TPS type learning model is a learning model that acts as an assistant to the implementation of learning so students can be given the opportunity to think and work together. This cooperative model aims to achieve the goals and skills of teaching students how to solve mathematical problems and foster a mathematical liking. The research objective is to determine the effect of learning outcomes in students' mathematical problem solving abilities. This research uses experimental research. The research sample was taken by 2 (two) schools chosen by Ramdom Sampling (Random). The results showed that the results of the probability analysis (sig) = 0.569> α (0.05), then H0 was accepted and H1 was rejected. In conclusion there is no difference in the ability to solve mathematical problems between the experimental class and the control class.
