Efektivitas Pembelajaran Realistic Mathematics Education (Rme) Berbantuan Video Pembelajaran Bernuansa Etnomatematika Terhadap Kemampuan Pemahaman Konsep Matematis Siswa

Abstract

Abstrak

Proses pembelajaran matematika yang menggunakan model pembelajaran langsung dapat menyebabkan rendahnya pemahaman konsep matematis siswa dan kurang aktifnya siswa dalam belajar. Hal ini dibuktikan dengan hasil studi pendahuluan yang menunjukkan bahwa siswa yang tuntas hanya sebesar 13%. Tujuan penelitian ini yaitu mengkaji efektivitas pembelajaran RME berbantuan video pembelajaran bernuansa etnomatematika terhadap kemampuan pemahaman konsep matematis siswa. Populasi penelitian ini adalah seluruh siswa kelas VIII SMP 3 Bae tahun pelajaran 2021/2022. Sampel penelitian ini adalah siswa kelas VIII F dan VIII G yang dipilih dengan teknik purposive sampling. Data penelitian diperoleh  dari hasil pretest dan posttest. Analisis data penelitian ini menggunakan uji normalitas, uji homogenitas, uji independent sample t-test, uji N-Gain, dan uji proporsi. Hasil penelitian ini menunjukkan bahwa rata-rata pemahaman konsep matematis siswa yang mengikuti pembelajaran RME berbantuan video pembelajaran bernuansa etnomatematika lebih tinggi daripada pemahaman konsep matematis siswa yang mengikuti pembelajaran langsung, rata-rata peningkatan pemahaman konsep matematis siswa yang mengikuti pembelajaran RME berbantuan video pembelajaran bernuansa etnomatematika sebesar 0.73, serta proporsi siswa yang tuntas mencapai 83% banyaknya siswa yang mengikuti pembelajaran RME berbantuan video pembelajaran bernuansa etnomatematika. Berdasarkan hasil dan pembahasan, diperoleh kesimpulan bahwa pembelajaran RME efektif terhadap pemahaman konsep matematis siswa.

Abstract

The process of learning mathematics that uses a direct learning model can cause students' low understanding of mathematical concepts and students' lack of active learning. This is evidenced by the results of a preliminary study which shows that only 13% of students complete. The purpose of this study is to examine the effectiveness of RME learning assisted by ethnomathematical learning videos on the ability to understand students' mathematical concepts. The population of this research is all eighth grade students of SMP 3 Bae for the academic year 2021/2022. The samples of this study were students of class VIII F and VIII G who were selected by purposive sampling technique. Research data obtained from the results of the pretest and posttest. The data analysis of this research used normality test, homogeneity test, independent sample t-test, N-Gain test, and proportion test. The results of this study indicate that the average understanding of mathematical concepts of students who participate in RME learning assisted by ethnomathematical learning videos is higher than the understanding of mathematical concepts of students who participate in direct learning, the average increase in understanding of mathematical concepts of students who participate in RME learning assisted by ethnomathematical learning videos. amounted to 0.73, and the proportion of students who completed reached 83% of the number of students who participated in RME learning assisted by ethnomathematical learning videos. Based on the results and discussion, it was concluded that RME learning was effective in understanding students' mathematical concepts.
