of comprehensive high school students toward libraries. Using the method of literature review, also taking reference from Library Service Quality Assessment LibQUAL+ and relevant theories concerning high school or professional high school libraries, this study comes up with a revised index of service quality assessment suitable for junior and senior school students. After conducting three focus group interviews with school librarians and users, the researcher then revises the above-mentioned index and transformed it into a Questionnaire. This study, using students from four comprehensive high schools in Taichung City as subjects of empirical studies, issued 1,142 questionnaires, among which 1,138 were returned (the return rate was as high as 99.64%), and effective ones amounted to 1,132.The questionnaire consists of four aspects: space and environment, library resources and usages, library services, and librarian education and promotion. It includes 29 indicators, and is rated by the expected and perceived service qualities. The study shows the following results: 1.Comprehensive high school students look forward to more comprehensive library resources as well as resources in electronic forms. 2.The percentage of students visiting libraries less than once in a week is as high as 57.8%, meaning the usage rate for comprehensive high school libraries is low. 3.The perceived quality for library service, on average, is generally above 3.5 points in a score ranging from 1-5, but not reaching the expected service qualities. Such result manifests that students find the library service mostly acceptable, but not preferable. Both junior and senior high students find ‘the accessibility of libraries’ most unacceptable. 4.Gender has relatively little effect on the difference of perceived quality of service, whereas there’s a big gap between junior and senior high school students. Junior high students tend to score higher than senior high students on perceived service quality. 5.It is imperative for comprehensive high school libraries to provide different service strategies for junior and senior high school students. Based on the result of the above study, the thesis suggests the following: 1.Libraries should use service quality assessment as a way to enhance their evaluation, whose result should be taken as managerial reference. 2.It is imperative to strengthen the promotion of the usage of libraries. 3.It is imperative to enlarge the organization scale of libraries so as to promote professional image and to enlarge service range. 4.It is imperative to upgrade soft, as well as hardware equipment of libraries to enhance information service of libraries.
