研究結果發現,電腦自我效能是決定使用網路教學的重要因素,性別為權力行使在網路教學很重要的使用者的決定因素 本論文所採用的研究模式還不夠完善。因此,若要發掘淡江大學選用網路教學背後真正的原因,仍有待未來更進一步的研究。 The present study planed to identify the role of the exercise of authority in faculty decision to adopt Web-based instruction at Tamkang University. The proposed model of the study was composed by six groups of variables as independent variables: computer self-efficacy, internet self-efficacy, locus of control, exercise of authority, demographic data (age, rank, gender) and computer-related variables (computer experience, internet experience and weekly internet usage) and two dependent variables: adoption of Web-based instruction and perceived importance of authority in Web-based instruction. A broad related literature review was made to build the framework of the study and to develop research hypotheses. Eight principal hypotheses were developed to measure relationships between the above independent variables with the adoption of Web-based instruction and with the perceived importance of authority in Web-based instruction. The participants of the survey were full-time faculty in each of the eight colleges at Tamkang University. A questionnaire of 59 items was sent to 256 faculty members (35% of total number of faculty) and 122 responses were collected. Three discriminant analyses were performed to measure the predictability of our model. The first one was to discriminate the current adopters from the current non-adopters of Web-based instruction; the second discriminant analysis was for future adopters from future non-adopters of Web-based instruction and the last one for those who perceived authority as important in Web-based instruction from those who were not. The results show computer self-efficacy as discriminator for Web-based instruction adoption and gender as discriminator for perceived importance of authority in Web-based instruction. But the model used was less desirable and future research would be needed if we intend to find the real reasons behind the adoption of Web-based instruction at Tamkang University.
