The Brain - is wider than the Sky -For - put them side by side -The one the other will containWith ease - and You - beside -
The Brain is deeper than the sea -For - hold them - Blue to BlueThe one the other will absorb -As Sponges - Buckets - do -
The Brain is just the weight of God -For - Heft them - Pound for PoundAnd they will differ - if they do -As syllable from Sound -

Neuroplasticity: The Adaptive Brain
• Learning experiences literally shape how neurons in the brain connect with one another.
• Connectivity patterns influence how the brain processes new information.

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

Standard Model of ReadingWith an Alphabetic System:
3 Domains to Integrate
! 1. Meaning of Words (Definition)
! 2. Sound Analysis, especially Rhyme
! 3. Visual-Graphic (Letters Spell Words)
! Standard Model: Child Must Integrate TheseDomains to Read Effectively.

Differences in Pathwaysfor Visual Talents in People with Dyslexia
! New Research on Visual Talents in DyslexicScientists< Matt Schneps, Todd Rose, and Kurt Fischer,
in journal Mind, Brain, and Education:P Plus 7 new articles in press or submitted.
! Development of Visual Fields in Dyslexics andNormal Readers< Escher Figures< Geiger & Lettvin, Winner & von Karolyi< Visual Scanning Fields
Distribution of Sensitivity in Visual Field Differs in Dyslexics.
Development: MoreSensitivity in Periphery,Less in Fovea.
Result: Greater Capacityfor Detecting Patternsacross Wide Areas ofVisual Fields, e.g.Astronomers
(But More Distractability)
Task for the Future:Describing These Talents& Limits.
