Ymeyer -- the programmes tested in Follow Through were put into practice in American public schools, which accept children at age 5 at the youngest. Kindergarten is the youngest grade at which you can start in an American elementary school. (In the 60s and early 70s, many children didn't even go to Kindergarten, but started at age 6 in 1st Grade.) Headstart (preschool for disadvantaged children) is not part of the public school system though it is administered by the Dept of Education.
Zig Engelmann taught his own twin sons to read and do maths at a young age and filmed them. Is this what you saw on Youtube? His role in Follow Through was not to teach, but to design his DI programme and train teachers to implement it, and persuade schools to adopt it.
You keep on bagging away with that term 'evidence-based' but have yet to provide any evidence that 4 year olds are suitable candidates for phonics lessons.
Your child's complete lack of progress in reading sounds extraordinary, btw. Maybe it's your experience with him that is blinding you to the fact that most children can and do learn in several different ways. It is obvious from your posts that you do not understand what cognitive skills involve or their importance in learning to read, do maths etc. Cognitive development is 100% necessary and 100% complementary to the phonics approach.
'In the last decade technological advances in brain imaging have allowed cognitive researchers to incorporate neural processes into their analysis of behavior. This increased resolution has helped researchers to refine theories in many areas of cognition and education. For example, the Dual Route Hypothesis assumed that reading is composed of two distinct processes: visual word recognition and a phonological process. Traditional behavioral experiments have failed to confirm or invalidate this hypothesis. Neuroscience evidence has helped us realize that there is an interaction and contribution of both pathways (Booth, et. al, 2004) and that an understanding of these processes may help in the development of effective interventions (Shaywitz, et. al, 2004).'

Feenie -- To suggest that SP or any phonics instruction (as in Jolly Phonics, etc) is not formal is disingenuous. It is teacher led by design, and therefore formal. It is formal whether you do it at 3, or 4, or 5 or later. SP involves teacher-led and teacher-directed activity for however long each day it is done.
Some neuro-biological and neuro-psychological studies on cognitive development:
'The rapid development of child neuropsychology
'The concept of developing the brain: a new natural science for learning and education'
'The cerebellum and language; the story so far'
'Cerebellar disorders in childhood: cognitive problems' 'Neuropsychological studies reveal a relation of dyslexia and attention deficit disorder with cerebellar functions.'
'Role of the cerebellum in cognitive and behavioural control: scientific basis and investigation models'
'Cognitive functions, their development and modern diagnostic methods'
An adequate field test of a programme prior to its inclusion in Follow Through would have included actual training of teachers and implementation on a classroom setting, with stated goals and clear methods outlined as to method of teaching and also measurement of the effects of that particular method. This would have prevented some of the errors in classification of methods from the outset and perhaps even prevented some programmes from being included.
