Abstract

This study aims to improve science learning outcomes of students with the application of cooperative learning model Numbered Heads Together at SMPN 2 Sinaboi VIIB class in the academic year 2015/2016. Which was conducted in March 2016. The subjects were students of SMPN 2 Sinaboi VIIB grade school year 2015/2016 with a total of 25 people (11 students and 14 female students).
