Abstract

Numeracy literacy skills are basic competencies that need to be developed in junior high school (SMP) students in the 21st century. However, mathematics learning in schools has not yet linked the concept of mathematics to the cultural context in daily life. This research aims to develop Student Worksheets (LKPD) in the Context of Tabut Culture with a valid and practical STEAM approach to facilitate students' numeracy literacy. This research uses the Research and Development (R&D) method with a 4D development model comprising define, design, and develop stages, while the disseminate stage is not carried out. The research subjects included 31 students and 1 mathematics teacher in grade VII of SMPN 1 Kepahiang. The research instrument consists of validation sheets and questionnaires on the practicality of students and teachers. The study's results showed that the LKPD developed had a validity rate of 87.83% in the very valid category. The results of the practicality test showed that 80.67% of students were in the practical category, and 82.27% of teachers were in the very practical category. These findings show that LKPD, in the context of Ark Culture with a STEAM approach, is suitable as innovative teaching materials to support contextual mathematics learning and improve students' numeracy literacy.

Abstract

Mathematical critical thinking ability is the capacity to investigate, discover, connect, and assess every aspect of a problem carefully and thoughtfully to arrive at the best solution. This study aims to describe students' mathematical critical thinking abilities regarding circles in Grade VIII at SMP Negeri 09 Lebong. This research is a qualitative descriptive study with 20 student participants. Three students were interviewed: one with high ability, one with medium ability, and one with low ability. Data collection methods included tests, interviews, and documentation. The research instruments consisted of test items and interview guidelines. The data analysis technique involved data collection, data reduction, data presentation, and conclusion. The results of the study show that high-ability students met all indicators of mathematical critical thinking: Interpretation, Analysis, Evaluation, and Conclusion. Medium-ability students met two indicators: Interpretation and Analysis. Low-ability students were unable to meet the indicators of mathematical critical thinking: Interpretation, Analysis, Evaluation, and Conclusion.

Abstract

This research was motivated by the low mathematical problem-solving ability of eighth-grade students at SMPN 15 Bengkulu Utara on the topic of linear equations and inequalities of one variable, as indicated by an average score of 40. In addition, the Student Worksheets (LKPD) used in the classroom are not contextual, less engaging, and have not optimally facilitated the development of students’ problem-solving skills. Therefore, this study aims to develop intercropping context-based LKPD that are valid and practical in facilitating students’ mathematical problem-solving abilities. This research employed a development research approach using the 4D model adapted into three stages, namely define, design, and develop. The study was conducted at SMPN 15 Bengkulu Utara. The research subjects consisted of 10 students of class VIII B in the limited trial and 23 students of class VIII A in the field trial during the 2025/2026 academic year. The research instruments included expert validation sheets as well as teacher and student response questionnaires. The collected data were analyzed using descriptive quantitative techniques through percentage calculations to determine the validity and practicality levels of the developed product.The results showed that the intercropping context-based LKPD obtained a validity percentage of 90.18% from experts, which falls into the highly valid category. Meanwhile, the practicality results indicated that the LKPD achieved a score of 93.33% based on teacher responses and 88.15% based on student responses, both categorized as highly practical. Therefore, the developed LKPD is considered valid and practical for facilitating students’ mathematical problem-solving skills.
