Blended learning is a combination of some face-to-face teaching and some online teaching. It is a great way for teachers to bring online components into the forefront, rather than just using digital materials as supplemental (often at home) course materials.
Blended learning has a huge advantage – it doesn’t prescribe that particular activities must be online or in person. There isn’t a particular percentage of teaching and learning that has to happen in the classroom or not.
You can tailor it to your needs, and do some experimentation. It is so flexible, and can be something different for each teacher, each class, or each student. One class may lean heavily on the online component and another may not, depending on the availability and appropriateness of materials available
