Abstract

Learning exponent concepts remains challenging for middle school students, particularly in developing problem-solving skills. This study aimed to examine the effectiveness of the MathShark game-based application integrated with a STEM approach compared to conventional mathematics instruction. A quasi-experimental design with a pretest–posttest control group was employed. The participants consisted of two groups of middle school students: an experimental group using the MathShark application and a control group receiving traditional instruction. Data were collected through problem-solving tests and analyzed using the Mann–Whitney U test and the Wilcoxon Signed-Rank test. The results indicated a significant improvement in students’ problem-solving skills in the experimental group compared to the control group (p < 0.05). These findings suggest that integrating game-based applications within a STEM framework has a positive effect on students’ understanding of exponent concepts and their problem-solving abilities.

Abstract

Although mathematical communication is considered important, students still struggle to express mathematical ideas effectively. Therefore, this research is going to use a commognitive framework that provides a valuable lens for analyzing and enhancing students' mathematical communication skills. The purpose of this study is to describe students' cognition in solving linear programming problems. The researcher selected six students for interviews based on the consistency of their answers and then selected two students from the six students who had been interviewed. Commognitive analysis shows striking differences in mathematical thinking and communication between DAJ and ED subjects, who are students with high and low commognitive abilities, respectively. Students with high commognitive abilities tend to be more comprehensive and exploratory. In contrast, a student with low commognitive ability is relatively more limited and procedural. This implies that teachers cannot judge understanding only by whether students reach the correct answer. They must also attend to how students talk, write, and represent mathematics, since these discursive moves reveal whether their routines are genuinely conceptual or merely imitative. As a result, it is advised that future studies include a group discussion, better-developed question types, and more specified student criteria.

Abstract

Masalah sampah hingga saat ini masih menjadi masalah laten yang belum tertangani secara optimal, mulai dari pengumpulan hingga pengolahan. Sayangnya masalah ini tidak hanya dialami oleh daerah perkotaan, namun juga masalah di daerah pedesaaan. Di Desa Karangan Kecamatan Kepohbaru Kabupaten Bojonegoro, contohnya, masih banyak ditemukan sampah yang berserakan di jalan, selokan, bahkan di halaman rumah warga. Salah satu penyebabnya adalah kurangnya kesadaran masyarakat dan ketidaktersediaan tempat sampah. Gerakan Sapta Bamboo Karangan yang diinisiasi oleh KKN Universitas Islam Darul Ulum merupakan program pemberdayaan masyarakat dalam upaya menangani sampah di Desa Karangan. Tujuan program pemberdayaan masyarakat ini adalah memberikan kesadaran kepada masyarakat akan pentingnya mengelola sampah desa. Metode yang digunakan dalam program pemberdayaan ini adalah pendekatan preventif dan kuratif diantaranya ajakan hidup bersih melalui kerja bakti bersih desa, pemanfaatan bambu menjadi tempat sampah, dan pemanfaatan sampah plastik menjadi berbagai kerajinan. Hasil dari program ini terjalinnya kerjasama masyarakat Desa Karangan dalam membersihkan sampah sebagai bentuk kesadaran masyarakat akan pentingnya mengelola sampah desa dan tersedianya tempat sampah dari bahan bambu dan hasil kerajinan dari sampah plastik. Disarankan program pemberdayaan selanjutnya bisa melanjutkan program ini dan lebih intensif pada tahapan kuratif dalam hal pemanfaatan sampah.

Abstract

Penyelesaian masalah kolaboratif adalah suatu proses di mana siswa bekerja sama untuk memahami masalah, bertukar ide, mengembangkan strategi solusi, dan mengevaluasi solusi secara kolektif. Melalui proses ini, siswa membangun pemahaman matematika secara kolaboratif, sehingga mendukung pengembangan kemampuan pemecahan masalah matematika mereka. Penelitian ini bertujuan untuk mendeskripsikan kemampuan pemecahan masalah kolaboratif siswa dengan kemampuan matematika tinggi, sedang, dan rendah dalam menyelesaikan masalah matematika tentang barisan dan deret. Penelitian ini menggunakan pendekatan kualitatif dengan desain penelitian deskriptif. Partisipan penelitian terdiri dari enam siswa kelas sepuluh, yang dibagi menjadi tiga kelompok heterogen: kelompok kemampuan matematika tinggi-sedang, tinggi-rendah, dan sedang-rendah. Data dikumpulkan melalui tes kemampuan matematika, tes pemecahan masalah kolaboratif, observasi, dan wawancara. Hasil penelitian menunjukkan bahwa ketiga kelompok tersebut menunjukkan empat tahapan pemecahan masalah kolaboratif, yaitu eksplorasi dan pemahaman, representasi dan formulasi, perencanaan dan pelaksanaan, serta pemantauan dan refleksi. Perbedaan kemampuan matematika memengaruhi sifat kontribusi masing-masing anggota selama proses kolaboratif. Siswa dengan kemampuan matematika tinggi dan sedang cenderung berperan lebih aktif dalam memimpin diskusi dan mengembangkan strategi penyelesaian, sedangkan siswa dengan kemampuan matematika rendah terutama berkontribusi dengan menanggapi ide, melaksanakan tugas yang diberikan, dan merefleksikan proses pemecahan masalah. Meskipun demikian, semua kelompok mampu menyelesaikan masalah secara kolaboratif melalui komunikasi, kerja sama, dan pembagian peran.

