Muhammad Abdillah Rizqi. (0900707). Pembelajaran Berbasis Masalah Berbantuan Cabri 3D untuk Meningkatkan Kemampuan Berpikir Kretaif Siswa SMP
Penelitian ini dilatarbelakangi oleh kemampuan berpikir kreatif siswa SMP yang masih rendah. Tujuan penelitian kuasi eksperimen ini adalah untuk mengetahui: 1) perbedaan peningkatan kemampuan berpikir kreatif antara siswa SMP yang mengikuti pembelajaran berbasis masalah berbantuan Cabri 3D dengan siswa SMP yang mengikuti pembelajaran konvensional, 2) respon siswa terhadap pembelajaran berbasis masalah berbantuan Cabri 3D. Indikator kemampuan berpikir Kreatif yang diukur dalam penelitian ini, yaitu : 1) Fluency (Keterampilan berpikir lancer); 2) Flexibility (keterampilan berpikir luwes); 3) Originality (Keterampilan berpikir orisinal); dan 4) Elaboration (Keterampilan memerinci). Populasi dalam penelitian ini adalah seluruh siswa kelas VIII SMP Negeri 1 Lembang. Sementara sampel dipilih tidak secara acak, melalui teknik purposif yang didasarkan pada pertimbangan peneliti dan guru, maka terpilih kelas VIII C sebagai kelas eksperimen  dan kelas VIII B sebagai kelas Kontrol. Pokok bahasan yang dijadikan bahan ajar adalah bangun ruang meliputi kubus dan balok. Instrumen yang digunakan adalah tes kemampuan berpikir kreatif, angket siswa, jurnal harian, dan lembar observasi. Berdasarkan analisis pada keseluruhan tahapan penelitian dapat disimpulkan bahwa: 1) peningkatan kemampuan berpikir kreatif siswa SMP melalui pembelajaran berbasis masalah berbantuan Cabri 3D lebih baik daripada peningkatan kemampuan berpikir kreatif siswa SMP melalui pembelajaran konvensional; 2) Siswa memberikan respon yang positif terhadap penerapan pembelajaran berbasis masalah berbantuan Cabri Cabri 3D.

Kata kunci: Pembelajaran Berbasis Masalah, Cabri 3D, Kemampuan Berpikir Kreatif.

ABSTRACT
Muhammad Abdillah Rizqi. (0900707). Problem based learning with Cabri 3D helping to increase junior high school student’s creative thinking ability
This study has the lack of creative thinking ability of junior high school students as the background. Therefore, the purposes of this quasi-experimental research are: 1) to know the difference between the creative thinking ability of Junior high school students who got problem based learning with Cabri 3D helping, and those who got conventional learning, 2) to know the response of the students towards problem based learning with Cabri 3D helping.
The indicators of creative thinking ability measured in this study were: 1) fluency (fast thinking skill), 2) flexibility (flexible thinking skill), 3) originality (original thinking skill), and 4) elaboration (detailed thinking skill). The population of this study is all the VIII graders of junior high school 1 Lembang, while the sample were not chosen randomly through purposive technique based on the researcher and teacher’s consideration. As the result, class VIII C was chosen as the experimental class and class VIII B was chosen as the control one.
The learning material used in this study was about 3D model like cube and bar. The instruments used in this study were creative thinking ability test, student questionnaire, daily journal, and observation sheet. Based on the analysis of the whole research steps, it could be concluded that: 1) the development of student’s creative thinking ability through problem based learning with Cabri 3D helping was better than those with conventional learning; 2) the students gave positive response to the application of problem based learning with Cabri 3D helping.

Key words: problem based learning, Cabri3D, creative thinking ability.
