Abstract

This study is motivated by Indonesia's low results in PISA, supported by the findings of previous studies which show that students still face difficulties in solving PISA questions, especially on the content of change and relationship level 3 and above. In addition, the results of observations by researchers show that students have difficulty in understanding algebraic story problems, especially in converting problems into mathematical models. The purpose of this research is to produce mathematical problems of PISA model level 3 and 4 on the content of change and relationship for junior high school students that are valid, practical, and have potential effects. This research uses the Research and Development (R&D) research type with the ADDIE development model. The results of this study are question instruments have received very valid criteria with a percentage of 90.8% based on validation tests by experts. This question instrument has also received a practical category with a percentage of 95.9% based on the small group test, so that the question is suitable for field testing. In the field test, to assess the potential effect, the average student score was 85.52 which has a very good category, with 79% of students successfully getting a very good score category. Based on the results of this study, it can be concluded that the questions developed by researchers are valid, practical, and have potential effects, so they are suitable for use. Keywords: change and relationship content; PISA; research and development AbstrakPenelitian ini dilatarbelakangi oleh rendahnya hasil Indonesia dalam PISA, didukung oleh temuan penelitian sebelumnya yang menunjukkan bahwa siswa masih menghadapi kesulitan dalam menyelesaikan soal PISA, terutama pada konten change and relationship level 3 keatas. Selain itu, hasil observasi oleh peneliti menunjukkan bahwa siswa mengalami kesulitan dalam memahami soal cerita aljabar, khususnya dalam mengubah masalah ke dalam model matematika. Tujuan dari penelitian ini adalah untuk menghasilkan soal matematika model PISA level 3 dan 4 pada konten change and relationship untuk siswa SMP yang valid, praktis, dan memiliki efek potensial. Penelitian ini menggunakan jenis penelitian Research and Development (R&D) dengan model pengembangan ADDIE. Hasil penelitian ini adalah instrumen soal telah mendapat kriteria sangat valid dengan persentase 90,8% berdasarkan uji validasi oleh ahli. Instrumen soal ini juga telah mendapat kategori praktis dengan persentase 95,9% berdasarkan uji kelompok kecil, sehingga soal tersebut layak untuk diuji coba di lapangan. Dalam uji lapangan, untuk menilai efek potensial, rata-rata nilai siswa adalah 85,52 yang memiliki kategori sangat baik, dengan 79% siswa berhasil mendapatkan kategori nilai sangat baik. Berdasarkan hasil penelitian ini, dapat disimpulkan bahwa soal yang dikembangkan oleh peneliti adalah valid, praktis, dan memiliki efek potensial, sehingga layak digunakan. Kata Kunci: konten change and relationship; penelitian pengembangan; PISA  DOI: http://dx.doi.org/10.23960/mtk/v12i2.pp111-122

Abstract

This study originaled from students problems who identificated a learning loss during Pandemic COVID-19. Starting that problem there is a need for a learning media that can be used by students to reduce the danger of learning loss. This research was conducted with R&D approach (Research and Development), which produces a learning media by adapting the method of ADDIE.. The purpose of this research is to create an android application-based learning media, namely Geometry of Mathematics (GEOMATHICS) to overcome Learning Loss with the gamification method. The results obtained from the validation indicate that the GEOMATHICS application has met the eligibility criteria for learning media obtained from the validation results with the results of the assessment being 80% from material experts, 90% from media experts and 94% from practicing experts. With the results obtained the average assessment of learning media is 88%, which is included in the very good category and does not need to be revised. Therefore, the results of data analysis obtained have answered the problem formulation, namely the GEOMATHICS application has met the eligibility criteria to be applied in the learning process at SMP Plus Rahmat Kediri.
