A longitudinal study on language learning vocabulary in L2 Spanish

[EN] Some learners perform better on listening tests that include visual input instead of only audio (Wagner, 2008) while others have found no difference in the performance of participants in the two test formats (Batty, 2015). These mixed results make it necessary to examine the role of using audio and video in listening comprehension (LC). This study examines the effect of input modality on the learning of new vocabulary with intermediate L2 learners. The study gave four versions of the same text: a baseline in audio format, a baseline in video format, a redundancy-enhanced version in audio format and a redundancy-enhanced version in video format. Three hundred sixty two intermediate learners of Spanish participated in this study over a period of three consecutive semesters. Results about input modality indicated audio or video does not seem to matter in responding correctly to the vocabulary items. However, the redundancy-enhanced version in audio and video formats helped learners to respond correctly to vocabulary items when enrolled in face2face-blended courses compared to online-hybrid courses.
