What approach does blended learning primarily utilize?

Blended learning primarily utilizes a mix of online and in-person learning, which is why this option is correct. This approach combines the benefits of traditional face-to-face classroom instruction with the flexibility and accessibility of online educational resources. Students can engage with materials and complete assignments online at their own pace while still having the opportunity for direct interaction with teachers and peers during in-person sessions. This hybrid model caters to different learning styles and can enhance overall student engagement and understanding.

The other choices do not accurately capture the essence of blended learning. Offline learning only focuses on face-to-face interactions without incorporating online elements, while teacher-centered lectures emphasize a more traditional, one-dimensional teaching style without the integration of technology. A standardized curriculum across all platforms overlooks the personalized and adaptive nature that blended learning strives for, where curricula can be tailored to fit both online resources and classroom activities.
