Blended learning. Blended learning is a student-centered approach that integrates learning experiences in online and face-to-face environments. This article defines blended learning, discusses its history, and provides suggestions for creating an effective blended learning experience.
What is Blended Learning? Blended courses (also known as hybrid or mixed-mode courses) are classes where a portion of the traditional face-to-face instruction is replaced by web-based online learning. How much of the face-to-face instruction must be replaced by online coursework? This question will vary greatly by class, discipline, and learning objectives. The Online Learning Consortium (formerly, the Sloan Consortium, a professional organization dedicated to postsecondary online learning) defines blended learning as a course where 30%-70% of the instruction is delivered online.
