Abstract

This research is by the use of learning model Ekspositori that has been causing low mathematics learning results so that other learning models are needed. This study aims to determine the effectiveness of cooperative learning model type group investigation of mathematics learning outcomes of students of class X SMAN 1 Sewon Bantul district even semester 2017/2018 academic year.

            This research type is quantitative research with population of student of class X SMAN 1 Sewon Regency of Bantul academic year 2017/2018 consisting of 5 class. Samples were determined using random sampling technique and obtained class X MIPA 2 as experimental class and class X MIPA 5 as control class. Data collection techniques used are True Experiment Design with Posstest-Only Control Design. The instrument test used is the test of validity, test of different power, and reliability test. Data analysis technique used for prerequisite test is normality test, homogeneity test and hypothesis test include t-test.
            Based on result of t-test of two parties obtained  = 2,254148 and = 2,00342 where  which mean that there is difference of result of student learning of mathematics using cooperative type study model of Group Investigation by using model of Expository learning at class X SMAN 1 Sewon Bantul District even semester of 2017/2018. And Based on t-test results one party obtained  = 2.254148 and  = 1.672595 where

 which means that cooperative learning model type of group investigation more effective than the model of expository learning of mathematics learning outcomes of students of class X SMAN 1 Sewon Bantul District even semester of academic year 2017/2018.
