EFEKTIVITAS MODEL PEMBELAJARAN KOOPERATIF TIPE SNOWBALL THROWING TERHADAP HASIL BELAJAR MATEMATIKA SISWA

This research aims to determine the Effectiveness of the Cooperative Learning Model Snowball Throwing Type on students' mathematics learning outcomes. This type of research is a research experiment with research design One-Group Pretest-Posttest Design. The population of this study was XI SMKIT DBS 01 Batam Academic Year 2018/2019. The sampling technique is done by saturating sampling techniques with many students 19 students. The type of test given is a descriptive test consisting of 8 pretest questions and 8 posttest questions which then analyze the instrument using construct validity and reliability so that 8 valid and reliable questions are obtained with reliable values of pretest "0.684" and posttest "0.724" to be a matter of pretest and posttest. Normality test using Kolmogorov Smirnov with the results of normal pretest and posttest data. Hypothesis testing is done using the t test two correlated samples obtained sig. (0.00) ≤ . The results of this study indicate that the cooperative learning model of the snowball throwing type is effective against students' mathematics learning outcomes
