Education is a conscious and planned effort organized by school institutions to guide and train learners to grow awareness about the existence of life and the ability to solve every problem of life that always arises. It is reminded that teaching and learning activities are held in order to provide students with learning experiences. Selection of learning models used by teachers in delivering taught material can affect learning outcomes. One model of cooperative learning is Teams Games Tournament (TGT) model. The TGT learning model is a group learning model that involves student activity with an exchange of thoughts or ideas constructing knowledge amongst students in groups when getting assigned. This research is a Classroom Action Research (PTK) or Classroom Action Research is a research that is intended to provide information on how appropriate action to improve teachers' ability and student activeness. The results of the implementation of the first cycle of action I have achieved the classical indicator that has reached 62.5% students score above 70 and the results in cycle II reach 92% students score above 70.

AbstractIn general, the purpose of this research is to find out whether there is relationship between students’ self-confidence and students’ mathematic problem solving skill. The method of this research is survey method with corellation technique. The population of this research is students of a state junior high school in Bandung. While, the sample of this research is 35 students which is decided by purposif sampling in a state junior high school in Bandung. The instrument in this research is test and non-test instrument, in which test instrument consists of six questions to analyze students’ mathematic problem solving skill, while non-test instrument consists of twenty five scale statement which is used to analyze students’ self-confidence in mathematic learning. Conclusion of the result of this research is significantly , students’self-confidence in mathematic learning influence students’ mathematic problem solving.
Buku pelajaran menjadi salah satu peranan penting dalam meningkatkan kemampuan matematis dan hasil belajar siswa. penelitian ini bertujuan untuk menganalisis konten pada buku cetak yang banyak dipakai di Indonesia dan china. Objek pada penelitian ini adalah materi peluang dan statistik pada SMA kelas 12. Metode penelitian yang dipakai pada penelitian ini adalah deskriptif kualitatif. Textbook dianalisis dari beberapa aspek penting seperti susunan materi peluang dan statistic, pembagian jam mata pelajaran dan analisis yang dilakukan pada soal latihan. Hasil pada penelitian ini menunjukkan bahwa jam mata pelajaran di Indonesia lebih banyak 14 jam mata pelajaran dibanding di china. Susunan materi peluang dan statistik di Indonesia lebih banyak di banding susunan materi peluang dan statistic di Indonesia. Jumlah soal latihan pada Indonesian textbook lebih banyak dibanding chinese textbook. Tetapi jumlah type soal applying dan reasoning pada chinese textbook lebih banyak dibanding Indonesia textbook. siswa di Indonesia terbiasa dengan banyak latihan soal. Sedangkan siswa di china lebih fokus pada poin-poin penting dan meningkatkan kemampuan high order thinking (HOT) siswa. diharapkan penelitian ini dapat menjadi bahan pertimbangan pada penyusunan textbook pada kurikulum selanjutnya pada dua Negara.
