The purpose of the present study was to develop vocabulary teaching courseware (VC), and test its validity for teaching a large number of lexical items. The developed courseware was also expected to foster high vocabulary retention rates. Three experiments were undertaken in this study, and the validity of VC was tested in this study by using TOEFL and TOEIC to measure overall English proficiency of the learners in addition to using locally developed vocabulary tests. In the first experiment, junior high school students used VC and they improved their average listening scores by 40 percentage points. In the second and the third experiments, college students used VC in combination with the listening and reading courseware (LRC). Students' TOEFL and TOEIC scores obtained after using VC indicated that VC was approximately as effective as an additional LRC. Furthermore, the learning with LRC supplemented by VC was found to play a significant role in improving English proficiency of the students whose proficiency levels had been relatively high.
