Environmental ethics is a sub-branch of ethics that determines moral values and principles towards the environment. It is the common responsibility of all humanity to improve and protect the environment/nature and to hand it over to the next generations. For this reason, every segment of society should have environmental ethics awareness. Empathy is an important concept in raising awareness of environmental ethics. It is stated that the awareness of environmental ethics is also developed in people who have developed empathy skills. For this reason, it is recommended to create training programs that enable people to develop their empathy skills. The formation and establishment of environmental ethics awareness in people can prevent the occurrence of environmental problems. This can be achieved by providing an effective environmental education. Technological developments such as virtual reality can be used in environmental education. Virtual reality technologies are called empathy machines as they create a sense of presence in users. For this reason, the perception of presence in virtual reality and being included in the narrative are effective in developing empathy in the person. It is stated that the perspectives acquired in virtual reality develop empathy and encourage behaviors in favor of society in a few weeks. Virtual reality technologies are useful for us researchers, both in terms of developing empathy towards environmental problems and creating awareness of environmental ethics as an educational tool. For this reason, in this study, the effect of virtual reality supported environmental education on nurses' empathy and environmental ethics awareness levels was tried to be examined with a quasi-experimental research.

RESEARCH DESIGN This research is a three-arm randomized controlled experimental study conducted prospectively to compare the effect of virtual reality-supported environmental education on nurses' environmental ethics approaches and empathy levels.

LOCATION AND CHARACTERISTICS OF THE STUDY This research was conducted at a State Hospital located in a province in the Eastern Anatolia Region between 01.10.2022 and 31.04.2023. The hospital consists of primary adult intensive care, secondary adult intensive care, secondary neonatal intensive care, six-bedded wards, operating theatre service, emergency department, palliative care unit, dialysis unit, and outpatient care service. The working hours of the hospital are organized in two shifts, 08.00-16.00 and 16.00-08.00, or 24 hours (full day).

POPULATION AND SAMPLE SELECTION The research was conducted with 91 nurses who volunteered to participate from among 101 nurses working at a State Hospital in a province in the Eastern Anatolia Region between 01.10.2022 and 31.04.2023. The total sample size was calculated as 90 (n=90) using G-POWER program with .4 (Cohen) effect size, 92% power, and .05 error margin based on percentage measurement values of the methods to be studied obtained from literature review (Faul et al., 2007). Considering possible losses, 33 nurses were planned to be included in each group, and randomization was performed over 91 nurses. None of the nurses included in the study met the exclusion criteria, and the study was concluded with 91 nurses.

Dependent and Independent Variables of the Study The main independent variable of the study is virtual reality-supported environmental education. Other sub-variables are data obtained through the "Nurse Introduction Form" and the "Empathy Level Determination Scale." The dependent variable of the study is data obtained through the "Environmental Ethics Approaches Scale."
