Incidental vocabulary learning through viewing television

Previous research investigating L2 incidental vocabulary learning from video has primarily focused on short videos from genres that may be conducive to vocabulary learning. The research provides evidence that L2 incidental vocabulary learning can occur through video. However, it is uncertain whether viewing episodes of full-length television programs can contribute to incidental learning. This study investigated the effects of viewing 7+ hours of television on incidental vocabulary learning as well as the effects of the frequency and range. One-hundred and eighty-seven Japanese university students viewed ten 42-minute episodes of an American drama. Two vocabulary tests at differing sensitivities were used in a pre- and post-test design measuring receptive knowledge of the form-meaning connection of 60 word-families. The results indicated that (a) viewing television contributed to significant gains in vocabulary knowledge and (b) there was a positive relationship between frequency of occurrence and vocabulary learning. Pedagogical implications are discussed in detail.
