The Effectiveness of IDEA (Issue, Discussion, Establishment, and Application) Learning Model in Mathematics Concept Understanding

IDEA learning model is one of models developed to instill the mathematical concepts understanding. However,  this model requires further studies to prove its effectiveness. This research aims to determine the effectiveness of the IDEA learning model in embedding mathematical concepts understanding. It is a quantitative study with a quasi-experimental approach. This research was conducted at Malang Islamic University with students majoring Mathematics education study program and in their first academic year as the subjects. Subjects were divided into two group, experimental and control and measured their result using posttest only control group design. There are six instruments consisting six items which are used to measure mathematical concepts understanding.  The results find that H 0 is rejected, while H a is accepted proved by t count (3.132) > t table (1.674). It means there is a significant difference between the of both groups (experimental and control). In addition, the results indicate that the IDEA learning models is affective to assist students in understanding mathematial concepts showed by the higher score of experimental group than control group.
