Abstract

The average mathematics score of eighth-grade students at MTsN Samarinda is still low (62.80). Students have difficulty solving modified problems, lack attention to detail, and show anxiety such as hesitation, lack of confidence, and fear of answering. This study aims to describe students' mathematical problem-solving abilities based on their level of mathematical anxiety in linear equation material. The research used a qualitative descriptive approach with eighth-grade students at MTsN Samarinda as the subjects. The data were analyzed through data reduction, data presentation, and conclusion drawing. The results show that students with high anxiety have varying abilities: some experience difficulties in all stages of problem solving, but some are able to meet three indicators in some questions and only one indicator in other questions. They show somatic, cognitive, and attitudinal symptoms. Students with moderate anxiety are only able to meet three problem-solving indicators, with dominant symptoms in cognition and attitude. Meanwhile, students with low anxiety also showed varying abilities: some were able to meet all indicators on some questions, but others did not complete the final stage (rechecking) due to overconfidence and time constraints. The anxiety symptoms that appeared at low levels were mild and did not interfere with the problem-solving process.

Abstract

Textbooks play an important role in shaping students' understanding of statistical concepts. However, when conceptual representations emphasize procedural aspects rather than conceptual understanding, they may contribute to misconceptions. This study aims to analyze how the concept of the homogeneity of variance test is represented in educational statistics textbooks and to identify the potential misconceptions arising from these representations. The study employed a descriptive qualitative approach using document analysis. The data consisted of ten educational statistics and statistics-for-educational-research textbooks that are widely used in teacher education programs in Indonesia. Data were collected through document review and analyzed using qualitative content analysis, focusing on definitional, procedural, and conceptual representations, as well as potential misconceptions. The findings indicate that all textbooks present the F-test procedure by dividing the larger variance by the smaller variance. However, only a few textbooks explain the underlying concept of the F distribution, the rationale for placing the larger variance in the numerator, and the relationship between the F distribution and statistical decision-making. The dominance of procedural representations may lead students to the misconception that the larger variance must always be placed in the numerator and that the F statistic can never be less than one. These findings suggest that the current representation of the homogeneity of variance test in educational statistics textbooks does not adequately support the development of students' conceptual understanding. Therefore, a more balanced presentation integrating both procedural and conceptual aspects is needed to minimize potential misconceptions in statistics education.

Abstract

Algebraic generalization problems pose a significant challenge, requiring teachers to recognize influencing factors like Field Independent (FI) and Field Dependent (FD) cognitive styles. The purpose of this study was to apply binary logistic regression to map students' cognitive styles, either FI or FD, based on their error patterns when solving algebraic thinking generalization problems. These errors were classified using the five categories of Newman’s Theory: Reading (R), Comprehension (C), Transformation (T), Process Skill (S), and Encoding (E). This exploratory correlational study involved 40 tenth-grade students from SMA IT Granada Samarinda. Cognitive style (the dependent variable) was measured using the GEFT, while the Newman error categories (the independent variables) were identified from a generalization instrument adopted from TIMSS (2003–2019). The results found that 23 out of 40 students made mistakes, consisting of 9 FI students and 31 FD students. The binary logistic regression results showed that the Process Skill (S) error was the strongest predictor for the FI style, with an odds ratio of 18.025. This means that students who make an S error are 18 times more likely to be classified as FI. This finding leads to the conclusion that FI students struggle with the details of procedural implementation, despite possessing a strong strategic understanding. Binary logistic regression proved effective as a diagnostic tool to support more personalized mathematics learning strategies.

AbstrakProgramme for International Student Assessment (PISA) diprakarsai oleh Organization for Economic Cooperation and Development (OECD) menginisisasi melakukan evaluasi sistem pendidikan suatu negara di seluruh dunia. PISA melakukan tes literasi membaca, literasi matematika dan literasi sains siswa berusia 15 tahun secara acak di suatu negara setiap tiga tahun sekali. Hasil studi PISA untuk literasi matematika, siswa Indonesia masih jauh dari yang diharapkan. Agar siswa memiliki kemampuan literasi matematika yang bisa bersaing secara global, maka standar kompetensi literasi guru matematika masih perlu ditingkatkan kualitasnya, khususnya terkait dengan penyusunan soal literasi matematika yang sesuai model PISA dengan konteks setempat. Kegiatan ini memberikan pelatihan keterampilan dalam mendesain soal literasi matematika model PISA untuk guru matematika di kabupaten Kutai Kartanegara dengan menggunakan pendekatan etnomatematika (konteks sosial budaya masyarakat Kutai). Tujuan kegiatan pelatihan ini adalah agar mitra nantinya mampu mendesain soal-soal literasi matematika model PISA dalam pembelajaran di kelas dengan pendekatan etnomatematika masyarakat Kutai yang mudah dipahami dan familiar bagi siswa. Metode kegiatan yang digunakan dalam pelatihan ini adalah: (1) Metode ceramah digunakan untuk memberikan pemahaman mengenai soal matematika model PISA, literasi matematika, dan soal-soal matematika menggunakan konteks sosial budaya Kutai (etnomatematika); (2) Metode demonstrasi diberikan untuk melatih dan mendampingi guru mendesain soal literasi matematika model PISA menggunakan konteks sosial budaya Kutai (etnomatematika) dan (3) Metode praktik, peserta mempraktikkan semua materi yang sudah didapatkan sebelumnya.  Hasil kegiatan yang telah dilaksanakan guru matematika mampu mendesain soal-soal literasi matematika model PISA menggunakan konteks sosial budaya masyarakat Kutai (etnomatematika). AbstractThe Program for International Student Assessment (PISA) initiated by the Organization for Economic Cooperation and Development (OECD) has initiated an evaluation of the education systems of a country around the world. PISA tests reading literacy, mathematical literacy and scientific literacy of 15-year-old students at random in some country every three years. The PISA results for mathematical literacy, students in Indonesia are still far from what is expected. In order for students to have mathematical literacy skills that can compete globally, the literacy competency standards of mathematics teachers in Indonesia still need to be improved in quality, especially related to making mathematical literacy problems according to the PISA model with the local context. The purpose of this activity is so that partners will be able to design PISA model mathematical literacy problems in classroom learning with an ethnomathematical approach of Kutai community that is easy to understand and familiar for students.

Abstract

The Free Nutritious Meal Program (MBG) and fruit-processing business activities around the madrasah environment generate a daily volume of fruit peel waste that has not yet been managed. This activity aims to initiate the processing of fruit peel waste into eco-enzyme at MAN 1 Samarinda as a pilot for independent organic waste management. A total of 3,000 grams of fruit peel waste was collected on 2 September 2026 from a fruit juice processing business near the activity location, consisting of orange and watermelon peels. Of this amount, 3,000 grams were processed into 1 fermentation container with a sugar : organic waste : water ratio of 1 : 3 : 10. Fermentation began on 2 September 2026 and was observed at the beginning and end of the observation period, namely day 0 and day 14, through organoleptic parameters including color, aroma, and gas formation. Observation results on day 14 compared to day 0 showed a change in solution color from clear pale yellow to light brown/murky brown.
