This study aims to analyze whether Advance Organizer learning model and
Concrete-Pictorial-Abstract (CPA) approach has an effect on students' ability in
mathematical analogy. post-test only control design is used in this research, and the
population are all students of class VIII SMP Negeri 2 Sokaraja. The Side random
cluster is determined as the sampling technique which obtained two sample classes,
class VIII A as a control class with direct learning and class VIII B as an experimental
class with Advance Organizer learning with Concrete-Pictorial-Abstract (CPA)
approach. The results show that the mathematical analogy ability of students who
joined the Advance Organizer learning with Concrete-Pictorial-Abstract (CPA)
approach is better than the mathematical analogy of the students who join direct
learning, or in other words, Advance Organizer learning with Concrete-Pictorial-
Abstract CPA) affects students' ability in mathematical analogy at the eight grade of
SMP Negeri 2 Sokaraja.
