Pengembangan LKPD Berbasis Problem Based Learning Materi Perdagangan Internasional Untuk Meningkatkan Keterampilan Berpikir Kritis Peserta Didik Kelas VIII SMP Labschool Unesa 2

Development Of LKPD Based On Problem Based Learning International Trade Materials To Improve Critical Thinking Skills Of Class VIII Students Of Unesa 2 Labschool Junior High School

Keterampilan berpikir kritis merupakan salah satu skill yang dibutuhkan peserta didik dalam era abad ke 21. Keterampilan ini dapat diasah melalui metode dan sumber belajar yang tepat dalam pembelajaran. Namun kenyataannya, masih banyak kekurangan sumber belajar yang digunakan dan penggunaanya masih terbatas salah satunya dalam pembelajaran IPS. Penelitian ini bertujuan untuk mengembangkan LKPD berbasis Problem Based Learning untuk meningkatkan keterampilan berpikir kritis. Penelitian ini merupakan penelitian pengembangan (R&D) menggunakan model ADDIE terdiri 5 tahapan yaitu Analyze, Design, Development, Implementation, Evaluation. Penelitian ini menggunakan desain One Group Pretest-Posttest. Teknik pengumpulan data yang digunakan dalam penelitian adalah observasi, wawancara, kuisioner, dan tes. Analisis data menggunakan skoring kemudian dipersentasekan. Hasil dari penelitian ini menunjukkan bahwa: (1) LKPD berbasis Problem Based Learning untuk meningkatkan keterampilan berpikir kritis sangat layak digunakan dalam pembelajaran IPS berdasarkan penilaian oleh ahli media memperoleh persentase sebesar 87,05%, penilaian oleh ahli materi memperoleh persentase 83,33%, dan penilaian oleh praktisi pendidikan memperoleh persentase 87,69%. (2) LKPD berbasis Problem Based Learning cukup efektif untuk meningkatkan keterampilan berpikir kritis berdasarkan hasil pretest dan posttest melalui Uji Paired Sample T-Test memperoleh hasil Sig. (2 tailed) 0,000 < 0,05 yang artinya Ho ditolak dan Ha diterima dan Uji N-Gain memperoleh hasil 64.59% dengan kategori cukup efektif.

Kata Kunci : LKPD, Problem Based Learning, Keterampilan Berpikir Kritis

Critical thinking skills are one of the skills that students need in the 21st century era. This skill can be honed through appropriate learning methods and resources in learning. However, in reality, there are still many learning resources used and their use is still limited, one of which is in social studies learning. This research aims to develop LKPD based on Problem Based Learning to improve critical thinking skills. This research is development research (R&D) using the ADDIE model consisting of 5 stages, namely Analyze, Design, Development, Implementation, Evaluation. This research uses a One Group Pretest-Posttest design. Data collection techniques used in research are observation, interviews, questionnaires and tests. Data analysis uses scoring and then percentages. The results of this research show that: (1) LKPD based on Problem Based Learning to improve critical thinking skills is very suitable for use in social studies learning based on an assessment by media experts which obtained a percentage of 87.05%, an assessment by material experts obtained a percentage of 83.33%, and the assessment by educational practitioners obtained a percentage of 87.69%. (2) Problem Based Learning-based LKPD is quite effective in improving critical thinking skills based on pretest and posttest results through the Paired Sample T-Test, obtaining Sig. (2 tailed) 0.000 < 0.05, which means Ho is rejected and Ha is accepted and the N-Gain Test gets a result of 64.59% in the quite effective category.
