This study aims to determine the effect of instructional models and interpersonal intelligence on social studies learning outcomes. The study was conducted in the department of primary education of Halu Oleo University, Kendari, Indonesia. 112 students of primary education at Halu Oleo University in the fourth semester are the population of this study. This research is quasi-experiment with treatment by level. Classes were chosen randomly with 38 students in both controlling and experiment class. As much as 22 students with high and low interpersonal intelligence from both classes are the sample of this research. While the data of learning outcome are gained by multiple choice test, interpersonal intelligence data are taken by questionnaire. The data are then analyzed by ANOVA and Tukey test. The results show that there are differences in student learning outcomes between those taught with reciprocal instruction models and direct instruction models. There is an interaction between instruction models and interpersonal intelligence. The Tukey test results show that reciprocal instruction models have a better effect on students who have high interpersonal intelligence. However, the direct instruction model has a better effect on students who have low interpersonal intelligence.
