Abstract

Numeracy skills can be supported by the use of digital teaching materials. One of them is digital teaching materials designed to support thinking skills to improve concentration and problem solving, with interesting features such as videos, images, and texts by only utilizing links and tools available on students' Android mobile phones. This study aims to produce valid and practical digital teaching materials and describe students' responses after using the game. The subjects of this study were 24 students of grade VII of SMP Negeri 4 Jirak Jaya. This research procedure uses a research design based on the Plomp development model. The Plomp development procedure consists of 4 phases, namely preliminary study, design phase, realization phase, and test, evaluation and revision phases. Data collection techniques used are questionnaires, observations, documentation, and interviews. Questionnaires are used to assess the validity and practicality of teaching materials. Observations are used to measure the effectiveness of learning. The data analysis technique used in this study is descriptive, both quantitative descriptive and qualitative descriptive. Based on the results of data analysis, it was obtained that the developed digital teaching materials fall into the valid category when viewed from the aspects of content, construction, language, and ICT. In addition, numeracy-based digital teaching materials also fall into the practical category when viewed from the aspects of ease of use, attractiveness, challenges, and their application in mathematics learning.

Abstract

Students' numeracy skills remain low, and some digital teaching materials are designed to support concentration and problem-solving through interactive features. In fact, students' Android devices have yet to be fully optimized for learning. This study aims to produce valid and practical digital teaching materials and to describe student responses after their use. The research followed the Plomp development model, consisting of four phases: preliminary investigation, design, realization, and test, evaluation, and revision. The subjects were 20 seventh-grade students from SMP Negeri 4 Jirak Jaya. Data were collected through questionnaires, observations, documentation, and interviews, and analyzed using descriptive quantitative and qualitative methods. The results show that the material is valid in terms of content, construction, language, and ICT, and is practical for use. Students' numeracy also improved to a good category. The digital material has potential effects on numeracy and is recommended for classroom use. Abstrak Kemampuan numerasi siswa masih rendah, dan beberapa materi pembelajaran digital dirancang untuk mendukung konsentrasi dan pemecahan masalah melalui fitur interaktif. Faktanya, perangkat Android siswa belum sepenuhnya dioptimalkan untuk pembelajaran. Studi ini bertujuan untuk menghasilkan materi pembelajaran digital yang valid dan praktis serta mendeskripsikan respons siswa setelah penggunaannya. Penelitian ini mengikuti model pengembangan Plomp, yang terdiri dari empat fase: preliminary investigation, design, realization, and test, evaluation, dan revision. Subjek penelitian adalah 20 siswa kelas tujuh dari SMP Negeri 4 Jirak Jaya. Data dikumpulkan melalui kuesioner, observasi, dokumentasi, dan wawancara, dan dianalisis menggunakan metode kuantitatif dan kualitatif deskriptif. Hasil penelitian menunjukkan bahwa materi tersebut valid dari segi isi, konstruksi, bahasa, dan TIK, serta praktis untuk digunakan. Kemampuan numerasi siswa juga meningkat ke kategori baik. Materi digital tersebut memiliki potensi pengaruh terhadap kemampuan numerasi dan direkomendasikan untuk digunakan di kelas.
