<![CDATA[Based on the results of data analysis and discussion that have been carried out regarding the application of the Problem Based Learning model with the help of the Brain Math application on students' mathematical reasoning abilities, it was obtained that the t-test results obtained t_(count)> t_(table) (8.70> 1.672) then H_(0) was rejected and H_(1) was accepted. So it can be concluded that there is an influence of the Problem Based Learning model on students' mathematical reasoning abilities. This means that the mathematical reasoning abilities of students who are taught using the Problem Based Learning model with the help of the Brain Math application are better than the mathematical reasoning abilities of students who are taught using the direct learning model.]]>
