The Effect of Problem-Based Learning Assisted Concept Map to Problem-Solving Ability and Critical Thinking Ability

Abstract

This research aims to: determine the effect of model problem based learning model concept map on the ability to solve problems and critical thinking physics students of SMA Negeri 3 Padangsidimpuan. This research is a quasi experimental research with two group pretest posttest design. The population of this research is all students of class X SMA Negeri 3 Padangsidimpuan. Samples were taken 2 classes are determined by random cluster sampling technique, that is experiment class applied problem based learning model with concept map and control class applied conventional learning. The instrument that used in this research is the problem-solving ability instrument in essay form as much as 5 questions and critical thinking ability instrument in essay form 5 questions which has been declared valid by expert team. From the result of the research, it can be concluded that the problem solving ability of physics of students that is taught by the problem based learning model assisted concept map is better than the students who are taught by conventional learning and the critical thinking ability of physics students who are taught by the problem based learning model assisted concept map is better than the students with conventional learning. There is a positive influence of problem based learning model assisted concept map to the ability of problem solving and ability of critical thinking of physics students.
