Question 3

Narrative 10-2 -Daycare Center - Part II
Ken studies literacy and is particularly concerned about children who lag in reading readiness.He has developed a reading readiness program that can easily be implemented by day care providers in group settings,and has selected two day cares in demographically similar neighborhoods.Ken begins by giving a reading readiness to all of the three- and four-year-olds in both of the day cares.He then implements his intervention at one daycare but not the other,and after the intervention is complete,he administers the reading readiness test again to both groups of children.
