Purpose: The purpose of this study was to explore the first learning experiences of undergraduate nursing students in team based high-fidelity simulation. Methods: The participants in this study were 13 undergraduate students at a university in Korea. The students were place in a setting of high-fidelity simulation to manage neurological patients. Data were collected from August, 2013 to September, 2013, through in-depth interviews and were analyzed on the basis of Colaizzi’s phenomenological methodology. Results: Five essential themes were extracts that were as follows 1) Thoughts about patients through the training manikin 2) Feeling of being engaged in practical training 3) Recognition of the importance of the team and teammates 4) Evaluation and analysis of the education content 5) Prospects of improving the capacity for nursing practice. Conclusion: Although the students experienced simulation practicum for the first time, it was noticeable that they tried to actively utilize their theoretical knowledge on the training high-fidelity manikin during simulation practicum. Also, it was observed that they recognized the importance of cooperating with their teammates through team role-playing, assuming a professional attitude as a result. Furthermore, analysis on the content of the education and self-evaluation would help foster the capacity to provide total care for patients.
