Using expert-modeling videos in telesimulations to teach pediatric and neonatal nursing.

to assess the perception of self-efficacy, self-confidence, and satisfaction of undergraduate nursing students during the use of expert-modeling videos as a learning strategy in the period of social distancing. this was a descriptive study with undergraduates studying disciplines of caring for hospitalized newborns and children at a higher education nursing institution in the interior of the state of São Paulo, Brazil. Activities were organized in three moments, in real time: prebriefing, expert-modeling videos and debriefing. The expert-modeling videos replaced the clinical simulation scenario during the social distancing required by the COVID-19 pandemic, for the development of telesimulation. Specific validated scales were used to analyze students' self-confidence, self-efficacy and satisfaction. Content analysis assessed the advantages and disadvantages of using expert-modeling videos. thirty-nine undergraduates took part in the study. High levels of self-confidence, self-efficacy and satisfaction were found among the participants. The advantages of expert-modeling videos were organized into the following categories: Convenience, Security and continuity of studies and Efficient teaching method, and the disadvantages into Problems with technology, Distractions, Lack of personal contact and Mental fatigue. telesimulation activities were consolidated as strategies that enabled learning in times of emergency online teaching due to the realness of telesimulation, the development of skills in caring for children and newborns and the link between theory and practice.
