Implementasi Kurikulum 2013 Terhadap Kemampuan Komunikasi Matematika Siswa Pada Materi Program Linear di Kelas XI SMA Negeri 2 Pematangsiantar TA 2016/2017

Abstract

This study aims to determine the improvement of students' mathematical communication skills with the implementation of the 2013 curriculum on linear program materials in grade XI SMA Negeri 2. This type of research is a classroom action research. This study measures students' mathematical communication skills. The test instrument of mathematical communication ability given to the students with the form of the test essay has been done by validating the instrument test and it is stated that the quality of the research instrument is significant, because by using the product moment formula obtained the lowest validity calculation 0.279 (low validity) and highest validity coefficient 0,829 (validity High) so that each test item is valid. Based on the conclusion of data obtained that the students' oral mathematical communication ability increased from 85% in the first cycle that is 34 students get good criteria and 6 students get enough criteria to be 90% in cycle II that is 36 students get good criteria and 4 students get enough criteria. While the student's mathematical communication ability increased from 62,5% in cycle I that is 25 students get good criterion and 15 students got enough criteria become 87,5% in cycle II that is 35 student get good criterion and 5 student get enough criteria.
