Abstract

Abstract: This study aims to analyse the validity, practicality, and effectiveness of Scratch learning multimedia in improving students' mathematical literacy skills. This research method is Research and Development (R&D) with ADDIE development model (Analyze, Design, Development, Implementation, and Evaluation). The sample of this research was VIII C students of SMP Negeri 1 Tegalrejo as many as 32 students. The sampling technique used purposive sampling. The data collection techniques were interviews, questionnaires, observation sheets, and tests. The results showed that Scratch learning multimedia was in the very valid category with the acquisition of 80% material validity and 83.56% media validity. Scratch learning multimedia is classified as a very practical category with a percentage of 81.87% based on student responses and 98.33% teacher responses. In addition, this multimedia is effective for improving mathematical literacy skills as evidenced by the difference in pre-test and post-test scores, with an N-Gain value of 0.43 including the moderate category. It can be concluded that the development of Scratch learning multimedia is valid, practical, and effective to improve students' mathematical literacy skills.         Keywords: mathematical literacy, scratch multimedia, statistics.

Abstract

Tujuan dari penelitian ini adalah untuk mengidentifikasi kemampuan pemahaman konsep matematis siswa SMP Negeri 1 Bandongan pada materi persamaan garis lurus. Metode yang digunakan ialah penelitian deskriptif kualitatif. Subjek penelitian ini adalah siswa-siswi kelas VIII F SMP Negeri 1 Bandongan. Pengumpulan data menggunakan soal tes kemampuan pemecahan masalah dan wawancara. Teknik pengambilan data yang dilakukan yaitu 1) melakukan wawancara dengan guru matematika; 2) memberikan soal tes kemampuan pemahaman konsep matematis kepada siswa; 3) menganalisis kemampuan pemahaman konsep matematis siswa berdasarkan indikator kemampuan pemahaman konsep dan mengklasifikasikannya; 4) mengukur kemampuan pemahaman konsep matematis siswa sesuai dengan kategorinya; dan 5) mengukur kemampuan pemahaman konsep matematis siswa secara keseluruhan. Teknik analisis data yang digunakan yaitu reduksi data, penyajian data, dan penarikan kesimpulan/verifikasi. Hasil penelitian menunjukkan bahwa pemahaman konsep matematis siswa tergolong sangat rendah karena siswa belum mampu memenuhi semua indikator kemampuan pemahaman konsep matematis.
