IMPLEMENTASI MODEL PEMBELAJARAN PROBLEM BASED LEARNING UNTUK MENINGKATKAN KETERAMPILAN BERPIKIR KRITIS SISWA DENGAN KONTEKS SOCIO-SCIENTIFIC ISSUE

IMPLEMENTATION OF PROBLEM BASED LEARNING MODEL TO IMPROVE STUDENT'S CRITICAL THINKING SKILLS WITH SOCIO-SCIENTIFIC ISSUE CONTEXT

Penelitian ini bertujuan untuk mendeskripsikan keterlaksanaan pembelajaran, peningkatan keterampilan berpikir kritis, dan respons siswa terhadap penerapan model problem based learning berkonteks socio-scientific issue pada materi sumber energi. Jenis penelitian ini menggunakan pre-eksperimental design dengan one group pretest posttest design. Subjek dalam penelitian ini adalah 30 siswa kelas VII C SMPN 42 Surabaya. Teknik pengumpulan data dilakukan dengan observasi, pemberian tes awal dan akhir, serta pemberian angket. Data dianalisis secara deskriptif kuantitatif. Hasil penelitian menunjukkan bahwa keterlaksanaan pembelajaran memperoleh hasil dengan kategori sangat baik pada pertemuan pertama dan kedua. Keterampilan berpikir kritis efektif mengalami peningkatan dengan skor N-Gain kategori sedang. Siswa memberikan respons positif dan minat yang tinggi terhadap proses pembelajaran. Berdasarkan hasil tersebut, dapat disimpulan bahwa penerapan model problem based learning berkonteks socio-scientific issue dapat meningkatkan keterampilan berpikir kritis siswa.

This research aimed to describe the learning implementation of learning, improvement of critical thinking skills, and students’ response to the implementation of problem based learning model with socio-scientific issue on energy sources. This research used a pre-experimental design with one group pretest posttest design. The subject in this research were 30 students of VII C class in SMPN 42 Surabaya. Data were collected by observation, pretest and posttest, and questionnaires. The data was analyzed quantitatively. The research result showed that implementation of learning obtained high results with very good category in the first and second meeting. The critical thinking skills effectively improved with N-Gain score in medium category. The students gave a positive response and high interest in learning implementation. Based on the result, it can be concluded that implementation of problem based learning model with socio-scientific issue can improve students’ critical thinking skills.
