PENERAPAN MODEL PEMBELAJARAN KOOPERATIF TIPE NUMBERED HEADS TOGETHER (NHT) UNTUK MENINGKATKAN HASIL BELAJAR MATEMATIKA SISWA KELAS III SD NEGERI 21 PEKANBARU

Abstract

Abstract : The problem this research is the low mathematics learning outcomes of students, with an average grade 62.28. While the value of a minimum completeness criteria (KKM) IPS is 70. Among the students numbering 35 people only 14 students who reach KKM with classical completeness 40%. This study is a Classroom Action Research (CAR) conducted aims to improve mathematics learning outcomes third grade students of SD State 21 Pekanbaru to implement cooperative learning model type Numbered Head Together. Formulation of the problem: Is the implementation of cooperative learning model Numbered Head Together mode can improve mathematics learning outcomes third grade students of SD Negeri 21 Pekanbaru. The research was conducted on 6 April 2015 through to 23 April 2015 with 3 cycles. The subjects were the third grade students of SD State 21 Pekanbaru totaling 35 which is used as a data source. Data collection instruments in this thesis is the teacher and student activity sheets and learning outcomes. This thesis presents the results of learning derived from the value of daily tests before treatment with an average of 62.28, an increase in the first cycle with the average being 71.71. In the second cycle increased by an average of 76.71 and an increase in the third cycle with an average of 83.41.
