Abstract

This study investigates the individual and collaborative designs of context-based numeracy tasks developed by mathematics teachers employing three different contexts, namely, Islamic inheritance law, population census, and genetics. The tasks were designed at different levels of knowing, applying, and reasoning. The obtained data were analyzed using PISA’s contextual framework and Indonesia’s cognitive taxonomy to evaluate task solvability, context type, context level, and cognitive demand. The results show significant differences: most individual designs remained at the knowing level (88.23%), had first-order contexts (88.23%), and had 19.05% of tasks that could not be solved due to insufficient information. Collaborative designs eliminated all tasks that could not be solved, increased the number of reasoning-level tasks from 7.84% to 24.39%, and removed all zero-order context levels. Both preferred social settings (52%), but collaborative designs showed more integration. For example, context-based numeracy problems created individually ask students to determine the percentage of Generation Z. In contrast, group-created problems ask them to analyze the impact of demographics on planning. These findings demonstrate the importance of teacher collaboration in increasing the authenticity and complexity of learning activities. Systematic collaboration frameworks should be incorporated into teacher professional development programs.

Abstract

Indonesian Migrant Workers (PMI) in Brunei Darussalam face limited access to continuing education, lack of entrepreneurial skills, and insufficient understanding of the integration between education, ecology, and business. To address this gap, the FMIPA team from Universitas Negeri Surabaya conducted an online EduEcopreneurship training in November 2025. The activity employed a participatory workshop approach and a pretest-posttest evaluation design. Results indicated a significant improvement in participants’ conceptual understanding, with average scores rising from 52.4 to 84.2 (a 31.8-point increase, or 60.7%). Moreover, 93.3% of participants successfully designed business ideas that integrated the three core pillars of EduEcopreneurship: Eco-Innovation, Eco-Opportunities, and Eco-Commitment. Participant feedback was rated “Good” (average 4.08 on a 5-point scale). These findings confirm that EduEcopreneurship serves as an effective dual empowerment model,combining non-formal education and sustainable economic development,for migrant workers.

Abstract

The lack of integration of local culture into mathematics teaching, which is usually procedural and abstract in nature, is an obstacle to creating valuable, reflective learning experiences that are appropriate for the educational needs of the 21st century. This study aimed to analyze the validity of ethnomathematics-based lesson plan using the Discovery Learning model and Deep Learning approach in the mystery of the Pythagorean Theorem. The methodology applied is research and development (R&D) using a modified 4D model, focusing on the Develop (D3) stage, involving three validators: an expert lecturer in the subject matter and two mathematics teachers from junior high school as implementers. The evaluation instruments consisted of five aspects: content validity, presentation, language use, integration of the learning model, and technical validity. The results of the validation process indicated that the module is highly valid, with Aiken V values ranging from 0.75 to 1.00. This ethnomathematics-based lesson plan with Pythagorean Theorem material successfully links mathematical concepts with local culture, presents an organized and communicative learning structure, and encourages student exploration and reflection very well. These findings confirm that this learning tool is suitable for use in contextual learning of Pythagorean Theorem material. Future researchers are advised to evaluate the effectiveness of this lesson plan through its application in the classroom and to develop similar teaching tools for other materials that are in line with the local context of students.
