The purpose of this study is to explore the effects on improving English listening skills as well as the other areas of English such as reading, speaking and writing skills through drilling dictogloss for university students in Korea. The study consisted of experimentation conducted over twelve weeks with fifty-eight university freshmen students. The participants of the study were divided into two groups: a control group and an experimental group. The control group performed spot dictation, while the experimental group received instruction via dictogloss summaries. Pre- and post-listening tests as well as reading, speaking and writing tests were used to examine results. The experimental group received dictogloss practices after listening the text given, and the other group, the control group, received spot dictation practices after listening to the same text that the experimental group used. The results of the experiment show that the experimental group trained with dictogloss did show a significant difference in the listening skills test and also in the reading, speaking, and writing skills tests. This implies that dictogloss is effective for students to improve not only listening skills but also reading, speaking, and writing skills.
