Abstract

Introduction (background): One of the government's steps to restore learning due to the Covid 19 pandemic is to issue a policy on the use of the Independent Learning Curriculum (KMB). However, in its implementation, schools are given the freedom to implement the curriculum in accordance with school conditions. St. Aloysius Niki-Niki Catholic Private Junior High School is in the IKM Mandiri Belajar category. This shows that KMB implementation has not been optimal. This is because this platform has only been used by schools since August 2022. In addition, schools are constrained by the categorization given which limits the school's space to implement KMB. Purpose of activities: One way that can be used to accelerate SMIs is to maximize the use of PMM. PMM comes with a high-tech approach that can help teachers in obtaining references, inspiration, understanding, and training independently to implement the Independent Curriculum. Method of activity: Pengabdi optimizes the use of PMM to teachers by providing training on the use of PMM. This activity was attended by the Principal and 19 teachers. In addition to providing guidance containing PMM, the service team also provides questionnaires at the end of activities as part of feedback on service activities. Results of activities: PMM optimization activities are also considered very interesting because 80% of teachers are new to this kind of training, even though 60% of teachers take a long time to explore PMM. This is due to the unstable internet network and teachers are not used to using this platform. However, the results of the St. Aloysius Niki-Niki Catholic Junior High School Education report card also provide promising results regarding teacher participation in the use of PMM where the participation rate in 2022 is 10, increasing by 622% in 2023 to 72.2. This makes this school in the top ranking category at the Regency / City level and in the upper middle category nationally. Conclusion: This kind of mentoring activity for teachers is very necessary considering that teachers also need additional insight and sharing experiences about IKM. The teachers have also committed to continue to optimize the use of PMM and will change the status of SMIs to Mandiri Change, in 2024.

Abstract

This study explores differences in numeracy between junior high school students with Field-Dependent (FD) and Field-Independent (FI) cognitive styles. Using a qualitative descriptive approach, the study was conducted in two junior high schools in Kefamenanu, West Timor, Indonesia. Forty students, evenly distributed across the two schools, participated in the study. Data were collected through numeracy tests and in-depth interviews to examine students’ performance across three numeracy components: understanding, application, and reasoning. The findings reveal that students with an FI cognitive style generally demonstrated competence in all three components, although some experienced difficulties in reasoning tasks requiring critical evaluation and formal justification. In contrast, students with an FD cognitive style tended to achieve only the understanding and application components and faced persistent challenges in progressing to the reasoning component. These results highlight the importance of differentiated numeracy instruction. FD students benefit from visual representations, explicit guidance, and collaborative learning to strengthen foundational, whereas FI students require non-routine and argumentative tasks to enhance higher-order reasoning. This study recommends that educators and future researchers implement inclusive numeracy literacy practices aligned with students’ cognitive styles.

Abstract

Pemanfaatan alat peraga merupakan salah satu cara efektif dalam meningkatkan kemampuan matematis siswa. Alat peraga biasanya didesain dengan sederhana, menarik, mudah digunakan dan mudah dieksplorasi sehingga memudahkan siswa dalam penggunaan dan proses menemukan sendiri kesalahannya dan memperbaikinya. Alat peraga dapat menjadi solusi terutama dalam mengatasi rendahnya nilai Matematika siswa. Penyebab rendahnyaa tingkat kemampuan matematis ini selain disebabkan karena perbedaan kemampuan kognitif siswa, juga disebabkan karena siswa berasal dari Sekolah Dasar yang berbeda-beda. Solusi yang ditawarkan tim pengabdian adalah dengan memberikan pendampingan pembuatan alat peraga bagi guru-guru SMPN Kota Baru. Pengabdi juga melakukan pembelajaran dengan memanfaatkan alat peraga yang telah dirangkai yaitu Papan Dakon dan Dakota sebagai bagian dari pendampingan bagi siswa. Pengabdi meyakini bahwa kesuksesan pembelajaran pada jenjang SMP ini dimulai dengan penguasaan pada materi awal seperti Bilangan Bulat. Oleh karena itu pengabdian ini merupakan salah satu solusi yang diyakini dapat meningkatkan kemampuan matematis siswa. Hal ini dibuktikan dengan nilai Pre-Test dan Post-Test yang memberikan hasil bahwa penggunaan alat peraga Papan Dakon dan Dakota memberikan dampak positif bagi peningkatan hasil belajar siswa dalam operasi hitung bilangan bulat. Hasil pengujian rata-rata nilai Pretest dan Posttest menggunakan software SPSS juga memberikan hasil bahwa nilai Pretest yang dihasilkan lebih rendah dibandingkan dengan nilai Posttest yang semakin meyakinkan bahwa penggunaan alat peraga meningkatkan kemampuan matematis siswa pada operasi hitung bilangan bulat.

