The purpose was to determine whether teaching science vocabulary using information text could improve low-income preschoolers' word knowledge, conceptual development, and content knowledge in the life sciences. Teachers in 17…

In this quasi-experimental study, we assessed the promise of Word Generation, a research-based academic vocabulary program, on improving the reading achievement outcomes of struggling sixth-grade readers in an after-school small group instructional setting. After 34 hours of academic vocabulary instruction, we compared the performance of a…

We conducted a randomized field trial to test an academic vocabulary intervention designed to bolster the language and literacy skills of linguistically diverse sixth-grade students (N = 2,082; n = 1,469 from a home where English is not the primary language), many demonstrating low achievement, enrolled in 14 urban middle schools. The 20-week…

Purpose: The purpose of this study was to determine the effectiveness of a conversation intervention including 500 min of linguistically and cognitively complex talk on the expressive vocabulary growth of prekindergarten children. Method: Children (N = 73) were randomly assigned to control or a 10-week experimental intervention condition. Twice…
