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…

This study examined the extent to which classroom quality (emotional and instructional climate) moderates the associations between teachers' beliefs about children, self-efficacy, and children's early language gains (receptive and expressive vocabulary). The study employed multilevel modeling with 606 preschool teachers and 2,536 preschool…

Educators recognize children's social competence as an indicator of school readiness. Children's social competence may be promoted prior to kindergarten through parents' discipline. We assessed parent discipline as a predictor of 37 low-income pre-schoolers' social skills over four months. Parents answered open-ended questions about how they would…

The current study aims to examine the way in which teachers' and children's perceptions about their relationships influence children's emergent literacy skills. Participants were 913 children and 114 kindergarten teachers within 72 preschool centers from Greece. The measures used were the Student-Teacher Relationship Scale (STRS), the Child…

This study uses implementation fidelity data from PreK to 1st grade in the Boston Public Schools (BPS) to measure instructional alignment and examine whether stronger alignment is associated with sustained benefits of BPS PreK on children's language, literacy, and math skills through first grade. The study includes N = 498 students (mean age =…

The present study investigated the relationship between teacher-child interaction quality and children's social-emotional and language development. Also considered was the level/status of classroom quality in preschool setting. Classroom Assessment Scoring System Pre-K (CLASS Pre-K), the Devereux Early Childhood Assessment (DECA-P2), and Peabody…

This study aimed to examine the unique and joint contributions of behavioral and emotional self-regulation to key but understudied emergent literacy and early social skills, disentangling sex-differentiated paths. The participants were 231 Portuguese preschoolers (50% boys; M[subscript age] = 59.5 months; SD = 8.5) enrolled in 47 classrooms. In…

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…

With nearly half of all children under age six living in poverty, it is imperative to explore the development of income-related childhood aggression. Here, we specifically examine how family socioeconomic status (SES) relates to children's physical and relational aggression, and how this relation may be moderated by burgeoning social cognition.…

The current study focuses on the cumulative effect on children's early learning outcomes of the quality of teacher-child interactions over multiple years during early childhood. Using propensity score matching to minimize selection bias, we compared the academic outcomes of children who experienced consistently high-quality or consistently…

"Pre-K Mathematics" is a supplemental mathematics program focusing on a range of mathematical concepts to help develop children's informal mathematical knowledge. The "Pre-K Mathematics" program includes teacher-led, small-group mathematics activities that are engaging and hands-on, as well as caregiver-child activities that…

This research examines the influence of educator and child expectations on children's self-regulation, early reading, and vocabulary outcomes over two time points. Thirty educators (15 early childhood educators [ECEs] and 15 teachers) and 149 kindergarten children participated in the research. The educators participated in an expectation ranking…

Research Findings: This study examined how teacher--child conversations unfold during shared book reading in Head Start classrooms as well as the relations between that talk and children's vocabulary learning. Book reading experiences in 27 Head Start classrooms were videotaped and coded for teacher talk, child responses, teacher follow-up…

Research Findings: Children learn most of their vocabulary incidentally, by hearing words used in their environment. This study explored which kinds of presentations of words, without any direct instruction, yielded greater depth of target word knowledge. Changes in 56 kindergartners' depth of knowledge for each of 23 novel target words (N =…

Research Findings: This study examined whether children's outcomes at age 3 were predicted by their experiences in Early Head Start (EHS), focusing on 2 key features of infant and toddler care: (a) stability of care and (b) teacher--child interactions. This study further explored potential interaction effects between stability of care and…
