The purpose of this study is to investigate the effects of two different types of vocabulary activities on Korean EFL learners’ vocabulary learning and perceptions. The participants of the study were 30 Korean middle school students in Seoul, and they were divided into two groups (typography and web-based authoring). The former employed the word meaning and spelling image association technique and the latter used a multimedia vocabulary authoring tool for 42 target words. The major findings of the study are as follows: (1) Both the typography and the web-based vocabulary authoring groups showed significant improvement on the posttest of vocabulary test, which indicated the equal effectiveness of the two vocabulary activities; (2) with respect to different English proficiency levels, the low-level group showed much higher improvement of the mean difference between pre and post tests than the higher group; and (3) the participants’ perceptions turned out to be more positive when they participated in creating English word spelling image than authoring multimedia vocabulary learning materials. The results suggest the beneficial effects of active student involvement in the vocabulary learning process. Pedagogical and practical suggestions are made on the effective teaching of English vocabulary in Korean classroom settings.

The purpose of this study is to investigate the effects of using and authoring web-based vocabulary learning tasks on Korean EFL learners' vocabulary acquisition. The subjects of the study were seventy-seven EFL college students in Korea. They were divided into three groups: a traditional control group, and two experimental groups using and authoring the web-based vocabulary tasks, respectively. The major results of the study were as follows: first, the two experimental groups performed significantly better on the vocabulary recognition and use posttest than the control group did. This result indicates that both the use of the web-based tasks and the participation of students in authoring the web-based tasks are more effective in vocabulary acquisition than the use of traditional vocabulary learning methods. Second, both the experimental groups performed significantly better on the delayed posttest than the control group did. This result provides evidence that using and authoring web-based vocabulary tasks are effective in helping students retain newly acquired words in the long-term memory. Third, the learners' responses of the two experimental groups prove to be positive with respect to the use of the web-based task authoring tools in vocabulary learning. Based on these results, some pedagogical suggestions should be made on the effective use of the web-based task authoring tools in Korean English classroom settings.
