Abstract

This study aims to analyze the need to develop a Problem-Based Learning (PBL)-based mathematics instructional design to improve the mathematical communication skills of eighth-grade junior high school students. The study employed a descriptive approach and involved 31 eighth-grade students and a mathematics teacher at SMPN 2 Jakarta. Data were collected through observation, a mathematical communication skills test, a questionnaire, and interviews. The results of the study indicate that students’ mathematical communication skills remain low, particularly in constructing mathematical models, representing ideas in graphs, and explaining solutions in their own words. The average test score of 20.11 indicates that most students have not yet met the expected proficiency indicators. Furthermore, instruction remains teacher-centered, resulting in students being less active in communicating mathematical ideas. The results of the curriculum and conceptual analysis identified “Equations of Straight Lines” as a suitable topic to be developed through PBL-based instructional design. Thus, the results of this needs analysis serve as the basis for designing an instructional approach capable of facilitating the improvement of students’ mathematical communication skills.

Abstract

Penelitian ini bertujuan menganalisis pengaruh pembelajaran berdiferensiasi terhadap kemampuan pemahaman matematis konsep pecahan ditinjau dari tingkat motivasi belajar siswa kelas V sekolah dasar. Latar belakang penelitian adalah rendahnya pemahaman siswa terhadap pecahan, sebagaimana ditunjukkan hasil AKM dan tes sumatif di Kabupaten Karawang, di mana lebih dari 60% siswa masih berada di bawah standar. Metode penelitian yang digunakan adalah kuantitatif dengan pendekatan kuasi eksperimen desain pretest-posttest non-equivalent control group, melibatkan 80 siswa kelas V SDN Duren III yang terbagi ke dalam kelas eksperimen (40 siswa) dengan pembelajaran berdiferensiasi berbasis gaya belajar (visual, auditori, kinestetik) dan kelas kontrol (40 siswa) dengan pembelajaran konvensional. Instrumen penelitian meliputi tes pemahaman matematis, kuesioner motivasi belajar, lembar observasi, dan pedoman wawancara yang telah teruji validitas isi (Gregory = 1,0) serta reliabilitas (Cronbach Alpha 0,452–0,566). Analisis data menggunakan uji-t dan ANOVA dua arah. Temuan penelitian menegaskan bahwa pembelajaran berdiferensiasi memberikan peningkatan signifikan pada pemahaman konsep pecahan dibandingkan pembelajaran konvensional (p < 0,05), dengan kenaikan nyata pada seluruh rentang kemampuan siswa. Analisis ANOVA menunjukkan tidak adanya interaksi antara pembelajaran dan motivasi belajar, yang berarti diferensiasi efektif bagi siswa bermotivasi tinggi, sedang, maupun rendah. Dengan karakter adaptif-inklusifnya, strategi ini direkomendasikan sebagai pendekatan instruksional yang dapat diterapkan secara luas untuk memperkuat numerasi siswa sekolah dasar.

Abstract

This study aims to identify students’ difficulties in solving Two-Variable Linear Equation System (SPLDV) problems in terms of their computational thinking skills and levels of self-confidence. The study incorporates four indicators of computational thinking combined with students’ self-confidence levels to examine their patterns of difficulty more comprehensively. A qualitative case study approach was employed, involving two ninth-grade students from MTsN Muaradua who were selected based on the results of a self-confidence questionnaire and a computational thinking test. Data were collected through questionnaires, written tests, and semi-structured interviews. The findings show that students with high self-confidence were able to solve SPLDV problems across all four indicators through logical, reflective, and systematic steps. In contrast, students with low self-confidence experienced difficulties at the abstraction stage and particularly at the generalization stage when required to formulate a general equation from the obtained results. Low self-confidence led to hesitation in connecting relationships between variables and hindered reflective thinking. These findings indicate the need to strengthen affective aspects alongside the development of computational thinking in SPLDV learning.

Abstract

A preliminary study in a junior high school revealed that students mathematical critical thinking skills in linear equations remain low, marked by learning barriers dominated by concrete-arithmetic reasoning. This study aims to develop a draft instructional design based on Problem-Based Learning (PBL) specifically formulated to stimulate the four indicators of Facione’s critical thinking framework regarding the concept of pure slope. The method used was instructional design research based on the Instructional Development Model (IDM) by Suparman and was limited to the stage of designing the initial draft product. This design was integrated with the “Future Savings” financial context within the worksheets. The results showed that each designed PBL syntax successfully mapped activities that stimulated critical thinking in a systematic manner. The “interpretation” indicator was triggered through problem orientation; “analysis” through the organization of tabular data; a combination of “analysis” and “evaluation” through the investigation of the  ratio in graphs; “inference” through the formal derivation of the gradient value (m); and “evaluation” through visual challenge questions. The study concludes with an initial draft of instructional design designed to serve as a theoretical basis for bridging students’ transition toward formal algebraic reasoning.
