description: The problems experienced by junior high school students in solving story problems involving integer addition using number lines include difficulty understanding the meaning of negative signs, transforming problem information into mathematical models, performing calculations correctly, and writing complete final answers in contextThis study aims to analyze the errors made by seventh-grade students at SMPK St. Maria Assumpta Kupang in solving story problems on integer addition using number lines based on Newman's error analysis stages. This study is qualitative in nature and uses a descriptive method. The research subjects consisted of three seventh-grade students from class VII B who were selected using purposive sampling based on their mathematical ability in solving story problems. The research instruments were story problem tests, interview guidelines, and documentation. Data analysis was carried out through data reduction, data presentation, and conclusion drawing, while data validity was obtained through triangulation techniques. The results showed that subjects with high ability (SKT) were able to read, understand, transform, and calculate correctly using number lines, but still made mistakes in the encoding stage because they did not write down the answer units. Subjects with moderate ability (SKS) made mistakes in reading negative symbols, misunderstood the meaning of the questions, incorrectly transformed information, and made mistakes in the calculation process, resulting in incorrect answers. Subjects with low ability (SKR) made the most errors, ranging from reading, understanding, transformation, processing, to writing the final answer, because they wrote down the results directly without following the correct procedure.

KAJIAN KONSEPTUAL TENTANG LIMIT FUNGSI SEBAGAI FONDASI PEMBELAJARAN KALKULUS
type: item
description: This study aims to examine the basic concept of function limits in calculus and analyze their vital role as the main foundation in learning calculus. The research method employed is a literature review, analyzing various sources such as textbooks and scientific journal articles related to limit concepts, student misconceptions, and relevant pedagogical strategies. Data analysis was conducted qualitatively and descriptively to synthesize the relationship between the concept of limits, derivatives, and integrals. The results indicate that the limit is a fundamental concept that explains functional behavior and serves as the formal basis for defining derivatives as rates of change and integrals as area accumulation (Riemann sums). The study concludes that a strong conceptual understanding of limits is essential to avoid the dominance of mechanistic procedures and to help students master advanced calculus concepts systematically. It is suggested that calculus instruction should emphasize visual representation and mathematical interpretation, although this study is limited to a literature approach without empirical field data.

KEMAMPUAN BERPIKIR KRITIS MAHASISWA DALAM MENYELESAIKAN MASALAH STATISTIKA MATEMATIKA BERDASARKAN TIPE KEPRIBADIAN EKSTROVERT DAN INTROVERT
type: item
description: Critical thinking ability is an essential component in solving mathematical problems, particularly in mathematical statistics topics such as probability. This study aims to analyze students' critical thinking abilities in solving probability problems in terms of extrovert and introvert personality types. The study employs a qualitative approach using a case study method. The research subjects consisted of two students with extrovert personality types and two students with introvert personality types, selected through the Myers-Briggs Type Indicator (MBTI) test. The research instruments included the MBTI personality test, a written test on probability, an interview guide, and an observation sheet. The data were analyzed through data reduction, data display, and conclusion drawing in an interactive manner. The results of the study indicate that extroverted students tend to be able to identify basic information from the problem but show weaknesses in evaluation, inference, explanation, and self-regulation. On the other hand, introverted students demonstrate a more systematic, reflective, and logical thinking pattern, although they sometimes lack verbal explanations for their chosen strategies. These findings suggest that personality type influences the quality of students' critical thinking abilities in solving probability problems. Therefore, personality-based learning strategies need to be developed to optimize students' critical thinking skills in mathematical statistics learning.

IDENTIFIKASI KEMAMPUAN BERPIKIR KREATIF SISWA PADA PENYELESAIAN MASALAH GEOMETRI
type: item
description: This study aims to measure the creative thinking ability of eighth-grade students in geometry material at Muhammadiyah Sempor Middle School. This type of research is descriptive qualitative. The technique for selecting subjects uses a purposive method with two selected subjects. The data collection techniques employed are observation, tests , interviews, and field notes methods. The steps in data analysis include data reduction, data presentation, and drawing conclusions/verification. Based on the findings of the research conducted on eighth-grade students at Muhammadiyah Sempor Middle School, it was concluded that the creative thinking ability demonstrated by students in solving geometry problems is still at a fairly creative level. This is because students are limited in answering questions in two ways ; they have not been patient in compiling answers in detail (writing knowns , asked questions, steps/stages, and final conclusions), leading them to focus immediately on working on mathematical models. Furthermore, students have not been able to solve problems in their own unique and unconventional ways, so they continue to use the methods provided by the teacher. Students also encounter obstacles, such as being inconsistent in writing units and mathematical symbols in the form of roots. Additionally, students demonstrate inaccuracy in writing the names of the angles of the triangle

