The representation of numerical and non-numerical ordered sequences was investigated in children from preschool to grade 3. The child's conception of how sequence items map onto a spatial scale was tested using the Number-to-Position task (Siegler & Opfer, 2003) and new variants of the task designed to probe the representation of the alphabet…

The relation between skill in simple addition and subtraction and more general math achievement in elementary school is well established but not understood. Both the intrinsic importance of skill in simple calculation for math and the influence of conceptual knowledge and cognitive factors (working memory, processing speed, oral language) on…

Introduction: In recent years, brief experimental analysis (BEA) has emerged as an approach to identify the most effective instructional strategies needed to increase reading fluency before applying an intervention for extended periods of time. The purpose of this study was to investigate the effects of adding performance feedback to skill-based…

Although studies investigating the validity of positive affectivity and negative affectivity in children have been supportive, investigations of changes in the structure of affect across childhood have demonstrated mixed results. The current study used confirmatory factor analytic techniques to test one-factor, two-factor correlated, and…

We investigated whether induced mood influenced the social information processing steps of goal clarification and response decision in 480 1st-3rd graders, and in more selected groups of low accepted-aggressive (n = 39), average accepted-nonaggressive (n = 103), and high accepted-nonaggressive children (n = 68). Children participated in two…

Although the transparency of a writing system is hypothesized to systematically influence the cognitive skills associated with reading development, results of cross-language investigations are inconsistent and usually do not address this issue in a developmental context. We therefore investigated the cognitive dynamics of reading fluency of…

This article begins to unravel the question, "What curricular materials work best under what kinds of conditions?" The authors address this question from the point of view of teachers and their ability to implement mathematics curricula that place varying demands and provide varying levels of support for their learning. Specifically, the…

This Study evaluated the effectiveness of the Arabic language multimedia products existing in Malaysian markets. For the purpose of careful investigation, this research has applied blended models of the most trusted instructional design based on the field-tested theories of the most outspoken educational psychologists such as Mayer (2002), Keller…

This paper explores one school's implementation of a locally developed curriculum reform known as "Math-Science Investigations". At one level, it offers an account of a reform told from the perspective of a classroom teacher and her 3rd- and 4th-graders. At another level, it reconstructs their experience to explore the understandings of the…

Science centers can engage students; accommodate different learning styles and individual interests; help students become independent and confident learners; and encourage social skills among students. In this article, the author worked with third-grade students as they completed activities at learning centers during a week-long unit on simple…

In this article, the author discusses her investigations into the connection between the values of Swedish society and Swedish classroom practices by way of the early childhood special education system. She describes Swedish educational policies and the challenges surrounding moving from policy to practice, and also uncovers themes regarding…

The purpose of this article is to report findings from an ethnographic study that focused on the co-development of science literacy and academic identity formulation within a third-grade classroom. Our theoretical framework draws from sociocultural theory and studies of scientific literacy. Through analysis of classroom discourse, we identified…

This project was initiated in order to evaluate two literacy and science integrated instruction units, "Shoreline Science" and "Terrarium Investigations," designed by the Lawrence Hall of Science "Seeds of Science/Roots of Reading" Project ("Seeds/Roots"). We examined how the integrated units affect student…

In this paper, the authors' investigated whether "Scott Foresman Science" program, a year-long curriculum intended for daily use that provides a sequence of structured and supportive inquiry activities and text materials to develop students' independent investigative skills, is more effective than current science programs in five diverse…
