PENGARUH MODEL PEMBELAJARAN KOOPERATIF TIPE NUMBERED HEADS TOGETHER (NHT) TERHADAP HASIL BELAJAR MATEMATIKA SISWA KELAS VIII SMP NEGERI 1 RAMBAH SAMO

ABSTRACT: The purpose of this research was to determine  the effect of cooperative learning model Numbered Heads Together (NHT) on student’s mathematic learning outcomes of student of  8 grade Junior High School SMP N 1 Rambah Samo. This type of research was a quasi experimen with design Two-group posstest only. The population in this research were all class 8 grade Junior High School SMP N 1 Rambah Samo. Sampling was done by random sampling, so the class VIII B selected as experimental class and the class VIII C as a class control be sample. Instrument in this research was essay test that later tasted the validity, discrimination power, level of difficulty and reliability to determine whether or not to use. Liliefors normality test on the sample test showed that the experimental class and control class normal distribution. Homogeneity test with by F test showed that class of homogeneous. Based on the hypothesis testing performen by t test obtained t = 2,248 and t = 2,002. This means that thitung > ttabel , then H0 was rejected. This means that there were differences between the experimental class and the control class. It can be concluded that there were effect of the application of cooperative learning model Numbered Heads Together (NHT) to the mathematic learning outcomes of student class of 8 grade Junior High School SMP N 1 Rambah Samo.
