Educational outcomes, such as knowledge, confidence in performance, ability in nursing practice, and satisfaction with learning methods in caring for children with croup, were compared between groups of students that received education through simulation combined with pre‐education, simulation only, and pre‐education only. In this quasi‐experimental design, the educational intervention for the experimental group was the pre‐education modality. Data from a convenience sample of 127 senior nursing students were drawn from three nursing schools in South Korea. There were significant differences in the mean scores of knowledge, confidence in performance, satisfaction with the learning method, and ability in nursing practice between the three groups. Pre‐education with simulation significantly enhanced students' knowledge, confidence in performance, ability in nursing practice, and satisfaction with learning methods compared with pre‐education or simulation alone. Simulation strategies should focus more on enhancing nursing students' learning outcomes.
