Blended learning can be defined as the organic integration of thoughtfully selected and complementary face-to-face and online approaches and technologies.

The authors argue that this new learning environment necessitates significant role adjustments for instructors and generates a need to understand the aspects of teaching presence required of deep and meaningful learning outcomes.
