整合TAM與TPB觀點探討大學生遠距學習平台使用意圖-兼論COVID-19 認知風險的干擾效果

因COVID-19高傳播率，對社會、產業與經濟所帶來的影響，生活與學習方式的劇烈改變，在減少傳播前提下，台灣各級學校不得不暫時封閉校門禁止學生到校學習。本研究以COVID-19疫情影響為背景，探討大學生採用遠距學習平台後的學習成效，並整合TAM與TPB模式探討學習者採用遠距學習平台的過程，欲探究「認知有用性」和「認知易用性」，對學習者的「使用態度」與「使用意圖」之間可能產生的影響；接著探討學習者在COVID-19疫情的認知風險下，是否會增強其使用遠距學習平台的意圖。本研究主要以「國立臺中科技大學」有使用線上遠距學習平台之在校學生為主要研究調查對象，採便利抽樣方式，並採用網路問卷調查回收問卷。有效回收問卷585份，有效問卷回收率為98.31%。結果分析顯示，認知有用性對使用態度具有顯著正向影響，而認知易用性對使用態度具有顯著正向影響。此外，使用態度對使用意圖具有顯著正向影響，主觀規範對使用意圖具有顯著正向影響，認知行為控制對使用意圖具有顯著正向影響。最後，進一步探討認知風險與使用態度、主觀規範及認知行為控制與干擾變數認知風險的交互作用，結果分析顯示，認知風險對使用態度與使用意圖間關係，以及認知行為控制與使用意圖間關係皆具正向調節效果，此外，認知風險對主觀規範與使用意圖間關係則呈現負向調節效果。

Due to the high infectious rate of COVID-19, it has brought a huge impact on society, industry and economy, and even caused major changes in life. Consequently, the way of living and learning has changed accordingly. In order to reduce the spread of the pandemic, schools at all levels in Taiwan had to be temporarily closed and students could no longer attend school for learning. In the context of the impact of the COVID-19 pandemic, this study explored the learning outcomes of college students after using distance learning platforms, and integrated the TAM and TPB models to explore the learners’ process of using distance learning platforms. This study probed into the possible impacts of “perceived usefulness” and “perceived ease of use” on the “use attitude” and “use intention” of learners. It also discussed whether learners' intention to use distance learning platforms would be enhanced by the perceived risk of the COVID-19 epidemic. This study focused on the students using online distance learning platforms in the National Taichung University of Science and Technology as the main research objects. Convenience sampling was used in this study, and the questionnaires were collected by means of online questionnaire. A total of 585 valid questionnaires were recovered, with a valid return rate of 98.31%. The analysis results show that “perceived usefulness” has a significant positive impact on “use attitude”, while “perceived ease of use” has a significant positive impact on “use attitude”. In addition, “use attitude” has a significant positive impact on “use intention”, “subjective norm” has a significant positive impact on “use intention”, and “cognitive behavior control” has a significant positive impact on “use intention”. Finally, this study further explored the interaction between “perceived risk” and “use attitude”, “subjective norm” and “cognitive behavior control” and the disturbance variable “perceived risk”. The analysis of the research results show that “perceived risk” has a positive moderating effect on the relationship between “use attitude” and “use intention”, as well as “cognitive behavior control” and “use intention. Furthermore, “perceived risk” has a negative moderating effect on “subjective norm” and “use intention”
