Mahasiswa UNNES Kembangkan DENOMATH, Perkuat Literasi Statistik melalui Pembelajaran Digital

Mahasiswa Universitas Negeri Semarang (UNNES) mengembangkan DENOMATH (Redenomination Mathematics), sebuah website pembelajaran digital yang mengintegrasikan konteks redenominasi mata uang dengan model Challenge-Based Learning dan prinsip Deep Learning. Inovasi ini dikembangkan untuk meningkatkan kemampuan literasi statistik sekaligus menanamkan karakter literasi keuangan pada murid sekolah menengah pertama.

DENOMATH dikembangkan oleh tim mahasiswa yang terdiri atas Maulana Nur Sa’bani, Salsabila Afifah, Nashwa Aina Salsabila, dan Putri Nawwalin Nikmah, di bawah bimbingan Adi Satrio Ardiansyah dari UNNES.

Pengembangan inovasi ini berangkat dari hasil studi pendahuluan pada murid kelas VII yang menunjukkan rata-rata kemampuan literasi statistik sebesar 49,56. Hasil tersebut menunjukkan perlunya media pembelajaran yang tidak hanya membantu murid memahami konsep matematika, tetapi juga melatih kemampuan menginterpretasikan dan menggunakan informasi statistik dalam kehidupan sehari-hari. Penguatan literasi keuangan sejak usia sekolah juga menjadi salah satu dasar pengembangan DENOMATH.

DENOMATH dirancang sebagai platform pembelajaran interaktif pada materi penyajian data dengan mengangkat tema redenominasi. Melalui konteks tersebut, murid diajak memahami penyederhanaan nominal mata uang, mengolah informasi numerik, menyajikan data dalam bentuk diagram, serta menarik kesimpulan berdasarkan informasi yang diperoleh.

Dalam penggunaannya, DENOMATH mengintegrasikan model Challenge-Based Learning dengan prinsip pembelajaran mendalam (Deep Learning), yaitu meaningful, mindful, dan joyful learning. Pendekatan ini mendorong murid untuk mengenali permasalahan, mengajukan pertanyaan, melakukan penyelidikan, mengolah informasi, hingga menyusun dan mengomunikasikan solusi.

Untuk mendukung proses pembelajaran, DENOMATH dilengkapi sejumlah fitur interaktif. Fitur tersebut meliputi Ayo Belajar untuk mengeksplorasi materi, kalkulator redenominasi, pembuat diagram otomatis, evaluasi interaktif dengan umpan balik otomatis, serta Tanya AI yang menyediakan layanan chatbot dan percakapan suara. Selain itu, tersedia fitur learning analytics yang memungkinkan guru memantau aktivitas dan perkembangan hasil belajar murid secara real-time.

Website ini dikembangkan menggunakan model ADDIE yang mencakup lima tahapan, yaitu Analysis, Design, Development, Implementation, dan Evaluation. DENOMATH dapat diakses melalui perangkat komputer maupun telepon genggam pada laman https://denomath.com.

Implementasi DENOMATH telah dilaksanakan di tujuh satuan pendidikan, yaitu SMP Negeri 1 Mejobo, SMP Negeri 4 Bae, MTs Al Asror, SMP Negeri 3 Gebog, SMP Negeri 1 Ungaran, SMP Negeri 12 Semarang, dan Sekolah Indonesia Kuala Lumpur (SIKL). Kegiatan ini melibatkan 219 murid kelas VII.

Hasil implementasi menunjukkan rata-rata nilai posttest murid mencapai 78,29, melampaui Kriteria Ketercapaian Tujuan Pembelajaran (KKTP) sebesar 70. Dari 219 murid yang mengikuti implementasi, sebanyak 187 murid atau 85,39 persen berhasil mencapai kriteria tersebut.

Hasil pengujian statistik juga menunjukkan bahwa rata-rata nilai murid secara signifikan melampaui KKTP. Selain itu, persentase ketuntasan belajar terbukti secara signifikan melampaui target sebesar 70 persen.

Melalui pengembangan dan implementasi DENOMATH, tim berharap website ini dapat terus disempurnakan dan dimanfaatkan secara lebih luas sebagai alternatif media pembelajaran digital. Inovasi ini diharapkan turut mendukung penguatan literasi statistik sekaligus membangun karakter literasi keuangan murid sejak dini.
