PENGARUH CONTEXTUAL TEACHING AND LEARNING TERHADAP PEMAHAMAN KONSEP MATEMATIS SISWA
Get PDFThis research aimed to find out the influence of contextual teaching and learning towards students mathematical conceptual understanding. The population of this research was all students of grade ninth of SMP 4 Gedong Tataan in odd semester academic years of 2014/2015 as many as 143 students that was distributed into four classes (IXA - IXD). The samples were taken by purposive sampling and it was obtained students of IX D as experimental class and IX C as control class. This research used post-test only control design. The data of this research were score of students mathematical conceptual understanding which was obtained by test. Based on the results of data analysis, it was known that the students mathematical conceptual understanding with CTL was higher than conventional learning. Thus, the implementation of CTL affects towards students mathematical conceptual understanding.Penelitian ini bertujuan untuk mengetahui pengaruh contextual teaching and learning terhadap pemahaman konsep matematis siswa.
