Pengembangan E-LKPD Model Problem Based Learning Materi Ekosistem Untuk Melatih Keterampilan Berpikir Kritis Siswa Kelas X SMA

Development Of E-LKPD Problem Based Learning Model Ecosystem Material To Train Critical Thinking Skills in Class X Of High School Students

Kemampuan berpikir kritis menjadi aspek krusial bagi masyarakat di era global saat ini. Penelitian yang dilaksanakan berupa penelitian pengembangan yang memiliki tujuan untuk mengembangkan lembar kerja peserta didik elektronik (E-LKPD) model pembelajaran problem based learning dalam materi ekosistem pada untuk melatih keterampilan berpikir kritis siswa kelas X SMA yang layak dengan mengacu terhadap validitas, kepraktisan, dan keefektifan. Rancangan penelitian mengikuti model 4-D yang memuat tahapan define, design, develop, dan dessiminate. Penelitian ini menggunakan parameter validitas, kepraktisan, dan keefektifan berupa lembar validasi, lembar keterlaksanaan, lembar angket respons guru dan peserta didik dan lembar pre-test dan post-test. Uji coba penelitian ini dilaksanakan kepada 20 siswa kelas X 11 di SMA Negeri 2 Sidoarjo. Hasil penelitian menunjukkan E-LKPD dihasilkan validitas sangat valid dengan nilai 89%, dinyatakan praktis dengan perolehan keterlaksanaan sangat praktis dengan nilai 95,94% dan respons guru 95% serta respons peserta didik 96% kemudian dinyatakan sangat efektif dengan mengacu hasil ketuntasan belajar peserta didik yang berpedoman pada KKTP (Kriteria Ketercapaian Tujuan Pembelajaran) dengan nilai 100% serta ketercapaian keterampilan berpikir kritis kategori tinggi melalui perolehan n-gain 0,75. Berdasarkan penelitian tersebut, E-LKPD model problem based learning materi ekosistem untuk melatih keterampilan berpikir kritis siswa kelas X SMA dinyatakan valid, praktis dan efektif untuk dimanfaatkan sebagai bahan ajar dalam melatih keterampilan siswa untuk berpikir kritis.

The ability to think critically is a crucial aspect for society in the current global era. The research carried out is in the form of development research which aims to develop an electronic student worksheet (E-LKPD) problem based learning model in ecosystem material to train appropriate critical thinking skills for class X high school students with reference to validity, practicality and effectiveness. . The research design follows the 4-D model which contains the stages define, design, develop, and disseminate. This research uses validity, practicality and effectiveness parameters in the form of validation sheets, implementation sheets, teacher and student response questionnaire sheets and pre-test and post-test sheets. This research trial was carried out on 20 class X 11 students at SMA Negeri 2 Sidoarjo. The research results showed that the E-LKPD produced very valid validity with a score of 89%, was declared practical with very practical implementation with a score of 95.94% and a teacher response of 95% and a student response of 96%, then it was declared very effective by referring to the results of the students' learning completion. which is guided by the KKTP (Learning Goal Achievement Criteria) with a score of 100% and achieving high category critical thinking skills through an n-gain of 0.75. Based on this research, the E-LKPD problem based learning model of ecosystem material for training critical thinking skills for class X SMA students was declared valid, practical and effective to be used as teaching material in training students' critical thinking skills.
