This study is an experimental research that aims to determine the effect of Problem solving approach to solving mathematical problems in fifth grade. The population in this study is all students of class V SD Islam Athirah Bukit Baruga academic year Makassar 2014/2015 consisting of four classes. The sample of research is two classes, namely experimental class and control class. Each class consists of 26 students. Both classes were obtained by purposive sampling technique. To obtain the required data, the study was conducted in both sample classes. A technique of data collecting was done by observation and test. Data analysis techniques used were descriptive and inferential statistical analysis techniques. The results obtained from the descriptive statistical analysis are: (1) The ability to solve the problem of mathematics of students who were taught by using Problem solving approach is in qualification capable with the average value of 74.7 and the standard deviation of 21.6; (2) Ability to solve math problems of students who are taught without using Problem solving approach in qualification less able with average score 55,7 and standard deviation 16,2. From the results of inferential statistical analysis obtained that ability to solve the problem of mathematics students who are taught by using Problem solving approach is better than who taught mathematics without using Problem solving approach. From the results of this study can be concluded that the application of Problem solving approach in learning mathematics affects the ability to solve mathematical problems. © 2018 Published under licence by IOP Publishing Ltd.
