Pressure ulcer is defined by the European Pressure Ulcer Advisory Panel (EPUAP) and the National Pressure Ulcer Advisory Panel (NPUAP) as "localized skin and/or skin, usually arising over bony prominences, caused by pressure alone, or by a combination of shear and pressure. subcutaneous tissue damage. Pressure ulcer is a painful, costly and preventable health problem that is frequently encountered especially in geriatrics group and in patients with limited daily activities or bedridden. It is an undesirable health care problem that is difficult to treat, but it is possible to prevent the development of pressure ulcers with the measures to be taken from the beginning of the disease. In order for nurses to fulfill their role in preventing pressure ulcers, the content of undergraduate education programs needs to be arranged in a way that will provide them with knowledge and skills in the prevention of pressure ulcers, diagnosis of risky patients and maintenance of care. In Northern Cyprus, knowledge and skills related to pressure sores are provided to students in the basic nursing education curriculum. However, the subject of pressure ulcer in the education programs of nursing schools differs in terms of content and duration, and most of the hospitals do not have a standard guide and training program for the prevention of pressure ulcers. In Northern Cyprus, studies on the knowledge and practices of nursing students to prevent pressure ulcers are limited. According to the results of a study conducted in Turkey, it has been reported that a significant portion of nursing students have a positive attitude towards preventing pressure ulcers, but their general knowledge about preventing pressure ulcers is insufficient. In another study, it was reported that 70.7% of nursing students encountered patients with pressure ulcers during hospital practices, but research findings and the knowledge of nursing students to prevent the development of pressure ulcers were insufficient. Similarly, in studies conducted with nursing students using different scales, it has been reported that students' knowledge levels about preventing pressure ulcers are low. This research was planned in accordance with the randomized controlled research method in order to determine the knowledge levels and practices of firts year nursing students to prevent pressure ulcers.

The population of the research will be 2nd year students studying at the Faculty of Health Sciences Nursing Department in the 2021-2022 Academic Year Spring Semester. Since 1st year students do not have any information about pressure ulcers yet and other classes (3rd, 4th grade students) have received information about pressure ulcers before, they were excluded from the study, as this would affect the average scores. The entire population that meets the criteria for inclusion in the study will be included in the sample. Before starting the research, the enclosed Informed Consent Form will be distributed to the students and their consent will be obtained stating that they are willing to participate in the research. "Student Descriptive Characteristics Questionnaire and "Pressure ulcer Knowledge Assessment Tool" updated version (PUKAT 2.0) all groups will be collected before and after the training by face-to-face interview method. Students will be divided into two groups by simple randomization method. Group distributions will be divided into group 1 and group 2 by drawing lots. Students who are divided into groups will not know what the group they belong to means In this case, group 1 students will be included in the research in accordance with the flipped learning model, and group 2 students will be included in the research in accordance with the traditional education method. Group 1 students and educational materials (lecture presentation, video) will be uploaded through the system in accordance with the flipped learning model, and students will be asked to come prepared to the planned lesson. No classical presentations will be made to the students, but the education will be carried out in the form of question and answer discussion, in line with the Flipped Learning model. The training, consisting of Group 2 students and a Powerpoint presentation, will last 20-30 on average, and will be given in accordance with the traditional education model. After the lesson, the questions of the students who have questions will be answered. After obtaining the necessary ethics committee approval, the data collection phase will begin.
