Previous studies on visually enhanced input have examined how input enhancement impacts L2 vocabulary learning. However, they have mostly conducted a short-term investigation into the effectiveness of input enhancement through one or two immediate test scores after a treatment. Filling this gap in the literature, the present study looks into effects of visual input enhancement on L2 learner's vocabulary learning based on a series of prolonged post tests. A total of 143 university students, consisting of four different groups (no enhancement and no repetition, no enhancement and repetition, enhancement and no repetition, enhancement and repetition), participated in the study. The data for this study were collected over one semester through four post tests after a treatment, and the results show that a repeated provision of the input enhancement has more positive effect on vocabulary learning than the provision of no enhancement or one-shot enhancement.
