The study investigated the impact of a purpose-designed mobile assisted language learning program on Korean college freshmen EFL vocabulary skills, as well as their perceptions of the m-learning program, of the value of its component tasks, and of its impact on various skill areas. A single-section comparison group (n = 13) completed the standard college program, while participants in a two-section treatment group (n = 32) experienced a ten-week-long program that included a variety of tasks and activities using videotaped speeches by prominent native English speakers, accessed via YouTube. Pre-test/post-tests results revealed a statistically significant improvement in vocabulary skills for the treatment but not for the comparison group. Questionnaire data showed 1) positive perceptions of the m-learning program, with treatment participants identifying Looking up words/information as the most useful, effective, easy, and satisfying task and giving lowest marks across quality categories to the only task completed individually, as opposed to working with partners or in teams; and 2) belief in the program’s “helpfulness,” particularly in the areas of vocabulary, listening, and speaking skills. Individual interview responses also indicated value associated with the convenience and motivational aspects of the form and material in the program, respectively, as well as corroborating its positive impact on vocabulary. |
