Early childhood researchers from across the U.S. came together to form the Early Learning Network (ELN) in 2016 with the mission to identify policies and practices that narrow opportunity gaps and help children maintain early learning success. Early Learning Network teams share what they have learned--and what it means for early childhood education practice and policy--in a series of research briefs. The briefs summarize impact areas that have potential to positively contribute to young children's learning and development, including key takeaways and action steps for practice, policy and research. This brief focuses on the impact area of classroom experiences and learning opportunities. Targeted, positive classroom experiences, including one-on-one language exchanges, teacher-student interactions, student-student interactions, exposure to content-rich instruction and modeling/scaffolding, are associated with students' skills. Classroom learning opportunities, such as large group activities, and strategies, including behavior management and routine cues, are not consistently positively associated with student outcomes.
