### EKSPERIMENTASI MODEL PEMBELAJARAN SSCS TERHADAP KEMAMPUAN DISPOSISI MATEMATIS DAN PRESTASI BELAJAR MATEMATIKA

#### Abstract

Abstract: The purpose of this study is to know which mathematics learning achievement and mathematical disposition of students better, students who are given SSCS learning model or students who are given expository learning method. The population of this study were all eighth grade students of Karanganyar N 3 Junior High School 2016/2017 school year consisting of eight classes with 256 students. The sample in the study amounted to 64 students consisting of experimental class and control class. The sampling technique used is *cluster random sampling*. Data collection methods use test and questionnaire methods. Analysis prerequisite test used is normality test using *Lilliefors* test, homogeneity test of variance using *Bartlett* test and balance test using t test. Data were analyzed using multivariate difference test statistic, then follow-up of multivariate statistic was done by univariate test. Based on hypothesis test (1) using multivariate mean difference test obtained result that and turns . So it was concluded that the average students' mathematical disposition ability and student achievement in SSCS and expository learning models were all not the same. (2) based on the univariate test of mathematical disposition of students obtained the test statistic and , it turns out so it concluded that the mathematical disposition of students with SSCS learning model is better than with the average ability of mathematical disposition of students with model expository learning. (3) based on univariate test of mathematics learning achievement of students that have been done obtained the price of test statistic and , it turns out so that it concluded that students' mathematics learning achievement with SSCS learning model is better than student's mathematics learning achievement with an expository learning model.

Keywords: Learning Achievement, Mathematical Disposition, SSCS.
