Ancient Wisdom Rediscovered

I have to say that even on a Friday night, this "constructivist" stuff is fascinating! But my answer to the question is that the technology is not directly driving the changes; indeed, the changes in education are more a reflection of how concepts of quantum physics and esoteric psychology are slowly infiltrating the mainstream. Like it or not, the mind is a mental construct of the ego, fashioned largely from the unconscious, and is the product of one's culture, familial circumstances and surroundings, as well as subconscious belief systems. The world "out there" appears to be a collective illusion, which is quite a challenge to the western concept of reality and learning. One can find as good an explanation of all of this in ancient Hindu and Buddhist texts, and quantum physics seems to be "discovering" some very ancient wisdom.
From a scientific standpoint, we know that all visual date goes through seven synapses prior to arriving at the processing centers of the brain. In each of those synapses, we have discovered chemical neurotransmitters that contain every single one of our experiences and memories. Thus all "knowledge" is filtered through our prior experience! This is a very challenging fact for those of us who aspire to teach critical thinking. The constructivist understanding of learning seems to reflect many of these discoveries, albeit in a still very conventional context.
The problem with quantum physics is it challenges our conventional notions of reality, the ones you and I use to drive to the grocery store, for instance, so completely that most other disciplines simply do not know what to do with it. But in the realm of technology, these discoveries are not constrained by philosophical blinders, and thus change is rapidly coming. But e are not far from computer chip brain implants, and we already have programs and techniques that can "rewire" the brain to lessen learning disabilities, end propensities toward violence, release traumatic memories, etc., etc. Quantum physics drives the changes in technology, and new theories of learning are scrambling to catch up. Constructivism would appear to be poised to be the winner. This quote from The Institute for Inquiry on Constructivist Learning Theory sums things up nicely: "Learning is not understanding the "true" nature of things, nor is it (as Plato suggested) remembering dimly perceived perfect ideas, but rather a personal and social construction of meaning out of the bewildering array of sensations which have no order or structure besides the explanations (and I stress the plural) which we fabricate for them."
Wow! Now give that some thought. We fabricate a personal and social construction of meaning. And if this strikes you as crap masquerading as intelligent observation, consider this: your hand moves prior to your mind thinking of the movement, and your mind then projects backward in time to create the sense that it thought of it first! This is called subjective referral in space. Now, other than the rather interesting question of who or what is actually moving your hand, we have the very challenging idea that even the things we take for granted, movement, for instance, may be a fabrication of the mind. And we may all be particpating in the same collective fabrication. Where does knowledge and learning and thinking all fit into this conception of the mind and the illusion of physical reality? Don't ask me.
