Efficacy of Spanish Audio-Supported Second Language Vocabulary Learning in a Single Case Study

This study examines the effectiveness of an intervention utilizing audio-supports for bilingual vocabulary learning. Method: Nine target vocabulary words from English story books were selected, which were then pre-recorded in Spanish (L2) as audio files to be used during readings in the home language (L1). This single case study examined the feasibility of audio support in early bilingual vocabulary learning by examining previous literature, and data collected on the gain in vocabulary learning at intervention post-test. Results: It was found that L2 audio support in an L1 reading context can provide an environment for vocabulary gain. It supplied numerous exposures to words and the chance to transfer their literacy skills to the L2, giving a foundation for an emergent bilingual. Discussion: This study highlights the capabilities of technology to further provide opportunities for bilingualism through everyday activities such as reading and utilizing resources already available to educators.
