<![CDATA[This qualitative and descriptive research was aimed to describe the disposition of the students critical thinking mathematical in Scientific Socratic learning. The subject in this research were students of class VII-L of Junior High School 20 Bandar Lampung odd semester in academic year of 2016/2017. The qualitative data of this research was about disposition of students critical thinking mathematical wich were taken by field notes, interview, and documentation. The technique of data analysis used three stages such as reduction, presentation, and conclusion of data. Based on the results of the research, it was concluded the students who have high, middle and low mathematical ability can lead to the critical thinking of disposition in Scientific Socratic learning on materials Linier Equations and Inequations material One Variabel. The dominant indicator of disposition students critical thinking mathematical appear is open-minded indicators.Penelitian kualitatif deskriptif ini bertujuan untuk mendeskripsikan disposisi berpikir kritis matematis siswa dalam pembelajaran Socrates Saintifik.
