Students in the intervention group will first receive traditional theoretical and practical training in the department's curriculum using standard methods; they will then participate in the developed serious game application.

Students in the control group will only receive theoretical and practical lessons included in the department curriculum using traditional teaching methods during the study period; no additional intervention will be applied. The scope of education will be limited to the existing course content, and no additional simulation/game-based activities will be conducted. In accordance with ethical principles, the same serious game application will be offered to the students in the control group after the research is completed, and these students will also be provided with the opportunity to benefit from the game.
