PENGARUH MODEL SELF REGULATED LEARNING TERHADAP KEMAMPUAN KOMUNIKASI MATEMATIS SISWA KELAS X SMA

Abstrak

Penelitian ini bertujuan untuk mengetahui perbedaan kemampuan komunikasi matematis antara siswa yang dibelajarkan dengan model self regulated learning dan siswa yang dibelajarkan dengan model pembelajaran ekspositori. Jenis penelitian ini adalah eksperimen semu dengan desain penelitian posttest-only nonequivalent control group design. Populasi pada penelitian ini adalah seluruh siswa kelas X SMA Negeri 2 Singaraja tahun ajaran 2013/2014. Pengambilan sampel dilakukan dengan teknik random sampling. Data skor kemampuan komunikasi matematis siswa diperoleh melalui tes yang berbentuk uraian, dan dianalisis menggunakan uji-t dengan taraf signifikansi 5%. Hasil pengujian hipotesis menunjukkan bahwa kemampuan komunikasi matematis siswa yang dibelajarkan dengan model self regulated learning lebih tinggi daripada kemampuan komunikasi matematis siswa yang dibelajarkan dengan model pembelajaran ekspositori. Dengan demikian, dapat disimpulkan model self regulated learning memberikan pengaruh positif terhadap kemampuan komunikasi matematis siswa.
Kata Kunci : model self regulated learning, model pembelajaran ekspositori, kemampuan komunikasi matematis

This research aimed at describing the difference of mathematical communication ability between the students who taught with self regulatid learning model and the students who taught with expository learning model. This research was quasy experimental research by using posttest-only nonequivalent control group design. The population of this research was all of 10th grade students of SMA Negeri 2 Singaraja in the academic year 2013/2014. The sample was taken by using random sampling technique. The data of students' mathematical communication ability scores were obtained using essay test. These data were analyzed by using t-test with significant level was 5%. The results showed that mathematical communication ability of students who taught with self regulated learning model was higher than the one of students who taught with expository learning model. Thus, it may be concluded that self regulated learning model has a positive influence of the students’ mathematical communication ability.
