Abstract

Abstrak

Penelitian ini bertujuan untuk: (1) menghasilkan media pembelajaran matematika “PAKADES: Papan Flanel Perkalian Desimal” yang layak digunakan untuk pembelajaran perkalian desimal di SD dan (2) mengetahui keefektifan media pembelajaran matematika “PAKADES” terhadap hasil belajar siswa pada materi perkalian desimal di SD.Penelitian ini merupakan penelitian pengembangan dengan 7 langkah berupa penentuan masalah, studi literatur, perancangan produk, validasi desain/uji coba internal, revisi desain, pembuatan produk, dan uji coba terbatas. Penentuan masalah dilakukan di SD Negeri Percobaan 4 Wates.Pada studi literatur didapatkan 30 referensi buku dan jurnal. Perancangan produk menghasilkan desain/prototype “PAKADES”.Validasi desain/uji coba internal dilakukan oleh 1 ahli materi, 1 ahli media, dan 1 praktisi. Revisi desain dan pembuatan produk menghasilkan media pembelajaran matematika “PAKADES”. Uji keefektifan melalui eksperimen one-group pretest-posttest design dengan mengambil satu kelompok yang terdiri dari 20 siswa kelas VB SD Negeri Percobaan 4 Wates. Pengumpulan data menggunakan angket dan tes.Analisis data dengan teknik analisis kuantitatif deskriptif.Hasil penelitian menunjukkan bahwa: (1) kelayakan media pembelajaran  “PAKADES” menurut ahli materi mendapatkan skor rata-rata 4,88 yang termasuk dalam kategori sangat baik, (2) kelayakan media pembelajaran “PAKADES” menurut ahli media mendapatkan skor rata-rata 3,96 yang termasuk dalam kategori baik, (3) kelayakan media pembelajaran “PAKADES” menurut guru mendapatkan skor rata-rata 4,82 yang termasuk dalam kategori sangat baik, (4) media pembelajaran “PAKADES” efektif meningkatkan nilai rata-rata siswa sebesar 148%.

Abstract

This research is aimed to: (1) develop “PAKADES: Papan Flanel Perkalian Desimal” that valid to be used in decimal multiplication learning in elementary school and (2) knowthe effectiveness of “PAKADES” learning media toward students’ score in decimal multiplication in elementary school.This research was a research and development with 7 steps such as problem collecting, study of literature, product designing, design validation/internal testing, revision of design, production, and preliminary field testing. Problem collecting was done in Percobaan 4 Wates Elementary School. From study of literature step, 30 books and journals reference were collected. Product designing resulted design/prototype of “PAKADES”. Design validation/internal testing were done by 1 content expert, 1 media expert, and 1 practitioner. Revision of design and production resulted “PAKADES” learning media. Effectivity testing was done through one group pretest-posttest experiment for 1 group consist of 20 students of Percobaan 4 Wates Elementary School grade VB. Data collection used questionnaire and test. Data analysis used descriptive quantitative technique.The result of this research showed that: (1) the validity of “PAKADES” learning media according to content expert reached 4,88 in its mean score and was included as very good category, (2) the validity of “PAKADES” learning media according to media expert reached 3,96 in its mean score and included as good category, (3) the validity of “PAKADES” learning media according to teacher reached 4,82 in its mean score and included as very good category, (4) “PAKADES” learning media was effective to improve students’ average score by 148%.
