This document discusses different principles of effective instructional design for distance education. It explains that communication in distance learning relies more on virtual methods like asynchronous communication rather than synchronous. It emphasizes that learning occurs when the content taught matches the content learned, and skills are demonstrated along with guidance relating specific examples to general principles. Effective demonstration also engages learners and uses relevant media. The document outlines that application of skills is most effective with intrinsic or corrective feedback, and coaching that is later faded out. It stresses integrating a variety of delivery methods and technologies to provide feedback and interaction for students.
