Abstract

ABSTRAK Penelitian ini bertujuan untuk  menjelaskan pengaruh penerapan model pembelajaran berbasis Problem Based Learning terhadap hasil belajar siswa. Jenis penelitian yang digunakan adalah penelitian eksperimen (quasi experiment design). Pengambilan sampel berdasarkan teknik sampling purposive yang diperoleh siswa kelas X MIPA 1 ( N = 30) sebagai kelas eksperimen yang menerapkan pembelajaran dengan model Problem Based Learning dan siswa kelas X MIPA 3 (N = 30) sebagai kelas kontrol yang menerapkan pembelajaran konvesional. Teknik pengumpulan data men ggunakan tes untuk hasil belajar. Berdasarkan hasil analisis Uji-t dua sampel independen melalui nilai rata-rata posttest hasil belajar yaitu thitung > ttabel (1,96 > 1,71). Disimpulkan bahwa terdapat pengaruh pembelajaran menggunakan model Problem Based Learning terhadap hasil belajar. Kata kunci: Model Problem Based Learning, Hasil Belajar ABSTRACT This research aimed to explain the effect of applying based learning models Problem Based Learning to student learning outcomes. The type of research was experimental research (quasi experiment design). The sampling was based on purposive sampling technique obtained by students of class X MIPA 1 (N = 30) as an experimental class that applied learning with the model Problem Based Learning and students of class X MIPA 3 (N = 30) as a control class that applied conventional learning. Data collection techniques used tests for learning outcomes. Based on the results of the t-test analysis of two independent samples through the average value of posttest learning outcomes, namely tcount > ttable (1.96> 1.71), it was concluded that there was an effect of learning using the model Problem Based Learning of learning outcomes. Keywords: Problem Based Learning Model, Learning Outcomes

Abstract

ABSTRAK Penelitian ini bertujuan untuk mengetahui apakah terdapat pengaruh pemahaman konsep dan hasil belajar pada konsep momentum dan impuls antara siswa yang diajar dengan model Quantum Learning dan siswa yang diajarkan dengan model Direct Instruction. Penelitian ini merupakan penelitian kuasi eksperimen. Sampel penelitian ini diambil dengan teknik purposive sampling, kelas X MIPA 2 sebagai kelas eksperimen dan kelas X MIPA 3 sebagai kelas kontrol. Pengambilan data penelitian dengan menggunakan tes pemahaman konsep dan hasil belajar berupa soal uraian pada konsep momentum dan impuls. Analisis data menggunakan Uji-t. Hasil penelitian menunjukkan bahwa pemahaman konsep dengan model Quantum Learning dengan rata-rata 80,45 lebih tinggi dibandingkan dengan siswa yang mengikuti pembelajaran dengan model pembelajaran Direct Instruction dengan rata-rata 60,12 dan t hitung pemahaman konsep 9,71 yang lebih besar dari t tabel yaitu 1,67155 dan hasil belajar dengan model Quantum Learning menggunakan nilai rata-ratanya 80,61 lebih tinggi dibandingkan dengan kelas kontrol dengan rata-rata 57,29 dengan t hitung  hasil belajar 8.68 yang lebih besar dari t tabel pada taraf kepercayaan 95%. Hasil penelitian menunjukkan bahwa terdapat perbedaan pemahaman konsep dan hasil belajar model Quantum Learning dengan model Direct Instruction sehingga dapat disimpulkan terdapat pengaruh model Quantum Learning terhadap pemahaman konsep dan hasil belajar siswa kelas X. Kata Kunci: Quantum Learning, Pemahaman Konsep, Hasil Belajar ABSTRACT This research was to determine if there is or not an effect of understanding concepts and learning outcomes on the concepts of momentum and impulses between students taught with Quantum Learning Model and students taught with the Direct Instruction Model. This research was a quasi-experimental. The research sample was taken by purposive sampling technique, class of X MIPA 2 as the experimental class and class of X MIPA 3 as the control class. Retrieval of research data used tests of understanding concepts and learning outcomes in the form of questions describing the concepts of momentum and impulses. Data analysis used t-test. The results showed that understanding the concept with the Quantum Learning Model with an average of 80.45 was higher than that of students who took part in the Direct Instruction Model with an average of 60.12 and t calculated the understanding of the concept of 9.71 which was greater than ttable namely 1.67155 and learning outcomes with the Quantum Learning Model with an average value of 80.61 higher than the control class with an average of 57.29. Value of tcalculated of learning outcomes was 8.68 which greater than ttable at the confidence level of 95%. The results showed that there were differences in the understanding of the concepts and learning outcomes of the Quantum Learning model and the Direct Instruction model which meant that there was an effect of Quantum Learning Model on understanding of concepts and learning outcomes of tenth grade students. Keywords: Quantum Learning, Understanding of Concepts, Learning Outcomes