Abstract

Literasi matematika merupakan keterampilan krusial yang memungkinkan siswa untuk merumuskan, menerapkan, dan menggunakan konsep-konsep matematika dalam berbagai konteks kehidupan sehari-hari. Namun, kemampuan literasi matematika siswa Indonesia terkait topik ketidakpastian dan data masih tergolong rendah, sehingga analisis kesalahan perlu dilakukan untuk mengidentifikasi jenis-jenis kesalahan yang mereka buat. Penelitian ini bertujuan untuk mendeskripsikan jenis-jenis kesalahan yang dilakukan oleh siswa SMP saat menyelesaikan soal-soal setara PISA mengenai ketidakpastian dan data, ditinjau dari perspektif kecerdasan majemuk. Penelitian ini menggunakan pendekatan kualitatif deskriptif dengan tiga siswa kelas IX SMP Negeri 1 Sooko sebagai subjek, yang masing-masing mewakili kecerdasan visual-spasial, verbal-linguistik, dan logis-matematis. Data dikumpulkan melalui kuesioner kecerdasan majemuk, tes kemampuan matematika, soal PISA-like, dan wawancara. Analisis data dilakukan melalui identifikasi kecerdasan majemuk, analisis hasil tes kemampuan matematika, analisis kesalahan berdasarkan teori Nolting, serta analisis hasil wawancara. Hasil penelitian menunjukkan bahwa siswa dengan kecerdasan visual-spasial melakukan misread-directions errors, careless errors, concept errors, application errors, and test-taking errors. Siswa dengan kecerdasan verbal-linguistik melakukan misread-directions errors, concept errors, application errors, and test-taking errors. Sementara itu, siswa dengan kecerdasan logis-matematis melakukan misread-directions errors, application errors, and test-taking errors. Kesalahan-kesalahan tersebut dipengaruhi oleh penulisan informasi yang tidak lengkap, kesalahpahaman dan penerapan konsep yang keliru, kurangnya ketelitian, serta keterbatasan waktu. Penelitian ini menyimpulkan bahwa setiap kategori kecerdasan majemuk menunjukkan kecenderungan terhadap jenis kesalahan yang berbeda.

Abstract

Open-ended problems require students to think deeply and use various methods and answers, but many students are not accustomed to them, which leads to their not being able to solve them correctly. Students’ errors are related to field dependent and field independent cognitive styles, which influence differences in understanding and analytical abilities, highlighting the necessity of suitable scaffolding catered to students' requirements. This study aims to describe the provision of scaffolding for students’ errors in solving open-ended problems based on field dependent and field independent cognitive styles. This study used a descriptive qualitative approach. The research subjects consisted of one field dependent student and one field independent student who made the most frequent and varied errors in solving open-ended problems. The selection of research subjects also considered equivalence in mathematical ability and the same gender. The instruments used in this study were the group embedded figures test, a mathematics ability test, an open-ended problem test, an interview and scaffolding guidelines. The research data were analyzed through three stages: data condensation, data display, and conclusion drawing. The results showed that student with a field dependent cognitive style made errors in comprehension, transformation, process skills, and encoding. The scaffolding provided included reviewing, explaining, restructuring, and developing conceptual thinking. Meanwhile, student with a field independent cognitive style made errors in comprehension, transformation, and process skills. The scaffolding provided included reviewing and restructuring. The results of the study showed that scaffolding was able to reduce errors made by field dependent student and address errors made by field independent student in solving open-ended problems.

