The Effect of Problem Based Learning and Open-Ended Learning on Mathematics Creative Thinking Ability: A Meta Analysis Study

This study aims to analyze the effect of Problem Based Learning (PBL) and Open Ended Learning (OEL) on the ability to think creative mathematically based on the effect size category, education level, and learning materials. This research method is a meta-analysis by reviewing several journals that have been published online. This study used 15 journals on PBL and 15 journals on OEL related to mathematical creative thinking skills. The instrument in this meta-analysis was carried out with a coding category sheet according to the research variables, namely: the year of the study, the title of the study, the level of education, the material used in the study, also the independent variable and dependent variable of study. The data analysis technique used is descriptive statistics. The results of the meta-analysis showed that PBL had a higher effect than OEL on students' mathematical creative thinking abilities. Based on the level of education, PBL has more influence on junior high school students, while OEL has more influence on students at high school level. In terms of learning materials, PBL has more influence on SPLDV material than other materials, while OEL has more influence on social arithmetic material.

Abstrak: Penelitian ini bertujuan untuk menganalisis pengaruh Problem Based Learning (PBL) dan Open Ended Learning (OEL) terhadap kemampuan berpikir kreatif matematis berdasarkan kategori effect size, jenjang pendidikan, dan materi pembelajaran. Metode penelitian ini adalah meta analisis dengan mengkaji beberapa jurnal yang sudah terpublikasi secara online. Penelitian ini menggunakan 15 jurnal tentang PBL dan 15 jurnal tentang OEL terkait kemampuan berpikir kreatif matematis. Instrumen penelitian berupa lembar pemberian kode (coding category) sesuai variabel penelitian yaitu: tahun penelitian, judul penelitian, jenjang pendidikan, materi yang digunakan dalam penelitian, serta variabel bebas dan variabel terikat penelitian. Teknik analisis data yang digunakan adalah statistik deskriptif. Hasil penelitian meta analisis menunjukkan bahwa PBL memberikan pengaruh yang lebih tinggi dibandingkan OEL terhadap kemampuan berpikir kreatif matematis siswa. Berdasarkan jenjang pendidikan, PBL lebih berpengaruh pada siswa jenjang SMP, sedangkan OEL lebih berpengaruh pada siswa jenjang SMA. Dari segi materi pembelajaran, PBL lebih berpengaruh pada materi SPLDV dibandingkan materi lainnya, sedangkan OEL lebih berpengaruh pada materi aritmetika sosial.
