The objective of this study is to improve communicative English skills of Japanese high school EFL learners utilizing computer-assisted learning materials. In order to survey the effects of long-term instruction, a whole-year experimental teaching was conducted with a group of high school students over the course of a year. During the experiment, the participants learned English in a CALL room after school as their club activities in addition to regular classes-primarily with computer-assisted learning material for listening English based on the Three-step Auditory Comprehension Approach. For the purpose of evaluating its effectiveness, the scores of GTEC for STUDENTS before and after the additional instruction were compared. Significant differences were observed between the rise of the average scores of the students who attended the instruction and those who did not. Although the study was not conducted under laboratory conditions, it can be considered that learners' communicative skills can be successfully improved by providing appropriate materials in an effective way.
