Abstract

This naturalistic qualitative research aimed to describe students mathematical critical thinking disposition in Socrates Contextual learning at the material of Linear Equations and Inequalities of One Variable. The subjects of this research were students of VII B class of SMP Negeri 19 Bandarlampung. Through purposive sampling techniques, it was chosen eleven students who was described their critical thinking disposition. The research data were obtained by observation, critical thinking disposition scale techniques, interviews and documentation. Before analyzing the data, researcher did the triangulation of data by interview. The data analysis techniques used three stages, which were reducting, displaying, and getting the conclusion of data. The results of this research was the students' mathematical critical thinking dispositions only appears on some students. For most of the other students, dispositions which appeared were not critical thinking disposition.Penelitian kualitatif naturalistik ini bertujuan untuk mendeskripsikan disposisi berpikir kritis matematis siswa dalam pembelajaran Socrates Kontekstual pada materi Persamaan dan Pertidaksamaan Linier Satu Variabel. Subjek penelitian ini adalah siswa kelas VII B SMP Negeri 19 Bandarlampung. Melalui teknik purposive sampling terpilihlah sebelas siswa yang dideskripsikan disposisi berpikir kritisnya. Data penelitian diperoleh dari observasi, teknik skala disposisi berpikir kritis, wawancara dan dokumentasi. Sebelum menganalisis data, peneliti melakukan triangulasi data melalui wawancara. Teknik analisis data menggunakan tiga tahapan, yaitu reduksi, penyajian, dan penarikan kesimpulan terhadap data.

Abstract

This qualitative research was aimed to describe the students mathematical discourse in Socratic Scientific learning to facilitate mathematical communication ability. The subject of this research was students of VII H class of SMPN 10 Bandarlampung in academic year of 2016/2017. The qualitative data of this research was about students mathematical discourse which were gotten by observation and interview. Three procedures of data analysis were data reduction, data display, and conclusion verification. Based on the research, it was concluded that in mathematical discourse, there were: (1) mathematical expression and written text as the dominant indicators of mathematical communication ability, (2) clarification as Socratic question that was used by teacher more frequently, and (3) communicating as Scientific phase that was more frequently appeared. Besides that, the research findings were characteristic pattern of mathematical discourse, mathematical discourse form, and the factors that influence students response in mathematical discourse. Penelitian kualitatif ini bertujuan untuk mendeskripsikan percakapan matematis siswa pada Pembelajaran Socrates Saintifik dalam memfasilitasi kemampuan komunikasi matematis. Subjek penelitian ini adalah siswa kelas VII H SMPN 20 Bandarlampung tahun pelajaran 2016/2017. Data penelitian ini merupakan data kualitatif tentang percakapan matematis siswa yang diperoleh melalui catatan lapangan dan wawancara.
