Enhancing problem-solving skills of students through problem solving laboratory model related to dynamic fluid

Abstract

Problem-Solving Skills (PSS) is 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 PSS of students after applied Problem Solving Laboratory (PSL) model on the dynamic fluid topic. The method used was pre-experiment with one group pretest-posttest design. The subject of the research was 30 students of class XI senior high school 27 Bandung. PSS of students was measured with student worksheet and essay test. The result of the study shows that based on the student's answer on the student worksheet there was an increase of PSS during the three meetings related to the topic of dynamic fluida. Average normalized gain of PSS value of 0.60 indicates there was an increase in PSS of students of the medium category. The based result of paired sample t-test values of significance (2-tailed) of 0.000 < 0.05 indicated the use of PSL can enhance PSS of students. Thus, the PSL model can be used to improve PSS of students on the dynamic fluid topic. Finally, PSL could be applicated in other topics of physic and increase another thinking skill.
