Penerapan Model Pembelajaran Kooperatif Tipe Course, Review, Horay (Crh) Terhadap Kemampuan Komunikasi Matematis Dan Self-Efficacy Siswa

The research was distributed by the importance of mathematical communication skills and self-efficacy of students. This research aims to assess the application of the cooperative learning model of the CRH type (Course, Review, Horay) against mathematical communication skills and self-efficacy of MTs students. Design research used are Nonequivalent Control Group Design. The population are grade VIII students of MTs Assalaam. And the sample, consist of 20 students of CRH class (experimental group) and 20 students of conventional class (control group) were selected by purposive sampling technique. Issues that are examined, namely the improvement of mathematical communication ability of students ' self-efficacy, diversity, the relationship between mathematical communication skills and self-efficacy, the influence of self-efficacy after learning, as well as the activity of students against mathematics learning with a model response cooperative type CRH. Quantitative analysis using independent sample t-test, Mann-Whitney test, and Pearson correlation test Correlation, while the qualitative analysis done for descriptive. The results showed an increase in mathematical communication skills students acquire learning cooperative learning model with CRH type better than students who get conventional learning, self-efficacy of students who get the learning model cooperative type CRH is no better than students who get conventional learning, there is a relationship between the mathematical communication and self-efficacy of the students, self-efficacy after learning were in the category of medium, as well as the activity of students against mathematics learning with a model response cooperative type CRH increases.
