[[alternative]]To Explore Factors of Continually Using Teachers’ In-service Education Website by Using TAM--An Example of Elementary School Teachers in Chia-Yi County

[[abstract]] 為了配合國家教育改革政策，有效統整教師在職進修資源，教育部特於92年初成立北、中、南、東等區域性教師在職進修中心。經過幾年來的努力，全國教師在職進修網之涵蓋範圍已大致齊全。但此網站涵蓋範圍雖廣，其網站品質是否有待加強？又使用者對此網站是否滿意？有鑑於此因，本研究依據科技接受模式之理論架構，以知覺有用和知覺易用做為近因變項，並以結構性認知做為中介變項，以探討影響教師持續使用此系統的意願因素。本研究採用問卷調查與統計分析進行，研究對象為嘉義縣使用全國教師在職進修網之國小教師。發放正式問卷150份，全部回收，有效問卷128份，並以SPSS及Visual PLS統計軟體進行資料分析。研究結果發現，影響持續使用行為意願的最重要因素是知覺易用性，其次是結構性認知和知覺有用性。值得注意的是，知覺易用性及知覺有用性構面裡影響層面最強的均為網站品質構面，意味著良好的網站設計是影響使用者持續使用的最大因素；而知覺易用性則是影響結構性認知構面中最強的變項，也說明親切的操作介面重要性極高。[[abstract]] In order to cope with national education policy and to integrate teachers’ in-service training resources effectively, the Ministry of Education especially set up regional teacher in-service training centers in North, Center, South and East at the beginning of 2004. After several years of efforts, the Teachers’ In-service Education Website’s coverage has been substantially completed. Does the quality of website need to be strengthened though this website covers a wide range? Are the users satisfied with this website? In view of this reason, the theoretical framework of this study is based on Technology Acceptance Model (TAM). We use Perceived Usefulness (PU) and Perceived Ease of Use (PEU) as external variables and Perceived Structure (PS) for intervening variables to explore the possible factors of teachers' Behavioral Intention (BI) to continue using the system. Questionnaires and statistical analysis are used for this research. Subjects of research are elementary school teachers who use the Teachers’ In-service Education Website in Chia-Yi County. Total of 150 copies were sent, all copies were collected and effective questionnaires are 128 copies. We analyzed the data by applying the SPSS and Visual PLS statistical software. The results show that PEU is the most important factor which affects teachers’ BI to use Teachers’ In-service Education Website, while PS is the second, and PU is the third. Exactly as it might be expected, PEU and PU are influenced strongly by the system quality, which means good design of website is the biggest factor of affecting users’ intention in continuous using. Furthermore, PEU is the biggest variable to affect PS, which means friendly operating interface is very important
