Over the past few decades, there has been extensive debate as to whether humans represent number abstractly and, if so, whether perceptual features of a set such as cumulative surface area or contour length are extracted more readily than number from the external world. Here we show that 7-month-old infants are sensitive to smaller ratio changes…

Policymakers have turned to teacher evaluation as one way to ensure accountability for school reform. In most evaluation systems, the emphasis focuses on the external: test scores, observations of classroom practices, rubric based assessments, student feedback, evaluation, and student work. While these activities have a place in professional…

When nonrandom treatments occur across sites, within-site matching (WM) is often desirable. This approach, however, can significantly reduce treatment group sample size and exclude substantively important subgroups. To limit these drawbacks, we extend a matching approach developed by Stuart and Rubin to a multisite study. We demonstrate the…

This article reviewed a method for increasing teachers' use of behavior-specific praise, which is especially important for students with emotional and behavioral disabilities. The use of performance feedback has been researched fairly extensively and has yielded positive outcomes when compared with other forms of consultation. This article…

Mathematical listening is an important aspect of mathematical communication. Yet there are relatively few examinations of this phenomenon. Further, existing studies of students' mathematical listening come from observational data, lacking the student perspective. This study examined student replies to an open-response question regarding what…

Background: This study examined the sustainability of New Moves, a school-based program aimed at decreasing weight-related problems in adolescent girls. The National Cancer Institute recognizes New Moves as a research-tested intervention program that produced positive behavioral and psychosocial outcomes. Methods: Ten schools participated in the…

Background: The importance of professional development training for individuals tasked with providing quality early child care is widely accepted. However, research assessing the impact of specific, long-term professional development programs on changes in caregiver behavior is largely absent, as is research about the processes and mechanisms of…

Research Findings: The purpose of the current study was to evaluate the structural validity of scores on a measure of global classroom quality, the Classroom Assessment Scoring System (CLASS K-3; Pianta, La Paro, & Hamre, 2008). Using observational data from a sample of 417 kindergarten classrooms from the southern and mid-Atlantic regions of…

Various educational mandates, including the Individuals with Disabilities Education Act (IDEA) and No Child Left Behind (NCLB), and educational approaches, such as Response to Intervention (RTI) and Positive Behavior Supports (PBS), require use of objective data to inform decision making for academics and behavior. However, some traditional…

This study examined the effects of lesson study on participants' classroom observations and perceptions of lesson effectiveness, by investigating the focus of their observations during a mathematics lesson and their ratings of the lesson's effectiveness, both preceding and subsequent to the lesson study experience. Prior to the lesson study,…

One of the outcomes of the New Zealand early childhood curriculum, "Te Whariki", is "working theories". Prior research on this concept has primarily utilised sociocultural theoretical underpinnings and neglected Piagetian constructivist theories. This paper explores ways the Piagetian concepts of equilibrium and disequilibrium…

Collaboration between participants with different roles, but equal status, is the aim in action research. In this project we experienced problems establishing equality between the participants. The research question discussed in this paper is: "How did the researcher experience that the use of narratives affected the level of equality between…

Teacher evaluation has emerged as a potentially powerful policy lever in state and federal debates about how to improve public education. The role of student test scores and "value-added" measures in teacher evaluation has generated intense public controversy, but other approaches to evaluation including especially classroom observations…

The significance of the problem being investigated is conditioned by the need of introduction of considerable amendments to academic discipline content with the objective of ensuring effective education process and professional competencies development level increase of bachelors in machine engineering necessary in their professional activities…

This study examined level of engagement with Disney Princess media/products as it relates to gender-stereotypical behavior, body esteem (i.e. body image), and prosocial behavior during early childhood. Participants consisted of 198 children (M[subscript age] = 58 months), who were tested at two time points (approximately 1 year apart). Data…
