Abstract

This study starts from the emergence of problems experienced directly by the author at the time of learning as the low student understanding of algebra, it is severe to the understanding of concepts in mathematics, because the concept of algebra can solve problems related to everyday life. In an effort to provide insight to student approach method writer chose is a Class Action Research (CAR), which combines methods poblem solving tries to study and reflect on a learning model with the aim of increasing understanding of the quality (both process and product) a lesson.

Abstract

Menurut beberapa siswa mereka mengatakan bahwa materi segitiga dan segiempat, sulit dan ada juga yang bingung saat menghitung keliling dan luas.LKS yang dikembangkan diharapkan dapat melatih kemampuan komunikasi matematis siswa untuk menerapkan dan memperdalam konsep matematika. Penelitian pengembangan adalah penelitian yang di gunakan untuk menghasilkan produk tertentu, dan menguji kefektifan produk tersebut. Berdasarkan ujicoba ahli terdapat beberapa masukan. Setelah mendapatkan masukan dari ahli maka dilakukan revisi kemudian baru dilaksanakan uji lapangan. Hasil pertimbangan para ahli dianalisis menggunakan statistik Q-Cochran hasil perhitungan menunjukkan bahwa signifikansi asimtotis 0,423 dengan nilai statistik Q = 6,000 dan nilai Q table (0.05;6) = 12.592. Karena nilai Q lebih kecil dari nilai tabel pada taraf signifikasi a = 0.05, dapat disimpulkan bahwa para penimbang telah menimbang validitas isi tiap butir soal secara seragam. Dan dapat disimpulkan bahwa LKS valid. Dari hasil evaluasi dapat disimpulakan bahwa rata-rata nilai siswa pada evaluasi pertemuan I adalah 82,85 dan rata-rata nilai evaluasi pertemuan II adalah 83,57, jadi dapat disimpulkan bahwa siswa sudah dapat menguasai materi yang ada pada LKS dan kemampuan komuniksi matematis siswa meningkat. Respon siswa terhadap LKS yang digunakan positif sebesar 94,45%. Keyword: Pengembangan, LKS, Komunikasi Matematis

Abstract

Penelitian ini bertujuan untuk mendeskripsikan keefektifan model Cooperative Learning type Team’s Game Tournament (TGT) pada pembelajaran matematika ditinjau dari kemampuan komunikasi matematis dan toleransi siswa kelas VIII SMP N 1 Sedayu tahun pelajaran 2016/2017. Penelitian ini adalah penelitian eksprerimen semu dengan pre-postest nonequivalent control group design. Penelitian ini menggunakan dua kelompok, yaitu kelompok eksperimen dan kelompok kontrol. Populasi penelitian mencakup seluruh siswa kelas VIII SMP N 1 Sedayu Bantul yang terdiri dari empat kelas. Dari populasi yang ada diambil secara acak dua kelas yaitu VIII A dan VIII C sebagai sampel penelitian. Pembelajaran matematika pada kelas VIII A menggunakan model Cooperative Learning tipe TGT dan pembelajaran pada kelas VIII C menggunakan metode konvensional. Instrumen penelitian ini adalah tes kemampuan komunikasi matematis dan angket toleransi siswa. Untuk menguji keefektifan pembelajaran dengan model Cooperative Learning tipe TGT dan metode konvensional yang ditinjau dari kemampuan komunikasi dan toleransi siswa dalam matematika, digunakan analisis one sample t-tes. Perbandingan Keefektifan model Cooperative Learning tipe TGT dan metode konvensional pada pembelajaran matematika yang ditinjau dari kemampuan komunikasi dan toleransi siswa, data dianalisis dengan menggunakan uji T2 hotteling. Uji-t univariat digunakan untuk menentukan pendekatan yang lebih efektif. Hasil penelitian menunjukkkan bahwa (1) penerapan model Cooperative Learning tipe TGT dan metode konvensional dalam pembelajaran matematika efektif ditinjau dari kemampuan komunikasi dan toleransi siswa, dan (2) Hasil uji lanjut menunjukkan bahwa model Cooperative Learning tipe TGT lebih efektif baik terhadap kemampuan komunikasi matematis maupun toleransi dibandingkan metode konvensional pada siswa kelas VIII SMPN 1 Sedayu.

Abstract

ABSTRACT: This study aims to determine the effect of learning model learning cycle and direct learning and mathematical belief in the ability of mathematical communications with quasi-experimental method and 2 x 2 factorial design treatment by level. Retrieving data using mathematical communication test instruments and mathematical belief questionnaire. The study population was the eighth grades students of SMPN in Tangerang on the Academic Year 2014/2015. Samples were taken by multistage random sampling technique. Analysis techniques using two-way ANOVA. The results showed that: 1) The ability to communicate mathematical students treated learning model learning cycle is higher than the direct learning, 2) There is an interaction effect between learning model belief mathematics to mathematical communication, 3) ability to communicate mathematical students treated learning model of learning cycle is higher compared to the treated directly on the learning group of students who have high math belief, 4) There is no difference in the ability of communication in the group of students who have low math belief.

Abstract

Mathematics is one of the basic subjects which is taught at every level of education, because it equips learners have the ability to think logically, analytically, systematicaly, critically and creatively, and the ability to solve problems and work together. In fact, many students do not have those abilities. One of the ways to improve their mathematical abilities is doing an effective learning with practical learning tools. In this study ARIAS learning model learning is as a tool of learning device. To achieve its practicality, learning devices are made to ease the teacher and student understanding. This study aimed to analyze the practicality of the learning device. This learning device is said to be practical if it has been tested in the experimental class and it gained positive response from students and teachers, and teacher has good interpretation when he manage his classroom activities. The result of this research is 79% of positive responses from teachers, and 87% positive responses from the students, and the average is 3.4 teachers manage the class well.

Abstract

This study aims to determine the activities of students in learning subjects through True or False strategy of graph theory by media index cards. Observations show a more focused student activity because students already know the material of what will be learned through the index cards that they get in early learning, and they also know the form of matter or issue that they get when studying the learning material on which they will carry. Students focus on the material presented by the lecturers. At the end of the students' learning spirit in concluding that material has been obtained. Lecturers also seem satisfied when getting feedback from students on material that has been given to the student lecturer. Keyword: true or false, cards, graphs, media
