Over and over, I run into this bit of "insight" from constructivists: "Knowledge is constructed by the learner from experience." First, I was beaten over the head with this "insight" in ed school. Now I see it at constructivist sites like this one.
What does it mean? How does it work in practice?
I tried to put it to the test. I decided I want to know something about Tang and Song China. According to constructivists, I need to construct that knowledge from experience. What should I do? I don't have any experience with Tang and Song China. I live now, not in the era of Tang and Song China. Then I hit on a brilliant idea: time travel. I tried cranking up that rusty, old time machine. It didn't work. Now I am trying to construct without experience but with the help of a hat. I am trying to pull the knowledge out of a hat. Ain't working either. I guess I'll just settle for a book and ignore the constructivist piffle.
My conclusion is that either constructivists keep repeating the same nonsense (probably due to a lack of critical thinking ability), or there is something I am not getting. I suspect the former.
Ed guru advice welcome.
On the same site I find this gem:
Radical constructivists do not advocate goals, sequential instruction, aids to learning, or restrictions on content for learners because each learner is unique and educators do not know what the learners need or want to learn.I've got news for these "educators": In my experience, a lot of "learners" don't know what they need either. As for wanting to learn: Forget it!
