Mathematical Understanding Ability of Students through Contextual Teaching Learning at the Merchant Marine School

The purpose of this study is to analyze the ability of students' mathematical understanding through Contextual Teaching Learning. The subjects consisted of each of the two students of the Aceh Merchant Marine School DPIII, namely the high, medium, and low categories selected based on the results of the initial tests which refer to indicators of mathematical understanding. The instruments used were tests of mathematical comprehension abilities and interview guidelines. The data obtained were analyzed qualitatively and described descriptively qualitatively. The results showed that subjects with high and moderate abilities had excellent mathematical comprehension skills, and subjects with low ability had good mathematical understanding skills. Based on the results of these studies it can be concluded that the ability of mathematical understanding and motivation of students get satisfactory results through the Contextual teaching and Learning approach
