The primary challenge in educational decision-making lies in the low level of statistical literacy and teachers’ limited skills in data analysis, particularly in utilizing interactive technologies. This is evidenced by the pre-training questionnaire results, where the majority of teachers expressed uncertainty or disagreement regarding their sufficient knowledge of statistical analysis, and most had never used interactive web-based tools for data analysis. This community service program aimed to enhance teachers’ statistical literacy through data analysis training using an interactive website based on R-Shiny. The activity was conducted on August 13, 2025, involving high school mathematics teachers in Sukabumi Regency, in collaboration with the Mathematics Teachers’ Working Group (MGMP) as a strategic partner. The training materials covered descriptive statistics, inferential statistics, hypothesis testing, and regression analysis. Post-training evaluation results indicated an improvement in both knowledge and skills. Specifically, 75% of participants strongly agreed that they gained new knowledge and skills beneficial for data-driven decision-making. In addition, more than 80% of participants reported that the materials were easy to understand, well-structured, relevant to their needs, and that the application/website was user-friendly. In conclusion, the use of interactive technology-based training is effective in improving teachers’ knowledge and competencies, particularly in statistical literacy, while also enhancing motivation and fostering a culture of data-driven decision-making in schools.
Abstrak
Permasalahan utama dalam pengambilan keputusan di bidang pendidikan adalah rendahnya literasi statistik dan keterampilan guru dalam mengolah data, terutama menggunakan teknologi interaktif. Hal ini terlihat dari hasil kuesioner sebelum pelatihan, di mana sebagian besar guru ragu atau tidak setuju bahwa mereka memiliki pengetahuan cukup, dan mayoritas belum pernah menggunakan website interaktif untuk analisis dat. Kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan literasi statistik guru melalui pelatihan analisis data menggunakan website interaktif berbasis R-Shiny. Pelatihan dilaksanakan pada 13 Agustus 2025 dengan peserta guru SMA Matematika di Kabupaten Sukabumi dan melibatkan MGMP Matematika SMA Kabupaten Sukabumi sebagai mitra. Materi yang diberikan mencakup statistik deskriptif, inferensia, uji hipotesis, dan regresi. Hasil evaluasi kuesioner pascapelatihan menunjukkan adanya peningkatan pengetahuan dan keterampilan, dimana 75% peserta menyatakan bahwa mereka sangat setuju memperoleh pengetahuan dan keterampilan baru yang bermanfaat untuk pengambilan keputusan berbasis data. Selain itu lebih dari 80% peserta menyatakan materi mudah dipahami, sistematis, sesuai kebutuhan, serta aplikasi/website mudah digunakan. Simpulan kegiatan ini adalah bahwa pelatihan berbasis teknologi interaktif efektif meningkatkan pengetahuan dan kompetensi guru khususnya literasi statistik, memperkuat motivasi, dan mendorong terbentuknya budaya pengambilan keputusan berbasis data di sekolah.
