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.
A hybrid is the offspring of genetically dissimilar parents or stock, especially the offspring produced by breeding plant or animals of different varieties, species or races, something of mixed origin or composition, such as a word whose elements are derived from different languages.
