Abstract

Abstrak Penelitian ini bertujuan untuk mengetahui pengaruh penerapan metode pembelajaran kooperatif course review horay berbasis problem posing terhadap peningkatan hasil belajar siswa terkait materi perhitungan kimia. Metode pembelajaran kooperatif course review horay berbasis problem posing merupakan metode yang dapat membuat siswa berpikir aktif dalam mencari dan menemukan jawaban dari suatu permasalahan. Jenis penelitian ini merupakan quasi experiment. Desain penelitian yang digunakan adalah posttest design dan teknik pengambilan sampel menggunakan clustor random sampling. Uji statistika yang digunakan adalah uji normalitas, kesamaan dua varians, ketuntasan belajar, dan hipotesis. Uji ketuntasan belajar diperoleh rata-rata hasil belajar kelas eksperimen adalah 78,32 dengan 35 siswa tuntas dari 38 siswa dan kelas kontrol memiliki rata-rata 72,32 dengan 22 siswa tuntas dari 38 siswa. Uji hipotesis diperoleh angka korelasi sebesar 0,52 dan koefisien determinasi sebesar 26,23%. Dengan demikian disimpulkan bahwa metode pembelajaran kooperatif course review horay berbasis problem posing berpengaruh terhadap peningkatan hasil belajar siswa terkait materi perhitungan kimia. Kata Kunci: Course Review Horay; kooperatif; Problem Posing. Abstract This research aims to determine the effect of course review horay with problem posing to improve the student’s competence in stoikiometry. Learning method of cooperative course review horay with problem posing is a method of learning that can make the students to actively find the answer in a case. The type used in this research is a quasi experiment. The research design used was a posttest design and sample collection techniques using cluster random sampling. The statistic test used test normality, equality of two variances, hypothesis, completeness of learning The result of final stage of the analysis obtained an average of learning outcome experimental group is 78,32 within 35 passed students of 38 students, while the control group is 72,32 within 22 passed students of 38 students. The implementation of cooperative course review horay with problem posing on the experimental class scored a correlation of 0,52 and a coefficient of determination of 26,23%. So based on the result of the analysis from the final stage is cooperative learning course review horay with problem posing influence the student’s competence in stoikiometry.

Abstract

This study aims to measure the effect of application of Problem Based Learning (PBL) based module to critical thinking skill and student learning independence related to reaction rate material. PBL-based module is a module that can make students think actively in searching and finding answers from a problem. This type of research is an experiment. The research design used is posttest design and sampling technique using purposive sampling. The research instruments used were: cognitive test to measure students' critical thinking skill, questionnaire of learning independence, and questionnaire of student response to learning. Quantitative analysis result of experiment class score is 77,49 with 25 complete student from 28 students and control class has average 73,62 with 22 students complete from 29 students. Correlation test obtained correlation number of 0.37 and test the coefficient of determination obtained a number of 14.31%. Qualitative analysis found that overall showed that the experimental class was better than the control class. Thus it is concluded that the application of PBL-based module affect the improvement of critical thinking skills and student independence learning.