Abstract

Abductive reasoning is the process of formulating conjectures to explain surprising observations. Although these conjectures are not necessarily true, this type of reasoning is highly helpful in problem-solving for determining the best solution strategy. This study aims to investigate the differences in abductive reasoning across different cognitive styles. This research method uses a qualitative descriptive approach. The participants in this study were 32 students. Two of them were then selected for in-depth interviews representing types of abductive reasoning. Data collection and analysis were carried out on students' work results and semi-structured interviews. Polya's problem-solving theory was used to analyze students' thinking processes using abductive reasoning. The analysis was conducted on all problem-solving steps, namely understanding the problem, devising a plan, carrying out the plan, and looking back. Students with a field independent cognitive style were able to recognize and understand the problem quickly and directly determine the appropriate formula. In contrast, students with a field dependent cognitive style tended to understand the problem globally, requiring more time to complete the questions.

Abstract

In the 2015 TIMSS, Indonesian students scored 397, ranking 44th out of 49 countries. This data suggests that Indonesian students consistently lack critical thinking skills in mathematics. The purpose of this study was to investigate the role of scaffolding within a Problem-Based Learning (PBL) framework in enhancing the critical thinking skills of junior high school students. This study employed a quantitative approach with a quasi-experimental design, which involved one experimental group. For this study, a random sample of 27 eighth-grade students was selected. Data were collected using a critical thinking test evaluated through an essay test created based on criteria established by Facione. Data analysis was carried out descriptively and inferentially. The data normality test, using the Shapiro Wilk test, showed that most of the data were not normally distributed; therefore, the inferential analysis was continued with the nonparametric Wilcoxon Signed Ranks Test. Data processing was conducted using SPSS software version 30.0. The primary instrument employed in this study was a critical thinking test in the form of an essay, developed based on Facione's theoretical framework.  The findings indicate that the integration of scaffolding into Problem-Based Learning (PBL) significantly enhances students’ critical thinking skills. Scaffolding optimizes the effectiveness of PBL, whereas PBL without scaffolding tends to be less effective in developing students’ potential evenly. These results suggest that mathematics teachers should implement scaffolding in a systematic and gradual manner to foster more reflective, structured, and higher-order thinking–oriented learning.

Abstract

Proportional reasoning is the foundation of mathematical abilities, including algebra, geometry, and statistics, and is influenced by students' mathematical dispositions. The transition from additive to multiplicative reasoning plays a crucial role in problem-solving. This study explores junior high school students' strategies in understanding geometric similarity through a qualitative case study involving three students in Surabaya selected through purposive sampling based on high, medium, and low mathematical dispositions This study uses a qualitative approach with a case study method.  The subjects of the study consisted of three eighth-grade students purposively selected to represent high, medium, and low mathematical disposition, allowing an in-depth examination of how different dispositions influence proportional reasoning. The instruments used were similarity problem worksheets and semi-structured interview guidelines. Data were collected through student answers and interviews, then analysed through data reduction, data presentation, and drawing conclusions. The results showed differences in proportional reasoning strategies according to mathematical disposition: S1 at level 3 (Formal Reasoning), S2 at level 2 (Quantitative Reasoning), and S3 at level 0 (Non-Proportional Reasoning). Proportional reasoning develops when quantity coordination and multiplicative strategies are used in an integrated manner, in line with each student's mathematical disposition. Student with high disposition consistently use ratio-based multiplicative strategies, student with medium disposition use multiplicative strategies, while student with low disposition tend to use additive rules or random approaches. These findings are exploratory and can serve as a basis for studying misconceptions and developing proportional learning.

Abstract

Mathematics learning in junior high schools often faces challenges in developing algebraic problem-solving skills because the concepts are abstract and symbolic. This study investigates the impact of GeoGebra on junior high school students' algebraic problem-solving skills, analyzed through Polya's problem-solving stages. The research method used is qualitative with a case study approach on two eighth-grade students. Data were collected through observations, interviews, and analysis of student work documents, both before and after using GeoGebra. The results showed that with conventional methods, students could solve the problem correctly, but only part of the Polya stages were achieved and the rest were not written in full. Meanwhile, the use of GeoGebra allows students to display all stages of Polya in a more systematic and structured manner, from understanding the problem to re-examining the solution. GeoGebra also provides visualization in the form of images, which increases student engagement and understanding of algebraic concepts. Thus, GeoGebra effectively improved junior high school students' problem-solving skills.
