Online learning has become the norm rather than the exception for many of today's students. Instructorsare more willing to explore online learning options, students are enrolling in record numbers and colleges, as well as many K-12 institutions,are offering more online courses. As educators, we have more tools than ever to ensure online course success, but just as with atraditional class, we must continue to place emphasis on good pedagogy. To achieve good pedagogy, online teaching takes additionaltime and a restructuring of course content by the instructor. Student issues include coping strategies, ease of navigation, skills requiredto complete the course, availability of online resources, feedback from the instructor, and collaborative, interactive learning opportunities.Principles of interactive online learning are new to many, and this book provides a forum for interactive online learning researchwhile also including ideas that enhance both the practical and theoretical aspects of interactive online learning.
