Abstract

This developmental research aims to produce physics learning device using qualified Problem Based Learning model (PBL) (validity, practicality, and effectiveness) to practice students's critical thinking skills in the subject of rotational dynamics and the weight of the object point. This research was implemented into stages, namely device development using the 4-D model of Thiagarajan (1974) and learning device implementation for 4 meetings with 25 students of eleventh grade of the State senior high school 1 Muara Lawa, in the second semester the academic year 2014/2015 by using one group pretest-posttest design the results of the research was analyzed by using descriptive analysis techniques. The obtained data: validator assessment of the lesson plan (RPP), student’s worksheet (LKS), Student’s Books, and assessment sheets with valid category. Student’s worksheet assessment and student’s book also have a high degree of readability. Lesson plan feasibility with the score of 4.04 is well performed category. Student learning outcomes (knowledge, critical thinking skills, psychomotor skills and attitudes) is classically completed. All students got critical thinking improvement: 16% (not skillful-less skillfull), 48% (not skillful-skillful), 36% (not skillful-very skillful). Based on the observation 65% of the learning was student’s activity. The students responded the learning activities of PBL models positively.The research shows that the physics learning device using problem based learning model is valid, practical, and effective to train the students' critical thinking skills. Penelitian pengembangan ini bertujuan untuk menghasilkan perangkat pembelajaran fisika model Problem Based Learning (PBL) yang berkualitas (validitas, kepraktisan, dan keefektifan) untuk melatih keterampilan berpikir kritis siswa pada materi dinamika rotasi benda tegar dan titik berat benda. Penelitian ini dilaksanakan dalam dua tahap, yaitu pengembangan perangkat mengikuti rancangan 4-D model dari Thiagarajan (1974) dan dilanjutkan dengan tahap implementasi perangkat pembelajaran sebanyak 4 pertemuan terhadap 25 siswa kelas XI-IPA di SMA Negeri 1 Muara Lawa semester genap tahun pelajaran 2014/2015 dengan menggunakan rancangan one group pretest-posttest design sedangkan hasil penelitian dianalisis dengan teknik analisis deskriptif. Data hasil penelitian diperoleh: penilaian validator terhadap RPP, LKS, Buku Siswa, dan lembar penilaian dengan kategori valid. LKS dan Buku siswa juga memiliki tingkat keterbacaan yang tinggi. Penilaian keterlaksanaan RPP dengan skor 4,04 berkategori terlaksana dengan baik. Hasil belajar siswa (pengetahuan, keterampilan berpikir kritis, keterampilan psikomotor dan sikap) secara klasikal tuntas. Semua siswa mengalami peningkatan keterampilan berpikir kritis: 16% (tidak terampil-kurang terampil), 48% (tidak terampil-terampil), 36% (tidak terampil-sangat terampil). Hasil pengamatan sebesar 65% dari pembelajaran adalah aktivitas siswa. Siswa memberikan respon yang positif terhadap kegiatan pembelajaran model PBL. Hasil penelitian menunjukkan bahwa perangkat pembelajaran fisika dengan model PBL telah valid, praktis, dan efektif untuk melatih keterampilan berpikir kritis siswa.
