This paper aims to discuss the applicability of the approach known as Content and Language Integrated Learning (CLIL) to preschool. CLIL is a form of language immersion where the learners’ second language represents the medium of classroom instruction. The novel idea is to use music and related multimedia contents in order to foster biand multi-lingualism by addressing children aged from 3 to 6. In this context, we will propose a computer-supported education environment which adopts IEEE 1599, an XML format originally designed for the representation and synchronization of music and media contents. Its multi-layer approach represents a valid tool to support multiple interconnected descriptions, thus fostering abilities and reinforcement techniques typical of CLIL. Finally, we will present an example aiming to test the efficacy of the proposed approach in real-world use cases.
