Gj. Whitehurst et al., A PICTURE BOOK READING INTERVENTION IN DAY-CARE AND HOME FOR CHILDRENFROM LOW-INCOME FAMILIES, Developmental psychology, 30(5), 1994, pp. 679-689
The effects of an interactive book reading program were assessed with
children from low-income families who attended subsidized day-care cen
ters in New York. The children entered the program with language devel
opment in standard English vocabulary and expression that was about 10
months behind chronological age on standardized tests. Children were
pretested and assigned randomly within classrooms to 1 of 3 conditions
: (a) a school plus home condition in which the children were read to
by their teachers and their parents, (b) a school condition in which c
hildren were read to only by teachers, and (c) a control condition in
which children engaged in play activities under the supervision of the
ir teachers. Training of adult readers was based on a self-instruction
al video. The intervention lasted for 6 weeks, at which point children
were posttested on several standardized measures of language ability
that had been used as pretests. These assessments were repeated at a 6
-month follow-up. Educationally and statistically significant effects
of the reading intervention were obtained at posttest and follow-up on
measures of expressive vocabulary.
