本研究旨在以科技接受模式爲理論基礎,探討學生「內在學習認知」對「使用行爲意圖」的影響,並發展一個整合性的「電腦輔助教學軟體效益實證權變模式」。爲了驗證此模式的可行性,本研究採用問卷調查,並進行學生使用前後之成績比較分析。本研究的對象爲一所專科學校的學生,共發出370份問卷,有效問卷共351份,有效回收率爲94.9%。由階層迴歸分析結果發現,科技接受模式中的「知覺有用性」、「知覺易用性」、「主觀規範」、「電腦焦慮」與「電腦自我效能」對電腦輔助教學軟體的使用意圖有正向的影響,並進而改善學生的學習效益。另外,比較學生使用前後之成績發現,對電腦輔助教學軟體的練習,每週時數超過3小時以上者(成績進步平均數爲5.02分),與每週時數3小時以下者(成績進步平均數爲2.57分)成效明顯的提高。
By using the Technology Acceptance Model (TAM) as a theoretical foundation, the main purposes of this study were (1) to explore the impact of student's 'internal learning cognition' on the 'behavioral intention to use', (2) to develop an integrated theoretical framework-'the empirical contigent model of the effect of computer instruction assisted software.' In order to verify the feasibility of the model, this study analyzed and compared the data collected by questionnaire survey and the students' results between before and after using computer instruction assisted software. The subjects were the students of one junior college. 370 questionnaires were administered. There were 351 valid questionnaires and the valid returned rate was 94.9%. The stepwise regression was used for statistical analysis. This study found that 'Perceived Usefulness', 'Perceived Ease of Use', 'Subjective Norms', 'Computer Anxiety' and 'Computer Self-Efficacy', of TAM had positive influence on the intention to using computer instruction assisted software, and could improve the students' learning effects. Furthermore, by comparing the students' results between before and after using computer instruction assisted software, this study also found that the students who practiced above 3 hours weekly (with improved scores by 5.02 for average) were significantly higher than the students who practiced less than 3 hours (with improved scores by 2.57 for average).
