PENERAPAN MODEL PROBLEM BASED LEARNING BERBASIS LITERASI SAINS TERHADAP KETERAMPILAN BERPIKIR KRITIS PESERTA DIDIK SMP MATERI EKOSISTEM

IMPLEMENTATION OF PROBLEM BASED LEARNING BASED ON SCIENCE LITERACY TO IMPROVE STUDENTS’ CRITICAL THINKING SKILLS OF JUNIOR HIGH SCHOOL STUDENTS IN ECOSYSTEM MATERIALS

Hasil pra-penelitian menunjukkan bahwa keterampilan berpikir kritis peserta didik masih rendah. Upaya yang dirumuskan yaitu menerapkan model problem based learning (PBL) berbasis literasi sains. Model ini mendorong peserta didik untuk berpikir kritis, aktif, serta dapat mengembangkan kemampuan memecahkan masalah. Tujuan penelitian yaitu mendeskripsikan keterlaksanaan pembelajaran, keterampilan berpikir kritis, dan respons peserta didik setelah pembelajaran. Penelitian ini menggunakan desain pre-experimental dengan teknik one group pretest-posttest design. Subjek penelitian adalah peserta didik kelas VII E SMP Muhammadiyah 2 Taman sebanyak 28 orang. Hasil penelitian menunjukkan bahwa (1) keterlaksanaan pembelajaran dengan menerapkan model PBL berbasis literasi sains terlaksana sangat baik, (2) penerapan model PBL berbasis literasi sains dapat meningkatkan keterampilan berpikir kritis peserta didik, dengan perolehan N-gain sebesar 0.51 kategori sedang, dan (3) respons peserta didik terhadap penerapan model PBL berbasis literasi sains memperoleh rerata sebesar 76.87% dengan kategori baik. Simpulan yang diperoleh bahwa penerapan model PBL berbasis literasi sains dapat meningkatkan keterampilan berpikir kritis peserta didik. Adapun saran yang diajukan yaitu penerapan model PBL berbasis literasi sains dapat dilakukan secara kontinu, dan pembagian kelompok yang berisi 4-5 peserta didik agar setiap anggota berkontribusi secara maksimal.

Pre-research results show that students' critical thinking skills are still low. The formulated effort is to apply the problem-based learning (PBL) model based on science literacy. This model encourages students to think critically, be active, and develop problem-solving skills. The purpose of the study was to describe the implementation of learning, critical thinking skills, and students' responses after learning. This research used pre-experimental design with one group pretest-posttest design technique. The research subjects were 28 students of class VII E SMP Muhammadiyah 2 Taman. The results showed that (1) the implementation of learning by applying the science literacy-based PBL model was very well implemented, (2) the application of the science literacy-based PBL model could improve students' critical thinking skills, with the acquisition of N-gain of 0.51 medium category, and (3) students' responses to the application of the science literacy-based PBL model obtained an average of 76.87% in the good category. It is concluded that the application of PBL model based on science literacy can improve students' critical thinking skills. The suggestions proposed are the application of PBL models based on scientific literacy can be carried out continuously, and the division of groups containing 4-5 students so that each member contributes optimally.
