Blended learning combines traditional face-to-face classroom teaching with online instruction. It’s a simple concept but becomes more complex when you consider that there is no one way to blend learning; online and face-to-face instruction can be combined into thousands of blended learning models. Depending on the theme of the course, this approach can take various forms. For example, a subject may be explained by a teacher in front of the students, while knowledge enhancement in the form of supporting topics and activities might be offered in the online environment. Courses can also be compartmentalized, with only certain aspects being presented by the teacher, and the rest of the content being treated as digitally accessible resource/reference material.
