However, in the idea-based class, statements about the significance of learning to see adaptations, out-of-school opportunities for seeing adaptations, and my own fascination with animal adaptations ~see previous discussion! were carefully embedded in the activities. For instance, both classes completed the animal artifacts lab. But in the idea-based class, I more carefully framed the activit y in terms of its potential to expand perception and value. I told the students directly that we were going to practice observing adaptations in actual animal artifacts so that we could learn to see these adaptations in the animals we might encounter outside of class and better appreciate them.
