The language that students use with whole numbers can be insufficient when learning integers. This is often the case when children interpret addition as "getting more" or "going higher." In this study, we explore whether instruction on mapping directed magnitudes to operations helps 88 second graders and 70 fourth graders solve…

The contributions of domain-general abilities and domain-specific knowledge to subsequent mathematics achievement were longitudinally assessed (n = 167) through 8th grade. First grade intelligence and working memory and prior grade reading achievement indexed domain-general effects, and domain-specific effects were indexed by prior grade…

Purpose: This study investigated cumulative effects of language learning, specifically whether prior vocabulary knowledge or special education status moderated the effects of academic vocabulary instruction in high-poverty schools. Method: Effects of a supplemental intervention targeting academic vocabulary in first through third grades were…

Although many studies have focused on the importance of school composition for student achievement, there is still no consensus on "whether" school composition matters to student achievement, and, if so, "why". Therefore, the present study investigates the association between school composition and mathematics achievement at…

Spatial discontinuity between causes and effects is a feature of many scientific concepts, particularly those in the environmental and ecological sciences. Causes can be spatially separated from their effects by great distances. Action at a distance, the idea that causes and effects can be separated in physical space, is a well-studied concept in…

Recent psychological studies as well as research findings in mathematics education highlight the significance of early number skills for the child's achievement in mathematics at the end of primary school. In this context, first results from an ongoing four-year longitudinal study are reported. The study investigates the development of early…

The purpose of this study was to examine how readers build orthographic knowledge for irregular words, defined as words that do not conform to conventional phonics rules and patterns. This study tests my theory that readers use phonological decoding, crosschecking and mental markings to read and spell unfamiliar irregular words. Forty-three…

Documenting how students with learning disabilities (LD) initially conceive of fractional quantities, and how their understandings may align with or differ from students with mathematics difficulties, is necessary to guide development of assessments and interventions that attach to unique ways of thinking or inherent difficulties these students…

Traditional measures of reading ability designed for younger students typically focus on componential skills (e.g., decoding, vocabulary), and the items are often presented in a discrete and decontextualized format. The current study was designed to explore whether it was feasible to develop a more integrated, scenario-based assessment of…

As teachers and leaders move forward in implementing the Common Core State Standards within classrooms across 46 states, it is essential to consider the question of what knowledge is included in the English Language Arts Standards, and what knowledge is not present. The authors of the Common Core delineate an increasingly complex body of knowledge…

Students can learn subjects more meaningfully through integrated education, as it helps them to link school education with their real lives. There is a strong need to develop an alternative integration method to promote effective implementation of integrated education at a classroom level. The purpose of this study was to develop a model for…

The use of teaching practices that involve intertextual relationship discovery in today's elementary classrooms is increasingly essential to the success of young learners of reading. Teachers must constantly strive to expand their perspective of how to incorporate the dialogue included in prior knowledge assessment. Teachers must also consider how…

This article examined the ability of young children to adapt their trust in testimony in relation to the strength of their prior knowledge across 2 cultures and 2 age groups. Kindergartners and second graders in the United States and Hong Kong (N = 128) viewed pictures of objects and made category judgments about each object: first, in the…

The purpose of this study was to describe how an accomplished teacher taught second-grade students to design games that integrated movement and mathematics content. The participants were one physical education teacher, a classroom teacher, and an intact class of 20 second-grade students. Qualitative data were gathered through videotaping of all…
