THE INCREASING OF STUDENTS’ MATHEMATICAL COMMUNICATION ABILITY THROUGH SOMATIC, AUDITORY, VISUAL, AND INTELLECTUAL (SAVI) APPROACH AT SMAN 1 PERBAUNGAN

The purpose of this research was to know whether the increasing of students’ mathematical communication ability taught by Somatic, Auditory, Visual, and Intellectual (SAVI) approach is higher than taught by ordinary mathematics learning. The type of this research is quasi experiment. The population of this research was all students at SMA Negeri 1 Perbaungan with the sample was two classes which each class consists of 30 students, XI A as experimental class taught by SAVI approach and XI B as control class taught by ordinary mathematics learning. The sample was taken by cluster random sampling. The Instruments used to collect the data were essay test of mathematical communication ability that given in the end of learning either in experimental class and control class and questionnaire of student responses. The instrument has been declared eligible content validity and reliability coefficient. Data were analyzed by t-test. Based on the analysis results obtained that the increasing of students’ mathematical communication ability taught by Somatic, Auditory, Visual, and Intellectual (SAVI) approach was higher than taught by ordinary mathematics learning. From the data analysis of posttest score by using t-test with significance level  = 0.05 obtained that tcalculated = 4.731 and ttable =
1.671. It means that tcalculated > ttable then H0 is rejected and Ha is accepted. This study was supported with the result of questionnaire of student response which is classified in good category. Thus, researcher suggests applying SAVI approach to increase students’ mathematical communication ability.
