Abstract

ABSTRACT. This research was conducted to describe the students learning outcomes who were taught using the Blended Learning model and face to face methods on the relations and functions lesson. The research was conducted at SMP Frater Don Bosco in the odd semester of the 2019/2020 academic year. The research subjects were students of class VIII A as an experimental class taught using the Blended Learning model and students of class VIII B as a control class taught using the face to face method. Data collection in this research used test and data analysis used t-test of differences mean of the two groups. The research result, shows that the average student learning outcomes taught using the Blended Learning model were higher than the average learning outcomes of students who are taught using face-to-face methods on the material relations and functions. Keywords: Blended Learning, Face to Face, Relationships and Functions

Abstract

Penelitian ini dilatarbelakangi permasalahan yang ditemui dalam pembelajaran matematika di SMPN 2 Tondano, berupa hasil belajar siswa yang belum optimal dan kendala-kendala pelaksanaan pembelajaran di masa pandemic Covid-19.  Tujuan penelitian ini adalah untuk mengkaji hasil belajar siswa dalam pembelajaran persamaan garis lurus dengan model pembelajaran Direct Instruction berbantuan Geo-Gebra via aplikasi zoom meeting. Rancangan yang digunakan pada kuasi-eksperimen ini yakni pretest-posttest-control-group design, dimana banyaknya siswa pada kelas eksperimen 22 orang dan pada kelas kontrol sebanyak 22 siswa. Hasil analisis uji-t menunjukkan bahwa t-hitung lebih dari t-tabel, sehingga disimpulkan pada taraf nyata 5 %, bahwa rata-rata hasil belajar siswa pada kelas dengan model pembelajaran langsung berbantuan GeoGebra via Aplikasi Zoom lebih dari rata-rata hasil belajar siswa yang belajar dengan model pembelajaran Direct Instruction.
