This document outlines a proposed study that would examine the effects of supplementary aural exercises via podcasts on students' acquisition of Spanish prepositions. It describes the research questions, methodology, participants, study design, and conclusions. The study would involve undergraduate Spanish students being divided into experimental and control groups, with the experimental groups listening to podcasts and completing written activities in addition to their regular coursework. Both groups would take pre- and post-tests involving cloze activities to measure their knowledge of prepositions. The document discusses challenges with implementing the study and limitations that may arise.
