Pengaruh Model Problem Based Learning Dengan Media Audio Visual dan Laboratorium Riil Materi Asam Basa Terhadap Hasil Belajar:

The Effect of Problem Based Learning Model using Audio Visual Media and Real Acid Base Material Laboratory on Learning Outcomes

Abstract

Penelitian ini bertujuan untuk mengetahui perbedaan peningkatkan hasil belajar siswa  MAN 1 Stabat melalui penerapan model Problem Based Learning (PBL) berbantuan media audio visual dan laboratorium riil pada pokok bahasan Asam Basa. Metode yang digunakan dalam penelitian ini adalah eksperimen dan pengambilan sampel dilakukan secara random sampling. Hasil penelitian menunjukkan, untuk kelas eksperimen 1 diperoleh nilai rata-rata tes awal sebesar 31,11 dan nilai tes akhir adalah 83,94, sementara untuk kelas eksperimen 2 diperoleh hasil nilai rata-rata tes awal adalah 32,66 dan nilai tes akhir adalah 79,60. Hasil uji normalitas dan homogenitas tes awal dan akhir menunjukkan data kedua kelas berdistribusi normal dan homogen. Hasil uji t pihak kanan diperoleh t_hitung = 2,36 dan t_tabel = 1,9994, sehingga t_hitung>t_tabel yang berarti Ha diterima. Berdasarkan data tersebut, dapat disimpulkan bahwa adanya peningkatan hasil belajar siswa MAN 1 Stabat melalui model Problem Based Learning (PBL) berbantuan media audio visual dibandingkan hasil belajar siswa melalui model Problem Based Learning (PBL) berbantuan laboratorium riiil  pada pokok bahasan Asam Basa.

This study aims to determine the differences in improving student learning outcomes of MAN 1 Stabat who use the application of the Problem Based Learning (PBL) model assisted by real audio-visual and laboratory media on the subject of Base Acid. The method used in this study is an experimental method. Sampling is done by random sampling. The results showed that for the experimental class 1, the average pretest score was 31.11 and the post-test value was 83.94, while for the experimental class 2 the results of the pretest average were 32.66, and the post-test score was 79.60. The results of the normality and homogeneity test from the pretest and posttest showed that the data of the two classes were normally distributed and homogeneous. The results of the t-test are tcount = 2.36 and ttable = 1.9994 so that tcount> ttabel which means Ha is accepted. Based on these data, it can be concluded that there is an increase in student learning outcomes of MAN 1 Stabat through the Problem Based Learning (PBL) model assisted by audiovisual media compared to the Problem Based Learning (PBL) model assisted by clinical laboratories on the topic of Acid-Base.
