Blended learning combines face-to-face instruction with online learning. It balances the effectiveness of online learning with the social benefits of in-person classes. There are various methods of blending, including interactive videoconferencing, online activities, and face-to-face field trips. Blended learning programs provide additional learning materials and allow students to access content anywhere. However, challenges include classroom management across multiple sites and facilitating differentiated instruction and self-paced learning. Effective blended learning requires training facilitators and visiting sites.
