Application of Mathematical Software on Problem Based Learning Model for the Mathematical Conceptual Understanding

the purpose of this research to determine whether the understanding of mathematical concepts of students who take part in learning the use of mathematical software in problem based learning models is better than understanding the mathematical concepts of students who take conventional learning. In this study, the type of research used is quasi-experimental research design is the Post Test Only Control Group Design. The population of this research is senior high school students. The sample of this study was 2 classes taken using random sampling technique. Data in this study are the understanding of mathematical concepts collected using the description test. The research data were then analyzed using one-tailed t-test with a significance level of 5%. The results showed that t-count = 2.9 and t-table = 1.7 so that the value t-count> was obtained was obtained based on that H0 was rejected. This means that the understanding of mathematical concepts of students who follow the use of mathematical software in the problem based learning model is better than understanding the mathematical concepts of students who follow conventional learning. In other words there is a positive influence of the use of mathematical software in the problem based learning model of understanding students' mathematical concepts.
