Preposition Remix: The Musical Way to Master Spatial Skills Turn up the volume on language learning! Developed by certified speech-language pathologist Barbara Fernandes, Preposition Remix is a high-energy, music-themed app designed to help children, English Language Learners (ELL), and individuals with language delays master the "where" in their world. Why Real Photos Matter Unlike abstract cartoons that can be confusing, Preposition Remix uses nearly 200 real-life, high-quality photographs. This concrete visual anchoring helps neurodivergent students and language learners generalize spatial concepts—like under, between, and closest to—from the screen to their everyday environment. Build Your Virtual Band Motivation is the key to progress! As students correctly identify spatial relationships, they earn musical notes to unlock a virtual instrument collection. From guitars to bagpipes, students can tap and play their instruments, turning therapy into a creative jam session. Features for Professionals and Parents: Comprehensive Library: Targets over 20 core prepositions including above, behind, beside, between, under, in front of, inside, closest to, and furthest from. Professional Data Tracking: Automatically logs session dates, targets attempted, and accuracy percentages in a detailed "Report Card". Complete Customization: Toggle individual prepositions on or off to align with specific IEP goals or classroom lessons. Clinical Scaffolding: Adjust feedback settings to include "No Response" for incorrect taps to reduce frustration, or "Written Cues" to support early readers. Multi-Player Support: Manage multiple student profiles on one device, tracking individual progress and instrument collections separately.
