This study aims to determine the effect of applying the contextual teaching and learning model to the mathematical problem solving ability based on the learning independence of junior high school students. This type of research is an experimental research with 2x3 factorial experiment design with posttest only control group design at the end. The population in this study were all eighth grade students of mts guppi bandar sungai. The sampling technique used in this study was the random sampling cluster, with selected samples having an average similarity before treatment. Data collection techniques in this study were tests, questionnaires, observations and documentation. Data analysis techniques use two-way anova. For hypothesis 1 obtained f_a = 5,036> f_tabel = 4.01 so it can be concluded that there are differences in mathematical problem solving abilities between students who obtain learning by applying the contextual teaching and learning model with students who learn using conventional learning, with a higher average score good is the experimental class rather than control ie 41.94 and 38.92, respectively. For hypothesis 2 obtained f_b = 4.392> f_tabel = 3.16 so it can be concluded that there are differences in mathematical problem solving abilities between students who have high, medium and low learning independence, with an average score for students who have high learning independence 43.69 , was 38.63 and was low 42.83. For hypothesis 3 obtained f_ (a × b) = 0.302 <ftable = 3.16, so it can be concluded that there is no interaction effect between the learning model with
