THE APPLICATION OF CONTEXTUAL TEACHING AND LEARNING (CTL) APPROACHMENT TO IMPROVE THE STUDENT’S ACTIVENESS AND MATHEMATICAL CONNECTION SKILLS IN CLASS VIIIF OF SMP NEGERI 1 JATEN KARANGANYAR IN ACADEMIC YEAR OF 2015/2016. Thesis. Teacher Training and Education Faculty of Surakarta Sebelas Maret University. June 2017. This research aimed to improve student’s activeness and mathematical connection skills in class VIIIF of SMP Negeri 1 Jaten in academic year of 2015/2015 using Contextual Teaching and Learning (CTL) approachment to the flat-side spatial structure. This study was a Classroom Action Research conducted in 2 cycles. Each cycle consisted of four stages: planning, acting, observing, and reflecting. The subject of research was students in class VIIIF of SMP Negeri 1 Jaten in academic year of 2015/2016. Data that collected in this research is data about student’s activeness and mathematical connection skills. Data student’s activeness pbtained from observations during the learning process, while data mathematical connection skills from the result of test in final cycle. Indicator of the successful on this research is each indicator includes indicator visual activity and listening activity to reach 75%, indicator oral activity and writing activity to reach 70% as well as at least 30% of students have achieved good category to each indicator student’s mathematical connection skills. From the result of observation in cycle II, the mean percentage student activeness obtained reach to 80.74% with visual activity of 81.26%, verbal activity of 74.48%, listening activity of 84.38%, and writing activity of 82.82%. Meanwhile from the result of test in cycle II, student’s mathematical connection skills at indicator of intertopic and mathematical procedures with good category was increased reach to 46.88% and for connection skill of real life was increased reach to 34.38%. Based on the research, it could be concluded that the application of CTL approachment could improve student’s activeness and mathematical connection skills in class VIIIF of SMP Negeri 1 Jaten in academic year of 2015/2016 in flat-side spatial structure. It was because such the learning approachment: (1) Teacher gives problems in real life that can foster the student’s mathematical connection skills (Modeling); (2) While solving Student Worksheets, students are trying to active found the concepts of material is being studied (Inquiry); (3) Groups of students solving Student Worksheet to construct knowledge about the material being studied (constructivism and community learning); (4) The group presentation gives students an opportunity to ask questions and respond to other groups (Ask); (5) Students get appreciation and solving individual quiz (Authentic Assessment); (6) The teacher invites students to remember the material being studied (Reflection).
