Abstract

. This study aims to analyze students' mathematical problem-solving abilities on similarity material based on Polya’s stages and supported by metacognitive processes. This descriptive qualitative study involved three seventh-grade students at UPTD SMPN 6 Kupang Tengah selected purposively based on ability levels: high (SKT), medium (SKS), and low (SKR). Data were collected through mathematical problem-solving tests and semi-structured interviews. The results show that high-ability students (SKT) successfully completed all stages of Polya’s problem-solving steps while demonstrating strong metacognitive regulation, including planning, monitoring, and evaluating their strategies. Medium-ability students (SKS) were able to understand the problem and plan a solution but exhibited weak monitoring and evaluation, leading to errors in executing strategies. Low-ability students (SKR) showed limited conceptual understanding and minimal metacognitive awareness, resulting in difficulties in planning, executing, and reviewing their solutions. These findings highlight that differences in students’ problem-solving performance are strongly influenced by their metacognitive skills and conceptual understanding of proportional relationships. The study emphasizes the need for learning designs that strengthen metacognitive processes and apply differentiated instructional strategies to accommodate students' varying abilities.

Abstract

Indonesian students’ mathematical literacy skills, particularly in algebra, are still relatively low, as shown by the results of PISA 2022. A significant contributing factor is the limited relevance of teaching materials to students’ real-life contexts. This study introduces an innovative approach by developing algebra teaching materials based on local wisdom—referred to as local wisdom literacy—as a meaningful context for improving mathematical literacy among seventh-grade junior high school students. The novelty of this study lies in the integration of traditional Timorese cultural practices, such as weaving patterns, local measurement systems, and indigenous numerical reasoning, into formal algebra instruction. Using the ADDIE development model, this Research and Development (R&D) study produced culturally embedded materials that were validated by experts, with validity scores of 85.4% for content and 85% for assessment instruments. The materials were also considered highly practical (96.93% by students, 96% by teachers) and effective, as indicated by a moderate average N-Gain of 0.42 in student learning outcomes. In addition to improving conceptual understanding and mathematical literacy, the developed materials serve as a culturally responsive pedagogical model that is in line with the objectives of the Merdeka Curriculum and supports the preservation of local culture. This study provides a contextual and humanistic alternative in algebra learning, which offers pedagogical value and cultural significance

Abstract

This study seeks to enhance the computational abilities of students at UPTD SMP Negeri 6 Kupang Tengah via the use of the quick calculation technique. The students' preliminary numeracy abilities remain deficient, as shown by the pre-test results, which show scores between 40 and 70, with a class average of 58%. Students struggle with fundamental arithmetic operations and the resolution of contextual difficulties. This study used a qualitative descriptive methodology, with 10 students as participants. The intervention was conducted using microlearning activities, quick calculation exercises, numerical games, and individualized tuition over a period of roughly two months. The post-test findings indicated a substantial improvement, with student scores ranging from 76 to 91 and the class average rising to 84.6%. All pupils attained mastery of the learning goals. This discovery indicates that the quick calculation approach enhances pupils' comprehension of numerical patterns, precision, and calculation speed. This approach has shown applicability in schools with constrained resources. The quick calculation approach serves as an alternate learning strategy both straightforward and efficacious for enhancing pupils' calculating abilities.

Abstract

OSN is an activity that comprehensively develops a culture of learning, creativity, and motivation to achieve. However, the lack of knowledge among teachers and students about mathematics Olympiad questions has resulted in poor performance. The purpose of this community service activity is to equip teachers with basic skills and techniques in understanding Olympiad material so that they can guide students to acquire the skills to solve Olympiad questions. The methods used were lectures, discussions, and simulations. The results obtained from this activity were very effective, as demonstrated by an increase in the average score from 32.33 on the pretest to 85.67 on the posttest, indicating significant progress in mastery of concepts and basic skills in solving Olympiad questions. In addition to improving academic abilities, the results of the evaluation through questionnaires showed that participants were satisfied with the implementation of the activity, both in terms of material and delivery methods. Participants gained new insights and strategies in solving Olympic questions, which had an impact on increasing their confidence and motivation. Similar community service activities in the future need to be designed with a stronger focus on the basic understanding stage so that the results achieved can be more optimal and evenly distributed.

Abstract

Mathematics instruction in Indonesia continues to encounter difficulties in cultivating students’ problem-solving abilities, particularly in topics related to algebraic expressions. This study seeks to examine instructional needs and to develop a problem-solving-oriented Student Worksheet (LKPD) tailored to algebraic form content. The research took place at SMP Negeri 6 Kupang Tengah Satu Atap, employing a Research and Development (R&D) methodology with a focus on the analysis and design phases of the ADDIE model. The participants were seventh-grade students. Data collection methods included classroom observations, teacher interviews, and document analysis. The analysis reveals that instruction remains predominantly teacher-centered, relying heavily on lectures, with low student engagement and a lack of supportive instructional media for fostering problem-solving. In response, a student worksheet was designed that incorporates Polya’s problem-solving framework and draws upon Kupang’s local context to enhance students’ problem-solving skills. This article reports on the needs assessment and the initial development of the worksheetTop of FormBottom of Form LKPD as the first step in developing contextual and meaningful teaching materials
