Abstract

This study aims to find out the difficulties of students in solving PLSV problems using the demonstration method for grade VII students of SMP Negeri 5 Lamboya. This study uses a qualitative approach with a descriptive method. 14 students as subjects to be researched to the extent to which the students can work on one-variable lienar equation problems. The data collection methods used are tests, interviews, and documentation. Data analysis is carried out qualitatively with the stages of data reduction, data presentation, and conclusion drawing. The results of the study showed that there was still a lack of ability of students to solve PLSV questions that answered the questions correctly and incorrectly. The results of the analysis for problems number 1, 2 and 3 were at the stage of difficulty in interpreting mathematical language (59.66%), the stage of difficulty in using data (64.33%), the stage of difficulty in mastering concepts correctly (66.66%), the stage of difficulty in using calculation operations (66.66%), and the stage of difficulty in drawing conclusions (83.33%). The cause of incompetence is that students do not read the questions carefully so that they make mistakes in writing down what is known and what is asked, so that they are less able to solve problems, in a hurry so that others are incomplete.

Abstract

This study aims to explore the concept of ethnomathematics found in the movement patterns of the Woleka dance in Gollu Togo, West Wewewa. The research method used is a qualitative approach with data collection techniques through observation, interviews, and documentation. The interview subject in this study was the adat leader (rato adat). This study also used data analysis techniques that include data reduction, data presentation, and drawing conclusions. The results show that the Woleka dance has systematic and repetitive movement patterns that reflect mathematical concepts such as symmetry, repeating patterns, and geometric transformations. In addition, cultural artifacts present in the Wewewa community also demonstrate the application of planar and spatial geometric concepts. This research is expected to contribute to culturally based mathematics teaching and to increase appreciation for local cultural richness

Abstract

Political education plays a crucial role in shaping citizens' awareness of their rights, obligations, and participation in a democratic society. This study aims to analyze the role of political education in raising citizen awareness and identify effective approaches to political education to support public political participation. The study employed a Systematic Literature Review (SLR) method for reviewing scientific articles published between 2015 and 2025. The review process involved identification, screening, eligibility assessment, and article selection based on established inclusion and exclusion criteria. Literature meeting the criteria was then analyzed using thematic analysis to identify patterns, themes, and trends in the research findings. The study's findings indicate that political education conducted in a critical, participatory, and contextual manner can enhance political understanding, awareness of citizens' rights and obligations, and public participation in the democratic process. Conversely, a one-way and doctrinal approach tends to result in limited political understanding. The findings also indicate that quality political education contributes to strengthening democratic culture at both the local and national levels. Therefore, strengthening political education through formal and non-formal education needs to be a priority in developing civic education policies.

Abstract

Kegiatan pengabdian kepada masyarakat ini dilatarbelakangi oleh rendahnya pemahaman konsep dan tingginya kecemasan matematika siswa. Tujuan kegiatan ini adalah membentuk Komunitas Belajar Matematika Kreatif bagi siswa SMP–SMA di Asrama Putri Seraphine. Subjek kegiatan berjumlah 18 siswa yang dilibatkan dalam pendampingan intensif selama dua bulan dengan mengintegrasikan pendekatan guided discovery learning, problem-based learning, dan math talk learning community. Kegiatan diawali dengan pemberian pretest untuk mengetahui kemampuan awal siswa, kemudian dilanjutkan dengan aktivitas pembelajaran kolaboratif berupa diskusi kelompok, pemecahan masalah kontekstual, permainan edukatif, serta tutor sebaya. Evaluasi dilakukan melalui posttest dan observasi selama kegiatan berlangsung. Hasil menunjukkan adanya peningkatan kemampuan pemahaman matematika siswa, dengan rata-rata skor meningkat dari 14,06 (38,0%) menjadi 27,83 (75,23%). Selain itu, siswa menunjukkan peningkatan keaktifan, kepercayaan diri, dan keterlibatan dalam pembelajaran. Namun, kemampuan penalaran matematis siswa masih belum berkembang secara optimal, terutama dalam menjelaskan langkah penyelesaian secara sistematis. Dengan demikian, pembentukan komunitas belajar matematika kreatif terbukti efektif dalam meningkatkan pemahaman konsep dan keterlibatan siswa. Namun, diperlukan upaya lanjutan untuk mengembangkan kemampuan penalaran matematis secara lebih optimal.

Abstract

This study aimed to determine the effectiveness of a numeracy matriculation course on the numeracy skills of first-year students at Universitas Katolik Weetebula in the 2025–2026 academic year. A quantitative approach with a one-group pretest–posttest design was used. The sample comprised 681 new students who participated in the numeracy matriculation program. Data were collected through pretest and posttest instruments and analyzed using a paired-sample t-test and N-gain. The mean pretest score was 49.56, which increased to a mean posttest score of 69.43. The t-test yielded a significance value of 0.000 (< 0.05), indicating a significant difference in numeracy skills before and after matriculation. The N-gain value of 0.39 was classified as moderate, indicating that the matriculation effectively improved numeracy skills. Limitations include the lack of a control group, reliance solely on quantitative instruments, and absence of long-term retention measurement. Future research is recommended to use comparative or quasi-experimental designs, incorporate qualitative data (interviews/observations) to explore the learning process, and conduct follow-up studies to evaluate long-term effects of matriculation.
