ANALYSIS THE EFFECTIVENESS OF MATHEMATICS LEARNING USING CONTEXTUAL LEARNING MODEL

The purpose of this research was to determine whether learning mathematics using contextual learning model effectively in terms of students’ learning mastery, students’ learning activities, teacher’s ability to manage learning and students’ response. Method of research was quasi-experimental. Samples of research were students of grade XI AK1, consisted of 40 people. The instrument that used in this research was observation, which was used to research students’ learning activities, teacher's ability to manage learning, and students’ response. The test was used to research the students' learning mastery. The results showed an average of the overall indicator of the effectiveness of learning was increasing from the first meeting of 79.5%, the effective category, being 82.5% in the second meeting, on the effective category and 86.75% in the third meeting, on the effective category, This suggests that learning mathematics using contextual learning model effectively in terms of students’ learning mastery, students’ learning activities, teacher’s ability to manage learning and students’ responses.
