The Problem

-67% of fourth-grade children do not read at proficient level

- 33% of fourth-grade children cannot read at even a basic level

Interventions

- Proliferation of commercially available emergent literacy instructional tools

- Few have evidence of efficacy or effectiveness

- “Mixed results” across efficacy studies question robustness of interventions

Effectiveness/Scale-Up

Are there malleable factors that could be the target of intervention?

What does intervention look like?

How potent was the change under specified, controlled conditions?

How robust was the change under real-world conditions?

Scalable Solutions

“Scale-up is not a euphemism for the uncritical diffusion of interventions ….

To the contrary, scale-up research is doomed to fail if practitioners and policymakers expect it to generate absolute solutions …

A context-based approach to scale-up research provides the evidence that educators need to select the interventions that are most likely to work in specific settings.”

(McDonald, 2006, p. 21)

Contextualizing What Works

Observations

Design/Feasibility

Efficacy

Effectiveness/Scale-Up

Are there malleable factors that could be the target of intervention?

What does intervention look like?

How potent was the change under specified, controlled conditions?

How robust was the change under real-world conditions?

Do these factors vary by child or context?

Is it specifically suited for certain children?

Do these effects vary by child or context?

Does it work when used at- scale for the children and in the settings where it is best suited?

Attention

Implications

(a) The relation of book reading and literacy outcomes is diminished in children with SLI

(b) Adult behaviors may be important to the learning of children with weak attentional skills

(c) Pieces of experiences may meet some, but not all, of a child’s learning needs

Explicit Print Instruction

“ Here is our title. Let’s read the words- “Giggle Giggle Quack.” Giggle begins with the letter G. This is the letter G… Sam, can you come up and show me the letter G on the page?”

Explicit Print Instruction • Utterances related to words, letters, book and

print, and print meaning.

Note: This model Include the covariates of age, fall print knowledge, and study condition and environmental support for print. Additional covariates considered and found to be non-significant include gender, child attendance, maternal educational attainment, teacher years of experience, program type, teacher educational attainment

Explicit print instruction (Z-Score)

Explicit print instruction varies in its association to children’s spring print knowledge as a function of classroom quality

Classroom Quality

Explicit print instruction (Z-Score)

The association between explicit print instruction and children’s spring print knowledge varies as a function of children’s attentional abilities

Implications

a) Explicit print instruction was robust to variation in language skill

b) Explicit print instruction appears to be especially suited for children with weak attention skills

c) Explicit print instruction appears robust to lower classroom quality

26

Discussion

a) Value of asking “what works for whom and under what conditions”

b) Value of identifying proximal moderators to intervention

27

Future Directionsa) Read It Again modifications and

evaluation in needs-based rural Appalachian preschool programs

b) Read It Again replication in early childhood special education settings
