<![CDATA[This study aimed to analyze the differences in students’ Economics learning outcomes based on learning models, learning interest, and the interaction between the Problem Based Learning (PBL) model assisted by Wayground media and learning interest among tenth-grade students of SMA Negeri 5 Medan in the 2025/2026 academic year. This study employed a quasi-experimental method using a Pretest–Posttest Control Group Design with a 2 × 2 factorial design. The population consisted of 426 students, while the sample comprised 69 students selected through purposive sampling. Data were collected using a learning achievement test and a learning interest questionnaire, then analyzed using normality and homogeneity tests, followed by a Two-Way Analysis of Variance (Two-Way ANOVA). The findings revealed a significant difference in Economics learning outcomes between students taught using the Problem Based Learning (PBL) model assisted by Wayground media and those taught using the Discovery Learning model (Sig. = 0.000 < 0.05). In contrast, no significant differences were found in learning outcomes based on students’ learning interest (Sig. = 0.980 > 0.05), nor was there a significant interaction between the learning model and learning interest on students’ Economics learning outcomes (Sig. = 0.619 > 0.05). Therefore, the Problem Based Learning (PBL) model assisted by Wayground media resulted in better Economics learning outcomes than the Discovery Learning model, while learning interest and its interaction with the learning model did not significantly differentiate students’ learning outcomes.]]>
