AI-Powered Personalized Remediation System with Multi-Engine Practice Generation

[02Tirtha]

🚀 AI-Powered Personalized Remediation System

Overview

This PR introduces a comprehensive Personalized Remediation System that automatically generates concept-specific practice questions for students based on their incorrect answers in assessments.

After a Diagnostic Test or Level Worksheet evaluation, the system identifies incorrect responses, detects the underlying learning concept, and generates 5 personalized practice questions to help students strengthen their understanding of that concept.

The implementation combines deterministic generation with AI-powered content generation to ensure remediation is always available, even when external AI services are unavailable.

⚙️ Workflow

1. Student submits a Diagnostic Test or Level Worksheet.
2. Evaluation Engine identifies incorrect answers.
3. Remediation Service creates a remediation ledger.
4. Original questions are mapped to learning concepts.
5. Smart Router selects the best generation engine:
   • Numeric Engine
   • Matrix Engine
   • Gemini AI
6. If AI generation fails, Blueprint Engine generates deterministic practice questions.
7. Five personalized practice questions are stored and displayed in the Remediation Notes page.

🧠 Generation Engines

Numeric Engine

Generates arithmetic and calculation-based practice questions such as addition, subtraction, multiplication, division, fractions, measurements, place value, and comparisons.

Matrix Engine

Generates classification, matching, odd-one-out, pattern recognition, and visual reasoning exercises.

Gemini AI

Handles complex language-based, tracing, clock, tally, geometry, and other advanced educational question types.

Blueprint Engine

Provides deterministic concept-based question generation and serves as a reliable fallback whenever AI generation is unavailable.
