Pengaruh Model Problem Based Learning Terhadap Kemampuan Komunikasi Matematis Siswa

This study aims to determine the effect of a problem-based learning model on student’s mathematical communication skills. The population was all students of grade VIII SMP Negeri 19 Bandarlampung odd semester in the academic year 2019/2020 that were distributed into ten classes. The research samples were all students of grade VIII E and VIII F which were selected through a purposive sampling technique. The posttest only controls group design was used as the design of this research. The research data analysis using U-test at a significant level α = 0.05, students’ communication skills with the problem-based learning model are significantly higher than students’ communication skills with conventional learning.
