Abstract

The main objective in this study was to determine the effect of learning models on open mathematical problem solving on understanding mathematical concepts by controlling numerical talent. This research was carried out in class X of Public High School 7 Denpasar with a quasi-experimental method with the design of The Non Equivalent Posttest Only Control Group Design, involving a sample of 72 students taken by simple random sampling technique. The independent variable in this study is the learning approach which is divided into two levels of factors, namely the learning model of solving open mathematical problems imposed on the experimental group and conventional learning models imposed on the control group. As the dependent variable in this study is an understanding of mathematical concepts. Numerical talent as a control variable (covariable). The research instruments were in the form of tests, namely tests of understanding mathematical concepts and numerical aptitude tests. Data analysis using one-way t-test and Anakova. The results showed that: (1) there was an influence of understanding mathematical concepts between students who followed the learning model of solving open mathematical problems with those who followed conventional learning models, 2) there was an influence of understanding mathematical concepts between students who followed the learning model of solving open mathematical problems with who followed the conventional learning model after numerical talent control was held.
