Abstract

Penelitian ini bertujuan untuk menganalisis pengaruh model pembelajaran Numbered Head Together (NHT) terhadap motivasi belajar siswa pada materi Masalah Lingkungan di SMAN 70 Jakarta. Penelitian ini termasuk ke dalam metode penelitian kuasi eksperimen (quasi experimental) dengan desain Nonequivalent Control Group Design. ampel penelitian dipilih menggunakan teknik purposive sampling, yaitu kelas XI Geo 3 sebagai kelas eksperimen yang menerapkan model Numbered Head Together (NHT) dan kelas XI Geo 2 sebagai kelas kontrol yang menggunakan pembelajaran konvensional atau Teacher centered. Data dikumpulkan menggunakan angket motivasi belajar yang terdiri atas 25 pernyataan dan diberikan sebelum (pretest) serta sesudah (posttest) pembelajaran. Pengujian dalam penelitian ini menggunakan teknik uji instrument, uji prasyarat, dan uji hipotesis. Hasil penelitian menunjukkan terdapat peningkatan motivasi belajar siswa pada kelas eksperimen setelah penerapan model Numbered Head Together (NHT). Rata-rata skor motivasi belajar kelas eksperimen meningkat dari 102,82 menjadi 105,96, sedangkan kelas kontrol menurun dari 100,86 menjadi 99,86. Hasil ini dibuktikan dengan hasil uji hipotesis yang menunjukkan nilai signifikansi (Sig.) sebesar 0,032 (<0,05), sehingga H₀ ditolak dan H₁ diterima. Hasil tersebut menunjukkan bahwa penerapan model pembelajaran Numbered Head Together (NHT) mampu meningkatkan motivasi belajar siswa melalui keterlibatan aktif, kerja sama kelompok, dan tanggung jawab individu dalam proses pembelajaran. Meskipun demikian, peningkatan motivasi belajar juga dimungkinkan dipengaruhi oleh faktor lain, seperti karakteristik siswa, materi pembelajaran, serta kondisi lingkungan belajar. ***** This study aims to analyze the effect of the Numbered Heads Together (NHT) learning model on students’ motivation to learn about environmental issues at SMAN 70 Jakarta. This study employs a quasi-experimental research method with a Nonequivalent Control Group Design. The research sample was selected using purposive sampling: Class XI Geo 3 served as the experimental class implementing the Numbered Head Together (NHT) model, while Class XI Geo 2 served as the control class using conventional, teacher-centered instruction. Data were collected using a learning motivation questionnaire consisting of 25 statements, administered before (pretest) and after (posttest) instruction. The analysis in this study employed instrument validation, prerequisite testing, and hypothesis testing. The results indicate an increase in students’ learning motivation in the experimental class following the implementation of the Numbered Head Together (NHT) model. The average learning motivation score for the experimental class increased from 102.82 to 105.96, while that of the control class decreased from 100.86 to 99.86. These results were supported by the hypothesis test, which yielded a significance value (Sig.) of 0.032 (<0.05), leading to the rejection of H₀ and acceptance of H₁. These results indicate that the implementation of the Numbered Head Together (NHT) learning model is capable of increasing students’ learning motivation through active engagement, group cooperation, and individual responsibility in the learning process. Nevertheless, the increase in learning motivation may also be influenced by other factors, such as student characteristics, learning materials, and the learning environment.
