Abstract
This study aims to find out the effect of applying a problem-posing approach on mathematical problem-solving ability. The research method used in this study is a quasi-experimental design with a post-test only control group design. Sampling techniques by applying cluster random sampling. The sample classes selected in this study were class XI MIPA 4 and XI MIPA 5 SMA Negeri 1 Jakarta. The instrument used in this study consist of 5 questions with polynomial as a topic to measure students mathematical problem-solving abilities. That five questions have gone through validity and reliability tests before being tested on the sample. The results of testing the statistical hypothesis using the t-test using the significance 0=0.05 were obtained t-count=5.389 > t-table=1.665 so that the application of learning with the posing problem approach had an effect on students mathematical problem-solving ability. In addition, the result of a large calculation of the influence with Cohen^s d Effect Size was obtained by 1,213. These results show that the posting problem approach has an 88% effect on students mathematical problem-solving abilities and falls into a large category.
Keywords: problem-posing approach, mathematical problem-solving ability, high school.
