Training Model of Troubleshooting Mathematics Materials of LCM And GCD Through PBL

摘要

The purpose of this research is to investigate the 4th grade of elementary school students in term of solving their skill of LCM and GCD in math in the form of problem solving through model problem based learning (PBL). To support the research, the research procedure used a classroom action research procedure with two cycles. In the first cycle, the students who involved the class were 15 students from 21 students (71.42%) while in the cycle II, there were 19 students from 21 students (90.47%). The result showed that by implementing problem-based learning model on LCM and GCD materials, students was trained in term of mathematical problem solving skills. The implementation was also to train teachers' skills in learning mathematics using problem-based learning model.
