This study is qualitative descriptive research that aims to describe eighth-grade students’ numeracy skills in solving a PISA 2022 quantity content problem. This focus is important because PISA-type tasks require reasoning, quantitative interpretation, and decision-making skills that are essential for students’ mathematical literacy in real-life situations. Thirty-two eighth-grade students of a junior high school in Jambi, Indonesia, participated in this study. Data were collected through a written test adapted from the PISA 2022 released items and follow-up interviews with selected students. The results showed that most students demonstrated low numeracy performance, particularly in interpreting information, performing multi-step calculations, and drawing correct conclusions. Only a small number of students were able to meet the expected indicators of numeracy skills. These findings indicate that students have not yet fully met the cognitive demands of PISA quantity tasks. The results highlight the need for instruction that provides more opportunities for students to practice contextual quantitative reasoning. For classroom practice, teachers are encouraged to incorporate multi-step contextual tasks that gradually strengthen students’ interpretation, strategy selection, and reasoning abilities. The findings also serve as a basis for further research on developing PISA-type jumping tasks adapted to relevant local contexts to support students’ numeracy skills.

Indonesian students’ relatively low performance in PISA has been closely linked to their difficulties in applying mathematical knowledge to real-world contexts, which often led to errors. The main objective of this study was to explore the types of mistakes students made when solving PISA-type questions within the content area of uncertainty and data. This research was qualitative descriptive in nature. The research subjects consisted of five ninth-grade students from a junior high school in Jambi Province, selected based on teacher recommendations. Data were collected through tests and interviews. The results of the study showed that students frequently made mistakes at the stage of writing the final answer, primarily due to difficulties in interpreting the given information and focusing too heavily on calculation procedures while overlooking what the problem was actually asking. These findings provide a basis for further research on analyzing students’ mathematical literacy skills in solving PISA questions, particularly within the domain of uncertainty and data.

This study aims to analyze students’ mathematical literacy in solving PISA problems, particularly in the space and shape domain. The research approach used is a qualitative approach. This type of research is qualitative descriptive approach. The study involved 27 ninth-grade students from one of Junior High School (JHS) in Kota Jambi. Data were collected through a written test using items adopted from the 2012 PISA Mathematics Released Problems, complemented by interviews to gain deeper insights. The results revealed that students’ mathematical literacy abilities were categorized into high, medium, and low levels. The results show that most students demonstrate low mathematical literacy skills. Based on the three indicators of mathematical literacy, students in the high-ability category were able to formulate mathematical models, employ geometric concepts appropriately, and interpret the results within the given context. Students in the medium category were able to perform correct procedures but were unable to derive meaningful conclusions, while students in the low category experienced difficulties in all indicators. These findings indicate that students’ mathematical literacy skills in geometry remain limited, particularly in reasoning and interpreting results. Therefore, learning activities that facilitate reasoning and provide more PISA-like tasks are needed to help strengthen students’ mathematical literacy, especially in space and shape problems. Future research may also explore the use of locally contextualized PISA-like tasks to provide students with more meaningful and relatable problem situations.

A tourism route is a sequence of tourist attractions visited. Students are familiar with tour activities and often plan tourism routes to visit several tourist attractions. Students' experience and knowledge about tourism routes can be used as a context for teaching the rule of product. Therefore, this research aims to design a learning trajectory for the rule of product using the Indonesian Realistic Mathematics Education (PMRI) approach in the Kerinci nature tourism route context. The research method used is design research with a validation study type, which consists of three stages: preparation and design, teaching experiment, and retrospective analysis. The subjects involved in this research were 11 third-semester mathematics education students at a university in Jambi, Indonesia. The instruments include learning video recordings, student work results, field notes, and test sheets. The research results show that learning trajectories designed in the context of tourism routes can help students discover, understand, and use the rule of product in solving relevant mathematical problems. The learning tracjectory consists of four activities: making a list of Kerinci tourist attractions, determining the location of several tourist attractions on a sketch map, arranging tourist attractions in tourism routes, and solving problems regarding possible tourism routes. This research shows that the designed learning trajectory is vital in helping students discover and understand the rule of product and apply them to solving relevant problems.

This study examined the mathematical reasoning abilities of elementary students at MI Salamah, in Jambi City, on the topics of patterns and geometric figures. The research was motivated by the limited number of studies that explore students’ real-time reasoning processes in elementary geometry contexts. The study aimed to describe how students with different ability levels demonstrate mathematical reasoning when solving pattern and geometry problems. A descriptive qualitative method was applied, involving three purposively selected fifth-grade students representing high, medium, and low ability levels. Data were collected through two open-ended reasoning tasks developed based on four indicators: making conjectures, performing mathematical manipulations, providing justification, and drawing conclusions. The findings revealed clear variations in students’ reasoning abilities: high-ability students demonstrated logical reasoning but had difficulty generalizing patterns; medium-ability students showed partial conceptual understanding with inconsistent justifications; and low-ability students relied on guessing without coherent reasoning. These results indicate that students tended to depend on procedural thinking rather than conceptual reasoning. The study contributes to understanding the developmental shift from procedural to conceptual reasoning and offers implications for designing instructional activities that strengthen reasoning in elementary mathematics learning.

This research investigates the combined influence of scientific attitude, active learning, and friendly character on the science learning outcomes of junior high school students in Kota Jambi. It explores how these factors contribute to student's academic performance and social development in science education. A mixed-methods approach was used, integrating quantitative data from questionnaires with qualitative insights from interviews. The sample consisted of junior high school students in Kota Jambi. Data analysis was performed using multiple regression tests with SPSS to examine the relationship between the variables. The results indicate that scientific attitude, active learning, and friendly character significantly and positively affect students' science learning outcomes. Active learning enhanced students’ engagement and critical thinking skills, while a strong scientific attitude improved their curiosity and problem-solving abilities. Students with well-developed, friendly character traits also demonstrated better social interactions, leading to more effective collaboration in group-based learning activities. Despite these positive outcomes, the study highlights the challenge of translating scientific concepts into real-world applications, which requires greater emphasis on contextual learning and motivation. This study offers a fresh perspective by integrating social-emotional traits such as friendly character into analyzing science learning outcomes, an area often overlooked in previous research. It provides actionable insights into how fostering active learning and positive social interactions can create a more engaging and effective science learning environment.

This study aims to determine students' ability to understand the prerequisite material for Pythagorean concepts. The study was conducted using a descriptive qualitative approach. The subjects of this study were students of class VIII B at SMP Adhyaksa 1 in Jambi City. Data collection involved written tests, interviews, and documentation, followed by analysis through data reduction, data presentation, and the formulation of conclusions. Data analysis was conducted based on concept comprehension indicators, namely 1) restating a concept, 2) writing down concepts in various mathematical representations, 3) using certain procedures, and 4) applying a concept. Based on the findings, of the 14 students, 7 were classified as having low comprehension, 5 were categorized at a moderate level, and 2 students achieved a high level of comprehension. This shows that students' conceptual understanding abilities vary. The results of the study show that students' conceptual understanding of the prerequisite material on Pythagoras tends to be low, with 50% in the low category. Some students showed fairly good achievement in the indicators of restating concepts and representing concepts. However, students were still weak in the indicators of selecting and using specific procedures and applying concepts.
