The study aims to determine the effectiveness of mathematics learning achievement for students who are subject to the Problem Based Learning model assisted by CD Learning and CD Interactive as well as Conventional learning models on flat-build material. The population in this study were seventh grade students of SMP Negeri 223 Jakarta Timur in the academic year 2017/2018. By using selected cluster random sampling techniques VII 3 as the control class, VII 6 and VII 7 respectively as the

... ntal class PBL models assisted CD learning and assisted PBL models CD Interactive. Data were obtained by documentation and tests, then analyzed by Normality, Homogeneity, One-way Variant Analysis (ANOVA), Two-party and One-party Similarity Test. The results showed that there were significant differences between mathematics learning achievement of students who were taught by learning using PBL models assisted by CD Interactive, PBL models assisted by CD learning and conventional learning. Learning achievement of students who get learning using CD Interactive media is better than students who get conventional learning. Likewise, the learning achievements of students who get learning using CD Learning, media are better than students who get conventional learning. In addition, there were no significant differences between the mathematics learning outcomes of students who were taught using PBL models assisted by CD Interactive and students using PBL models assisted by CD Learning.