MODEL PEMBELAJARAN GURU YANG KURANG VARIATIF DAN DAMPAKNYA TERHADAP PEMBELAJARAN MATEMATIKA
type: item
description: The learning models used by teachers play an important role in building students’ concentration, motivation, and learning engagement. However, various studies over the past ten years indicate that teachers still tend to use monotonous teaching models such as lectures, repetitive exercises, and assignment-based learning without variation. This condition has an impact on the decline of students’ learning concentration, especially in mathematics, which requires strong analytical skills and high levels of focus. This Systematic Literature Review (SLR) aims to map the development of research regarding the relationship between the lack of variation in teachers’ teaching models and students’ learning concentration at the elementary, junior high, and senior high school levels. Using sources from Google Scholar and SINTA (2015–2025), this SLR finds that less varied teaching models contribute to low learning focus, increased boredom, reduced attention to teacher explanations, and weakened understanding of mathematical concepts. On the other hand, the application of cooperative learning models, problem-based learning, technology-based learning models, and interactive learning models has been proven to improve students’ concentration and participation. The results of this study emphasize the importance for teachers to choose learning models that are relevant, adaptive, and varied in order to enhance students’ learning concentration.

STUDI LITERATUR: KEMAMPUAN PEMECAHAN MASALAH MATEMATIS SISWA DALAM PEMBELAJARAN MATEMATIKA
type: item
description: This study aims to examine mathematics education research on mathematical problem-solving skills published in SINTA-indexed mathematics education journals from 2022 to 2023. Methodologically, this study uses a qualitative content analysis approach. The analysis was conducted on several main aspects that are the focus of the study. First, based on the research approach, it shows a tendency towards a descriptive qualitative approach. The dominance of the descriptive qualitative approach in this study indicates a strong tendency in mathematics education studies that focus on revealing and measuring problem-solving indicators in depth and context. Second, based on the distribution of research subjects in this study, it shows an uneven trend, where Junior High School students are the most dominant group studied compared to other levels of education. This phenomenon reflects the crucial existence of research that focuses on the phase of cognitive development of students at the SMP level, which theoretically represents a transitional stage from concrete to abstract thinking. Third, based on the distribution of topics, it provides an illustration that studies on mathematical problem-solving skills have been conducted in various material contexts, but there are still opportunities to expand the scope of research, especially on materials that have not been widely explored.

PERSEPSI MAHASISWA TERHADAP TINGKAT KESULITAN MATA KULIAH KALKULUS: KAJIAN LITERATUR TENTANG FAKTOR PENYEBAB DAN STRATEGI PEMBELAJARAN
type: item
description: Calculus is a fundamental subject that plays an important role in various scientific disciplines, yet it is often perceived as difficult by university students. This study aims to examine students’ perceptions of the difficulty of calculus, identify the contributing factors, and explore effective learning strategies to address these challenges. The research employs a library research method by analyzing relevant scientific literature. The results indicate that calculus is still considered difficult by most students due to internal factors such as low prior knowledge, weak conceptual understanding, low motivation, and negative attitudes, as well as external factors including the abstract nature of the material and less varied teaching strategies. Students’ difficulties are reflected in errors in understanding concepts, recalling formulas, and performing calculations. To overcome these issues, student-centered learning strategies are required, including strengthening basic concepts, intensive practice, the use of interactive media, project-based learning, and group discussions. With appropriate strategies and a supportive learning environment, negative perceptions of calculus can be reduced, leading to improved student understanding

AN ANALYSIS OF SINGAPOREAN AND INDONESIAN MATHEMATICS CURRICULA AND THEIR IMPLICATIONS BASED ON BLOOM’S TAXONOMY
type: item
description: This research is motivated by the discrepancy in numeracy literacy achievements between Singapore and Indonesia in PISA studies. The objective is to analyze the comparative distribution of cognitive levels in the mathematics curriculum of both countries based on Bloom's Taxonomy and its implications for learning quality. This research employs a qualitative method with content analysis of the Indonesian Kurikulum Merdeka (Phase D) and the Singaporean Mathematics Syllabus (Secondary School). The results show that the Indonesian curriculum is dominated by the C3 level (Applying) at 40%, emphasizing procedural skills. In contrast, the Singaporean curriculum is dominated by the C5 level (Evaluating) at 30%, requiring mathematical reasoning and justification. The conclusion indicates that Singapore's curriculum is stronger in integrating Higher Order Thinking Skills (HOTS). Consequently, Indonesian policy developers should redesign Learning Outcomes by increasing the proportion of C4 and C5 levels to foster students' critical thinking skills.
