"ABSTRACTThe goal of this research is to improve student knowledge about the shape of the earth and the environment awareness. This research was implemented to students of VII F SMP Negeri 6 Sukabumi in their first semester of academic year 2013/2014. This is a classroom action research conducted in two cycles in which each cycle consisted of two methods. The research was a collaborative effort of a team consisting of one researcher, one teacher model and two observers. The number of students of VII F is 42; consisting of 20 boys and 22 girls. Through validity test of student knowledge about the surface of the earth, 30 questions are obtained out of the 40 questions on the first cycle. Based on the result of data analysis on student knowledge about the shape of the earth in the first and second cycles, we obtained respectively 71,43% and 80,95. Based on the result of data analysis of environmental awareness in the first and second cycle, we learned that high awareness levels respectively 45,24% and 76,19%. This means that in the first cycle, the intended high awareness was not achieved because it was only < 50% (the success criterion). Meanwhile in the second cycle the figure was > 50%. So the success criterion are achieved. Based on these data it can be concluded that the learning management of using jigsaw cooperative learning method and guided inquiry can improve student knowledge about the shape of the earth and the environmental awareness."
