Depending on the education system, the increasing number of students, inadequate practice/skill laboratories, a small number of lecturers and students with limited time in the clinic have a negative impact on obtaining appropriate clinical experience. The virtual learning environment experience will prepare the student for the clinic in the most realistic way and will reduce the risk of errors in clinical care and treatment. In light of this information, presenting the learning environment of the future to the student will prepare the student both in the clinical practice area and in the professional environment as self-confident and highly equipped The study was planned with a mixed method consisting of single-blind randomized controlled experiment and focus group interview methods. The research was planned to be carried out during the pediatric nursing course period between 2023-2024 Fall Semester October-December. Participants will be students taking a pediatric nursing course. Scales and Forms to be used in the Study; Informed Consent and Demographic Data Collection Form, Expert Opinion Form, Proficiency Scale for Nursing Students, Augmented Reality Applications Attitude Scale, Pre and Post Test, Student Case Form, • Focus Group Interview Form and Distance Education Satisfaction Scale of university life.

The universe of the research consists of all students who take and continue the 2023 - 2024 fall term child health and diseases nursing course (N: 190). It will try to reach the universe where the sample selection of the research will not be made.

To measure the learning efficiency of pediatric nursing students in infant orogastric tube care application in two different skill laboratories, considering the feeding pattern from Gordon's Functional Health patterns. (University skills lab and metaverse-based clinical skills lab) As a result, the learning levels of the students in the metaverse-based clinical skills laboratory environment will be higher than in the skills laboratory. It will also increase the student's self-confidence in the field of pediatric nursing practice.

Depending on the education system, the increasing number of students, inadequate practice/skill laboratories, a small number of lecturers, and students with limited time in the clinic have a negative impact on obtaining appropriate clinical experience. In addition, from the perspective of Bloom's taxonomy, learning; reminding, understanding, applying, analysing, evaluating and creating. Due to the limitations in clinical applications, students often cannot progress to advanced stages from the application part of Bloom's taxonomy.

Today, clinical application areas are limited within the structure of the health care system. In addition, considering the developments in technology, it is necessary to include innovative approaches in education in line with the expectations of students coming to higher education. Therefore, simulation-based learning has been one of the effective methods in preparing nursing students for the clinic and profession with knowledge and skills.

Use of virtual reality simulation among nursing students and working nurses: Among the three learning outcomes (skill-based, cognitive, and affective) in a systematic review, virtual worlds are most effective in improving cognitive outcomes such as theoretical knowledge. This situation suggests that virtual worlds can be used as an alternative or complementary method in teaching theoretical knowledge in nursing education and that a learning environment should be designed in accordance with the innovations brought by technology for clinical applications in nursing education. In addition, the prevalence and demand of online/distance education systems in the education system and the necessity of using them in extraordinary situations increase the necessity of a technological learning environment. Virtual reality, augmented reality, artificial intelligence and metaverse-based simulation environment are among the most suitable methods that can be chosen to develop learning, decision making, critical thinking and clinical skills.

Metaverse is Augmented Reality or Cross Reality (XR) based on technologies that enable multi-sensory interactions with virtual environments, digital objects, and people. XR includes Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR) (Milgram et all., 1994). The representative accuracy of the XR system is ensured by stereoscopic displays capable of transmitting depth perception. XR systems allow active interaction with virtual items through the use of motion controllers. These are handheld input devices with a handle, buttons, triggers, and thumbsticks. Using controllers, users can touch, hold, manipulate and operate virtual objects. This ability enables them to be active in any educational experience (such as nursing care).

The importance of this study is to provide an evidence-based virtual education environment to the literature and to ensure that it is ready for extraordinary situations in the field of education (such as distance education during the pandemic period). This should be done by designing and developing a virtual learning environment. While aiming to make this environment in the study, was based on evidence. The use of Gordon's Functional Health Patterns in the design of the virtual learning environment is important in terms of meeting the patient and starting the nursing process when the student first enters the clinical environment The virtual learning environment experience will prepare the student for the clinic in the most realistic way and will reduce the risk of errors in clinical care and treatment. In the light of this information, presenting the learning environment of the future to the students will prepare the student both in the clinical practice area and in the professional environment as self-confident and highly equipped.

The aim of the study is to analyze two different skill laboratory experiences of pediatric nursing students (the course and practice laboratory experiences they took during the formal education period and the lessons and practice experiences they received in the metaverse -based skill laboratory environment) within the feeding pattern of Gordon's Functional Health Patterns, through the example of orogastric tube application in the premature baby is to compare. The study was planned with a mixed method consisting of single-blind randomized controlled experiment and focus group interview methods.

AIM To measure the learning efficiency of pediatric nursing students in infant orogastric tube care practice in two different skill laboratories, taking into account the feeding pattern from Gordon's Functional Health patterns. (University skills laboratory and metaverse-based clinical skills laboratory) The study was planned with a mixed method consisting of single-blind randomized controlled experiment and focus group interview methods.

Research time 2023-2024 Fall Semester is the period of pediatric nursing course between October and December. Participants are students taking pediatric nursing course.

Ethical Considerations and Limitations of Research The study will be initiated by obtaining informed consent from the students who took the pediatric nursing course during the academic year. Institutional and ethical committee permissions will be obtained. (No: E-31034136-302.08.01-649) The research was carried out within the framework of the Declaration of Helsinki, good clinical guide practices and the law on the protection of personal information will be followed.

The limitations encountered in this study are listed below.

• The sample of the research is limited to the students who take a pediatric nursing course in the Department of Nursing at the Faculty of Health Sciences of Medipol University.
• Expert opinions on the metaverse-based clinical skills laboratory will be obtained from academic staff who are experts in the field of pediatric nursing and engineering.
• Experience of participants in the designed metaverse-based clinical skills laboratory; It is limited to the features of the virtual reality glasses and equipment (headset, controller, etc.) used within the scope of the study.

Sample of the Study The universe of the study consists of students (N: 190) who took a pediatric nursing course in the 3rd year of the Teaching Department at Istanbul Medipol University. The sample of the study will consist of the students who took the 3rd year child health and diseases nursing course in the nursing department, accepted the study, and met the study criteria. The net participant count to be included in the sample will be determined within the current selection criteria and after the G Powers analysis. The sample size of the study was determined by the post. doc. The sample size will be clarified. With the simple randomization method, students will be assigned to the experimental and control groups. Even the last digit of the student number will be randomized to the experimental group and odd ones will be randomized to the control group Sample Selection Criteria In the sample, it will be considered that virtual reality users may be exposed to strong psychological effects. Discomforts that occur in virtual experiences, which are seen as motion sickness or simulation disease, are among these effects. Simulation hospital is similar to transportation sickness but going through VR experience. It is recommended that motion sickness arises from the accumulation of visual and vestibular senses as its organization. It is seen as headache, fatigue, heaviness, and disorientation in the weight given with the common perception. Advances in Head-Weared Device (HMD) technology may have increased motion sickness enclosures due to increased consumers and levels of realism in virtual reality.
