Abstract

Rendahnya kemampuan literasi matematis siswa sangatlah berpengaruh pada hasil belajar siswa pada topik aritmetika sosial. Hal ini juga dikarenakan kurangnya desain pembelajaran yang berorintasi pada permasalahan kehidupan sehari-hari siswa. Tujuan penelitian ini adalah untuk meneliti lintasan belajar siswa dalam pembelajaran aritmatika sosial melalui Hypothetical Learning Trajectory yang didesain dengan menggunakan pendekatan Pendidikan Matematika Realistik Indonesia konteks permainan monopoli. Penelitian dilaksanakan di SMP Negeri satu Tomohon pada kelas VII E sebagai kelas pilot experiment dan kelas VII F sebagai kelas teaching experiment. Penelitian ini menggunakan metode penelitian design research yang terdiri dari tiga tahap pelaksanaan yaitu merancang aktivitas pembelajaran, melaksanakan pembelajaran dan melakukan analisis retrosepektif . Teknik pengumpulan data dilakukan dengan observasi, dokumentasi dan video, data tertulis dan juga wawancara. Kemudian HLT yang didesain dibandingkan dengan kegiatan siswa yang sebenarnya terjadi di dalam kelas saat proses pembelajaran berlangsung, sehingga di tahap analisis retrospektif didapatkan lintasan belajar siswa akhir dari HLT ke Local Instruction Theory. Hasil penelitian menyimpulkan bahwa lintasan belajar yang telah didesain dari kegiatan pembelajaran di kelas menggunakan konteks permainan monopoli dapat membantu siswa dalam menyelesaikan permasalahan aritmatika sosial pada level formal dengan menggunakan pengetahuan dan pengalaman mereka di level situsional, referensial dan general.

Abstract

The development of Pancasila Student Profiles in Indonesia must be carried out from an early age. This needs to be done simultaneously with the help of teachers and parents as the spearheads in learning in the classroom and at home. This community service activity focuses on empowering teachers to develop projects to strengthen Pancasila student profiles based on ethnorealistic. Ethnorealism was chosen because it is suitable for learning in early childhood and is close to the context of local wisdom that is close to students. The implementation of this service uses the methods of socialization, training, application of technology, mentoring evaluation, and program sustainability. The results obtained include the development of ethnorealistic-based educational props as a learning medium, especially in developing projects to strengthen Pancasila student profiles at Menara Perlindungan Kindergarten. In addition, teachers at the Mitra School (Tower Protection Kindergarten) can develop projects to strengthen Pancasila student profiles based on ethnorealism. Then, in this service, there is also an increase in Pancasila values ​​in students' personalities through the learning activities that have been carried out

Abstract

Numeracy skills are essential for students today. However, there are still many students who still need to improve their numeracy abilities. Topics such as social mathematics require high numeracy skills. This research aims to produce a local instructional theory on social arithmetic material using the sociodrama method with the PMRI approach. This research was conducted at SMP Negeri 2 Tondano, with research subjects in classes XI MIA 1 (Pilot Experiment Class) and XI MIA 2 (Teaching Experiment Class). The research method used is the design research method, which includes preliminary design, teaching experiment, and retrospective analysis. This research collected data through video recordings, documentation, field notes, and observations. Meanwhile, the data was analyzed using qualitative analysis. The research results show that the resulting LIT is valid, practical, and effective for students studying social arithmetic topics. On the other hand, there is an increase in formal mathematics abilities, as demonstrated by students' conceptual understanding of how to apply their knowledge and experience when solving problems at the situational, referential, and general levels. Therefore, using the sociodrama method with the PMRI approach, the social arithmetic learning design is instrumental in increasing students' understanding and motivation in learning mathematics on social arithmetic material.

Abstract

This research aims to examine the factors that influence the ability of class IX junior high school students in Kotamobagu City, North Sulawesi Province, Indonesia, to solve story problems, both theoretical and applied. A total of two hundred and four students in the 2023/2024 academic year were selected using a double-phased cluster sampling technique. The research instrument used in this research was theoretical and applied mathematics story test questions created by researchers. The data obtained were analyzed using path analysis. The results of the analysis show that solving theoretical and applied mathematics story problems shows the same tendency, which is influenced both directly by mathematical numerical and verbal abilities and indirectly by the ability to create mathematical models. From these results, teachers must strive to improve numerical and verbal mathematical abilities because these two abilities, directly or indirectly through the ability to create mathematical models together, can improve students' abilities in solving theoretical and applied word problems.

Abstract

This study investigated the relationship between students' mathematical creative thinking skills and their performance in solving mathematical literacy problems. The aim of this research is to understand how students' creativity affects their ability to solve open-ended problems, as well as improve their mathematical literacy. The research design of a qualitative case study was used by involving 30 grade VIII students who were tested through creativity tests and mathematical literacy tasks. The results showed that students with high creative thinking skills were able to demonstrate flexibility, originality, and fluency in problem-solving, which allowed them to apply mathematical concepts in real-life contexts. In contrast, students with low creativity tend to use more mechanical and limited methods of problem-solving. This research highlights the importance of an open-ended, problem-based approach to improving mathematical literacy by developing students' creativity. These findings have implications for developing teaching strategies to facilitate mathematics creativity. Further research should examine integrating technology and other innovative teaching methods to improve students' creative problem-solving skills.

Abstract

This study aimed to develop a competency-based performance evaluation model for mathematics teachers at the junior secondary level. Recognizing the crucial role of teacher quality in student achievement, the study focused on measurable aspects of performance, including content mastery, instructional management, and professional commitment. A quantitative approach was employed using a research and development (R&D) framework, supported by a quasi-experimental design with pretest-posttest control groups. Data were collected via structured questionnaires, classroom observations, interviews, and expert validations through focus group discussions. Statistical analyses included descriptive statistics, ANOVA, t-tests, and confirmatory factor analysis using SPSS and LISREL. The results indicated that the developed model effectively differentiated teacher performance across various school categories, with 45% categorized as good, 53% adequate, and 2% poor. Student achievement was positively correlated, with 82% achieving the minimum competency threshold. The factor analysis confirmed a valid measurement model: F1 = 0.505ZX1 + 0.475ZX2 + 0.308ZX3, explaining 57.92% of the variance in teacher performance. The findings suggest that teacher evaluation must integrate multidimensional competencies and contextual factors to be accurate and actionable. This study contributes a validated, data-driven evaluation framework aligned with national standards and global educational expectations, offering practical implications for policy, supervision, and teacher development.
