<![CDATA[This study was aimed to know the differences in students' mathematical problem solving skills in problem basedlearning models with cooperative type thinking aloud pairs problem solving with a scientific approach at SMA Negeri 7 Bengkulu. Thedesign of this research was a quasi-experimental, used a pre-test post-test control group design. The population in this study were all students of class X MIPA SMA Negeri 7 Bengkulu consist of 6 classes, with samples consist of 3 classes, the first experimental class with the problem based learning model, the second experimental class cooperative learning model type thinking aloud pairs problem solving and conventional learning as a control class. The sampling technique used simple random sampling. Data collection was done by using a test of students' mathematical problem solving skills. The results of the research data were analyzed using one-way ANAVA test and BNT test. The prerequisite test used the Kolmogrove-Smirnov test to see normality and Bartlet's test to see homogeneity. The significant level used is 0.05. The research data showed that there was a significant difference in students' mathematical problem-solving ability in the learning model of Problem Based Learning, cooperative type thinking aloud pairs problem solving in SMA Negeri 7 Bengkulu, and problem based learning learning model which gives better results compared to the thinking type cooperative learning model thinking aloud Pairs problem solving at SMA Negeri 7 Bengkulu.Keywords: mathematical problem solving, PBL,TAPPS]]>
