The Development Learning Tools of Blended Learning by Integrating Discovery Learning of Human Respiratory System Topic to Practice Critical Thinking Skills for High School Students

Penelitian ini bertujuan untuk menghasilkan perangkat pembelajaran blended learning dengan mengintegrasikan discovery learning yang layak untuk melatih keterampilan berpikir kritis siswa SMA pada materi sistem pernapasan pada manusia. Pengembangan perangkat menggunakan model 4D yang diujicobakan pada siswa kelas XI SMA semester genap tahun pelajaran 2021/2022. Rancangan penelitian yang digunakan adalah one group pretest posttest design. Data penelitian yang dihasilkan adalah kevalidan, kepraktisan dan keefektifan perangkat pembelajaran yang dianalisis secara deskriptif kuantitatif dan kualitatif. Hasil penelitian menunjukkan bahwa (a) perangkat pembelajaran yang dikembangkan berkategori sangat valid, (b) kegiatan pembelajaran terlaksana dengan kategori sangat baik dengan rata-rata skor keterlaksanaan RPP pada sesi pembelajaran online 3,98 dan rata-rata skor keterlaksanaan RPP pada sesi pembelajaran offline 3,98, (c) aktivitas siswa dalam pembelajaran terlaksana sangat baik, (d) respon siswa terhadap pembelajaran blended learning dengan mengintegrasikan discovery learning sangat baik dengan persentase 96%, (e) hasil tes berpikir kritis siswa mengalami peningkatan yang tinggi, keterampilan berpikir kritis meningkat dari 34 (Kurang Terampil) menjadi 87 (Terampil). Simpulan pengembangan perangkat blended learning dengan mengintegrasikan discovery learning yang dikembangkan dinyatakan layak digunakan untuk melatih keterampilan berpikir kritis siswa pada materi sistem pernapasan pada manusia.

This study aims to produce a learning tool of blended learning by integrating discovery learning that is suitable for practice critical thinking skills of senior high school students on the human respiratory system topic. The development of the device using a 4D model was tested on XI grade students in the even semester of the 2021/2022 academic year. The research design used was one group pretest posttest design. The research data resulted were the validity, practicality, and effectiveness of the learning tools which are analyzed descriptively quantitative and qualitative. The results showed that (a) the learning tools developed were categorized as very valid, (b) learning activities were carried out in a very good category with an average online learning lesson plans implementation score of 3,98 and an average offline learning lesson plan implementation score of 3,98, (c) students activities in learning were carried out very well, (d) student responses to blended learning by integrating discovery learning were very good with a percentage of 96%, (e) the results of students' critical thinking test had a high increase, critical thinking skills increased from 34 (Less Skilled) to 87 (Skilled). The conclusion is the development of blended learning tools by integrating discovery learning which was developed is appropriate to be used to train students' critical thinking skills on the human respiratory system topic.
