<![CDATA[The purpose of this study is to determine the improvement of understanding the concept of learners in the fractional addition of learning by using fraction circle model. The hypothesis proposed is the fraction circle model can improve understanding of the concept of students of class V SD Muhammadiyah 3 Bandar Lampung. This research is Quasi Eksperimen research. The sample used is 2 classes selected by class random technique, that is class V C as experiment class and class V B as control class. Data collection techniques used are the ability to understand conceptual test. The normality test used is the liliefors test to determine whether the samples taken are normal distributed or not and the homogeneity test used in this study is a two-variance similarity test by comparing the largest variance with the smallest variance. Analytical technique used in this research is gain test to see improvement of concept comprehension ability and t-test to see the effect of fraction circle model implementation. The conclusion in this research is fraction circle model can increase understanding of learners concept in fractional learning.]]>
