Application of Problem Based Learning and Learning Motivation in improving Student Learning Outcomes in Economics Subjects: A Quasi-Experimental Research

The research aims to find out: (1) the influence of the Problem Based Learning model on the learning outcome of the pupil; (2) the impact of the motivation on the learners’ learning outcomes; (3) the influences of the interaction of the Problem Based Learning models with the motivations on the learner’s learning output. The study uses a quantitative approach of a quasi-experimental type with a post-test only-of-non-equivalent control group design. Sample on this study, namely students of class XI IIS 1 as an experimental class and students of Class XI II 3 as a control class. The research instrument uses motivation assessment and a double-choice test that already meets the quality of the instrument. Data analysis in this study uses N-Gain and the Two-Way Anova test. The results of the study show that (1) the Problem Based Learning model has an influence on the learning outcome of the student, this has been demonstrated by comparing the average value of the experimental class higher than the control class, (2) the learning motivation has an impact on the student’s learning outcomes, and (3) there is an impact of the interaction of the problem-based learning model with the motivation on the learners’ learning output. So, if you want to improve the student’s learning outcomes, then teachers can use the Problem Based Learning model as an alternative and strengthen the motivation of the student during the learning process.
