Rise 360: Animated, Scenario-Based E-Learning Design

I've always thought story-based learning was far more effective than reading a list of facts. Not just for the workplace but also K-12. I wish K-12 textbooks would utilize the approach. So, why don't they? If training and learning were more effective via story, then why don't corporations and educators use it more? My guess is that it's more expensive ... the instructional designers and writers have to think more!
