Purpose: This mixed-methods study developed an infant nursing simulation practice program for nursing students and analyzed its effects on nursing knowledge, critical thinking disposition, clinical competence, and learning satisfaction through quantitative research. The study also qualitatively explored student’s experiences through focus group interviews. Methods: A mixed-methods design was employed incorporating a nonequivalent one-group pretest-posttest design(N=62) and focus group interviews(n=11). Participants were nursing students who applied for simulation training at a university between March and June, 2024. Quantitative data were analyzed using descriptive statistics and paired t-test, while qualitative data were analyzed through thematic analysis. Results: Quantitative findings revealed that participation in the infant care simulation program, result in significant inprovements in nursing knowledge (t=-3.60, p<.001) and clinical competence(t=-2.95, p=.004). However no significant improvement critical thinking disposition was observed. Qualitative analysis revealed three themes: ‘performing nursing care for infants’, ‘experiencing real situations and repeated practice’, and ‘reflection on nursing performance and disappointment with the set contents’. Conclusion: The infant nursing simulation training effectively enhanced nursing knowledge and clinical competence, providing a positive learning experience for nursing students. Further development and evaluation of simulation training across various subjects are recommended to confirm its broader educational effectiveness.
