Abstract


Penelitian ini bertujuan untuk mengungkap adanya perbedaan hasil belajar siswa yang diberi pembelajaran MEA dan REACT pada materi reaksi oksidasi reduksi, dan hasil belajar mana yang lebih baik di antara keduanya. Penelitian dilaksanakan di suatu SMA Negeri di Pekalongan tahun ajaran 2013/2014 dengan populasi seluruh siswa kelas X MIPA. Sampel diambil menggunakan teknik cluster random sampling, karena populasi berdistribusi normal dan homogen. Desain penelitian yang digunakan adalah pretest-posttest group design. Pengambilan data dilakukan dengan metode tes, observasi, dan dokumentasi. Hasil analisis data menunjukkan bahwa adanya perbedaan rata-rata nilai post-test antara kelas eksperimen 1 dan kelas eksperimen 2 setelah keduanya diberikan perlakuan yang berbeda pada materi yang sama. Hasil belajar kognitif diperoleh dari pretest dan posttest masing-masing kelas eksperimen. Hasil menunjukkan adanya peningkatan dari skor pretest dan posttest pada kedua kelas eksperimen tersebut dengan nilai rata-rata pretest kelas eksperimen 1 (MEA) 34 meningkat menjadi 74 pada posttest dan kelas eksperimen 2 (REACT) 39 meningkat menjadi 84,97. Berdasarkan hasil penelitian dapat disimpulkan bahwa penerapan pembelajaran MEA dan REACT dapat meningkatkan hasil belajar. Hasil belajar kimia aspek kognitif yang diberi pembelajaran REACT lebih baik dibandingkan yang diberi pembelajaran MEA.

This study aims to reveal the difference in learning outcomes of students who were given learning material MEA and REACT on oxidation-reduction reactions, and which one is better between the two models. The experiment was conducted in a Senior High School in Pekalongan academic year 2013/2014 with the entire population of students of science class grade X. Samples were taken using cluster random sampling technique, because of the normal distribution and homogenous population. Design research is pretest-posttest group design. Data collection was performed by the method of testing, observation, and documentation. The result showed that the average difference between the value of post-test experimental class 1 and class 2 after the second experiment are given different treatment on the same material. Cognitive learning results were obtained from the pretest and posttest each class experiment. Results showed an increase of pretest and posttest scores in both the experimental class with an average value pretest experiment class 1 (MEA) 34 increased to 74 in the posttest and experimental class 2 (REACT) 39 increased to 84.97. Based on the results of this study, it can be concluded that the implementation of MEA and REACT learning models can improve learning outcomes of students. Student learning outcomes in the cognitive aspects of chemistry REACT was better than by MEA.
