This study was motivated by low student learning outcomes in the Business Communication subject at SMKN 1 Cilimus and a learning process that was still dominated by conventional methods. The condition was reflected in limited student participation and difficulties in developing an in-depth understanding of learning materials. This study aimed to determine the effect of the Feynman learning method assisted by Educaplay on students’ learning outcomes in Business Communication, particularly business ethics material, at SMKN 1 Cilimus. The study employed a quantitative approach with an experimental design using a Pretest-Posttest Control Group Design. The participants were 50 students consisting of 25 Grade XI students as the experimental group and 25 Grade XII students as the control group. Data were collected through learning outcome tests, observation, questionnaires, and documentation. Data analysis included descriptive statistics, Shapiro-Wilk normality testing, homogeneity testing, N-Gain analysis, and an Independent Samples t-Test. The mean N-Gain of the experimental group was 0.6452, categorized as moderate, while the control group obtained 0.0860, categorized as low. The Independent Samples t-Test produced t = 8.445, df = 48, significance = 0.000, and Mean Difference = 0.55756. Thus, the improvement in learning outcomes differed significantly between the two groups. The findings indicate that the Feynman learning method assisted by Educaplay was associated with higher learning outcome improvement in the Business Communication learning context at SMKN 1 Cilimus.
