4. Analysis and Findings
4.1. Reliability and Construct Validity Analysis The reliability and validity of the scale were evaluated using reliability and convergent validity criteria. Reliability was established by calculating Cronbach’s alpha to measure the internal consistency of the measurement. A pilot study was carried out in which 30 students who completed undergraduate courses conducted with the BL mode for at least one year were invited to complete the online questionnaire posted on a questionnaire- sharing website called “The Scale Star.” As Hair et al. pointed out, Cronbach’s alpha coefficient must be at least 0.7 [ 45 ]. As shown in Table 1 , Cronbach’s alpha values for all constructs were above 0.7. The Cronbach’s alpha for CQ, PEOU, and BI are above 0.9, indicating a high degree of internal consistency of these constructs. Sustainability 2022, 14, 16428 6 of 14 Table 1.

A total of 461 valid questionnaire results were collected after excluding invalid answers or those that were not completed within the time limit. The first part of the survey consisted of the demographic characteristics of the respondents. The results indicated the representativeness of the subjects. As is shown in Table 2 , in terms of gender, there was nearly an equal number of male and female learners. As for the major allocation, there were more science majors than arts majors, which was within the acceptable level. The majority of the respondents were juniors, which was due to the fact that many freshmen and sophomores did not meet the sampling inclusion criteria. Students in their senior year were required to perform an internship; therefore, they were not as motivated as juniors to Download 0.86 Mb. Do'stlaringiz bilan baham: |
