Background: Transferring what has been learned in the classroom to clinical application is the main goal of nursing education. Our previous intervention study, in which a web-based interactive situational teaching strategy in a nursing ethic course was conducted as an experimental group, and the students in the class who were taught using a traditional teaching strategy was treated as the comparative group. The results, which were evaluated immediately after the class, showed that the web-based interactive situational teaching enhanced the students' competency in ethical reasoning and problem solving compared to traditional teaching. Purpose: This study followed the previous study and aimed to compare the effects of the learning transfer between the two groups in clinical performance as reflected in their internship scores, clinical practice, and self-efficacy assessment. It also explored the factors influencing this transfer. Method: A predictive correlation-based research design was adopted to compare the students' internship scores, clinical judgment abilities, and self-efficacy in clinical internships between two groups. The students' self-efficacy was measured using a self-administered structured questionnaire, while their internship scores and clinical judgment abilities were evaluated by their clinical instructors. The data obtained were statistically analyzed using SPSS 23 software. Results: The nursing students who participated in the web-based interactive situational teaching course did not significantly outperform those who received traditional teaching in their clinical judgment and internship scores. The main variable that significantly affected the clinical self-efficacy of nursing students was the degree of support from the internship instructors. Conclusion: Nursing students' clinical performance is affected by multiple factors and is not solely determined by the curriculum or teaching strategies. The degree of instructor support during the internship process significantly affected the students' self-efficacy in clinical performance.
