More theorizing about theory! Observations from reading Harasim--
Learning theories of any kind seem to be mostly about -change. That is, the theory is an explanation of why beings (animals and plants too sometimes) change their behavior when they learn something.
Behaviorism is concerned with change in behavior. You can observe that. Tell a student, "You'll get a good grade if you study this material and take the quiz," and you can see that the student puts down the phone and takes the quiz. Behavior changed, and we can make assumptions about why.
But cognitivism is concerned with changes in cognition-- how we think. So we observe how students improve, say, in their ability to remember a poem after they hear it set to music. (I can still SING but not recite Frost's "Stopping by Woods on a Snowy Evening" 45 years after Sister Evarista taught us to sing it to a tune she'd written.) And we can make assumptions about why music helps people memorize.
The change either way is due to some intervention from the outside, whether it's a stimulus or just access (like a library) or an assignment.
Can it be an "intervention" from the inside, like something inside me makes me want to change? Like I break my ankle and I want to learn about bones?
