So it can be concluded that there is an effect of the treatment given a mathematical problem in the form of open-ended problems to the ability of students to solve linear program problems.Īl-Absi, M. This increase was statistically significant as evidenced by the one-party t-test where t count = 37.33> t table = 1.67 at α = 0.05, which means that Ha was accepted. This experiment showed success by obtaining an average test score of students when the pre-test was 39.58 which then increased when the post-test became 79.76. All data is processed using data analysis tools on Microsoft Excel. Student problem-solving performance was assessed using a holistic rubric. The influence test is performed using one-party t-test statistics. The homogeneity test uses the F-test statistics and the normality test uses the interpretation of skewness and kurtosis. Pre-test and post-test data have been tested both homogeneous and normally distributed. The validity of mathematical problems is based on expert judgment while the reliability is tested using product-moment correlation.

Data was collected through tests and interviews that were statistically analyzed both descriptive and inferential. This research is an experiment with one sample group, 28 students of class XI IPA-2 in SMA Negeri 7 Mataram. The purpose of this study is to determine whether the provision of linear program mathematical problems in the form of open-ended problems can affect students' problem-solving abilities.
