Abstract
Problem-solving skills are one of the skills needed to prepare the student to face the development of science that can support the world of work. This study aims to determine the improvement of problem-solving skills after applied Problem Solving Laboratory (PSL) model on the dynamic fluid topic. The method used was pre-experiment design with one group pretest-posttest design. The population of this study was students of class XI IPA SMAN 27 Bandung. The sample was chosen by purposive sampling technique amounted 30 people. Problem-solving skills were obtained through an essay test and student activity sheet as supporting instruments. The result of the research shows that the average N-Gain value of 0.60 indicates there is an increase in problem-solving skills of the moderate category. Based on paired sample t-test where tcount (26,2) > ttable (2,04) indicate there is difference improvement in problem-solving skill. Thus, the PSL model can be used as an alternative learning model that can improve the problem-solving skills of a student on the dynamic fluid topic. Finally, PSL can be implemented in other subject learning and could be used to improve another higher order thinking skills
