<![CDATA[This study aims to obtain empirical evidence regarding the effectiveness of QR Code-assisted board games in improving students’ learning outcomes on the Doppler Effect material. The research employed a quantitative approach with a pretest–posttest control group design. All data collected in this study were quantitative in nature. Learning outcome data were obtained through a 30-item multiple-choice test, while student engagement, affective, and psychomotor aspects were measured using structured observation sheets and student response questionnaires with numerical scoring scales. The results showed a greater improvement in the experimental class compared to the control class. The average pretest and posttest scores of the control class increased from 36.38 to 54.25 with an N-Gain of 0.24 (low category), whereas the experimental class increased from 37.68 to 78.89 with an N-Gain of 0.62 (moderate category). Observation results indicated that student activity in the experimental class reached 76%, higher than the control class at 36%. The experimental class also obtained higher scores in affective (87.50) and psychomotor (80.57) aspects compared to the control class. Student response questionnaire results showed a very positive perception of the media, with an average score of 89.3%. Based on these findings, the implementation of QR Code-assisted board games was associated with improved cognitive, affective, and psychomotor outcomes within the research sample. These conclusions are limited to the study context and participants involved.]]>
