Blended learning is a pedagogical approach and mode of delivery that intentionally integrates face-to-face instructional methods with online, technology-mediated learning activities. As a research field and academic concept, it investigates the design, implementation, and evaluation of learning experiences that strategically combine these modalities to optimize student engagement, flexibility, and learning outcomes. Its significance lies in its potential to leverage the unique affordances of both environments, fostering innovative pedagogical strategies and expanding access to education.
