People learn and grow though cooperative problem solving. Another benefit of the process is that it results in understanding and empathy for other's situation. To often collaboration is the last choice in problem solving instead of the first choice. One watches the situation heat up, like a pot of water on the stove. For a long time the water molecules bounce around in their own spheres.
Nothing seems to happen.
Then all of a sudden the molecules align themselves together in a pattern and the water boils. The molecules join in the rise and fall to the surface. The internal organization theory states that separate bodies of cells with different purposes will, when the stimulus is right, join together in a single purpose. Vision is a good example of this principle. There are about thirty different systems identified in the brain that work separately on vision problems.
