Offline AI Math Tutor for Early Learners (Ages 5–9) — Adaptive, Multilingual, Low-Resource EdTech Solution | AIMS KTT Hackathon | Siltanu Alemu # 🧠 AI Math Tutor for Early Learners (Offline, Multilingual, Adaptive) ## Overview This project presents an offline AI-powered math tutor designed for children aged 5–9 in low-resource environments. The system delivers foundational numeracy instruction through a combination of visual representations, audio prompts, and interactive feedback, while adapting dynamically to each learner’s progress. The tutor operates entirely offline, runs on CPU-only devices, and supports multilingual and code-switched input, making it suitable for real-world deployment in settings with limited connectivity and shared devices. --- ## Problem Context Across many low-resource settings, children complete early primary education without mastering basic numeracy skills. By ages 8–9, many learners still struggle with: - number recognition - simple arithmetic operations - problem-solving skills The core challenge is not access to schooling, but the lack of **personalized instruction**, compounded by language transitions (e.g., moving from Kinyarwanda to English). --- ## Solution The system delivers a complete end-to-end tutoring experience: - presents math problems using visuals and audio - accepts responses via text or speech (optional ASR) - detects and adapts to the child’s language - provides immediate feedback and guided correction - repeats questions when needed to reinforce learning - adapts difficulty using learner performance The focus is on **teaching**, not just evaluation. --- ## Core Capabilities ### 1. Adaptive Learning (Knowledge Tracing) A Bayesian Knowledge Tracing (BKT) model tracks mastery across skills: - counting - number sense - addition - subtraction - multiplication - division - word problems The system updates learner state after each interaction and selects the next item accordingly. --- ### 2. Multilingual & Code-Switched Interaction The tutor supports: …
