Implementation of Discovery Learning Model in Social Arithmetic Learning for Middle School Students

Abstract

This study aims to analyze the effect of the discovery learning model on student learning outcomes in social arithmetic material. This research is a quasi-experiment with a nonequivalent posttest-only control group design. The population of this study was seventh-grade students of SMP Negeri 6 Bengkulu City. The sample was selected using the purposive sampling technique, namely class VIID as the experimental class with 20 students and class VIIC as the control class with as many as 23 people. Data was collected by using a social arithmetic material test. The data were analyzed descriptively and statistically by using an independent t-test. The results showed an effect of the discovery learning model on improving student learning outcomes in social arithmetic material. Statistically descriptive, the average student learning outcomes using the discovery learning model are higher than in conventional learning classes. Keywords: discovery learning, quasi experiment, learning outcomes. Abstrak: Penelitian ini bertujuan untuk menganalisis pengaruh model discovery learning terhadap hasil belajar siswa materi aritmetika sosial. Penelitian ini merupakan eksperimen semu denga desain nonequivalent posttest-only control group. Populasi penelitian ini adalah siswa kelas VII SMP Negeri 6 Kota Bengkulu. Sampel yang dipilih dengan menggunakan teknik purvosif sampling yaitu siswa kelas VIID sebagai kelas eksperimen dengan jumlah siswa sebanyak 20 orang dan kelas VIIC sebagai kelas kontrol sebanyak 23 orang. Pengumpulan data dilakukan dengan tes materi aritmatika sosial. Data dianalisis secara deskriptif dan statistik infransial menggunakan uji t independent. Hasil penelitian menunjukkan bahwa terdapat pengaruh model discovery learning terhadap peningkatan hasil belajar siswa materi aritmatika sosial. Secara statistik deskriptif rata-rata hasil belajar siswa menggunakan model discovery learning lebih tinggi dibandingkan kelas pembelajaran konvensional. Kata kunci: discovery learning, eksperimen semu, hasil belajar. DOI: http://dx.doi.org/10.23960/jpmipa/v23i3.pp1006-1016
