Penerapan Model Pembelajaran Kooperatif Tipe NHT Berbasis Blended Learning Untuk Meningkatkan Motivasi dan Hasil Belajar Peserta Didik Pada Materi Laju Reaksi

Implementation of the NHT Cooperative Learning Model Based on Blended Learning to Improve Student Motivation and Learning Outcomes on Reaction Rate Material

Penelitian ini memiliki tujuan yang diharapkan untuk menguraikan (1) keterlaksanaan model pembelajaran kooperatif tipe NHT berbasis blended learning, (2) aktivitas peserta didik, (3) motivasi belajar, (4) hasil belajar, dan (5) respon peserta didik. Jenis penelitian yang digunakan adalah pra-eksperimen dengan rancangan One Group Pretest-Posttest Design. Sasaran yang dituju adalah peserta didik kelas XI MIPA 2 di SMA Negeri 19 Surabaya. Hasil penelitian diperoleh (1) Keterlaksanaan model pembelajaran kooperatif tipe NHT berbasis blended learning diperoleh persentase pertemuan pertama sebesar 95,24% dan pertemuan kedua sebesar 98,81% dengan keduanya termasuk kategori sangat baik. (2) Aktivitas peserta didik sangat baik dengan persentase pada pertemuan I dan II adalah 98,53% dan 98,64%. (3) Peningkatan motivasi belajar sebelum dan sesudah diberikan model pembelajaran dengan persentase dari 74,88% menjadi 85,32%, (4) Peningkatan hasil belajar peserta didik dapat dilihat dari skor N-Gain sebesar 0,749 dengan kriteria tinggi. (5) Respon peserta didik dalam kategori sangat baik dengan persentase sebesar 95,83%. Simpulan penelitian ini yakni motivasi dan hasil belajar peserta didik pada materi laju reaksi mengalami peningkatan sebagai akibat dari penerapan model pembelajaran koopearatif tipe NHT.

The goals of this research were (1) the implementation of the NHT-based cooperative learning model based on blended learning, (2) student activities, (3) learning motivation, (4) learning outcomes, and (5) student responses. The type of research used is pre-experimental with One Group Pretest-Posttest Design. The intended target is students of class XI MIPA 2 at SMA Negeri 19 Surabaya. The results obtained (1) the implementation of the NHT cooperative learning model based on blended learning obtained the percentage of the first meeting of 95.24% and the second meeting of 98.81% with both included in the very good category. (2) The activity of the students was very good with the percentages at the first and second meetings being 98.53% and 98.64%. (3) An increase in learning motivation before and after being given a learning model with a percentage from 74.88% to 85.32%, (4) An increase in student learning outcomes can be seen from the N-Gain score of 0.749 with high criteria. (5) The response of students in the very good category with a percentage of 95.83%. The conclusion of this study is that the motivation and learning outcomes of students on the reaction rate material have increased as a result of the application of the NHT type cooperative learning model.
