PENERAPAN MODEL PEMBELAJARAN PROBLEM BASED LEARNING UNTUK MENINGKATKAN KEMAMPUAN BERPIKIR KRITIS PESERTA DIDIK

APPLICATION OF PROBLEM BASED LEARNING LEARNING MODEL TO INCREASE CRITICAL THINKING ABILITY OF STUDENTS

ABSTRAK

Penelitian tindakan kelas ini dilaksanakan dengan didasari oleh kurangnya berpikir kritis peserta didik yang memiliki dampak kepada hasil belajar. Penelitian ini bertujuan untuk meningkatkan kemampuan berpikir kritis peserta didik dengan menerapkan model pembelajaran Problem Based Learning. Jenis penelitian ini adalah penelitian tindakan kelas (PTK) dengan objek penelitian meningkatkan kemampuan berpikir kritis peserta didik dengan penerapan model pembelajaran Problem Based Learning pada materi APBN dan APBD dalam Pembangunan di kelas XI IIS 3 SMA Negeri 1 Puri Mojokerto.

Penelitian ini dilakukan dengan dua siklus. Masing-masing siklus menggunakan tahapan penelitian perencanaan (planning), pelaksanaan (acting), pengamatan (observing), dan refleksi (reflekting). Instrumen yang digunakan yaitu post-test untuk mengetahui kemampuan berpikir kritis dan lembar observasi untuk mengetahui aktivitas guru, aktivitas peserta didik dan respon peserta didik terhadap penerapan model Problem Based Learning. Hasil dari penelitian ini yaitu kemampuan berpikir kritis peserta didik meningkat dari siklus 1 sebesar 50%  menjadi 87,5% pada siklus 2, aktivitas guru menunjukkan kenaikan dari siklus 1 sebesar 78,94%  menjadi 92,63% pada siklus 2, aktivitas peserta didik mengalami peningkatan 78,57% pada siklus 1 menjadi 85,71% pada siklus 2, dan respon peserta didik sebesar 89,06%. Kesimpulan dari hasil tersebut yaitu penerapan model Problem Based Learning dapat meningkat kemampuan berpikir kritis peserta didik.

ABSTRACT

The classroom action research is based on lack of student critical thinking skill has an impact result of learning. This study aims to improve students critical thinking skills by applying Problem Based Learning model. The type of this study is classroom action research (CAR) that is applied to eleventh grade of Social Major 3 in SMA Negeri 1 Puri Mojokerto by applying the Problem Based Learning model to the APBN and APBD materials in Development.

This study was conducted in two cycles. Each cycle uses the stages of study plan (planning), implementation (acting), observation (observing), and reflection (reflecting). The instruments used were a post-test to determine the ability to think critically and an observation sheet to find out the teacher's activities, the students activities and students responses to the application of Problem Based Learning model. The result showed that the students critical thinking skills increased from 50% in cycle 1 to 87.5% in cycle 2. Furthermore, the teacher activity showed an increase from 78.94% in cycle 1 to 92.63% in cycle 2. While the students activity also experienced an increase from 78.57% in cycle 1 to 85.71% in cycle 2, and the students response reached 89.06%. Therefore, it can be concluded that based on the results, the application of Problem Based Learning model can increase students critical thinking skills.
