What does the concept of "blended learning" refer to?

Blended learning refers to an educational approach that combines traditional face-to-face instruction with online learning activities. This method leverages the strengths of both in-person teaching and digital resources, allowing for a more flexible and effective learning experience. By incorporating online elements, learners can benefit from the advantages of personalized pacing, access to a wider range of resources, and the ability to revisit materials at their convenience.

In contrast, the other options suggest limited or single-method approaches that would not encompass the integrated nature of blended learning. For example, excluding online components entirely would not allow the enriching aspects that digital tools provide, while a strictly digital environment misses the interpersonal dynamics present in face-to-face learning. Likewise, relying solely on textbooks denies students the interactive and multimodal experiences that blended learning offers. Thus, the correct answer reflects the comprehensive nature of blending multiple instructional methods to enhance student engagement and learning outcomes.
