Brain: Most Complex Object in Universe
       The Brain - is wider than the Sky -
       For - put them side by side -
       The one the other will contain
       With ease - and You - beside -
                                             Minister of
       The Brain is deeper than the sea -
       For - hold them - Blue to Blue        Education in a
       The one the other will absorb -       European
       As Sponges - Buckets - do -

       The Brain is just the weight of God -
       For - Heft them - Pound for Pound
       And they will differ - if they do -

Neuroplasticity:
               The Adaptive Brain
  • Learning experiences literally shape how
  neurons in the brain connect with one another.
Learning a New Skill Requires Growing a New Neural Network.
  • Connectivity patterns influence how the brain
  processes new information.

Need for Research Schools:
Research and Development for Schools



! Research and development are commonplace in
  most industries and fields.
 <   Cosmetics, Chemicals, Agriculture....
 <   Traffic Safety: National Data Base
 <   We Need Research and Development in Education!

! Educational theory should be tested by its
  consequences in action (Dewey, 1896, 1938).

! Research informs practice, and practice informs
  research.
Prime Example Is Sesame Street:
        Research on Practice Every Day



 ! Ongoing Assessment of Practice

 ! Tool for Improving Learning and
   Teaching.

Beyond the Fad to Build a Field < Building a Network of Research Schools
  • 4. Neuroplasticity: The Adaptive Brain • Learning experiences literally shape how neurons in the brain connect with one another. Learning a New Skill Requires Growing a New Neural Network. • Connectivity patterns influence how the brain processes new information. Dendrites Cell body Axon OECD, 2007
  • 5. But School Is [Students Fill in]. BORING! C & M Suàrez-Orozco Treating Students as Disembodied Brains into Which We Pump Knowledge! Better Model: Active Intelligence – Grasping & Building with the Mind XWorldPlugInBrainBucketVTS_05_1.VOB.lnk
  • 6. Illegitimate Claims from Neuroscience XWorldPlugInBrainBucketVTS_05_1.VOB.lnk (Command Line) ! Learning Involves Filling Our Brains with Knowledge – NOT. ! There Are Left-Brain and Right-Brain People – NOT. ! We Only Use Half (or Less) of Our Brains – NOT. ! Boys & Girls Have Fundamentally Different Brains – NOT.
  • 7. Response to Seeing a Word Flashed What Other Regions Participate in Network for Seeing a Word? dog º Visual Area

  • 10. Need for Research Schools: Research and Development for Schools ! Research and development are commonplace in most industries and fields. < Cosmetics, Chemicals, Agriculture.... < Traffic Safety: National Data Base < We Need Research and Development in Education! ! Educational theory should be tested by its consequences in action (Dewey, 1896, 1938). ! Research informs practice, and practice informs research.
  • 11. Prime Example Is Sesame Street: Research on Practice Every Day ! Ongoing Assessment of Practice ! Tool for Improving Learning and Teaching. !
