This type of research is quantitative research with an explanatory approach, which aims to explain the cause-and-effect relationship between these variables. The population in this study were all 102 class XI MPLB students. The sampling technique used non-probability sampling with a total sampling type, so that the entire population was sampled. Data collection was carried out by distributing questionnaires to students. The data obtained were then analyzed using SPSS version 27 software. Before conducting multiple linear regression analysis, validity and reliability tests were first conducted to ensure that the instruments used were appropriate and consistent in measuring the variables studied. The analysis results show that the three independent variables—learning interest, learning discipline, and critical thinking skills—have a significant influence on student learning outcomes. Therefore, it can be concluded that improvements in these three aspects will positively impact student learning outcomes in the subjects studied.
