Abstract
The research aims to profile the increase of concept mastery as well as problem solving skills after the implementation learning climate change using problem based model. The implementation of learning was conducted in one of secondary school at rural are in Bogor, west java. The research methods used was quasi-experimental with nonrandomized static group pretest postest design. The experimental class consisted of 40 7th grade students who learned science with problem based learning, meanwhile the control class was the same number of student who learned the science using cooperative learning with teams game tournament (TGT). The increase of concept mastery and problem solving skills were measured by using multiple choice-with reason test. The research shows that problem based learning gave better impact to both of concept mastery and problem solving skills of student, as it was shown statistically using Independent Sample T-Test with the sig value 0,000 and 0,001. The good correlation between concept mastery and problem solving skills was also found with sig value 0.03<0.05. This means that the higher concept mastery the better problem solving skills of student.
