## Application of Connecting Learning Model-Organizing-Reflecting-Extending on The Ordinary Differential Equations Course

Yarman, Ahmad Fauzan, Lufri, Armiati

One of the basic abilities expected by each student in the Ordinary Differential Equations (ODE) course is the understanding of the ODE concept. But the reality shows that students are still weak in understanding the concept. This indication is seen from student learning outcomes that are still relatively...
