This research aims to know whether or not the effect of NHT (Numbered Heads Together)modelwith picture media of theagainst Biology student learning out comes in class VII SMP N 3 Rambah Samo. Type ofresearch is a quasiexperimental design withrandomized control group pretest posttest design. The population in this research were all learners of class VII. The research sample class VII-A as the experimental class and the class VII-B as the control class. Data collection techniques in this research is a test instrument in the form of multiple choice questions. Data analysis techniques for maan whitney testing using z test. The results showed the average value of learning outcomes is the experimental class 74,14 and control class 68,10. Based on the testing results, obtained tcount = 2,02, while ttable to significant level of 5% with n = 29 obtained ttable = 1,96. With the result that obtained zcount>ztable it can be concluded that there are significant discovery model of NHT with picture media of the learning out comes class VII SMP N 3 Rambah Samo
