Abstract

This study aims to understand the cognitive development of mathematics education students based on Piaget's theory in terms of gender differences. This research method is descriptive quantitative research with the research subjects being students of mathematics education at Timor Universities. Students' cognitive development was measured using the Logical Operations Test (LOT), which consisted of 14 numbers. LOT questions are given to students, the results are analyzed and described. The results showed that the cognitive development stage for females was 19.18% in the initial concrete stage, 36.99% in the final concrete stage, 13.70% in the initial formal stage and 1.37% in the final formal stage. Male at 9.59% in the initial concrete stage, 6.85% in the final concrete stage, 9.59% in the initial formal stage and 2.74% in the final formal stage. Meanwhile, students' understanding based on seven logical operations is in low understanding for each type.Penelitian ini bertujuan untuk  mengetahui perkembangan kognitif mahasiswa pendidikan matematika berdasarkan teori Piaget ditinjau dari perbedaan jenis kelamin. Metode penelitian ini adalah penelitian deskriptif kuantitatif dengan subjek penelitian adalah mahasiswa pendidikan matematika Universitas Timor. Perkembangan kognitif mahasiswa diukur dengan menggunakan Tes Operasi Logis (TOL) yang berjumlah 14 nomor. Soal TOL diberikan kepada mahasiswa, hasilnya dianalisis dan dideskripsikan. Hasil penelitian menunjukkan bahwa tahap perkembangan kognitif sebesar 19,18% tahap konkret awal, 36,99 % tahap konkret akhir, 13,70% tahap formal awal dan 1,37% tahap formal akhir bagi mahasiswa perempuan. Sementara hasil pemetaan tahap perkembangan kognitif sebesar 9,59% tahap konkret awal, 6,85 % tahap konkret akhir, 9,59% tahap formal awal dan 2,74% tahap formal akhir bagi mahasiswa laki-laki. Sementara itu pemahaman mahasiswa berdasarkan 7 operasi logis berada dalam pemahaman rendah untuk masing-masing tipe.

Abstract

Abstrak Pembelajaran Statistika di tingkat SMP sering dianggap sulit oleh siswa karena penyajiannya yang cenderung abstrak dan kurang kontekstual. Kondisi ini juga dialami oleh siswa SMP Satu Atap Negeri Maumolo, khususnya di kelas VIII, yang menunjukkan rendahnya pemahaman konsep dasar Statistika. Oleh karena itu, kegiatan pengabdian kepada masyarakat ini bertujuan untuk mengembangkan dan menerapkan modul interaktif sebagai media pembelajaran yang dapat meningkatkan pemahaman siswa. Mitra kegiatan adalah SMP Satu Atap Negeri Maumolo dengan sasaran 30 siswa kelas VIII yang mengikuti kegiatan selama dua hari, pada tanggal 1 dan 2 Agustus 2025. Metode pelaksanaan meliputi penyusunan modul interaktif, penyampaian materi berbasis kontekstual, diskusi, serta pendampingan dalam mengerjakan latihan soal. Hasil kegiatan menunjukkan peningkatan pemahaman siswa yang terlihat dari peningkatan rata-rata nilai latihan dari 58 pada awal kegiatan menjadi 80 setelah penggunaan modul. Secara kualitatif, siswa menyatakan modul mudah dipahami, tampilannya menarik, serta membantu meningkatkan kepercayaan diri dalam mempelajari Statistika. Lebih dari 85% siswa terlibat aktif dalam diskusi dan mampu menyelesaikan soal dengan baik. Dengan demikian, kegiatan ini memberikan dampak positif dalam mendukung peningkatan kualitas pembelajaran Statistika dan dapat dijadikan model alternatif pembelajaran bagi sekolah-sekolah di wilayah perbatasan. Kata kunci: Pengabdian masyarakat; modul interaktif; statistika; pemahaman siswa; SMP. Abstract Statistics learning at the junior high school level is often perceived as difficult by students due to its abstract presentation and lack of contextual approaches. This condition is also found among eighth-grade students of SMP Satu Atap Negeri Maumolo, who demonstrate limited understanding of basic statistical concepts. Therefore, this community service activity aimed to develop and implement an interactive module as a learning medium to improve students’ comprehension. The partner institution was SMP Satu Atap Negeri Maumolo, involving 30 eighth-grade students who participated in the program over two days, on August 1–2, 2025. The implementation methods included the development of the interactive module, contextual delivery of materials, group discussions, and guided practice in solving problems provided in the module. The results indicated an improvement in students’ understanding, as reflected in the increase of average practice scores from 58 at the beginning of the activity to 80 after the module was applied. Qualitatively, students reported that the module was easy to understand, visually engaging, and helpful in building their confidence in learning Statistics. More than 85% of students actively engaged in discussions and successfully completed the exercises. In conclusion, this activity had a positive impact on improving the quality of Statistics learning and can serve as an alternative model for schools in border regions. Keywords: community service; interactive module; statistics; student comprehension; junior high school.

Abstract

The purpose of this community service activity is to provide socialization on the work of UTBK with math magic techniques in SMAN 1 and SMAN 2 Kefamenanu. Furthermore, the background of this socialization is to improve the students' reasoning ability through familiarizing themselves with students solving non-routine problems found during the implementation of UTBK, especially in mathematics. This community service was carried out from January to March 2020 with 40 participants. This activity consists of three stages starting with the assessment of the field, the implementation phase and finally the evaluation phase. In the field assessment stage, the servant determines the participants of the socialization, which is specifically for high school students of class xii, prepares administration, prepares materials and UTBK questions and then prepares a schedule. The second stage is the implementation phase in the form of a brief exposure to the UTBK, then giving samples of the UTBK questions for students to work on and scribing questions. The last stage is the evaluation stage in the form of an evaluation of the implementation of activities that have been arranged based on each task that has been given. Based on the socialization activities that have been carried out it can be concluded that these training activities increase students' knowledge about UTBK and add student skills in working on math UTBK questions . In addition, this training motivates students to be more active in learning mathematics and to be more mature in preparing for the upcoming UTBK.
