The challenge of providing authentic experiences and interactions for fostering oral proficiency and motivation in foreign languages is an opportunity for innovation in educational technology and instructional design. Although several recent innovations have received the attention of scholars, empirical investigation and validation is often lacking, as is the case with voice over instant messaging (VoIM). The goal of this study was to empirically test the effectiveness of VoIM for enhancing students' oral English proficiency and learning motivation. Different types of online discussions were examined-unstructured, structured without the facilitation of English teaching assistants (ETAs) and structured with the facilitation of ETAs. A pre-test and post-test quasiexperimental design was employed to achieve this goal. The participants, 90 students enrolled in three sections of a freshman English course at a large university in Asia, participated in eight VoIM discussions in addition to their regular coursework. The results provide empirical support for the importance of structured discussions and the facilitation of ETAs in improving both oral English proficiency and learning motivation. These findings highlight the role of facilitation in VoIM discussions, and recommend prompt feedback, modelling and encouragement for fostering oral proficiency and learning motivation in foreign language classes. Based on the results of this study, recommendations for future research are provided.
Practitioner NotesWhat is already known about this topic • Authentic language experiences are crucial for fostering oral proficiency and motivation in English language learning. • Computer-mediated communication (CMC), in both synchronous and asynchronous forms, offer opportunities for learners to enhance their English reading, writing, listening and speaking skills in an environment that overcomes the limits of distance.• Social constructivism offers language educators many useful strategies for fostering language proficiency and student motivation, including peer collaboration, scaffolding of learning activities, and peer and instructor facilitation.What this paper adds• This paper examines a relatively new technology, Voice over Instant Messaging (VoIM), as an instructional tool for fostering oral proficiency (one of the most difficult areas of language acquisition) and student motivation (which is critical for all areas of language learning). • The data demonstrates that with the facilitation of English teaching assistants, structured online discussions were successful in fostering student oral proficiency and English learning motivation (as compared with structured online discussions with peer facilitation or unstructured online discussions), contributing to the growing body of literature on the use of technology to enhance English language learning. • The quasi-experimental design adopted for this research is particularly robust, especially in terms of the internal validity of the findings, providing clear and substantiated insights...
