PENINGKATAN KEMAMPUAN BERFIKIR KREATIF MATEMATIS SISWA MELALUI PENERAPAN MODEL PEMBELAJARAN PROBLEM POSING

This research aimed to know the increasing of student’s mathematical creative thinking skill which was taught by problem posing learning model compared to the conventional learning. The design of this research was pretest posttest control group design. The research population was all students of grade 11th of IPS of SMAN 1 Sumberejo in academic year of 2013/2014 who were distributed into three classes. The sampling was done by purposive sampling technique. The research data were obtained by test of mathematical creative thinking skill. This research concluded that the increasing of student’s mathematical creative thinking skill which was taught by problem posing learning model was higher than the increasing of student’s mathematical creative thinking skill which was taught by conventional learning.
