## 3 Methodology
### Study Design  
For the current research, a case study design involving a quantitative approach was implemented, using a survey adapted from [PERSON] et al. [15] based on UTAUT. However, some changes were made to the original survey items to suit the research context. For example, in Item 1 of the questionnaire on the topic of performance expectancy, the word 'job' was changed to 'course', as follows: \(\mathsf{T}\) would find the system useful on my course'. Meanwhile, a four-point Likert scale was adopted to ensure clearly defined answers from the participants. The survey (Appendix A) was distributed electronically via Google Forms to facilitate data collection. The questionnaire was also translated into Arabic to ensure the learners' understanding, and a translation expert was designated to check the translation. The validity of the content was determined to check the suitability of the tool to answer the research questions, whereupon two experts in the field were asked to give their opinions. Reliability refers to the degree of consistency or stability in the results of a study if it is conducted with the same respondents on repeated occasions. Reliability is therefore a very important aspect of selecting a questionnaire instrument. In order to evaluate the reliability of the questionnaire administered in this current study, the [PERSON]'s alpha values were calculated for each dimension. [PERSON]'s alpha (\(\alpha\)), developed by educational psychologist [PERSON] in 1951, is the most common estimate of reliability. Based on the intercorrelations of the observed indicator variables, [PERSON]'s alpha produces values of between 0 and 1, with an acceptable range of 0.7-1. Figure 1: Services provided by the platform. The above table demonstrates that the research data passed the reliability test, because the [PERSON]'s alpha value for the questionnaire was 0.864 (greater than 0.7), and all the [PERSON]'s alpha values exceeded the acceptable minimum. Regarding the research participants, comprehensive sampling was carried out, as the survey was distributed to all male and female Level 4 learners in the English Diploma Programme. This sample was selected because the learners had already used the platform for three terms. Therefore, they would have had sufficient experience of it to be able to give their opinions. Moreover, they had one more term remaining before they graduated. The English Diploma Programme is described on the Saudi Electronic University website as an English Language Diploma on the Internet, accessible to male and female students all over the Kingdom as of Fall 2021. The aim of this Programme is \"to prepare learners interested in English studies to become highly competent in English language practice\" [21]. Its overarching purpose is to equip learners \"with the various skills and knowledge required in the job market to have a successful career...\" (ibid.). Twenty different English language courses are available within the Diploma Programme, consisting of \"translation, interpreting, and research and presentation skills\" (ibid.). The course designers are highlighted as \"experienced faculty members whose research and scientific interests lie at the intersection of those academic fields\" (ibid.). Each learner is expected to meet a number of milestones over the course of the Programme. From an ethical perspective, every effort was made to hide the participants' identities in the study in consideration of the need for participant anonymity and confidentiality. Moreover, participation was purely voluntary and did not affect the participants' grades. Prior to their participation, the respondents were asked to sign informed consent forms. Finally, all participants were informed of their right to withdraw from the study at any time. The researcher contacted the head of the English department from the College of Science and Theoretical Studies at the Saudi Electronic University where the platform was being implemented. This was to verify that the study could be conducted. Approval was granted orally.
