<![CDATA[This study aims to see whether there is or not the effect of the cooperative numbered head together learning model on the mathematics learning outcomes 9th grade students of SMPN 6 Bengkulu City. The type of research was a quasi-experimental design with The Nonequivalent Pretest-Posttest Control group design. The population in this study were all students of class IX SMPN 6 Bengkulu City. The sample selection used simple random sampling technique, the sample in this study was class IX A which consisted of 25 students as the experimental class and class IX B which consisted of 25 students as the control class. Data collection was carried out using questions pretest and posttest. The results of the hypothesis test showed the sig (2- tailed) value is 0.000 < α = 0.005, with an average student posttest score experiment class of 75,88 and an average student posttest score control class of 58,84. It can be concluded that there is a significant influence of the cooperative Numbered Head Together learning model on the mathematics learning outcomes 9th grade students of SMPN 6 Bengkulu City.]]>
