Abstract

This experimental research with a quantitative approach will test several learning models on students' mathematical problem solving abilities. The models used are CTL and PBL. This study involved three sample classes including CTL, PBL and Direct Instruction classes. In each learning model, the differences between the three will be examined to see their influence on students' mathematical problem solving abilities. The quantitative analysis used is the Tukey test with a significance level of 0.981. Meanwhile, the direct learning model shows a significance value of 0.024, which means there is no significant influence. Thus, the PBL and CTL learning models have more influence on mathematical problem solving abilities than direct instruction.

Abstract

The low level of mathematical problem-solving skills among junior high school students necessitates effective heuristic-based instructional strategies. This quasi-experimental study, employing a pretest-posttest two-group design, aimed to compare the effectiveness of the Decomposing-Recombining (DR) and Working Backwards (WB) approaches on Linear Equations and Inequalities in One Variable. The research sample consisted of 49 eighth-grade students (DR: N=24, WB: N=25) in Muaro Jambi, selected through purposive sampling. Instruments included mathematical problem-solving tests and instructional observation sheets. Results indicated that the DR approach met all effectiveness criteria, achieving a post-test mean score of 78.47 and a high-category improvement (N-Gain significantly exceeding 0.70, p < 0.05). Conversely, the WB approach only reached a moderate improvement with a post-test mean of 53.72. The Mann-Whitney U test confirmed a significant difference in effectiveness between the two groups (Z = -4.091, p < 0.001), with the DR approach consistently outperforming WB in enhancing problem-solving abilities. This study concludes that the DR approach is a more effective explicit instructional strategy for strengthening students' conceptual and procedural mathematical structures. ABSTRAK Rendahnya kemampuan pemecahan masalah matematis murid SMP memerlukan alternatif strategi pembelajaran berbasis heuristik yang efektif. Penelitian quasi-experiment dengan pretest-posttest two-group design ini bertujuan membandingkan efektivitas pendekatan Decomposing-Recombining (DR) dan Working Backwards (WB) pada materi persamaan dan pertidaksamaan linear satu variabel (PLSV & PTLSV). Sampel penelitian terdiri dari 49 murid kelas VIII (DR: N=24, WB: N=25) di Muaro Jambi yang dipilih melalui purposive sampling. Instrumen penelitian meliputi tes kemampuan pemecahan masalah dan lembar observasi aktivitas pembelajaran. Hasil analisis menunjukkan bahwa pendekatan DR memenuhi seluruh kriteria efektivitas dengan skor rata-rata post-test sebesar 78,47 dan peningkatan (N-Gain) pada kategori tinggi (median signifikan dari 0,70, p < 0,05). Sebaliknya, pendekatan WB hanya mencapai peningkatan kategori sedang dengan rata-rata post-test 53,72. Uji Mann-Whitney U mengonfirmasi perbedaan signifikan efektivitas antar kedua kelompok (Z = -4,091, p < 0,001), di mana pendekatan DR secara konsisten mengungguli WB dalam meningkatkan kemampuan pemecahan masalah. Penelitian ini menyimpulkan bahwa pendekatan DR lebih efektif sebagai strategi instruksional eksplisit untuk memperkuat struktur konseptual dan prosedural matematis murid SMP.

Abstract

21st-century mathematics education demands students’ self-confidence in developing creative ideas; however, instructional practices remain teacher-centered, resulting in low student Creative Self-Efficacy (CSE). As a solution, a learning model that integrates creativity and collaboration through Creative Collaborative Mathematical Reasoning (CCMR) is required. This study aims to determine the effect of the CCMR model on the CSE of eighth-grade students at MTsN 1 Tanjung Jabung Barat. The research method employed was a quasi-experiment with a Non-Equivalent Control Group Design. The research population consisted of six classes, from which samples were selected using a purposive sampling technique based on an ANOVA equivalence test, resulting in class VIII A as the experimental group and class VIII B as the control group. The research instrument was a CSE questionnaire that had been tested for validity and reliability. Data analysis involved normality, homogeneity, and independent sample t-tests. The results showed a significant difference between the experimental and control classes, with a significance value of  and a  of  The average CSE of the experimental class was higher than that of the control class. Consequently, the CCMR learning model has a positive effect on increasing students’ Creative Self-Efficacy in mathematics21st-century mathematics education demands students’ self-confidence in developing creative ideas; however, instructional practices remain teacher-centered, resulting in low student Creative Self-Efficacy (CSE).
