The students' mathematical critical and creative thinking ability in double-loop problem solving learning

The purpose of the study is to examine whether or not there is an increase in students' critical and creative thinking skills using double-loop problem solving (DLPS) learning compared to ordinary learning. The method of this research is a quantitative method, with a pretest-posttest design. The population of this study involved all class VIII students in one of the Cimahi Junior High Schools, while the sample selected by two classes VIII consisted of the experimental class namely students who received DLPS learning and control classes namely students who received ordinary learning. The technique of processing N-gain scores using IBM-24 SPSS software. The results of this study are 1) increasing the ability of mathematical creative thinking of students who use DLPS learning better than students who use ordinary learning and 2) increasing the ability of mathematical critical thinking students who use DLPS learning is no better than students who use ordinary learning. In general it can be concluded that DLPS learning can improve students 'creative mathematical thinking skills but have not been able to improve students' mathematical critical thinking skills, especially in junior high school.
