Abstract: The aim of this research is to determine the influence of learning models using scientific approach with the students achievement viewed from the student activities. The learning models compared are TGT, NHT, and PBL. This research is a quasi experimental research. The population is all students of eight grade of state Junior High School in Bojonegoro Regency in the academic year of 2014/2015. The samples are 300 students. The methods of data collection are documentation, questionaire, and test. The technique of data analysis used is two ways analysis of variance with unbalanced cells. Based on the result of data analysis, it can be concluded that : (1) The students’ learning achievement by using cooperative learning model TGT, NHT, and PBL with the scientific approach had the same learning achievement. (2) The students’ learning achievement of students with high learning activity had better learning achievement than students with medium and low learning activity, while students with medium and low learning activity had the same result. (3) For category high, medium, and low learning activities, the learning achievement of students who were given by cooperative learning model TGT, NHT, and PBL with scientific approach had the same result. (4.a) For category cooperative learning model TGT and PBL with scientific approach, the students’ learning achievement with high, medium and low learning activities had the same learning achievement. (4.b) For category cooperative learning model NHT with scientific approach the students’ learning achievement with high learning activity had better learning achievement than medium and low learning activities. For students having medium and low learning activities had the same learning achievement.Keywords: Team Games Tournament (TGT), Numbered Head Together (NHT), Problem Based Learning (PBL), Learning Activity
