The purpose of this study was to determine the ability of the student mathematic connection by using the realistic of mathematic educational approach is better than conventional learning. This research used quasi-experimental design with two-group design, they were pretest-posttest. The sample of this study was taken from random class, that is taken 2 classes with total number 54 students. Class VII-1 as an experimental class which taught by using realistic mathematic approach that consists of 27 students, class VII-2 as control class which taught by using conventional learning that consists of 27 students. The instrument of this research used the essay test and observation. The result was analyzed by using t-test. After the learning is done, the data descriptions were collected on pres-test and post-test to determine students' mathematic connection ability during mathematic learning. The result showed that the ability of the students' mathematic connection by using the realistic of mathematic educational approach is better than conventional learning. Furthermore, based on the observation of student activity in the learning process by using the realistic of mathematic educational approach is very positive and they became more active than before.
