The current study examined the contexts in which a preschool teacher professional development intervention was more versus less effective in improving student outcomes. We used a fixed intercept, random coefficient (FIRC) modeling approach to explore the contextual characteristics inside and outside school walls that predicted differential…

Back-and-forth conversations with adults are critical for developing children's language, and, therefore, an important part of the early childhood classroom learning environment; however, the specific nature of teacher feedback, one component of teacher-child conversations, on child language has not been widely studied. This article examined…

Teachers in early childhood education (ECE) settings are central to providing children with high-quality experiences that promote both early development and long-term well-being; unfortunately, rates of teacher turnover are high in ECE settings. There are strong theoretical reasons to assume turnover is negatively linked with children's academic…

The Lesson Study is a professional development model that places teachers at the center of practice and is used in the professional development of teachers who are currently in teacher training or currently in service. In Turkey, the professional development of teachers from various branches is also supported by using this model. However, no…

Prior research shows that short-term effects from preschool may disappear, but little research has considered which environmental conditions might sustain academic advantages from preschool into elementary school. Using secondary data from two preschool experiments, we investigate whether features of elementary schools, particularly advanced…

We examined the relations between teachers' use of comments during book reading sessions in preschool classrooms and the vocabulary growth of children with low and moderately low language ability. Using data from a larger randomized controlled trial, we analyzed comments defined as utterances that give, explain, expand, or define. Comments were…

Research Findings: Effects on children's school readiness were evaluated for 2 interventions focused on improving teacher-student interactions (coursework, coaching) implemented sequentially across 2 years. Teachers from public prekindergarten programs in 10 locations were assigned randomly to treatment or control conditions in each year.…

The 3-year Pennsylvania Dyslexia Screening and Early Literacy Intervention Pilot Program (Pilot) began in 2015-16 (Year 1) with the kindergarten class of 2015-16 (Cohort 1). In 2016-17 (Year 2), the Pilot was implemented with Cohort 1 students, now in first grade, and a second cohort of kindergarteners (Cohort 2). A third cohort will be added in…
