AbstractThe low PISA results of students in Indonesia are caused by students' lack of familiarity in solving PISA-characteristic problems, especially in the content of uncertainty and data. To overcome this, learning needs to familiarize students with the PISA problem-solving method. Therefore, this study aims to develop PISA-type mathematics problems with uncertainty and data content using the context of the Siginjai Jambi Museum for junior high school students that are valid, practical and have a potential effect on students' mathematical literacy. The research method used is Design research type development study. The questions were developed in three stages, namely the preliminary stage, the formative evaluation stage, and the assessment phase. The subjects of this study were 26 students of Secondary School Number 4 Kota Jambi. Data were collected by interview, test, and questionnaire. The data shows a percentage of 78.7% valid category for question validity, with a percentage of 78.5% practical category for practicality at the one-to-one stage and for a percentage of 84% very practical category for practicality at the small group stage. The results of this study are PISA type mathematics questions with uncertainty and data content with the Jambi context for junior high school students that are valid and practical. Furthermore, the questions generated have a potential effect on students' mathematical literacy.

Mathematics results in junior high schools are usually not very good as teaching usually focuses on the teacher, so limiting their participation in learning. This study aimed to find out how the Jigsaw collaborative learning approach affects pupils' math achievement on the Pythagorean Theorem subject. Using a quantitative approach, the study included only a post-test for the control group in a quasi-experimental design. All the participants were eighth graders at SMP Negeri 26 Jambi City in the 2025–2026 academic year. With a total of 60 pupils, students were picked using cluster random sampling, therefore one class learned via the Jigsaw approach and another got Direct Instruction. A math test helped to collect the data that was then analyzed with both descriptive and inferential statistics. The normality test revealed that both groups exhibited a normal distribution; the homogeneity test confirmed comparable variances. The independent samples t-test revealed a significant difference between the experimental and control groups (t = 3.555, p < 0.001). Students who learned using the Jigsaw approach had an average score of 83.30, whereas those who received Direct Instruction had an average score of 76.77. These findings point to a major rise in math performance among pupils using the Jigsaw approach of collaborative learning. So, particularly in learning the Pythagorean Theorem, the Jigsaw approach might be seen as a useful substitute teaching approach for improved learning outcomes.

This community service program aimed to enhance teachers’ understanding of the conceptual framework of the Programme for International Student Assessment (PISA) and improve their skills in developing locally contextualized assessment items. This program was implemented using a community-based action research approach, involving systematic stages of planning, action, observation, and reflection carried out collaboratively with participating teachers. The activity responded to teachers’ limited ability to design questions requiring critical thinking and problem-solving, as well as their lack of experience in applying contextual tasks in classrooms. The program involved conceptual framework dissemination, training and mentoring on item development, classroom implementation, and evaluation through pre-tests, post-tests, response sheets, and classroom observations. Twenty-one participants, including teachers from Al-Arief Islamic schools and students from Jambi University, actively engaged in all stages. Results showed an increase in average scores from 2.62 to 4.04, with an N-Gain of 0.60 (moderate). Teachers’ knowledge, experience with assessment tasks, and problem-solving strategies all improved significantly. The novelty lies in integrating local contexts into item design, which strengthened teachers’ conceptual understanding and readiness for classroom implementation. The training proved effective in building teachers’ capacity and supporting more relevant and contextual teaching practices.

Despite the recognized importance of inductive and visual-spatial reasoning in geometry learning, little is known about how these abilities manifest and interrelate in junior high school students' problem-solving, particularly in the Indonesian context. This study aims to describe students' inductive reasoning and visual-spatial abilities and explore their relationship in solving plane geometry problems. A descriptive qualitative approach was employed, with data collected through written tests, semi-structured interviews, and documentation involving 25 ninth-grade students from a public junior high school in Jambi City, Indonesia. The instruments were based on indicators of inductive reasoning (pattern identification, conjecturing, and generalization) and on visual-spatial ability (imagination, conceptualization, and visual problem-solving). Data were analyzed through reduction, display, and conclusion drawing, with triangulation to ensure validity. The results indicate that students' inductive reasoning is relatively low, particularly in generalization, while visual-spatial ability is relatively stronger, especially in imagination and conceptualization, though difficulties remain in visual problem-solving. Cross-case analysis reveals a thematic relationship between the two abilities, with stronger visualization skills supporting pattern identification and conjecture formation. Therefore, mathematics learning should facilitate activities that promote pattern exploration and visualization to develop both abilities.
