This type of research is quasi-experimental with the form of Nonequalivalent control group design. The samples on this study were by using saturated sampling because of the relatively few population counts. The results of N- gain analysis shows that conventional learning models in the control class gained 0.29 with less criteria while the experimental class with the implementation of the Two Stay Two Stray Learning model received 0.39 with moderate criteria. The ttest results show that tvalue is 2.104 while ttable is 2.001 or tvalue > ttable and the significance of it is 0.000 so H0 is rejected. The linear regression test of Two Stay Two Stray models on the student's mathematical learning results of a 89.3% space build. The conclusion of the study was (1) there were differences in the learning outcomes of the space between students in the control class without the implementation of the Two Stay Two Stray Learning model and the experimental class with the adoption of the Two Stay Two Stray Learning model, (2) there was a significant influence on the material's learning to build space on the experimental class with the adoption of the Two Stay.
