PENINGKATAN KEDISIPLINAN DAN HASIL BELAJAR MATEMATIKA DENGAN MODEL PEMBELAJARAN KOOPERATIF TIPE NUMBERED HEAD TOGETHER

Abstract

The purpose of this research was to improve the discipline and  learning outcomes in mathematics of students of class VII A SMP N I Kretek using learning type Numbered Head Together. The subjects of this research was students of class VII A SMP N I Kretek  totaling 26 students. The object of this research was discipline and mathematic learning outcomes. The results showed that after application of cooperative learning model to Numbered Head Together, discipline and learning Mathematics has increased. This is indicated by an increase in the average yield percentage discipline of each student's learning cycle, namely the pre-cycle percentage discipline of 73,31%, in the first cycle of 79,08% and 87,37% for the second cycle. In addition the average mathematics student learning outcomes is increased in pre-cycle for 66,73 increased to 74,36 in the first cycle and second cycle becomes 79,64. As for mastery learning increased from pre-cycle by 57,70% to 61,54% in the first cycle and became 80,77% in the second cycle. Given the cooperative learning model Numbered Head Together can increase discipline and Mathematics student learning outcomes, teachers are expected to implement the learning model in the learning process.
