Implementation of Modified Problem Based Learning (PBL) in Improving Learning Outcomes of Physics Vocational School for Optical Materials

Abstract

The purpose of research on the implementation of Problem Based Learning (PBL) can improve students' physics learning outcomes in terms of knowledge and skills. Classroom Action Research was conducted in two cycles, the research subject was class X APHP 03 with 35 students. Method data collection uses tests for knowledge and skills aspects through observation. Data analysis is descriptive qualitative for aspects of knowledge by percentage of students' mastery level classically and aspects of skills through scoring observation sheets. Learning outcomes from cycle I and cycle II have increased in the knowledge by 17.14%. Aspects of student skills increase in the indicators of systematic presentation, mastery of the material and pronunciation at the time of presentation, so that the implementation of Problem Based Learning (PBL) can improve student learning outcomes.
