Abstract
This research is a Classroom Action Research (CAR) which is conducted in three cycles, each cycle is held 2 x meetings, and each cycle is carried out 5 x 40 minutes. The purpose of this study was to improve mathematical communication skills and learning activities of class VIII students of Tarogong Kaler 2 Junior High School in the material of Flat-Side Building through efforts to improve actions taken from cycle to cycle. The subjects in this study were eighth-grade students of Tarogong Kaler 2 Junior High School 2 semester of the academic year 2018 - 2019 which numbered 34 people. Data collection techniques in classroom action research are observations of students mathematics learning activities, the value of learning outcomes, obtained from the students final tests conducted at the end of each cycle, interviews, and documentation. The data in this study used a mathematical communication test each cycle and analyzed using quantitative and qualitative. For quantitative analysis, descriptive statistics are used to describe mathematical communication skills in solving mathematical communication problems after learning, which consist of mean, range, maximum value and minimum value and the percentage of mastery learning obtained students in each cycle. Data from observations of student mathematics learning activities and interviews were analyzed qualitatively. The results of this study reveal that mathematical communication skills and learning activities of class VIII students of Tarogong Kaler 2 Junior High School in the Flat-Build Space material experienced an increase from cycle to cycle through efforts to improve actions taken.
