本研究係根據Davis(1989)提出的科技接受模式為理論基礎,主要目的為探究國中教師使用電子教科書時,其外部變數和認知有用性、認知易用性對電子教科書之認知與使用意願的相互關係。本研究採用問卷調查法進行研究,以高雄市的國中教師為研究對象,採隨機抽樣方式進行,總計發放問卷500份,有效樣本數426份,所得資料以平均數、標準差、t檢定、ANOVA單因子變異數分析及皮爾森積差相關係數等統計方法加以處理。本研究獲得結論:「系統特質」對「認知有用性」有中度正相關。「風險性認知」對「認知有用性」有低度負相關。「環境因素」對「認知有用性」有中度正相關。「系統特質」對「認知易用性」有中度正相關。「風險性認知」對「認知易用性」有低度負相關。「環境因素」對「認知易用性」有中度正相關。國中教師使用電子教科書之「認知有用性」對「認知易用性」有中度正相關。國中教師使用電子教科書之「認知有用性」對「使用意願」有中度正相關。國中教師使用電子教科書之「認知易用性」對「使用意願」有中度正相關。
This study is based on the technology acceptance model that Davis (1989) proposed. The primary purpose of this study is to explore junior high school teachers' behavior pattern of using electronic textbooks; mainly the relationships among the external variables, perceived usefulness, perceived ease of use, and intention to use.This study used random sampling questionnaire survey method targeted at junior high school teachers in Kaoshiung City. Statistic methods included average, standard deviation, t-test, ANOVA and pearson product-moment correlation coefficient were used to analyze the 426 valid samples. The results are as followed:System quality has a moderate positive correlation to perceived usefulness.Perceived risk has a low negative correlation to perceived usefulness.Envirnmental factor has a moderate positive correlation to perceived usefulness.System quality has a moderate positive correlation to perceived ease of use.Perceived risk has a low negative correlation to perceived ease of use.Envirnmental factor has a moderate positive correlation to perceived ease of use. The perceived usefulness of junior high school teachers using electronic textbooks has a moderate positive correlation to perceived ease of use .The perceived usefulness of junior high school teachers using electronic textbooks has a moderate positive correlation to behavioral intention to use .The perceived ease of use of junior high school teachers using electronic textbooks has a moderate positive correlation to behavioral intention to use.
