PENGARUH MODEL KOPERATIF TIPE NUMBERED HEADS TOGETHER (NHT) TERHADAP HASIL BELAJAR SISWA DALAM MATERI KOPERASI DI SD LABORATORIUM UNESA

The purpose of this study is to find out the effectiveness of cooperative learning type numbered heads together (NHT) application on student learning outcomes in cooperative materials in the Elementary School of Unesa Laboratory. In addition this study aims to determine the differences between the student learning outcomes by NHT cooperative learning type and the student learning outcomes by conventional learning in cooperatives materials in the Elementary School of Unesa Laboratory. NHT is a type of cooperative learning model that involves a number of students using four steps structure they are: numbering, asking questions, thinking together and answering. The hypothesis proposed in this study is that there are differences between the experimental class and the control class after being treated by NHT (Numbered Heads Together) learning type. The study applies random sampling techniques and data collection is done by making the learning and observation devices. The research population is students in the Elementary School of Unesa Laboratory. While the sample of this research is fourth-grade students who are divided into three classes namely trials class IV B, experimental class IVD and control class IV A. The validity used is the content and construct validation. Reliability in this study is tested by applying KR-20 techniques and inter-rater agreement. Data analysis is performed using T-test difference test with the aid of statistical program SPSS version 17 for windows. By analyzing research data, it is obtained that the difference is as amount 0.000. This shows that there are actually the differences between the experimental class and the control class after the treatment of NHT (Numbered Heads Together) learning type given. That is, the learning type NHT is proven effectively for improving students' abilities in comprehending Cooperative materials. This is supported by an increase in the average grade of the experimental group. The posttest grades are higher than pretest grade
