PENERAPAN MODEL PEMBELAJARAN KOOPERATIF TIPE NUMBERED HEAD TOGETHER (NHT) UNTUK MELATIHKAN KETERAMPILAN METAKOGNITIF SISWA PADA MATERI KOLOID KELAS XI SMA

Penelitian berikut memiliki tujuan untuk memberikan deskripsi tentang keterlaksanaan model pembelajaran, aktivitas siswa, serta keterampilan metakognitif siswa dengan model pembelajaran kooperatif tipe NHT pada materi koloid. Rancangan penelitian yang dipakai yakni One Shot Case Study, dengan sasaran penelitian 36 siswa kelas XI IPA 2 di salah satu Madrasah Aliyah di Gresik. Hasil penelitian memperlihatkan bahwasanya: 1) Persentase keterlaksanaan model pembelajaran kooperatif tipe NHT di tiap fase berturut-turut berjumlah 90%; 91,6%; 100%; 82,5%; 90%, 100% pada pertemuan pertama, di pertemuan kedua bertutur-turut 100%; 91,6%; 100%, 75%, 85%, 100% berkategori sangat baik. 2) Aktivitas siswa pada pertemuan 1 dan 2 yang mempunyai persentase dominan ialah siswa ketika melaksanakan percobaan (moitoring skills) dengan persentase rata-rata berjumlah 26,3% dan 27,03%. 3) Nilai keterampilan metakognitif siswa berdasar dari tes berbasis keterampilan metakognitif dalam dua pertemuan berturut-turut bagi planning skills 72,22%; 91,66%; monitoring skills 7,77%; 86,1%; evaluating skills 75%; 88,8%. Nilai tersebut didukung pula dengan nilai inventori metakognitif dalam dua pertemuan yakni planning skills 85,71%; 92,86%; monitoring skills 82,14%; 96,42%; evaluating skills 83,33%; 91,66%. Berdasar dari nilai yang didapatkan tersebut, pada segi klasikal ketermpilan metakognitif siswa mengalami peningkatan dan mampu terlatih secara baik.

The objective of this study is to describe the implementation of the learning models, student activities, and the practice of metacognitive skills using the NHT type cooperative learning model in the subject of colloid. The research methodology used in this study is "One Shot Case Study," with a total of 36 students from XI grade of Science-2 in one of the Madrasah Aliyah in Gresik as the subjects. The research findings are as follows: 1) The percentage of implementation of the NHT type cooperative learning model in each phase was 90%, 91.6%, 100%, 82.5%, 90%, and 100% respectively in the first meeting. In the second consecutive meeting, the percentages were 100%, 91.6%, 100%, 75%, 85%, and 100%, with a perfect category. 2 The student activities in the first and second meetings showed higher percentages during the conduction of experiments (monitoring skills), with average rates of 26.3% and 27.03% respectively. 3) The results indicated the values of metacognitive skills based on planning skills for the two meetings were 72.22% and 91.66% respectively, for monitoring skills were 7.77% and 86.1%, and for evaluating skills were 75% and 88.8%. These results were supported by the achievement of metacognitive inventory given in the first and second meetings, where planning skills were 85.71% and 92.86%, monitoring skills were 82.14% and 96.42%, and evaluating skills were 83.33% and 91.66% respectively. Generally, sudents can practice metacognitive skills and increase correctly.
