PENGARUH MODEL PEMBELAJARAN KONTEKSTUAL PADA POKOK BAHASAN HIDROKARBON TERHADAP HASIL BELAJAR KIMIA

Abstract

ABSTRAK

Penelitian ini bertujuan mendeskripsikan pengaruh model pembelajaran kontekstual pada pokok bahasan hidrokarbon terhadap hasil belajar kimia siswa. Penelitian ini merupakan  eksperimen semu dengan rancangan nonequivalent pre-test post-test control group design. Populasi penelitian ini adalah seluruh siswa kelas XI MIPA SMA Negeri 1 Penebel tahun ajaran 2018/2019. Sampel penelitian ini adalah siswa kelas XI MIPA 1 sebagai kelas eksperimendan siswa kelas XI MIPA 2 sebagai kelas kontrol yang dipilih dengan teknik cluster random sampling. Siswa di kelas eksperimen dibelajarkan dengan model pembelajaran kontekstual dan siswa di kelas kontrol dibelajarkan dengan model pembelajaran discovery. Data hasil belajar kimia siswa dikumpulkan dengan cara testing menggunakan tes hasil belajar. Data dianalisis dengan teknik analisis deskriptif dan inferensial. Analisis deskriptif hasil belajar kimia siswa dideskripsikan berupa skor rata-rata pre-test dan post-test siswa. Analisis inferensial hasil belajar kimia siswa menggunakan analisis kovarian (Anakova) dengan taraf signifikansi 0.05 dan uji dilakukan dengan bantuan SPSS 16 for windows. Hasil analisis menunjukkan terdapat pengaruh signifikan model pembelajaran kontekstual terhadap hasil belajar kimia siswa. Skor rata-rata hasil belajar siswa di kelas eksperimen (73.42) lebih tinggi dibandingkan dengan kelas kontrol (64.26).

Katakunci: model pembelajaran kontekstual, model pembelajaran discovery, hasil belajar kimia

ABSTRACT

This reseach aim to describe the influence of the contextual learning model to chemistry student’s achievement. It is a quasi-experiment reseach with nonequivalent pre-test post-test control group design. The population was the eleventh-grade student’s of SMA Negeri 1 Penebelon academic year 2018/2019. The samples werethe students of XI MIPA 1 class as experimental class and the students of XI MIPA 2 class as control class that selected with cluster random sampling technique. The students in the experimental class learned through the contextual learning model and the ones in the control class learned through the discovery learning model. The data on the chemistry student’s achievement were collected through the test of the achievement test. The data were analyzed through descriptive and inferential analysis. Descriptive analysisof chemistry student’s achievement were described in the form of the mean score of student’s pre-test and post-test. Inferential analysis of chemistry student’s achievement were used covarian analysis (Anacova) with 0.05 significance level and it was performed by the assist of SPSS 16 for windows. The results showed that there were the significant effect of contextual learning model to the chemistry student’s achievement. The mean score of student’s achievement in experimental class (73.42) was higher than control class (64.26).

Keywords: contextual learning model, discovery learning model, chemistry student’s achievement