Abstract

Mata pelajaran matematika diajarkan di tingkat Sekolah Dasar (SD) hingga Perguruan Tinggi (PT). Salah satu tantangan dalam pembelajaran matematika adalah bagaimana seorang pengajar dapat memberikan pemahaman yang baik agar siswa/mahasiswa tersebut dapat mengerti apa yang dijelaskan, sehingga tidak muncul kesan yang negatif saat belajar matematika. Pada SDK Yaswari Niki-niki III masih banyak kesulitan yang ditemui dalam penguasaan siswa terhadap materi geometri. Salah satunya adalah karena kurangnya penggunaan media atau alat peraga yang dapat membantu siswa memahami konsep geometri sehingga materi yang disampaikan bersifat abstrak dan menimbulkan kejenuhan bagi sebagian besar siswa. Kegiatan pendampingan ini ditujukan untuk mengenalkan Permainan Tangram  sebagai alat bantu pembelajaran matematika yang dilaksanakan di SDK Yaswari Niki-niki III sehingga siswa/i mampu memahami konsep matematika dalam materi bangun datar dan meningkatkan kreativitas dan siswa-siswi dalam mempelajari konsep Geometri. Hal ini terlihat dari keterlibatan siswa/i yang begitu kreatif dalam pembelajaran yang ditantang untuk menggabungkan, membagi dan mengatur ulang potongan-potongan tangram yang sudah diacak oleh tim pengabdi. Hal ini dapat dibuktikan juga dari hasil pretest dan posttest meningkat yakni kemampuan siswa dalam menyelesaikan soal sebelum dan sesudah mengikuti pembelajaran dengan media tangram dengan rata-ratanya adalah adalah dari 38,57 % meningkat menjadi 63,33%.

Abstract

The low numeracy skills of students in Indonesia remains a major challenge in many schools, including Junior high school students in the border area of ​​the Republic of Indonesia and the Democratic Republic of Timor Leste. The purpose of this study is to describe the level of students’ numeracy skills, identify aspects that still need improvement, explore the factors affecting students’ numeracy skills, and examine the efforts made to support numeracy development among junior high school students. This study employs a qualitative research design with a case study approach, conducted at one Junior High School in Kefamenanu City, Indonesia, during the odd semester of the 2024/2025 academic year. The participants were 21 eighth-grade students who completed a written test, followed by interviews with six students, their parents, and the mathematics teacher. Test items and interview guidelines were used to collect data. Results indicate that students’ numeracy skills are still relatively low, as reflected in the low average test scores. The numeracy aspects that require the most improvement are application and reasoning. Factors influencing numeracy skills include internal factors-such as interest, motivation, understanding, and attitude-and external factors, including the learning environment, facilities and infrastructure, parental involvement, and teaching strategies. Efforts to enhance numeracy skills include increasing students’ interest and motivation, strengthening conceptual understanding, developing application and reasoning skills, and implementing context-based learning strategies

Abstract

This article describes the results of community service activities targeting students of Kiupukan State Elementary School, with the goal of enabling teachers to utilize varied and engaging learning media, such as concrete materials, to enhance mathematics learning outcomes. The concrete media used were teaching aids in the form of number rulers and number cards on the topic of integers. The number line and number cards were chosen as an alternative to overcome the problem, because they can help students understand the addition and subtraction of integers. In addition, they can also concretize the addition and subtraction of integers, which are abstract concepts. This research method was implemented through several stages, namely the preparation stage, implementation, and evaluation of the activity. The results of this community service activity were an increase in students' understanding at SDN Nispukan from a score of 22 before the activity to 77.8 after the activity. While at SDK, Kiupukan went from a score of 22 to 60.4. This Community Service activity needs to be carried out further on other abstract mathematics topics, but still using teaching aids.

Abstract

Addressing complex problems requires multiple and sustainable solution strategies, highlighting the importance of students’ numeracy literacy. However, existing assessment practices often fail to capture students’ higher-order thinking and problem-solving flexibility, particularly in algebraic contexts. An open-ended, locally wisdom–based instrument is considered appropriate for fostering students’ problem-solving abilities; however, it is rarely implemented in regular classroom instruction. Furthermore, research on the development of open-ended numeracy literacy instruments within Timorese culture remains limited. This study aims to develop and validate an open-ended numeracy literacy instrument in the algebra domain to address this gap. The study employed a design-based development approach using Tessmer’s formative evaluation, which includes preliminary study, expert review, one-to-one, small-group, and field-test stages. Qualitative data were obtained from expert validation, student feedback, and interviews, while quantitative data were collected through student response questionnaires and test results. The findings reveal that the developed instrument meets the criteria of validity, practicality, and reliability. Furthermore, the instrument demonstrates moderate difficulty and acceptable discrimination, indicating its effectiveness in distinguishing students’ abilities. This study contributes a valid and reliable open-ended assessment tool that can support the enhancement of students’ numeracy literacy and promote meaningful mathematics learning in algebra.
