3. Research Methodology
This paper aims to establish a combined TAM-SET model to predict learners’ intentions to continuously use BL. After we identified the key contributing constructs and analyzed the relationships among them, we proposed how to enhance learners’ enthusiasm and interest in BL. A survey was adopted in this empirical study to test the hypotheses among these constructs. The subjects of this study were undergraduates from Huaqiao University who experienced using the BL mode for at least a total of one year. The courses offered in Huaqiao University can be divided into public courses (including compulsory courses and elective courses), professional basic courses, and professional elective courses. Most of the courses are available on MOOC platforms, which offer abundant online resources for blended teaching and learning practices. Students can directly use these existing MOOCs to complete online learning, and teachers can design classroom discussions and interactive exchanges based on MOOC resources. A total of 472 students responded to the online questionnaires, and 461 valid responses were included in the analysis. The data were then analyzed using IBM SPSS Statistics (Chicago, IL, USA) 24.0 and Amos (Chicago, IL, USA) 21.0. The reliability, the convergent and discriminant validity, the goodness-of-fit, and the truth of the hypothesis were tested. The scale compilation involved two main processes. First, the contributing constructs of the model were sorted out based on the existing literature [ 36 – 44 ]. Then, 22 students who participated in BL for at least one year were selected as interviewees to explore possible constructs for the scale. By combining the findings of the two processes, seven factors were identified that might affect blended learning adoption from the learners’ perspective, namely course quality (CQ), technological support (TS), perceived usefulness (PU), perceived ease of use (PEOU), satisfaction (SA), self-efficacy (SE), and behavioral intentions (BI). Most of the items under each construct were adapted from well-tested scales, and some new items were designed according to the characteristics of BL used in the present study. To further improve the validity of the questions, the draft of the questionnaire was sent to experts for their suggestions and improvement. After some amendments, the final questionnaire contained 7 constructs with 26 sub-items using a 7-point Likert scale (1 = strongly disagree; 7 = strongly agree). CQ contains 5 sub-items; TS contains 3 sub-items; PU contains 3 sub-items; PEOU contains 4 sub-items; SA contains 3 sub-items; SE contains 5 sub-items, and BI contains 3 sub-items. The complete questionnaire consisted of two parts: a survey regarding the subjects’ demographic characteristics, including gender, major, grade, and scale. The data were analyzed to test their reliability and validity. Confirmative factor analysis (CFA) was performed to examine the construct validity and composite reliability of the model.
