The purpose of this research is to investigate the different of learning outcomes through MOMBI between paired groups of student and peers tutor groups of student. This research was conducted in the department of physics education at 2^nd semester students of Manado State University. The type of research used is experimental research. The instrument used was a pretest question of 3 items and postest questions of 4 items. From the results of the study obtained an average value of pretest is 31.76 while the average value of the postest is 70.48. In testing the hypothesis with a value of α = 0.05, obtained t_count = 6.18 and t_table = 2.0639 so because t_count > t_table can be concluded that are differences in learning outcome trough MOMBI treatment based on paired groups of student and peers tutor groups of student on the application of multiple representations in vector addition.
