Abstract

The purpose of this research is to describe the syntax of cooperative learning model of type numbered head together (NHT) and students science process skill toward applying cooperative learning model type Numbered Head Together (NHT) on chemical equilibrium material. This research used One-Group Pretest-Posttest Design with sample of 38 students of XI MIA 3 MAN School of Mojokerto. Methods of data collection in this study is the method of observation and test methods in the form of skills. The results of the study are shown as follows: (1) The implementation of the syntax of cooperative learning model of NHT type obtained an average percentage of 79.98%; 89.15%; and 96.98% with very good category because each phase get percentage ≥ 61%. (2) The skill of science process of students has increased from 21,05% to 81,58%.

Keywords: numbered head together (NHT), science process skills, chemical equilibrium.
