The Effect of Problem Based Learning (PBL) Model and Self Regulated Learning (SRL) toward Physics Problem Solving Ability (PSA) of Students at Senior High School

This study aimed to analyze whether student’s Problem Solving Ability that learned using Problem Based Learning Model better than conventional learning, to analyze whether student’s Problem Solving Ability who have above average of Self Regulated Learning better then students who have below the average Self Regulated Learning, and to analyze interaction between Problem Based Learning and conventional learning using Self Regulated Learning in improving students' Problem Solving Ability. This research is a quasi-experimental design with two group pretest posttest design. The study population were all students of class XI SMAN 13 Medan academic year 2015/2016 and the sample was grade XI IPA 3 and 5 selected by simple random sampling. The data were analyzed by two ways ANOVA. The results showed that: (1) student’s Problem Solving Ability that learned using Problem Based Learning Model was better than the conventional learning, (2) Problem Solving Ability groups of students who have above average Self Regulated Learning is better than the students who have below average Self Regulated Learning, and (3) there was an interaction between Problem Based Learning Model and conventional learning using Self Regulated Learning in influencing students' Problem Solving Ability.
