Receptive and expressive vocabulary skills in preschoolers are predictors of later literacy skills. Research shows that children from low socioeconomic status (SES) backgrounds are generally behind their peers in the area of vocabulary skills when they enter school. Many preschool programs now focus on increasing these skills through shared book reading interventions. The purpose of the current research is to study the efficacy of a specific shared book reading intervention, dialogic reading, with low-income preschoolers in the area of vocabulary development. The search yielded 10 intervention studies that utilized dialogic reading strategies in interventions with the target population. Studies yielded mixed results but generally found that dialogic reading intervention does have significant positive effects on receptive and expressive vocabulary. Limitations and implications for practice are discussed.
