The Use of Portfolio in the Implementation of Problem Based Learning Model to Improve Student Learning Outcomes

Abstract The purpose of this study is to describe the use of portfolio in the implementation of problem-based learning to improve learning outcomes of Natural Sciences. This study is a qualitative research namely Classroom Action Research. The focus of this research is the application of problem-based learning and learning outcomes. The subjects of study were teachers and students of class V with the number of students 20 people, consisting of 9 boys and 11 girls. Moreover, data collecting technique used is observation, testing, and documentation. The data analysis used is qualitative and quantitative. The results showed an increase in activity and student learning outcomes. It is concluded that teaching and learning activities of teachers and students in Natural Sciences with the use of portfolio in the application of problem-based learning improve student learning outcomes.
