Pengembangan E-book Interaktif Berbasis Problem Based Learning Pada Materi Pemanasan Global dan Perubahan Iklim untuk Melatihkan Keterampilan Berpikir Kritis Peserta Didik

Development of Interactive E-book Based on Problem Based Learning on Global Warming and Climate Change Materials to Train Students' Critical Thinking Skills

Penelitian ini bertujuan untuk menganalisis kevalidan dan kepraktisan e-book interaktif berbasis Problem Based Learnign untuk melatihkan keterampilan berpikir kritis peserta didik pada materi Pemanasan Global dan Perubahan Iklim. Metode yang digunakan dalam penelitian ini adalah Research and Development (R&D) dengan menggunakan desain penelitian dan pengembangan ADDIE (Analysis, Design, Development, Implementation, Evaluation). Uji coba terbatas menggunakan e-book interaktif berbasis PBL dilakukan pada peserta didik kelas X-3 SMA Muhammadiyah 1 Taman dengan sampel sebanyak 12 peserta didik. Teknik pengumpulan data yang digunakan dengan validasi, angket respon peserta didik, analisis penilaian soal indikator berpikir kritis, dan analisis ketercapaian peserta didik melatihkan keterampilan berpikir kritis. Proses validasi dilakukan oleh tiga validator untuk menilai e-book interaktif berbasis PBL. Penelitian ini memperoleh skor rata-rata kevalidan e-book interaktif berbasis PBL sebesar 92% dengan kriteria sangat valid. Setelah e-book interaktif dinyatakan valid, dilakukan implementasi untuk menganalisis kepraktisan e-book interaktif berbasis PBL. Kepraktisan ditinjau dari angket respon respon peserta didik yang memperoleh skor rata-rata sebesar 89,32% dengan kategori sangat praktis. Keefektifan pembelajaran menggunakan e-book berbasis argumentasi ilmiah dianalisis. Dilakukan analisis jawaban tiap soal indikator berpikir kritis yang mana diperoleh hasil rata-rata dari seluruh persentase indikator adalah sebesar 84% termasuk dalam kategori sangat baik sehingga soal yang diberikan terbukti berhasil melatihkan keterampilan berpikir kritis . Kemudian dilakukan analisis ketercapaian indikator keterampilan berpikir kritis pada peserta didik. Dimana diperoleh 75% peserta didik yang termasuk dalam kategori tercapai dan 25% dalam kategori tidak tercapai dimana secara penilaian skor klasikal di nyatakan sudah mengalami ketercapaian.

This study aims to analyze the validity and practicality of an interactive e-book based on Problem-Based Learning to develop critical thinking skills among students on the topic of global warming and climate change. The method used in this study is Research and Development (R&D) using the ADDIE (Analysis, Design, Development, Implementation, Evaluation) research and development design. A limited trial using the PBL-based interactive e-book was conducted on 12 students in class X-3 at Muhammadiyah 1 Taman High School. Data collection techniques used included validation, student response questionnaires, analysis of critical thinking indicator assessment questions, and analysis of students' achievement in developing critical thinking skills. The validation process was conducted by three validators to assess the interactive e-book based on PBL. This study obtained an average validity score of 92% for the interactive e-book based on PBL, meeting the criteria for high validity. After the interactive e-book was declared valid, implementation was carried out to analyze the practicality of the PBL-based interactive e-book. Practicality was reviewed through student response questionnaires, which obtained an average score of 89.32%, categorized as highly practical. The effectiveness of learning using e-books based on scientific argumentation was analyzed. An analysis of the answers to each critical thinking indicator question was conducted, yielding an average result of 84% for all indicator percentages, which falls into the “very good” category, indicating that the questions provided successfully trained critical thinking skills. An analysis of the achievement of critical thinking skill indicators among students was then conducted. It was found that 75% of students were categorized as having achieved the indicators, while 25% were categorized as not having achieved them. However, based on classical scoring, it was stated that the indicators had been achieved.
