Piece from Pek Murray Goldberg, which reviews the findings of the Evaluation of Evidence-Based Practices in Online Learning, A Meta-Analysis and Review of Online Learning Studies report from the US Department of Education from 2010.
His conclusions include:
eLearning has been around long enough and studied long enough that we can safely conclude that it is effective for all kinds of knowledge acquisition.
This study makes it clear that the benefits of eLearning are not domain-specific.
eLearning works. It has strengths which create an opportunity to do better than we do now. It is not a replacement for face to face or hands-on training.
The real discussion is about how we apply the strengths and advantages that eLearning brings to an industry that is in desperate need of better (not more) training, more uniform training, and an elevated discussion on what we can do to achieve these.
