4OUR YOUNGEST CITIZENS WILL SURPRISE US
- Infants, Toddlers, and preschoolers can learn
more than we ever thought possible - From birth to age 3 the brains of children are
rapidly forming connections between neural cells - The quality and degree of connections between
neural cells are established through the the
quality of interactions the child has with
adults, other children, and the environment - Infants before the age of 6 months can perceive
and express all sounds of all languages spoken on
the planet
5OUR YOUNGEST CITIZENS WILL SURPRISE US
- Depending on the environment, vocabulary
development accelerates rapidly during the second
year of life. - Under the right circumstances, most 18 month olds
(on average) learn 9 new words a day, every day,
throughout the preschool years - By 3 years of age the child can speak in full
sentences
6The Role of the Environment and Early Experience
on Language Development
- Language development requires an interplay
between genes, biology, and environmental factors - Poverty and disadvantage reduce the quantity and
quality of interactions with language - Limited language interactions in the home
environment place children at severe risk for
school failure, particularly in reading - Cultural influences every aspect of human
development and must be considered in the design
and implementation of any program
7Environmental Influences
- By kindergarten a child from disadvantage
typically has twice the vocabulary as a youngster
born into poverty - The typical 5-year-old from an urban environment
and disadvantaged home enters kindergarten at the
5th percentile in vocabulary - By age 16 advantaged children have four times the
vocabulary as children born into poverty
8Major Sources of Reading Failure
- Socioeconomic Factors Poverty
- Biological Factors Genetics and Neurobiology
- Instructional Factors Predominate
9How Do Children Learn to Read?The Influence of
Early Language and Literacy Experiences
- Differences in exposure to words over one year
can predict substantial difficulties in oral
language and reading development
- Children in Professional Families 11 million
- Children in Working-class Families 6 million
- Children in Welfare Families 3 million

14WHAT DO KIDS NEED TO KNOW TO READ?
15WHAT DO KIDS NEED TO KNOW TO READ FOR MEANING?
Accurate and fluent word reading skills
Oral language skills (vocabulary, linguistic
comprehension)
Extent of conceptual and factual knowledge
Knowledge and skill in use of cognitive
strategies to improve comprehension or repair it
when it breaks down.
Reasoning and inferential skills
Motivation to understand and interest in task and
materials

18Early Intervention is Possible
-
- Risk characteristics present in Preschool,
Kindergarten and G1 - Print awareness, Letter knowledge, letter-sound
knowledge, phonological awareness, oral language
development, vocabulary, background knowledge - Assess all children and INTERVENE
19Early Intervention is Clearly Effective
- Prevention studies commonly show that 70- 90 of
at risk children (bottom 20) in K- 2 can learn
to read in average range

23The consensus view of most important
instructional features for interventions
Instructional interactions and Interventions are
more effective when they
- Provide systematic and explicit instruction on
whatever component skills are deficient phonemic
awareness, phonics, fluency, vocabulary, reading
comprehension strategies - Provide a significant increase in intensity of
instruction - Provide ample opportunities for guided practice
of new skills - Provide appropriate levels of scaffolding as
children learn to apply new skills
24Reading stimulates general cognitive growth
particularly verbal skills

29LEARNING, LITERACY AND THE ROLE OF THE MEDIA
SOME SUGGESTIONS
- Base everything you do on converging scientific
evidence on how children learn, why some children
have a tough time, and what can be done about
that - Avoid at all costs the development of media for
children on the basis of untested philosophies,
assumptions, anecdotes, and lousy research - Try to avoid getting caught up in either-or
debates they are stupid and not productive - Make sure you evaluate the effectiveness of any
products through the application of the
appropriate research methods and designs
