Brief Summary

Short Title: Impact of VR-Based Learning Tools on Nursing Students' Thoracic and Lung Examination Skills

Short Summary: This study evaluates the impact of a virtual reality (VR) based learning tool on nursing students' knowledge and skills in thoracic and lung physical examinations. Designed as a single-blind, pre-test-post-test, control group, parallel-group randomized controlled trial in accordance with SPIRIT 2013 guidelines, the study was conducted with 82 second-year nursing students from Gazi University, comprising 41 students in the experimental group and 41 in the control group. Initially, participants were informed about the study and received theoretical training during the first week. The second week included a review through demonstration videos, while the third week involved hands-on practice using high-fidelity simulators in a skills lab for auscultation and physical examination. The final exam was administered in the fifth week. Participants meeting eligibility criteria were stratified by gender and academic performance, then randomly assigned to groups by an independent statistician. Pre-reading materials were distributed one week before the intervention, followed by an evaluation of knowledge and skill levels. The experimental group underwent VR-based training, whereas the control group received traditional instruction. Final assessments of knowledge and skills were conducted one week post-training. Data collection included demographic forms, knowledge tests, skill assessments, and student feedback. Blinding was applied to evaluators, participants, and statisticians to minimize bias. Data analysis will employ statistical software, utilizing parametric tests for normally distributed data and non-parametric tests for non-normally distributed data.

Research Question: What are the opinions of students in the experimental group regarding the use of the VR-based thorax and lung physical examination learning tool? Variables of the Study

Independent Variables:

Training Method: Small group instruction for the control group; VR-based thorax and lung physical examination learning tool for the experimental group.

Dependent Variables:

Knowledge Level: Knowledge as measured by pre-test and post-test results. Skill Level: Skill level assessed by pre-skill and post-skill measurements.

Control Variables:

Participants' gender. Participants' course achievement scores. Materials and Method Type of Research: This study was designed as a single-blind, pretest-posttest, control group, parallel-group randomized controlled trial. The study was conducted in accordance with the SPIRIT 2013 guidelines. To minimize bias, the study protocol will be registered in the Clinical Trials registration system.

Location Characteristics and Time of the Research The study was conducted with students enrolled in the elective course "Health Assessment" (HEM 205) at Gazi University Faculty of Nursing during the 2023-2024 academic year. This two-credit elective course covers physical examination methods and techniques both theoretically and practically. Theoretical instruction occurs in classrooms, while practical training is provided in skills and simulation laboratories by field experts.

Population and Sample of the Study: The study population comprised second-year nursing students who had successfully completed their first year and were enrolled in the second year during the 2023-2024 academic year, and who selected the "Health Assessment" elective course (HEM 205) for the first time. The sample size for the study was calculated using GPower version 3.1.9.7 software. The sample size calculation in GPower utilized a t-test to assess the mean difference between two independent groups, with a priori values of α = 0.05, power = 0.90, and a large effect size (f = 0.80 Cohen's d). Based on the statistical analysis, a total sample of 68 participants was determined, with 34 assigned to the control group and 34 to the experimental group. In experimental research, it is critical to keep participant loss below 20% to minimize bias, and increasing the sample size helps control for potential bias due to attrition. To address potential losses, the study aimed to include 41 participants in each group, resulting in a total sample size of 82 participants.

Randomization: The randomization process was conducted in accordance with the CONSORT 2017 guidelines. An independent statistician stratified participants based on their achievement scores in the "Health Assessment" course and their gender. Female students with achievement scores between 2.00-3.00 (CC, CB, BB) were placed in the first stratum, while those with scores between 3.01-4.00 (BA, AA) were placed in the second stratum. Male students with achievement scores between 2.00-3.00 (CC, CB, BB) were assigned to the third stratum, and those with scores between 3.01-4.00 (BA, AA) were assigned to the fourth stratum. The statistician then performed simple randomization within each stratum using Excel software, resulting in random assignment of 41 students to the experimental group and 41 students to the control group.

Data Collection Tools Descriptive Characteristics Form: Developed by the researcher based on the literature, this form consists of fourteen questions. It includes eight questions regarding the demographic characteristics of the participants, one question concerning their eye health, one question about their willingness to choose the nursing profession, and four questions related to their technological attitudes.

Thorax and Lung Physical Examination Knowledge Test: Created by the researcher in alignment with the subject scope and learning objectives of the theoretical course on thorax and lung physical examination. This test comprises 20 questions with five options each, assessing knowledge necessary for performing thorax and lung physical examinations. Each question is scored out of 5 points, with higher scores indicating greater knowledge levels.

