This randomized controlled trial aims to examine the effect of Gimkit-based game-enhanced learning on achievement motivation, academic performance, and game experience among first-year nursing students during respiratory system skills training. Students are randomly assigned to either the experimental group, which receives standard respiratory skills laboratory training followed by a Gimkit game session designed to reinforce key concepts, or the control group, which receives only the standard skills laboratory training. Achievement motivation is assessed using the Expectancy-Value Theory-based Achievement Motivation Scale before and after the intervention in both groups. Academic performance is evaluated using a 10-item multiple-choice digital test administered after the skills laboratory session. Additionally, the Game Experience Scale is administered to students in the experimental group to measure their perceptions of game-based learning. The study aims to determine whether game-based reinforcement improves motivation and learning outcomes compared with traditional laboratory instruction.
