摘要：We implemented an Extension-led language and literacy training and coaching intervention targeting preschool teachers and children in low-income communities in Nevada. Participation in the intervention had a positive influence on the language and literacy instruction skills of preschool teachers and language and literacy skills of children. Analysis of 40 preschool classrooms and 199 preschoolers over 3 years of data collection identified improvements in general classroom environments and teachers' language and literacy practices. Preschoolers demonstrated improvements in alphabet knowledge, comprehension, phonological awareness, vocabulary, and oral language. Extension professionals elsewhere may use a similar approach to positively affect the achievement gap of at-risk children.
