Abstract

This study aims to investigate how WhatsApp has been used to deliver mathematics lessons in Indonesia across multiple educational levels, with a particular focus on junior high schools, within the last four  years. The objective is to identify the extent, practices, and effectiveness of WhatsApp as either a primary or supplementary instructional tool in mathematics teaching at the elementary, junior high, senior high, and tertiary levels. The research method employed was a systematic literature review of Scopus-indexed journal articles published in English between 2019 and 2024. Relevant studies were selected, analyzed, and synthesized according to their research design, educational level, and findings. Both qualitative and quantitative research were included to provide a comprehensive understanding of how WhatsApp has been integrated into mathematics education. In many cases, WhatsApp is integrated into instructional designs such as blended learning, flipped classroom activities, and collaborative problem solving, allowing students to interact with teachers and peers. The results show that WhatsApp is widely adopted by Indonesian teachers, particularly during and after the pandemic, to facilitate communication, share learning materials, and support problem-solving activities. At the elementary and junior high levels, studies report that WhatsApp helps improve students’ motivation and engagement, though the impact on learning outcomes is mixed. At the senior high and vocational levels, WhatsApp is often combined with other digital platforms such as YouTube to support blended learning. Evidence from higher education remains limited, with indications that WhatsApp serves mainly as a communication channel rather than a structured learning platform. In conclusion, WhatsApp is a practical, low-cost, and accessible tool that supports mathematics instruction in Indonesia. However, its effectiveness depends on instructional design, teacher facilitation, and integration with other pedagogical strategies

Abstract

Based on the 2018 PISA results, Indonesian students' numeracy skills remain low, with the majority not reaching the basic proficiency level. One innovative approach is STEM design-based learning, which integrates aspects of Science, Technology, Engineering, and Mathematics into the learning process. While STEM has often been implemented in schools, its application in higher education remains limited. This study aims to analyze the effectiveness of the STEM design-based learning in enhancing the numeracy skill of pre-service teachers. The research population comprised sixth-semester students of the Mathematics Education undergraduate program at Universitas Negeri Jakarta, with a sample of 25 students. Data were collected through numeracy tests administered before (pre-test) and after (post-test) the implementation of the STEM design-based learning. Data analysis using a t-test, t(25) = 6.3189 with a p-value = 7.818 × 10⁻⁷ (p < 0.05), indicating that the null hypothesis (H₀) is rejected and the alternative hypothesis (H₁) is accepted, it means that the post-test scores were significantly higher than the pre-test scores. Then, the Cohen’s d-value was 1.26, indicating that the treatment had a very large effect on improving the numeracy skill of the pre-service teachers.

Abstract

Keterbatasan pemanfaatan perangkat lunak statistik berbasis coding menjadi salah satu kendala dalam meningkatkan literasi statistik dan kompetensi digital guru dalam pengolahan serta analisis data. Guru umumnya masih menggunakan perangkat lunak statistik berbasis menu, sehingga diperlukan pengenalan alternatif perangkat lunak yang mendukung pengolahan data secara lebih fleksibel dan sistematis. Kegiatan Pengabdian kepada Masyarakat (P2M) ini bertujuan untuk meningkatkan pengetahuan dan keterampilan guru SMP di Depok dalam menggunakan Program R untuk pengolahan dan analisis data. Solusi yang ditawarkan berupa pelatihan yang dilaksanakan melalui penyampaian materi, praktik langsung, dan pendampingan penggunaan Program R. Evaluasi keberhasilan kegiatan dilakukan melalui pengukuran kemampuan peserta sebelum dan setelah pelatihan menggunakan pretest dan posttest. Hasil evaluasi menunjukkan adanya peningkatan rata-rata kemampuan peserta setelah mengikuti pelatihan, dengan rata-rata nilai posttest lebih tinggi 7 poin dibandingkan dengan pretest. Hasil Paired - menunjukkan nilai - sebesar 0,003 < 0,05, yang mengindikasikan adanya perbedaan yang signifikan antara kemampuan peserta sebelum dan setelah mengikuti pelatihan. Dengan demikian, pelatihan Program R dapat menjadi salah satu alternatif untuk meningkatkan literasi statistik dan kompetensi digital guru dalam pengolahan dan analisis data berbasis coding.

Abstract

Penelitian ini bertujuan untuk melihat pengaruh penggunaan model pembelajaran CTL yang dipadukan dengan Kahoot terhadap kemampuan literasi numerasi peserta didik. Penelitian ini menggunakan metode eksperimen semu dengan desain posttest only control group, serta cluster random sampling untuk pengambilan sampel. Instrumen penelitian terdiri dari lima soal uraian yang sudah terbukti valid dengan skor uji validitas yaitu  serta reliabel dengan koefisien reliabilitas yaitu , diaplikasikan untuk melihat kemampuan literasi numerasi peserta didik pada materi statistika. Hasil uji-t menunjukkan bahwa nilai  yaitu  pada tingkat signifikansi 5%, dengan rata-rata skor literasi numerasi pada kelas eksperimen lebih tinggi dibandingkan kelas kontrol. Uji Cohen’s d effect size menghasilkan nilai  termasuk kategori large dengan persentase sebesar 79%. Dengan demikian, dapat disimpulkan bahwa dengan menggunakan model CTL yang dipadukan dengan Kahoot memberikan pengaruh yang baik terhadap kemampuan literasi numerasi peserta didik di SMP Negeri 19 Jakarta.
