Problem based learning models based on science technology engineering and mathematics for developing student character

This study aims to determine the implementation of Science, Technology, Engineering, and Mathematics (STEM) based Problem Based Learning (PBL) model, identifying increased knowledge achievement, character development, and skill enhancement. This research uses Quasi Experiment method while design uses one group pretest-posttest design. The instrument consists of an essay test for measuring the knowledge achievement and an observation sheet for measuring skills and character outcomes. Implementation PBL model based STEM on Impulse and Momentum materials, assisted by Student Worksheet, can improve knowledge achievement (cognitive) and skill (psychomotor), and also can develop the character of discipline, curiosity, communicative, and cooperation.
