PENINGKATAN KEMAMPUAN PEMECAHAN MASALAH MAHASISWA PGSD UNIVERSITAS RIAU PADA MATERI PECAHAN DENGAN PENDEKATAN MODEL METHOD

Abstract

This research is motivated by the number of students who have difficulty in performing arithmetic operations on the fractional material in the context of the story of a story that strengthens the students to be able to solve these problems.
