The Effect of the Student Facilitator and Explaining Learning Model on the Mathematics Learning Outcomes of Harapan Mekar Middle School Students in Medan

The formulation of the problems in this study are: (1) how does the Student Facilitator and Explaining model influence the mathematics learning outcomes of SMP Harapan Mekar Medan students. (2) how to improve students' mathematics learning outcomes by using the Student Facilitator and Explaining model. The aims of this study were: (1) to find out how the use of the Student Facilitator and Explaining learning model influences student learning outcomes at SMP Harapan Mekar Medan. (2) to find out how to improve the learning process by using the Student Facilitator and Explaining model on student learning outcomes at Harapan Mekar Medan Middle School. The population and sample in this study were 24 grade IX students of SMP Harapan Mekar Medan, with 14 male students and 10 female students. This type of research is experimental research with the One Group Pretest Posttest research design. The research instrument used an essay test on exponential numbers and root shapes. Data collection techniques used the initial test (pretest) and the final test (posttest). Technical data analysis using the normality test. Hypothesis testing was used for the t test and determinant test. And the results of the study used the paired-sample t test using SPSS 22 which yielded a significance of 0.000 <0.05, so it was proven that H_adi was accepted H_0 was rejected. And the results of the determinant test carried out were obtained at 1.30%. So, it can be concluded that there is an influence of the Student Facilitator and Explaining learning model on the mathematics learning outcomes of SMP Harapan Mekar Medan students and the increase in learning outcomes using the Student Facilitator and Explaining model is 1.30%.
