Blend learning is a formal education program where students learn through both online and in-person instruction, allowing some control over time, place, pace, or path of learning. There are several models of blend learning, including rotation models where students rotate between online and in-person stations, and flex models where material is primarily online but teachers provide on-site support as needed. While blend learning provides flexibility, it also requires reliable technical resources and students and teachers to have sufficient IT literacy and access to technical tools.
