THE EFFECT OF HARD WORK CHARACTER AND PROBLEM BASED LEARNING MODEL TOWARD PHYSICS LEARNING OUTCOMES STUDENTS AT SMPN 4 SEI SUKA

This research objectives to know 1 the difference in physics learning outcomes of students using problem based learning model with direct instructional model 2 the difference in physics learning outcomes of students who have high hard work character with students who have low hard work character and 3 the interaction between hard work character and problem based learning model toward physics learning outcomes Population in this research is all of students of SMPN 4 Sei Suka class VIII Academic Year 2013 2014 Samples in this research are class VIII 1 and VIII 3 Samples technique is cluster random sampling This study used quasi experiment methods According to research variables there are two types of data collected in this research namely 1 hard work data of students and 2 physics learning outcomes data of student Hard work data of students collected using questionnaires while data student learning outcomes collected by providing test questions to students Technique of analyzing data by using ANAVA two ways with the significant level of 0 05 The result of research shown that 1 there is difference in physics learning outcomes of students using problem based learning model with direct instructional model 2 there is difference in physics learning outcomes of students who have high hard work character with students who have low hard work character and 3 there is interaction between hard work character and problem based learning model toward physics learning outcomes Scheffe test results showed that the group of students who have high hard work taught with problem based learning models obtained learning outcomes 85 88 is higher than other groups of students either group of students who have low hard work taught with direct instructional model 78 06 group of students who have low hard work taught problem based learning model 75 67 or group of students who have high hard work taught with direct instructional model 74 29 While the results of Scheffe test between groups of students who have high hard work and low hard work are taught with direct instructional model indicate that the group of students who have high hard work obtain learning outcomes 74 29 lower than the group of students who have low hard work 78 06 although both are taught with direct instructional model.
