Speaking is one of the four English skills that must be mastered by students. Through speaking students can express ideas, opinions, feelings, messages orally and get other information from other students. To help students improve their ability of English speaking, a learning strategy is needed. Which in the use of this strategy there are several internal factors that must be considered, one of which is personality. Personality is divided into two types: extrovert and introvert personality. This study aimed to investigate speaking strategies used by extrovert and introvert students and to identify the most speaking strategies used by extrovert and introvert students at English Education Department in University of Islam Malang. This study used descriptive qualitative method. The participant of this study were the fourth semester students of English Education Study Program at University of Islam Malang who scored "A" in speaking I, II, and III. This research used two models of questionnaire. They were the Eysenck Personality Questionnaire (EPQ) by Eysenck & Barrett (1985) to determine the personality type for each subject and the Strategy Inventory for Language Learning (SILL) by Oxford's (1990) to investigate their speaking strategies. The researcher analyzed the data in the form of percentages. The findings showed that all of high achiever students with extrovert and introvert types use all the same type of strategies: memory strategies, cognitive strategies, compensation strategies, metacognitive strategies, affective strategies and social strategies. But there is a difference in the most speaking strategies used by extrovert and introvert students. The affective strategies (81.6%) and metacognitive strategies (80%) were the most speaking strategies used by extrovert students. Whereas cognitive strategies (81.2%) and metacognitive strategies (80%) were the most speaking strategies used by introvert students. Based on the finding of study, it can be concluded that all of high achiever students with extrovert and introvert types use all the same type of strategies, but the difference is in the most strategies used by extrovert and introvert students. Therefore, it expected to the high achiever students with the extrovert and Introvert type to use all types of strategies, especially affective, cognitive and metacognitive strategies. Then, for teacher are expected to mix several strategies in learning speaking English.
