Abstract

Mathematical problem-solving skills are competencies required by students to face challenges both in academic settings and real-life situations. However, based on observations, these skills are still considered low, including at SMPIT Rabbani in Bengkulu City. The research was conducted to examine the effect of implementing the CORE model on the mathematical problem-solving abilities of eighth-grade students at SMPIT Rabbani, Bengkulu City, using the topic of linear equations. The research design used is a quasi-experimental design, with an experimental group of 13 students applying the CORE model, and a control group of 13 students applying the conventional method. Data analysis showed a significance value (2-tailed) of 0.048 (0.05) with a Cohen’s d value of 0.85, indicating a significant impact with a large effect size. Finding of the search suggest that students who were taught using the CORE model demonstrated better problem-solving abilities than those taught using the conventional method, thus proving that this model is effective in improving students' mathematical problem-solving skills.

Abstract

The ability to answer mathematical issues gave pupils the chance to use it to overcome obstacles in everyday life as well as in the fields of mathematics and other sciences. A method known as Realistic Mathematics Education (RME) connected mathematical difficulties to pertinent real-world concerns. The purpose of this study was to ascertain whether the RME approach had an impact on the eighth-grade students at SMP Negeri 03 in Bengkulu City's capacity to solve mathematical problems. A quasi-experimental design with a nonequivalent control group was the study methodology employed. The treatment (X) or learning with the RME approach was applied to the first group, while the other group received conventional learning or no treatment. The sample was chosen using the purposive sampling technique. The study's findings demonstrated that the use of the RME approach affected the students' capacity to solve mathematical problems, as evidenced by a sig. (2-tailed) value of 0.001 significance level (α) = 0.05 based on the independent sample t-test statistical test on the two sample classes. Additionally, the average N-Gain score obtained was 0.40, which was classified as a "moderate" increase in understanding. Thus, it could be concluded that the use of the RME approach had a positive impact on the improvement of students' mathematical problem-solving abilities.

Abstract

Tujuan dari penelitian ini yakni guna mengkaji pengaruh model pembelajaran Brain Based Learning (BBL) terhadap kemampuan pemahaman konsep matematika dan self regulation learning siswa. Metode penelitian yaitu quasi eksperimen. Pengambilan data dengan melalui tes tertulis. Data dianalisis melalui uji ANAKOVA. Sampel penelitian siswa kelas VII A dan VII B MTs Ja-alHaq Kota Bengkulu. Hasil penelitian: (1) terdapat pengaruh linear antara kovariat kemampuan awal dengan pemahaman konsep matematika sebesar 48,1%, (2) kemampuan awal juga berpengaruh secara linear terhadap self regulation learning sebesar 7,9%, (3) pembelajaran BBL memberikan pengaruh terhadap pemahaman konsep matematika sebesar 74,6%, (4) pembelajaran BBL berpengaruh terhadap self regulation learning sebesar 21,2%, (5) hasil pemahaman konsep matematika siswa lebih tinggi dengan BBL dibandingkan pembelajaran secara konvensional, dan (6) pencapaian self regulation learning siswa dalam pembelajaran BBL lebih baik dibandingkan dengan pembelajaran secara konvensional.
