Populasi penelitian ini sebanyak 210 peserta didik, dan sampel sebanyak 81 peserta didik. Data hasil penelitian diperoleh dengan memberikan tes esai keterampilan berpikir kreatif pada materi pokok pemanasan global. Teknik analisis data menggunakan analisis deskriptif, analisis taksiran rata-rata dan analisis uji N-gain. Dari hasil analisis deskriptif didapatkan rata-rata hasil sebelum perlakuan adalah 9,10 dengan standar deviasi 1,96 dan varians sebesar 2,87 dan hasil setelah perlakuan didapatkan rata-rata skor 11,94 dengan standar deviasi 1,95 dan varians sebesar 3,81. Analisis taksiran rata-rata didapatkan rata-rata populasi sebelum perlakuan sebesar 8,72<µ<9,47 dan setelah perlakuan sebesar 11,48<µ<12,4. Analisis uji N-gain didapatkan peningkatan keterampilan berpikir kreatif peserta didik sebesar 0,43 dan temasuk dalam kategori sedang.

The population of this study was 210 students, and the sample was 81 students. The research data was obtained by giving an essay test on creative thinking skills on the main topic of global warming. Data analysis techniques use descriptive analysis, average estimate analysis and N-gain test analysis. From the results of the descriptive analysis, the average score before treatment was 9.10 with a standard deviation of 1.96 and a variance of 2.87 and the results after treatment obtained an average score of 11.94 with a standard deviation of 1.95 and a variance of 3. 81. Analysis of the average estimates showed that the population average before treatment was 8.72<µ<9.47 and after treatment was 11.48<µ<12.4. Analysis of the N-gain test showed that students' creative thinking skills increased by 0.43 and were included in the medium category.
