Abstract

This research aims to develop a learning media based on Tailwind CSS and GeoGebra in the topic of Transformation Geometry for ninth-grade students at MTsN 2 Mataram. The background of this study is students’ difficulties in understanding transformation geometry concepts due to their abstract nature and the limitations of conventional learning media, which tend to be less interactive. The method used in this study was Research and Development (R&D) with ADDIE (Analysis, Design, Development, Implementation, Evaluation) as the development model. The research sample consisted of ninth-grade E class students of MTsN 2 Mataram. The developed learning media was evaluated for its feasibility by media experts and tested with students. The validation results showed that the developed learning media met the feasible criteria with a feasibility percentage of 74,6%. The practicality test through student questionnaires also indicated a very practical category with a practicality percentage of 93,65%. Therefore, the learning media based on Tailwind CSS and GeoGebra is considered feasible and practical to be used as a learning aid in teaching transformation geometry at schools.

Abstract

This study aims to describe students' concept images on sequences and series in differentiated learning and to examine the concept image gap between students, teachers, and mathematicians. This study used a qualitative approach with a didactic design and a hermeneutic phenomenology method. The research subjects included students, teachers, and mathematicians, who were selected purposively. Data were collected through learning observations, questionnaires, and in-depth interviews, and then analyzed using data reduction, data presentation, and conclusion-drawing techniques. The results showed that students' conceptual images of sequences and series were dominated by intuitive, visual, and procedural understandings. Students were able to recognize real-world patterns and contexts, but tended to rely on repeated addition or multiplication rather than using formal definitions and symbolic formulas. In geometric sequences and series, a concept image conflict was found due to students' difficulty in understanding exponential growth patterns. Although differentiated learning provides space for diverse student learning styles, the results show that this approach does not fully guarantee the formation of a complete formal conceptual understanding. Therefore, strengthening conceptual scaffolding is needed so that students' concept images are more aligned with the correct concept definition. Penelitian ini bertujuan untuk mendeskripsikan concept image siswa pada materi barisan dan deret dalam pembelajaran berdiferensiasi serta mengkaji kesenjangan concept image antara siswa, guru, dan matematikawan. Penelitian ini menggunakan pendekatan kualitatif dengan desain didaktis dan metode fenomenologi hermeneutik. Subjek penelitian meliputi siswa, guru, dan matematikawan, yang dipilih secara purposif. Pengumpulan data dilakukan melalui observasi pembelajaran, kuesioner, serta wawancara mendalam, kemudian dianalisis menggunakan teknik reduksi data, penyajian data, dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa concept image siswa pada materi barisan dan deret didominasi oleh pemahaman intuitif, visual, dan prosedural. Siswa mampu mengenali pola dan konteks nyata, namun cenderung mengandalkan penjumlahan atau perkalian berulang dibandingkan penggunaan definisi formal dan rumus simbolik. Pada barisan dan deret geometri, ditemukan conflict concept image akibat kesulitan siswa dalam memahami pola pertumbuhan eksponensial. Meskipun pembelajaran berdiferensiasi memberikan ruang bagi keberagaman cara belajar siswa, hasil penelitian menunjukkan bahwa pendekatan ini belum sepenuhnya menjamin terbentuknya pemahaman konseptual formal yang utuh. Oleh karena itu, diperlukan penguatan scaffolding konseptual agar concept image siswa lebih selaras dengan concept definition yang benar.

Abstract

Background: Type 2 diabetes mellitus (T2DM) is typically in line with dyslipidaemia, which substantially increases cardiovascular risk. Glycated haemoglobin (HbA1c) reflects long-term glycaemic control and has been proposed as a potential surrogate marker for lipid abnormalities. However, evidence regarding the correlation between HbA1c and lipid profile components remains inconsistent, particularly in Southeast Asian populations. This study aimed to evaluate the correlation between HbA1c levels and lipid profile parameters among patients with T2Dm treated at a tertiary referral hospital in Indonesia. Methods: A cross-sectional analytic study was conducted using medical record data from 68 patients with T2DM. HbA1c levels and lipid profile parameters–including total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and triglycerides–were analysed. Data normality was assessed using the Kolmogorov–Smirnov test. Spearman’s rank correlation test was applied to determine the correlation between HbA1c and lipid profile components. Results: The median HbA1c level was 8.70% (range: 4.90–14.70%), indicating suboptimal glycaemic control. Median lipid profile values were 203.50 mg/dL for total cholesterol, 55.50 mg/dL for HDL cholesterol, 115.00 mg/dL for LDL cholesterol, and 138.50 mg/dL for triglycerides. Correlation analysis revealed no statistically significant association between HbA1c levels and any lipid profile component. Conclusion: HbA1c levels were not significantly correlated with lipid profile parameters in patients with T2DM. These findings suggest that glycaemic control alone may not adequately reflect lipid-related cardiovascular risk, underscoring the need for comprehensive cardiometabolic assessment in patients with T2DM.

Abstract

This study aims to analyze mathematical literacy skills in solving PISA mathematics questions based on the level of mathematical literacy skills among students at SMPN 13 Mataram in the 2024/2025 academic year. This is a descriptive qualitative study involving 52 students from classes IX A and IX B, with 8 students selected as subjects. The research instruments used were a mathematics literacy test adapted from PISA and interview guidelines. Data were analyzed based on mathematics literacy process indicators (formulate, employ, interpret). The results showed that out of the 6 levels of mathematical literacy, no students reached levels 5 and 6. At level 1, students could formulate explicit information and solve problems using simple algorithms, at level 2, they could identify implicit information and select basic strategies to solve problems; at level 3, they could process complex explicit information containing distractors and develop sequential strategies for decision-making, while Level 4 can formulate explicit information in everyday contexts and apply strategies to complex concrete situations. Students at Levels 1-4 also have the ability to interpret and draw conclusions based on the context of the problem.

Abstract

The perception of mathematics as a difficult subject often leads students to make errors. Errors made by students when solving story problems need to be analyzed to determine the cause. Mathematics anxiety is one of the causes of students making errors. This study aims to describe the errors made by students of SMPN 6 Mataram in answering story problems based on Newman's theory in terms of students' level of mathematics anxiety. The type of research used is qualitative. The research instruments used were anxiety level questionnaires, story problem tests, and interview guidelines. The selection of subject in class IX F used a purposive sample with the criteria: (1) students who had learned the system of linear equations in two variables (SPLDV), (2) students who had completed the mathematics anxiety questionnaire, (3) students from one class representing high, moderate, and low levels of mathematics anxiety. The results show that mathematics anxiety influences the types of errors students make in solving SPLDV word problems. Students with high anxiety made errors in comprehension, transformation, process skills, and conclusion stages; those with moderate anxiety in comprehension, process skills, and conclusion; while students with low anxiety mainly erred at the conclusion stage.
