Abstract

The purpose of this research was to know the difference between the use of cooperative learning methods consisting of the think talk write (TTW) method and the think pair share method (TPS) on mathematical communication ability in algebraic forms operating materials. The method used in this research was a quantitative research method using a comparative study approach. The sampling technique used in this study was Cluster Random Sampling. The population of this study consisted of all VII grade students of SMP Negeri 2 Ngabang in the 2019/2020 school year. The research sample was experimental class I namely class VII A using the TTW method and experimental class II namely class VII B using the TPR method. Data was collected using test and documentation. The data analysis technique used was the t-test. The results of this research showed  that the   of 2.049 was greater than the   of 1.995 at the significance level α = 0.05. This means that there were significant differences in the results of students' mathematical communication ability in the aspects of knowledge between the experimental class I compared to the experimental class II. This showed that the experimental class I who followed the learning by applying the Think Talk Write method has a different mathematical communication ability than the experimental class II who followed the learning by applying the Think Pair Share method.

Abstract

ABSTRAK Pendidikan karakter telah menjadi pembahasan menarik bagi pelaku pendidikan semenjak zaman Ki Hajar Dewantara. Referensi mengenai pendidikan karakter tidak berhenti diterbitkan, begitu juga jurnal-jurnal pendidikan yang mengupasnya kemudian mempublikasikannya dengan tujuan pelaku pendidikan tidaklah lagi merasa awam terhadap pendidikan karakter. Namun sejauh ini, penanaman karakter kepada peserta didik di sekolah, masih berupa wacana yang pada akhirnya tujuan pendidikan yang tertera pada Undang-Undang nomor 20 tahun 2003 serta cita-cita bangsa belumlah terwujud. Berbagai permasalahan di luar yang berhubungan dengan moral peserta didik, masih terus ada dan menjadi isu yang biasa didengar. Kajian ini membahas mengenai penanaman karakter diri peserta didik melalui pembelajaran matematika di sekolah yang tentunya dikembalikan dengan kesesuaian tujuan pendidikan dan cita-cita bangsa. Kajian ini juga mengarah pada pendidikan karakter yang direncanakan secara terstruktur oleh pelaku pendidikan agar pendidikan karakter dapat dilakukan secara konsisten. KATA KUNCI: pendidikan karakter, pembelajaran matematika
