Development of Mathematical Learning Materials with Constructivism Approach Using Mobile Learning System

This research aims to produce learning materials learning math with constructivism approach through mobile learning system. This research is research development. Development methods used follow the 4-D model of the stage define, stage design, develop and disseminate stages stage. On the research focused at the third stage i.e. develop. The subjects in this study are students of mathematics education courses the University Bung Hatta 2015 forces totaling 26 people. The results obtained from studies on stage develop this is learning materials have been produced using mathematical constructivism approach through Mobile Learning System a valid and practical. Overall excess materials this is student accessible online through the browser the browser on a Laptop, Smartphone, or Computer with the address of www. yusriwahyuni. xyz and also can be displayed offline after learning materials in this Download. Students can measure the level of his own understanding towards the subject matter by way of doing evaluation and see the results of the evaluation that they are working on. In addition students can also repeat or continue his studies back at home independently and more fun.
