In the literature, it is emphasized that the use of simulation improves the communication skills of the participants and that teamwork is important in providing patient safety and effective care. It is stated that students experience fear and anxiety in practice due to their lack of knowledge and clinical experience. Continuous repetitions and regular feedback provided by the trainings made by applying simulation increase the performance and self-confidence of the student. It is stated that the possibility of repeated application reduces the anxiety of the students. It is seen that different simulation types are used in the development of skills in nursing students in studies on this subject. As a result; It is seen that simulation has unlimited potential as an educational method and tool in nursing education. However; No study was found on a specific nursing practice and within the simulation scenario. of the study; In this study, it is aimed to evaluate the effectiveness of using standardized/simulated patient and low-fidelity patient models in head bath practice, which is one of the basic skills of nursing students. As a result of this study, the effective training method in the teaching of the head bath skill, which is taught within the scope of the nursing principles course, will be determined. In addition, it is thought that the periodical follow-up of the students (right after the teaching and at the end of the semester) and the permanence level of this education include a different aspect from other studies.

There are different definitions in the literature about simulation. Gaba (2004) defines the simulation technique as "reminding or imitating important aspects of the real environment in an interactive way, accompanied by guides, in order to change or improve real experiences". Although there is no single definition of simulation, in general, simulation is a learning method in which a realistic model of an event or process is developed or imitated. Simulation in nursing education is a learning method applied in different ways to minimize the risks that students may encounter in the clinical setting.

There are many different types of simulations that provide knowledge and skills to nursing students, guide about the problems that may be encountered in the clinical environment, and are suitable for real situations. These are divided into low-tech simulation models, standard/simulated patient, computer-assisted simulations, virtual reality and touch systems, and integrated simulations.

The use of simulation in the nursing education curriculum has many advantages. The use of simulation in nursing education; By providing experience-based learning opportunities, it enables students to increase their self-confidence and improve their clinical decision-making skills. Students gain the ability to perform complete care, decision making, assessment, teamwork, skill development and management in a safe environment without misunderstanding the patient's current situation or fear of failure.

The use of simulation in nursing education is gaining importance in Turkey due to the increase in the number of students, insufficient clinical areas and ensuring patient safety.

Inclusion Criteria:

For randomization, a randomization table was created using the http://stattrek.com/statistics/random-numbergenerator.aspx site. As a result, the sample of the research; The purpose of the study was explained, and after the briefing, a total of 80 students, 40 students in both groups, who were allowed to participate in the research and who met the criteria for inclusion in the sample, formed.
