The aim of this paper is to explore the effects of listening strategy used in the instruction of college students while undergoing the TOEIC listening test. It will also discuss relevant and effective learning strategies that can be applied in the classroom. The participants in this study were 70 college students participating in an intensive TOEIC course for a period of four weeks at a college in Gumi. The students were divided into two groups: control(n=33) and experimental (n=37). Three sets of TOEIC test scores and two different questionnaires were used in the testing process. The major results of this study were as follows. First, the students tended to use cognitive strategies rather than metacognative strategies during the TOEIC test. Secondly, the students applied commonly used strategies after the new listening methods were introduced and they considered the strategies in a positive way. Thirdly, the use of different listening strategies resulted in improved listening comprehension scores. Lastly, the listening strategies used did not show a statistical effect on the students listening proficiency. These findings demonstrate that providing effective strategies such as cognitive and metacognitive strategies which were proved as an useful method in listening acquisition will be a good way for students to improve their listening skills.
