Implementation of the Case Based Learning (CBL) Learning Model to Improve Critical Thinking Skills of Middle School Students on Vibration Material

Penelitian dengan judul Penerapan Model Pembelajaran Case Based Learning (CBL) untuk Meningkatkan Keterampilan Berpikir Kritis Siswa SMP pada Materi Getaran bertujuan untuk mendeskripsikan peningkatan keterampilan berpikir kritis peserta didik setelah diterapkan model pembelajaran Case Based Learning, mendeskripsikan keterlaksanaan model pembelajaran Case Based Learning, dan mendeskripsikan respon peserta didik setelah mengikuti pembelajaran menggunakan model pembelajaran Case Based Learning. Metode penelitian yang digunakan yaitu jenis penelitian kuantitatif dengan pendekatan pre-experimental design (one group pretest and posttest) dengan tujuan memberikan perlakuan pada satu kelompok eksperimen tanpa kelompok kontrol. Selanjutnya data tersebut dianalisis menggunakan gain ternormalisasi untuk melihat peningkatan pre-test dan post-test peserta didik. Hasil analisis diperoleh bahwa hasil tes keterampilan berpikir kritis peserta didik mengalami peningkatan sebesar 0,78 sehingga memperoleh kriteria tinggi. Keterlaksanaan pembelajaran model pembelajaran Case Based Learning (CBL) pada materi getaran pertemuan pertama dan kedua memiliki skor rata-rata 5 dengan kategori sangat baik. Respon peserta didik terhadap model pembelajaran Case Based Learning (CBL) pada materi getaran diterima sangat baik dan positif. Hal ini terbukti dari nilai perolehan rata-rata memperoleh persentase 14,06% pada skala 3, 38,87% pada skala 4, dan 47,07% pada skala 5 dengan persentase paling banyak yaitu pada skala 5 dengan kriteria sangat baik.

           The Research which the title is The Application of Case Based Learning (CBL) Learning Model to Improve Critical Thinking Skills of Middle School Students on Vibration Material aims to describe the improvement of students' critical thinking skills after applying CBL learning model, describe the implementation of CBL learning model, and describe the students' responses after participating in CBL learning model. The research method used in this study is quantitative research with a pre-experimental design approach (one group pretest and posttest) with the aim of providing treatment to one experimental group without a control group. Furthermore, the data was analyzed using normalized gain to see the increase in students' pre-test and post-test. The results of the analysis showed that the students' critical thinking skills test results increased by 0.78 so that they obtained the high criteria. The implementation of the Case Based Learning (CBL) learning model in the first and second meeting vibration material has an average score of 5 with a very good category. Student responses to CBL learning model on vibration material were received very well and positively. It was proves from the average acquisition value with percentage of 14.06% on a scale of 3, 38.87% on a scale of 4, and 47.07% on a scale of 5 with the highest percentage being on a scale of 5 with very good criteria.
