Application of the constructivism approach to improve students' understanding of multiplication material

This research is motivated by the low ability of students' understanding of concepts in learning mathematics multiplication material. Mathematics learning requires a learning approach that can make students active and student-centered. If mathematics learning is not student-centered, it will lead to boredom which will ultimately make learning unattractive. Therefore, the researcher chose the constructivism approach to improve student learning activities and understanding students' concepts. This study uses classroom action research and was conducted at SDIT Altaftazani. The results of this study, it appears that student learning activities increase. Students become more active in learning, besides that formative test results also show a good level of student understanding of 35.7% is very good, 35.7% is good and 17.8% is sufficient and only 10.8% is still lacking.
