This book is ideal for the professor or instructor who is providing instruction through distance learning. For online instruction to be successful, students cannot just sit and absorb content passively. The online professor/instructor must encourage an engaged learning environment, which is described by the authors as an environment based on constructivist principles and problems-based learning.
One early challenge is to get the students to feel comfortable participating in discussions. The students' level of engagement can be measured partly by looking at the frequency and the quality of the students' interactions. Another challenge is to get students to feel comfortable with the online tools. The book provides at least a dozen 'ice breaker' activities to help students feel confident with discussions and tools. It also recommends that nongraded assignments be used during this initial orientation period.
Different categories of activities are described, including team and peer, reflective, authentic, and learner-led activities. Over a dozen examples of activities are provided for each category. (The authors define reflective activities as those that require the student to share a synthesis of the learning experience and they define authentic activities as those which stimulate an actual situation.) The section on learner-led activities explains how to help learners become successful in preparing and delivering instructional activities, especially with the tasks of defining objectives, defining the type of activity, and planning. Games and simulations are also addressed (but briefly).
Overall, it's a useful book for getting started when you suddenly find yourself having to teach a distance learning course. My only gripe is that I would've liked to have seen a larger section on assessments.
