Program Studi Pendidikan Sains, Pascasarjana Universitas Negeri Surabaya. Pembimbing: (1) Dr. Wahono Widodo, M.Si. (2) Dr.  Sifak Indana, M.Pd.

Penelitian ini bertujuan untuk menghasilkan perangkat pembelajaran model Case Based Learning (CBL) yang layak ditinjau dari segi kevalidan, kepraktisan, dan keefektifan untuk melatihkan keterampilan penalaran ilmiah (scientific reasoning) peserta didik. Penelitian ini menggunakan pengembangan model four D (4D) dengan tahapan pendefinisian (define), perencanaan (design), pengembangan (develop), dan penyebaran (disseminate). Perangkat yang telah dikembangkan kemudian divalidasi oleh tiga orang validator yang terdiri dari dua dosen FMIPA Universitas Negeri Surabaya dan satu guru di sekolah. Tahap implementasi dilakukan pada peserta didik kelas X di SMAN 2 Pare menggunakan rancangan one group pretest-posttest design. Berdasarkan hasil penelitian, dapat disimpukan bahwa perangkat pembelajaran dengan model Case Based Learning (CBL) yang dikembangkan valid, praktis, dan efektif untuk meningkatkan keterampilan penalaran ilmiah peserta didik SMA Negeri 2 Pare pada materi gerak lurus. Perangkat pembelajaran dinyatakan sangat valid. Selain itu, perangkat dinyakatan praktis, ditinjau dari keterlaksanaan RPP dengan kategori sangat baik dan aktivitas peserta didik pada ketiga pertemuan dengan kategori sangat baik, namun terdapat beberapa kendala selama proses pembelajaran. Kemudian perangkat pembelajaran dinyakatan efektif ditinjau dari keterampilan penalaran ilmiah pada kelas X – 5, X – 6, dan X – 7 yang mengalami peningkatan kategori sedang, serta rata-rata respon peserta didik pada ketiga kelas dengan kateori sangat baik. Berdasarkan analisis data, dapat disimpulkan bahwa perangkat pembelajaran yang dikembangkan layak digunakan untuk melatihkan keterampilan penalaran ilmiah peserta didik.

Devian Astika Wati, 2023. Development of Learning Devices with The Case Based Learning (CBL) Model to Train High School Students' Scientific Reasoning Skills. Proposal. Science Education Study Program, Postgraduate Program at Surabaya State University. Advisor: (1) Dr. Wahono Widodo, M.Si. (2) Dr. Sifak Indana, M.Pd.

This study aims to produce learning tools for the Case Based Learning (CBL) model that are feasible in terms of validity, practicality, and effectiveness to train students' scientific reasoning skills. This study uses the development of the four D (4D) model with the stages of defining, planning, developing, and disseminating. The tools that have been developed are then validated by three validators consisting of two lecturers at the Faculty of Mathematics and Natural Sciences, Surabaya State University and one teacher at the school. The implementation phase was carried out for class X students at SMAN 2 Pare using the one group pretest-posttest design. Based on the results of the research, it can be concluded that device learning using the Case Based Learning (CBL) model developed is valid, practical, and effective for improving the scientific reasoning skills of SMA Negeri 2 Pare students in straight motion material. The learning device is stated to be very valid. In addition, the device is said to be practical, in terms of the implementation of the lesson plan in the very good category and the activities of the students at the third meeting in the very good category, but there are several obstacles during the learning process. Then the learning tools were said to be effective in terms of scientific reasoning skills in classes X-5, X-6, and X-7 which experienced an increase in the moderate category, as well as the average response of students in the third class with the very good category. Based on data analysis, it can be interpreted that the developed learning tools are suitable for training students' training skills.
