Abstract

Kemampuan mengenali bentuk geometri merupakan fondasi krusial perkembangan kognitif anak usia dini. Observasi di KB Al-Ikhlas Pakenjeng menunjukkan kemampuan tersebut belum optimal akibat minimnya media pembelajaran inovatif. Penelitian ini bertujuan mengatasi kendala tersebut melalui pengembangan puzzle berbasis Tangram, serta mengevaluasi kelayakan dan efektivitasnya bagi anak usia 5–6 tahun. Metode yang digunakan adalah Research and Development (R&D) dengan model ADDIE. Hasil penelitian mengidentifikasi kendala operasional berupa kelemahan teknis material dan hambatan kognitif, yakni cognitive overload pada anak saat melakukan rotasi mental objek kompleks yang memicu frustrasi. Sebagai solusi, dilakukan tindakan korektif berupa laminasi glossy, penyesuaian ukuran kepingan, serta penerapan gradasi warna sebagai scaffolding visual untuk membantu anak belajar secara bertahap sesuai teori pendukung. Setelah revisi, media memperoleh skor kelayakan 3,45 (sangat layak). Peningkatan kemampuan anak terbukti signifikan, dari 1,80 menjadi 2,80 pada uji coba terbatas, dan dari 2,00 menjadi 3,50 pada uji coba skala luas, dengan nilai N-Gain 0,71 (kategori tinggi). Dengan demikian, puzzle Tangram terbukti layak dan efektif dalam mendukung pengenalan bentuk geometri serta mampu memitigasi hambatan kognitif melalui desain instruksional yang adaptif.

Abstract

The ability to recognize vowels is an important component of early childhood literacy development. To support the development of this skill, digital flashcards incorporating PowerPoint hyperlinks were used to make learning more engaging and interactive. This study aimed to describe the development process of the digital flashcards, evaluate their feasibility, and assess their effectiveness in improving children's vowel recognition skills. The study employed a Research and Development (R&D) approach based on a modified seven-step Borg and Gall development model. The participants were 14 children, comprising nine boys and five girls. The research involved limited and extensive field trials. Data were collected through interviews, tests, and observations and analyzed using qualitative and quantitative methods. The development process included needs analysis, media development, expert validation, revision, and product testing. The validation results from subject matter experts, media experts, and practitioners indicated that the digital flashcards met the criteria for the highly valid category. The trial results showed improvements in children's vowel recognition skills, with scores increasing from 46.25% to 76.25% in the limited trial and from 64.25% to 91.08% in the extensive field trial. These findings indicate that the digital flashcards have the potential to improve vowel recognition skills in early childhood .
