The research was based on concerns about the development of mathematical critical thinking and mathematical communication ability. The purpose of this study was review and compare the differences of enhancing mathematical critical thinking ability between junior high school students who acquire Model of Search, Solve and Share (SSCS) through hypnoteaching method and those who acquire the conventional learning. This study was a quasi-experimental research with non-equivalent control group design consists of classroom experiments which obtain Model of Search, Solve and Share (SSCS) through hypnoteaching method and control class which obtain conventional learning. The population of this study is junior high school students in Tangerang, where the samples are the grade 8th students in one of the state junior high school in Tangerang. Instruments used to collect data in this research consists of mathematical critical thinking test instruments, student’s attitude scale, and observation sheets. The data obtained is analyzed using the mean difference test, which are the t-test, Mann-Whitney, and Rank-Spearman test. The results showed that the enhancement student’s mathematical critical thinking ability who gotten model os Search, Solve, Create, and Share (SSCS) through hypnoteaching method is better than who gotten conventional learning.

The ability to think critically is one of the highest levels of ability. Developing critical thinking skills in students is still considered important to be improved in schools so that students are able and accustomed to facing various problems around it. This study aims to analyze the critical thinking skills of junior high school students who are in excellent classes and regular classes. This research was conducted in Bandung Barat. In this study students are given a test in the form of questions with critical thinking skills, the problem is used to compare between the superior class and ordinary class. Assessment of the problem using several factors of critical ability include 1) students can not understand the problem correctly, 2) students rush in doing the problem, 3) the students cannot choose the problem-solving strategy correctly and 4) the students work on the problem systematically. Then the matter of critical thinking skills of mathematics is analyzed using quasi-experimental research method to analyze students' critical thinking ability that influence learning result. This study shows the differences in critical thinking ability of junior high school students who are in excellent class and ordinary class. This study shows that superior classes are better in mathematical critical thinking ability than a regular class. The results of this study can add knowledge about critical thinking mathematics junior high school students who are in the class and ordinary class and used to facilitate for educational practitioners in the development of critical mathematical thinking skills.

This study was aimed to investigate the implementation of Jigsaw Cooperative Learning Model applied by Christian religious education teachers in improving grade 7 students’ learning creativity at SMP 3 Sipoholon. The participants were 23 junior high school students. Observation sheet was used to collect data. The following data analysis was conducted, namely data reduction, data exposure, and conclusion. The result of study revealed that students’ learning creativity has increased in the first cycle, reached 26.96%. It was applied 64% of the expected and was in the sufficient category. In the second cycle, students’ learning creativity reached 64.35% and had increased 37.39%. it was applied 80% of the expected and was in the strong category. Finally, students’ learning creativity in the third cycle reached 80,87% and had increased 16.52%. It was applied 96% of the expected and was in the stronger category. Therefore, it can be concluded that the implementation of the Jigsaw Cooperative Learning Model can improve the creativity of Christian religious education learning among junior high school students.BAHASA INDONESIA ABSTRACT: Penelitian ini bertujuan untuk mengetahui bagaimana Implementasi Model Pembelajaran Kooperatif Jigsaw oleh Guru PAK Untuk Meningkatkan Kreativitas Belajar Siswa kelas VII SMP Negeri 3 Sipoholon. Subjek dalam penelitian ini adalah kelas VII yang berjumlah 23 siswa, dan objek penelitian ini adalah model pembelajaran kooperatif jigsaw. Dalam pengambilan data, teknik yang digunakan adalah lembar observasi. Sedangkan teknik analisis data dengan reduksi data, paparan data, dan penarikan kesimpulan. Dari data hasil observasi menunjukkan bahwa kreativitas belajar siswa mengalami peningkatan pada siklus I kreativitas belajar siswa mencapai 26,96%, pada siklus II kreativitas belajar siswa mencapai 64,35% mengalami peningkatan 37,39%, dan pada siklus III kreativitas belajar siswa mencapai 80,87% mengalami peningkatan sebesar 16,52%. Untuk penerapan model pembelajaran jigsaw yang diterapkan oleh guru PAK mengalami peningkatan. Pada siklus I diterapkan 64% dari yang diharapkan dan berada pada kategori cukup. Pada siklus II diterapkan 80% dari yang diharapkan dan berada pada kategori kuat. Pada siklus III diterapkan 96% dari yang diharapkan dan berada pada kategori kuat. Berdasarkan penelitian yang dilakukan dapat bahwa penerapan model pembelajaran kooperatif jigsaw oleh guru PAK dapat meningkatkan kreativitas belajar Pendidikan Agama Kristen di kelas VII SMP Negeri Negeri 3 Sipoholon, Kecamatan Sipoholon T.P 2017/2018 dan mencapai 70-90% dari yang diharapkan.Keywords: Cooperative jigsaw learning model; student learning creativity; students