Thorax and Lung Physical Examination Skill Control Form: Designed to assess the initial and final skill levels of the students. This form, developed in accordance with the literature, includes a total of 48 procedural steps. Scores range from 0 to 96, with higher scores reflecting higher skill levels.

Student Opinion Form: Prepared by the researcher following relevant literature to gauge student opinions on the VR-based learning tool. This form has two sections. The first section, based on the technology acceptance model and literature review, consists of 29 items evaluating the ease of use (14 items) and perceived usefulness (15 items) of the VR tool. The second section contains six open-ended questions about the VR-based thorax and lung physical examination learning tool.

Content Validity Analysis Content validity was assessed by consulting 13 experts in physical examination methods and innovative digital education. They rated the forms on a 4-point Likert scale (4: Very appropriate, 3: Appropriate with minor adjustments, 2: Appropriate with major adjustments, 1: Not appropriate) regarding purpose, objectives, language, and expression. Expert opinions were analyzed using Davis's technique to calculate the content validity index, and agreement was tested with Kendall's W.

Designing a VR-Based Learning Tool

In designing the VR-based thorax and lung physical examination learning tool, the "Healthcare Implementation Standards of Best Practice Simulation Design" guide provided by the International Nursing Association for Clinical Simulation and Learning (INACSL) was used as the foundation. The design process was structured as follows:

Analysis Phase: The researcher completed training necessary for effective simulation design. Existing training methods of the target group were evaluated through SWOT analysis. The objectives of the learning tool were defined using SMART analysis.

Design Phase: The relevant literature was reviewed to determine the simulation method and scenario to be employed. The interaction methods within the VR learning tool and the scenario outline were developed.

Development Phase: High-quality graphics, models, and interaction methods were utilized to enhance the realism of the learning tool. Facilitative approaches were planned to support the participants' learning process.

Implementation Phase: Materials to guide the learning tool were prepared. The PEARLS method was employed to evaluate the learning tool following the simulation implementation. The tool's applicability and usability were assessed by participants, and necessary adjustments were made based on the feedback received from the pre-application.

Pre-Application: To evaluate the VR-based learning tool and data collection instruments, a pre-application was conducted with third-year students at Gazi University Faculty of Nursing who had previously completed the elective course "Health Assessment" (coded HEM 205). This pre-application assessed the clarity of the data collection tools in terms of language and expression, as well as the usability of the VR-based learning tool.

Application:

In the first week of the study, all participants underwent theoretical training. The second week included a review of the topic through demonstration videos, and skills training in the simulation laboratory was conducted in the third week. By the fifth week, all participants completed the final exam. Participants were then stratified and assigned to research groups based on their gender and course achievement scores.

The VR-based thorax and lung physical examination learning tool for the experimental group was designed and developed over a period of five months. During this time, all necessary preparations were completed. Pre-reading materials and demonstration videos were distributed to the participants. Seven days following the distribution of these materials, initial knowledge and skill assessments were conducted.

Practical training took place seven days after the initial assessments. The control group received 55 minutes of training in groups of 8, which included 7 minutes for an overview of the training purpose and content, 40 minutes for hands-on practice (5 minutes per student), and 8 minutes for feedback. The experimental group used the VR-based tool for 35 minutes, which comprised 7 minutes for an introduction to the Oculus Meta Quest 3, 20 minutes for skill practice on a virtual patient, and 8 minutes for a debriefing session.

Final knowledge and skill assessments were carried out seven days post-intervention. The experimental group participants completed the Student Opinion Form to provide feedback on the usability and applicability of the VR-based tool. Additionally, they received further training with the VR-based tool after the completion of all measurements and evaluations.

Analysis: Data will be analyzed using a computer program. The normal distribution of variables will be assessed through histograms, coefficient of variation, skewness, kurtosis, Kolmogorov-Smirnov, and Shapiro-Wilk tests (p<0.05). Descriptive statistics (number, percentage, mean, standard deviation) and Chi-square tests will be used. Parametric tests will be applied to normally distributed data, while non-parametric tests will be applied to non-normally distributed data. An independent sample t-test will be used for comparisons between two independent groups, ANOVA with Bonferroni correction for comparisons among more than two groups, and analysis of variance for repeated measures. For non-normally distributed data, Mann-Whitney U and Kruskal-Wallis H tests with Bonferroni correction will be applied. Randomization balance will be maintained using Intention-to-Treat (ITT) analysis.

Limitations of the Study: This study was conducted exclusively with second-year students enrolled at the Faculty of Nursing of a university in Turkey. This limitation affects the generalizability of the research findings, as the results may not be directly applicable to other student populations or educational settings.
