Abstract
Penelitian ini bertujuan untuk mengetahui penerapan model pembelajaran Think Talk Write dengan media tangram berpetak terhadap kemampuan komunikasi matematis siswa SD. Jenis penelitian ini merupakan penelitian
kuantitatif menggunakan desain quasi experimental dengan bentuk non equivalent control group design. Populasi dalam penelitian ini adalah
seluruh siswa kelas IV SD Negeri 02 Penggarit Pemalang yang berjumlah
28 siswa dan seluruh siswa kelas IV SD Negeri 01 Kejambon Pemalang yang berjumlah 28 siswa. Sampel penelitian ini adalah kelompok siswa
kelas IV SD Negeri 02 Penggarit sebagai kelas eksperimen dan kelompok siswa kelas IV SD Negeri 01 Kejambon sebagai kelas kontrol.
Pengumpulan data kemampuan komunikasi matematis siswa dilakukan dengan teknik wawancara, tes essay, observasi, dan dokumentasi. Data yang diperoleh dianalisis dengan menggunakan uji-t. Berdasarkan hasil
analisis diperoleh ��ℎ������𝑔 = 3,789 dengan α = 5% dan dk = 28 + 28 – 2 =
54 diperoleh �������𝑙 = 2,007. Jadi ��ℎ������𝑔 > �������𝑙 , yaitu 3,789 > 2,007
maka H0 ditolak dan Ha diterima, sehingga penerapan model pembelajaran
Think Talk Write dengan media tangram berpetak efektif terhadap
kemampuan komunikasi matematis siswa SD. Nilai rata-rata siswa kelas eksperimen yaitu 88,57 lebih tinggi daripada nilai rata-rata kelas kontrol yaitu 77,93. Dengan demikian dapat disimpulkan bahwa penerapan model pembelajaran Think Talk Write dengan media tangram berpetak efektif terhadap kemampuan komunikasi matematis siswa SD.
Kata Kunci: think talk write, komunikasi matematis
Abstract
This study aims to determine the implementation of Think Talk Write
learning models with tangram plotted media to elementary students' mathematical communication skills. Kind of this study is a quantitative study using a quasi experimental design with a non equivalent control group design. The population is all fourth grade students of Elementary School 02 Penggarit Pemalang amounted to 28 students and all fourth grade students of Elementary School 01 Kejambon Pemalang amounted 28 students. The sample of this study is group of students of Grade IV of SDN
02 Penggarit as experiment class and student group of class IV SDN 01
Kejambon as control class. Data colection of students’ mathematical
communication skills is by interview, essay tests, observation, dan documentation. The data obtained were analyzed using the t-test. Based on the results of the analysis obtained t_calculation = 3.789 with α = 5% and dk = 28 + 28 - 2 = 54 obtained t_table = 2.007. So t_calculation > t_table, which is 3.789> 2.007 then H0 is rejected and Ha is accepted, so that the implementation of the Think Talk Write learning model with tangram plotted media is effective for elementary students' mathematical communication skills. The average value of the experimental class is 88.57 higher than the average value of the control class which is 77.93. Thus, it can be concluded that the implementation of the Think Talk Write learning model with tangram media is effective for the elementary students' mathematical communication skills.
