The term blended learning is generally applied to the practice of using both online and in-person learning experiences when teaching students. In a blended-learning course, for example, students might attend a class taught by a teacher in a traditional classroom setting, while also independently completing online components of the course outside of the classroom. In this case, in-class time may be either replaced or supplemented by online learning experiences, and students would learn about the same topics online as they do in class—i.e., the online and in-person learning experiences would parallel and complement one another.

Also called hybrid learning and mixed-mode learning, blended-learning experiences may vary widely in design and execution from school to school. For example, blended learning may be provided in an existing school by only a few teachers or it may be the dominant learning-delivery model around which a school’s academic program is designed. Online learning may be a minor component part of a classroom-based course, or video-recorded lectures, live video and text chats, and other digitally enabled learning activities may be a student’s primary instructional interactions with a teacher. In some cases, students may work independently on online lessons, projects, and assignments at home or elsewhere, only periodically meeting with teachers to review their learning progress, discuss their work, ask questions, or receive assistance with difficult concepts. In other cases, students may spend their entire day in a traditional school building, but they will spend more time working online and independently than they do receiving instruction from a teacher. Again, the potential variations are numerous.
