To identify the features of extratextual questions that help 3-year-olds learn unfamiliar words during shared book reading, two experiments explored the impact of cognitive demand level, placement, and an approximation to scaffolding.…

Rigorous research provides information that will allow ECE (Early Childhood Educator) programs to select interventions that have a scientifically based track record of effectiveness in increasing teachers' skills and teaching quality. This paper shares implementation and impact results as well as the lessons learned in conducting an evaluation of…
