<![CDATA[This study aims to determine the effect of the DMR model with the CBSA approach to the ability of mathematical representation, the effect of students’ learning motivation on mathematical of interaction between learning models and learning motivation on the mathematical representation ability of grade VII students of state junior high school 19 Bandar Lampung. This type of research is Quasi-experiment and design used is post-test only control. The population of this study was all students of class VII of state junior high school 19 Bandar Lampung. The technique used for sampling is cluster random sampling. The sample in this study were students of clas VII B as the experimental class and students of class VII C as the control class. The testing of hypothesis uses two-way analysis of variance with unequal cell. The results obtained in this study are: (1) there is an influence between the DMR learning model and the CBSA approach to mathematical representation abilities; (2) there is influence between students who have high, medium and low learning motivation towards mathematical representation abilities; (3) there is no interaction between the learning model and learning motivation towards the ability of mathematical representation.]]>
