CONTRIBUTION OF HABITS OF MIND TOWARDS STUDENT MATHEMATICAL LITERACY ABILITY ON GEOMETRY.<strong> </strong>The relationship between habits of mind with mathematical literacy ability is the basis of this research. The purpose of this study was to determine the description of students 'habits of mind and the influence of habits of mind on students' mathematical literacy ability. This research is an ex post facto method. Through a purposive sampling technique selected 35 students of class VIII at one of junior high school in Bandung. Students work on geometry problems in the material to build flat side spaces and habits of mind scale. The results found that habits of mind had a positive contribution on students' mathematical literacy ability by 43.5%. It can be concluded to improve students' mathematical literacy ability by increasing habits of mind.
The urgency and proficiency of students’ mathematical literacy in Bandung that have not been optimal are the basis of this study. The aim of this study is to explain the enhancement of students' mathematical literacy proficiency due to the implementation of the inquiry co-operation model (experimental class) and conventional learning (control class) in terms of basic mathematical proficiency. This study is a quasi-experimental study with a non-equivalent control group design, and the research subjects were seventy students of class VIII of Bandung that were selected through a purposive sampling technique. The research data was obtained through mathematical literacy tests of material in a polyhedron. The results of the data analysis showed that: (1) the enhancement in mathematical literacy proficiency of the experimental students class was better than the control studentsclass in terms of the basic mathematical proficiency (high and medium); (2) there is no significant difference in the increase of mathematical literacy proficiency in experimental students class in terms of the basic mathematical proficiency. It can be concluded that inquiry co-operation model espouses the enhancement of students' mathematical literacy proficiency.
Penelitian ini ditujukan guna menganalisis dan mendeskripsikan kemampuan berpikir kritis matematis siswa kelas X SMK Negeri 1 Kudus berdasarkan tingkat self-confidence yang dimiliki. Subjek yang digunakan yaitu 3 peserta didik kelas X jurusan Akuntansi SMK Negeri 1 Kudus dimana ketiganya memiliki tingkat kepercayaan diri yang berbeda, yaitu tinggi, sedang, dan rendah. Penelitian ini merupakan penelitian eksploratif dengan pendekatan deskriptif kualitatif. Pengumpulan data dilakukan dengan memberikan angket self-confidence, tes kemampuan berpikir kritis, serta wawancara. Untuk menganalisis data, teknik yang digunakan yaitu reduksi data, penyajian data, dan penarikan kesimpulan. Sedangkan untuk keabsahan data digunakan teknik triangulasi waktu. Dari penelitian ini dapat ditarik kesimpulan bahwa semakin tinggi tingkat self-confidence peserta didik maka semakin baik pula kemampuan berpikir kritis matematis peserta didik tersebut, begitupun sebaliknya.
