This study is planned as a randomized controlled trial to examine the effects of the use of QR (Quick Response) Code-supported materials prepared for perioperative care by nursing students during clinical practice on the knowledge levels of nursing students and their attitudes towards evidence-based nursing.

Evidence-based nursing is an approach that started with the works of Florence Nightingale and aims to base nursing practices on scientific foundations over time. Nurses must have a variety of roles, including the roles of caregiver, educator, leader, and patient advocate, as well as a commitment to evidence-based practice. Therefore, instead of traditional learning methods, students should learn evidence-based practices and take on roles during their clinical practice to provide safe and high-quality care in order to have a professional identity professionally. The World Health Organization (2016) report on "Nurse Educator Core Competencies" recommends that nurse educators facilitate active learning in the education process, select and use appropriate technologies and materials, and encourage individualized experiential learning. For this reason, in addition to constantly innovative health practices, new developments in the field of educational technologies should be followed closely. QR (Quick Response) Code technology is a tool used to share web-based information. The use of QR Codes in education is an innovative approach. It makes the education process of nursing students interactive with today's technology and increases student participation and access to education.

Upon reviewing the literature, no studies were found that evaluated the effect of QR Code-supported education, which is an innovative education method in nursing students during clinical practice, on the students' knowledge level and evidence-based attitude. Therefore, this study is planned to be conducted on nursing students. The results of this study are expected to contribute to that students will participate interactively in the evidence-based learning and practicing process during clinical education, and the educational methods used will gain a critical and innovative approach for both students and educators.

The study will conduct as a prospective randomized controlled trial. After obtaining verbal and written consent from the students before and after the clinical practice, the study will conduct with various data collection forms.

These forms are; Student Identification Form, Knowledge Level Measurement Test for Evidence-Based Practices Including Perioperative Care, Evidence-Based Nursing Attitude Questionnaire, Form for Opinions on the Use of QR Codes will be used.

The QR (Quick-Response) group in group- I (n=30), and group II (n=30) will be the control group. The study has 2 stages. In the first stage, the descriptive characteristics of the participants and their knowledge level regarding evidence-based practices including perioperative care will be measured for both groups.

During the second stage of their clinical practice, participants in the intervention group will receive support through QR code-enabled perioperative educational materials. These QR code-supported resources will be available to the participants throughout their entire clinical education process. Participants in the control group will continue their clinical practice using the learning methods available in the educational curriculum. Following clinical practice with participants in both intervention and control groups, researchers will assess participants' knowledge levels using a measurement test focusing on evidence-based practices including perioperative care. Additionally, participant's attitudes toward evidence-based nursing will be assessed using an attitude scale on this topic. In addition, researchers will collect participants' opinions on using QR Codes in the intervention group through a designated feedback form.
