IMPLEMENTASI MODEL THINK TALK WRITE (TTW) DENGAN LATAR MUSIK INSTRUMENTALTERHADAP PRESTASI BELAJAR MATEMATIKA SISWA KELAS VII SMP N 3 SRAGI

The problems of mathematics learning in SMP N 3 Sragi can be seen from the students’ achievement is still low. It can be known that the score of mathematic is still low from the criteria of minimum score was 70. In addition the mean result of mathematics in national examination in the academic year of 2012/2013 was 4.34 its decrease in academic year of 2013/3014 the means result mathematics was 3.76. So the expetation trough the use of Model Think Talk Write (TTW) with Assisted the Instrumental Music can give opportunity to the students to share their opinion. Meanwhile, the students’ achievement in mathematics can achieve the criteria of minimum score and the mean score is better.The result of the study showed that: 1) The mean of students’ achievement in experimental class was 74.06 with statistically it achieve the criteria of minimum score is 70. 2) The mean of students’ achievement in experimental class was 74.06 with statistically is better than the mean of students’ achievement in control class was 57.20. So, it can be concluded that the teaching learning using model TTW with assisted the background of instrumental music can be implemented in triangle material of the students of VII SMP N 3 Sragi.
