PENERAPAN PROBLEM BASED LEARNING DENGAN PENUGASAN PETA KONSEP UNTUK MENINGKATKAN KETERAMPILAN BERPIKIR KREATIF PESERTA DIDIK PADA MATERI ALAT OPTIK

Keterampilan bepikir kreatif merupakan salah satu keterampilan abad 21 yang ingin dicapai oleh pemerintah melalui implementasi pembelajaran disekolah. Penelitian ini bertujuan untuk menguji efektivitas model problem based learning dengan penugasan peta konsep untuk meningkatkan keterampilan berpikir kreatif peserta didik. Desain penelitian ini adalah quasi-experimental, dengan 68 peserta didik kelas XI MIPA di salah satu sekolah di Kabupaten Bandung Barat. Instrumen penelitian ini berupa tes keterampilan berpikir kreatif sebanyak 5 soal uraian. Data penelitian yang diperoleh berupa data kuantitatif dari hasil pretest dan posttest . Hasil pretest dan posttest peserta didik diuji perbedaannya antara kelas kontrol dan kelas eksperimen menggunakan Mann-Whitney U Test. Kemudian peningkatan skor keterampilan berpikir kreatif peserta didik dihitung dengan menggunakan uji normalitas gain , sedangkan tingkat efektivitas pembelajaran kedua kelas akan dihitung dengan menggunakan effect size. Hasil pengolahan data menunjukan terdapat perbedaan keterampilan berpikir kreatif yang signifikan antara kelas kontrol dan kelas eksperimen. Peningkatan ketermpilan berpikir kreatif kelas eksperimen dan kelas kontrol berada pada kategori yang sama yaitu kategori sedang. Penerapan model problem based learning dengan penugasan peta konsep dapat meningkatkan keterampilan berpikir kreatif peserta didik dan mempunyai dampak yang cukup tinggi terhadap peningkatan keterampilan berpikir kratif peserta didik. Penerapan model problem based learning dengan penugasan peta konsep lebih efektif dalam meningkatkan keterampilan berpikir kreatif peserta didik. Kata Kunci: problem based learning, peta konsep, keterampilan berpikir kreatif. Creative thinking skills are one of the 21st-century skills that the government wants to achieve through the implementation of learning in schools.. This study aims to test the effectiveness of the problem based learning model with the assignment of concept maps to improve students' creative thinking skills. The design of this research is quasi-experimental, with 68 students of class XI MIPA in one of the schools in West Bandung Regency. The instrument of this research is in the form of a creative thinking skill test with as many as 5 description questions. Research data is obtained in the form of quantitative data from the results of the pretest and posttest. The results of the students' pretest and posttest were tested for differences between the control class and the experimental class using the Mann-Whitney U Test. Then the increase in the score of student's creative thinking skills is calculated using the gain normality test while the level of learning effectiveness of the two classes will be calculated using the effect size. The results of data processing showed that there were significant differences in creative thinking skills between the control class and the experimental class. The increase in creative thinking skills in the experimental class and the control class has a same category medium. The application of the problem based learning model with the assignment of concept maps can improve students' creative thinking skills and have a fairly high impact. The application of the problem based learning model with the assignment of concept maps is more effective in improving students' creative thinking skills..
