AbstrakPenelitian ini dilatarbelakangi oleh hasil penelitian-penelitian terdahulu yang menunjukkan masih rendahnya kemampuan komunikasi matematis dan self-confidence siswa dalam belajar matematika. Learning Cycle 7E merupakan salah satu model pembelajaran yang diharapkan dapat meningkatkan kemampuan komunikasi matematis dan self-confidence siswa. Tujuan dari penelitian ini untuk mengetahui peningkatan kemampuan komunikasi matematis dan self-confidence siswa yang mendapatkan model pembelajaran learning cycle 7E dengan yang mendapatkan model pembelajaran konvensional. Penelitian ini merupakan penelitian kuasi eksperimen dengan populasi siswa di salah satu SMP di Kabupaten Garut. Pengambilan sampel dilakukan dengan menggunakan teknik purposive sampling. Instrumen yang digunakan dalam penelitian ini berupas tes kemampuan komunikasi matematis dan skala sikap self-confidence siswa. Hasil analisis data menunjukkan bahwa peningkatan kemampuan komunikasi matematis dan self-confidence siswa yang mendapatkan model pembelajaran learning cycle 7E lebih baik daripada siswa yang mendapatkan pembelajaran konvensional. AbstractThis research is motivated by the results of previous studies which indicates the low ability of mathematical communication and self-confidence of students in learning mathematics. Learning Cycle 7E is one of the learning model that is expected to improve the ability of mathematical communication and self-confidence of students. The purpose of this study to determine the improvement of mathematical communication skills and self-confidence of students who get learning model of learning cycle 7E with which get the conventional learning model. This research is a quasi-experiment research with student population in one of junior high school in Garut. Sampling is done by using purposive sampling technique. The instrument used in this study examined the ability of mathematical communication and the scale of student self-confidence attitude. The result of data analysis shows that the improvement of mathematical communication ability and self-confidence of students who get the learning model of learning cycle 7E is better than students who get conventional learning.

The Difference

The purpose of this research was to know there was any difference in student’s mathematical communication ability in cooperative learning Think TalkWrite (TTW) type and Numbered Head Together (NHT) type. The population was all students at SMP Negeri 1 Lubuk Pakam. The sample was two classes which each consist of 36 students, VII A as experimental class I which taught by TTW and VII B as experimental class II which taught by NHT. The sample was taken by cluster random sampling. Collecting data technique of this research was mathematical comunication ability essay test that was given in the end of learning either in experimental class I or experimental class II. From the data analysis of each of experimental class were obtained that the average of posttest score in TTW classroom was higher than in NHT classroom. It was also obtained that score of mathematical communication indicators in TTW classroom was higher than in NHT classroom. From the data analysis of posttest score by using t-test with significance level α = 0.05, it was obtained that tcount = 4.687 and ttable = 1.667. It means that tcount > ttable then H0 was rejected and Ha was accepted. So, it can be concluded that there was difference of student’s mathematical communication ability who taught by cooperative learning model type TTW with NHT at SMP Negeri 1 Lubuk Pakam.

Advanced Organizer

Students’ low mathematical communication skill is influenced by several factors such as learning models applied by teachers in the classroom and the students’ learning motivation. Advanced organizer Model is appropriate to improve the students’ low ability. This study aims to determine whether: (1) there is an influence of advance organizer model toward the mathematical communication skill; (2) there is an influence of learning motivation toward the students’ mathematical communication skill, and; (3) there is an interaction between learning model and motivation toward mathematical communication skill. This research employs quasi-experimental design and the statistical analysis used is the two-ways variance with unequal cells. The result of this research shows that: (1) there is an influence of advance organizer model toward mathematical communication skill; (2) there is an influence of learning motivation toward students’ mathematical communication skill, and ; (3) there is no interaction between learning model and motivation toward mathematical communication ability.

This research is motivated by the importance of mathematical communication ability. Mathematical communication ability of students is still low. In order that this problem can be solved, a learning model that can enhance mathematical communication ability of students is required. In this research, CORE model learning with scientific approach was selected. This study aims to analyze the enhancement of mathematical communication ability. This research was a quasi-experimental with nonequivalent control group design. The population was students in eighth grade in one of the junior high schools in Jambi.  The sample consisted of two classes which were selected by purposive sampling. The instrument of this research is a test of mathematical communication ability. The data were analyzed by using Independent t-test. Based on the data analyzed, it is found that: The enhancement of mathematical communication ability of students who received the CORE learning model with scientific approach is better than the enhancement of students who received conventional learning.
