The research is planned to be conducted as a quasi-experimental study using pre-test-post-test in order to examine the effect of simulation-based applied training for children and families on the communication and problem solving skills of pediatric nurses. The research will be conducted in the pediatric simulation laboratory of Gazi University Faculty of Nursing, Department of Pediatric Nursing. Pediatric Nursing Practice Laboratory consists of two application areas. In the first application area, there is a simulation room and a control room used by the instructors, where student practices are observed and evaluated through mirror glass. The second application area is used to evaluate the analysis phase and feedbacks of the participants' applications, which are videotaped after the simulation applications, by coming together with the participants after the application. The research sample will consist of 48 nurses who work with pediatric patients in a private hospital and agree to participate in the study. After obtaining the necessary permissions for the study, a 4-hour pre-application will be made with a different group of nurses not included in the study and all modules and forms will be applied. The necessary arrangements identified will be made before the application. Simulation application groups will be formed with groups of 3 people on a predetermined day and time according to the working days and hours of the nurses who agree to participate in the study. Before the simulation application, the pediatric simulation laboratory will be introduced to the nurses who agree to participate in the study. The orientation of the nurses to the simulation environment, the materials to be used and the characteristics of the model (expected goal, what they are asked to do, application time, evaluation) will be provided. The pre-created semi-structured scenario for the themes determined before the simulation application will be explained to the nurses. The simulation practice will last approximately 1.5 hours (40 min simulation practice + 50 min debriefing = 1.5 hours). During the implementation, the scenario will be realized with video shooting. While the researchers will manage the scenario, they will take notes on the practices of the nurses. After the simulation application, feedback will be provided to the nurses about the positive aspects and skills that need to be developed by the researchers through a debriefing interview over the video recordings. The data obtained will be evaluated using SPSS 25.0 package program. Data will be evaluated by descriptive analysis (percentage, frequency). The confidence interval will be accepted as 0.95. In the study, firstly, it will be evaluated whether the data obtained show normal distribution or not. Pre-test and post-test scale scores will be analyzed and evaluated with t-test for dependent groups. The cause and effect relationship between the scales will be analyzed by regression analysis. In the analysis of the results, the findings will be considered statistically significant if p\<0.05.
