Peningkatkan Kemampuan Berpikir Kritis dan Hasil Belajar Matematika Materi Program Linear Melalui Model Pembelajaran Kontura Pada Siswa Kelas XI IIA MAN Karanggede

Abstract

Abstract. This study aims to improve Critical Thinking Ability and mathematics learning outcomes of linear program material through the KONTURA learning model in class XI IIA MAN Karanggede in semester 1 of the school year 2017/2018. The KONTURA Learning Model is a combination of Contextual Learning Models and Peer Tutors and uses GeoGebra media.
 This type of research is Classroom Action Research conducted in two cycles with research subjects in class XI IIA MAN Karanggede in semester 1 of the year 2017/2018, totaling 25 children consisting of 9 men and 16 women. Data collection techniques used were observation, documentation, tests and questionnaires. Data analysis used included qualitative data analysis, namely data reduction, data presentation, and conclusion, as well as quantitative data analysis, namely the assessment of Critical Thinking Ability and peer observation of the implementation of the KONTURA learning.
 The results of this study indicate that Critical Thinking Ability and Mathematics student learning outcomes through the KONTURA learning model in class XI IIA MAN Karanggede in the first semester of the 2017/2018 academic year can increase. Improved Critical Thinking Ability can be seen from the results of the questionnaire Critical Thinking Ability with the following results: High Critical Thinking Ability there are 3 students (12%), after the application of the KONTURA learning model the students' Critical Thinking Ability increases to: High Critical Thinking Ability there are 22 students ( 88%), there is a 76% increase. Student learning outcomes can increase from the number of students who get very good grades there are 0 students or 0%, the number of students who get good grades there are 0 students or 0%, after applying the KONTURA learning model the learning outcomes increase: the number of students who get very high scores either there is 1 student or 4%, the number of students who score well is 5 students or 20%, there is a 24% increase.
