<![CDATA[Abstract: The purpose of this study was to determine the effect of teacher teaching style and learning facilities on student learning outcomes with active student participation as a moderating variable in the Economics subject of class XI of SMA Negeri 2 Percut Sei Tuan. The population in this study were all class XI students of SMA Negeri 2 Percut Sei Tuan, totaling 134 students. The research sample consisted of 101 students determined using proportional random sampling technique. The results of the study showed that: (1) teacher teaching style had a positive and significant effect on student learning outcomes as indicated by the calculated t value being greater than the t table with a significance value of 0.000 < 0.05; (2) learning facilities had a positive and significant effect on student learning outcomes as indicated by the calculated t value being greater than the t table with a significance value of 0.000 < 0.05; and (3) teacher teaching style and learning facilities simultaneously had a positive and significant effect on student learning outcomes as indicated by the calculated F value being greater than the F table with a significance value of 0.000 < 0.05. The coefficient of determination (R²) value indicates that variations in student learning outcomes can be explained by the teacher's teaching style and learning facilities, while the rest is influenced by other factors not examined in this study. In addition, the results of the Moderated Regression Analysis (MRA) show that active student participation is able to moderate the influence of the teacher's teaching style and learning facilities on student learning outcomes. Based on the results of the study, it can be concluded that the teacher's teaching style and learning facilities have a positive and significant influence both partially and simultaneously on student learning outcomes, and active student participation plays a role as a moderating variable in strengthening this relationship.

Populasi dalam penelitian ini adalah seluruh siswa kelas XI SMA Negeri 2 Percut Sei Tuan yang berjumlah 134 siswa. Sampel penelitian berjumlah 101 siswa yang ditentukan menggunakan teknik proportional random sampling. Hasil penelitian menunjukkan bahwa: (1) gaya mengajar guru berpengaruh positif dan signifikan terhadap hasil belajar siswa yang ditunjukkan oleh nilai t hitung lebih besar daripada t tabel dengan nilai signifikansi 0,000 < 0,05; (2) fasilitas belajar berpengaruh positif dan signifikan terhadap hasil belajar siswa yang ditunjukkan oleh nilai t hitung lebih besar daripada t tabel dengan nilai signifikansi 0,000 < 0,05; dan (3) gaya mengajar guru dan fasilitas belajar secara simultan berpengaruh positif dan signifikan terhadap hasil belajar siswa yang ditunjukkan oleh nilai F hitung lebih besar daripada F tabel dengan nilai signifikansi 0,000 < 0,05. Nilai koefisien determinasi (R²) menunjukkan bahwa variasi hasil belajar siswa dapat dijelaskan oleh gaya mengajar guru dan fasilitas belajar, sedangkan sisanya dipengaruhi oleh faktor lain yang tidak diteliti dalam penelitian ini. Selain itu, hasil Moderated Regression Analysis (MRA) menunjukkan bahwa partisipasi aktif siswa mampu memoderasi pengaruh gaya mengajar guru dan fasilitas belajar terhadap hasil belajar siswa. Berdasarkan hasil penelitian dapat disimpulkan bahwa gaya mengajar guru dan fasilitas belajar memiliki pengaruh positif dan signifikan baik secara parsial maupun simultan terhadap hasil belajar siswa, serta partisipasi aktif siswa berperan sebagai variabel moderasi dalam memperkuat hubungan tersebut.
