The haptic-assisted virtual reality simulation developed for the intervention group will enable them to practice nursing skills.

Classic nursing skills education with task trainer in the nursing skills laboratory.

The virtual reality application will be developed using the Unity game engine. The VR simulation environment, which will progress through scenarios, will include taking vital signs, performing aspiration, performing a nasogastric catheterization, oxygen therapy, performing physical examinations, and performing subcutaneous injections.

This scale assesses nursing students' anxiety and self-confidence levels in clinical decision-making. Separate scores are obtained for self-confidence and anxiety from the scale, which consists of a total of 27 questions. Both the self-confidence and anxiety sections of the scale have three subscales: "Using resources to obtain information and listening carefully (13 questions)", "Using available information to identify the problem (7 questions)", and "Knowing and taking action (7 questions)". Higher scores on self-confidence and its subdimensions indicate increased levels of self-confidence in clinical decision-making among students. Low scores on the anxiety section and its subdimensions indicate low levels of anxiety in clinical decision-making. It is a six-point Likert-type scale. The lowest possible score on the self-confidence and anxiety sections is 27, and the highest possible score is 162.

The Knowledge Test, prepared in line with the literature, consists of 20 questions. Each question will be scored with "1" point for a correct answer and "0" points for an incorrect answer. Questions covering all skill applications will be scored out of 100, with the total number of correct answers completing the score. The form was evaluated by ten experts in the field of Nursing Fundamentals outside of the study and finalized. The purpose of the expert opinion is to examine the items according to criteria such as whether the test measures behavior according to its structure, its comprehensibility in terms of language, whether there are scientific errors, grammatical errors, and the suitability of the items for the group to be applied to, and to make the necessary corrections.

The performance report, which awards points out of 100, will include scoring for nursing interventions. Performance report scores range from 0 to 100; minimum score "0", maximum score "100". The performance report applied with the task trainer has been created to be identical to the virtual patient simulation performance report, and OSCE steps have been defined. The performance forms created will be evaluated by the researcher during the student's application. All students (intervention and control groups) will use the application at least once within the scope of the study. For the success assessment in the applications, the cutoff score is considered as follows: 50.00-59.99 is passing, 60.00-69.99 is average, 70.00-84.99 is good, and 85.00-100 is excellent. A higher score indicates higher performance.
