Not the baby and the blanket kind—the kind Kathy Sierra talks about in this post. The learner's mind wants, and likely needs, to have something to figure out, not to have all the answers laid out for it. From her post:
In learning, the more you fill things in and hold the learner's hand, the less their brain will engage. If they don't need to fire a single neuron to walk through the tutorial, lesson, lecture, etc., they're getting a shallow, surface-level, non-memorable exposure of "covered" material, but... what's the point? Obviously this doesn't mean you just never tell them anything period. This is about graduated hints, mental teasing, cognitive treasure hunts, sparking curiosity, etc. Things that engage the brain.
This makes so much sense to me. And when I think about it, my best learning experiences have been taught through this, to use her fabulous phrase, "cognitive seduction."
