Examines constructivism in online learning, suggesting that part of the cause of the gap that exists between educational theorists and science instructors about how subjects can be taught appears to be due to different beliefs about what it is possible to learn. Illustrates a scientist's approach through examples of an online course designed by…

Proposes a model for transforming equivalency in education from a unit of measurement focused on time in the classroom to one focused on learner achievement. While allowing time and location to vary across courses and academic programs, the Capabilities Based Educational Equivalency (CBEE) Units model permits the valid comparison of student…

Outlines steps instructors must undertake to prepare for constructivist activities. Presents two categories of constructivist activity supported by the Web. Students may construct advanced mental models by: cooperating with peers, and/or connecting personal conceptions with expert conceptions. Online environments that allow learners to perform…
