The main objective of this study is to identify and explain students’ errors in solving PISA questions on Space and Shape content using Newman’s Error Analysis. The errors analyzed include five categories: reading errors, comprehension errors, transformation errors, process skill errors, and encoding errors. This study employs a descriptive qualitative approach with data collected through tests and interviews. The research subjects are ninth-grade students at SMP Negeri 7 Muaro Jambi. The results show that students frequently made errors in the stages of understanding the questions, modelling the questions into mathematical forms, and process skills. These errors were by weaknesses in processing information, limited mathematical skills in real-life contexts, and a lack of experience in practicing PISA questions. These findings highlight the importance of familiarizing students with contextual problems as an effort to minimize errors in solving PISA questions.

The issue of climate change is a global problem that is very strategic to be overcome, because it has an impact on the environment. Low ability to understand and interpret climate change data presented statistically is associated with low statistical literacy skills. Statistical literacy is the critical ability to access, understand, interpret, and evaluate statistical information or messages in various contexts. This underlies researchers to design learning trajectories using the context of climate change to train the statistical literacy skills of prospective teacher students. The method used is the design of research type validations studies with the subject of prospective teacher students. This research produced HLT which is able to facilitate statistical literacy skills and successfully identify the level of statistical literacy ability of students who are at low and middle stages.

This study aimed to analyze students’ answers in solving number pattern problems in terms of analogical reasoning ability. Six seventh-grade students with varying academic levels participated in the study. Data were collected through written tests and semi-structured interviews, then analyzed using the analogical reasoning framework, which includes four indicators: encoding, inferring, mapping, and applying. The results showed that the total scores of the six participants ranged from 18 to 30. Student 1 obtained the lowest score (18), indicating weaknesses particularly in applying pattern rules to determine the required terms correctly. In contrast, Students 3, 4, and 5 achieved the maximum score of 30, demonstrating consistency in recognizing pattern rules, mapping structural similarities, and applying their reasoning accurately across tasks. The average total score was 27.5, suggesting that most students demonstrated relatively strong analogical reasoning skills, although some individuals still experienced difficulty in the applying stage, which demands higher precision and conceptual understanding. The study contributes to understanding how analogical reasoning influences students’ mathematical problem-solving and offers pedagogical insights for enhancing instruction of non-routine tasks through reasoning-based learning strategies.

Mathematics is a fundamental subject for junior high school students, yet numeracy achievement in Indonesia, including in Simbur Naik Village, remains low. This community service activity aimed to improve students’ conceptual understanding and learning motivation through the implementation of the MathVerse application, which integrates Augmented Reality and Artificial Intelligence. The program involved 53 students and 6 mathematics teachers, carried out in three sessions consisting of socialization, training, and classroom implementation. The results indicated a significant improvement in cognitive achievement. The average test score increased from 49.15 to 70.67, while mastery rose from 33% to 70%. In terms of motivation, there was an increase in the indicators of effort and perceived relevance of mathematics, although interest and self-efficacy slightly declined. Student responses were highly positive, with the highest scores on the indicators of understanding and learning (82.94%) and application navigation (93.52%). Teachers also expressed consistently positive responses, with the highest rating on interest and adoption (90.63%). Documentation highlighted students’ enthusiasm in using AR and AI features, as well as teachers’ active role in facilitating the process. This activity demonstrates that MathVerse not only significantly enhances students’ conceptual understanding of mathematics but also fosters learning interest and strengthens teachers’ roles in integrating educational technology. The novelty of this program lies in the direct application of AR- and AI-based learning tools in rural schools, which are rarely reached by digital innovations. Therefore, this activity provides tangible benefits for the local education community and contributes theoretically to the effectiveness of multimedia learning and technology acceptance in mathematics education.

Statistical literacy is a critical 21st-century competency, as students increasingly encounter data-driven information in their everyday lives. However, international assessments such as PISA consistently show that Indonesian students struggle to interpret and reason with data. This study aims to investigate junior high school (JHS) students’ statistical literacy in solving PISA-based problems related to uncertainty and data, while also linking the results to Sustainable Development Goal (SDG) 4: Quality Education. A descriptive qualitative approach was employed involving 40 ninth-grade students from JHS Negeri 6 Kota Jambi, selected through purposive sampling to represent high, medium, and low academic ability groups. Data were collected through a validated PISA 2012 item focusing on uncertainty and data, along with semi-structured interviews designed to explore students’ statistical-literacy strategies. Data analysis followed an interactive model consisting of data reduction, data display, and conclusion drawing, guided by Schield’s (2011) statistical-literacy indicators. The findings indicate that only 17.5% of students demonstrated a high level of statistical literacy, while most were categorized as medium (37.5%) or low (45%). Further analysis revealed persistent difficulties in identifying trends, calculating averages, and drawing valid conclusions. These findings underscore the need for contextual, PISA-based learning tasks that foster statistical reasoning and strengthen students’ fundamental literacy skills as a foundation for achieving quality education.

This study examines the creative thinking of Grade 12 students in solving open-ended statistical problems. The research addresses the problem of limited understanding of how students with different mathematical ability levels demonstrate creative thinking when working with open-ended statistical tasks, and aims to describe the fluency, flexibility, originality, and elaboration reflected in their solutions. Three students representing high, medium, and low achievement levels were selected through purposive sampling to capture varied mathematical abilities. Data were collected through written tests and interviews, and analyzed using indicators of fluency, flexibility, originality, and elaboration. An exploratory, qualitative approach was employed to gain in-depth insights into students’ reasoning processes. Results show that the high-achieving student generated two valid datasets (mean = 25, median = 23, mode = 20), the medium-achieving student produced one nearly accurate dataset (mean = 24.9), and the low-achieving student produced a dataset with a mean of 23.5. For the second problem, all students obtained b = 12, but only the high-achieving student justified why it is the minimum. In the third problem, all calculated the average yield as 1.225 tons, yet only the high-achieving student provided a contextual interpretation. These findings indicate that open-ended tasks reveal clear differences in students’ creative thinking. The results suggest that incorporating open-ended problems into statistics lessons can enhance students’ creative mathematical reasoning and support the development of higher-order thinking.

External representation is essential in mathematics learning because it enables students to express and operationalize abstract ideas. However, many junior high school students still struggle to coordinate visual, mathematical, and verbal representations when solving solid geometry problems. This study aims to explore how students demonstrate external representations in solving solid geometry tasks by analyzing their pretest responses. A descriptive qualitative method was used involving nine students who completed a pretest, from which three were purposively selected to represent high, medium, and low levels of external representation ability. Data were collected using a test instrument based on indicators of visual, mathematical, and verbal representations. The results show that high-performing students can consistently produce accurate visualizations, mathematical expressions, and written explanations, while medium-performing students demonstrate inconsistent and partial representations. Low-performing students encounter major difficulties in generating meaningful representations. The findings suggest that teachers should strengthen geometry instruction by promoting the balanced use of visual, mathematical, and verbal representations to support students’ conceptual understanding.
