This document provides an overview of blended learning models. It defines blended learning and distinguishes it from general classroom technology use. It then describes the main models of blended learning: Rotation model, Flex model, A La Carte model, and Enriched Virtual model. The Rotation model involves students rotating between online and offline activities. The Flex model uses online learning as the backbone with flexible face-to-face support. The A La Carte model involves students taking entirely online courses alongside their regular classes. The Enriched Virtual model includes required face-to-face sessions with optional remote online work. Examples are provided to illustrate how different learning scenarios fit within these models.
