Recent research suggests using multiple screening measures to identify students at risk for academic difficulties may decrease the number of students incorrectly identified as such. Gated frameworks in which students that score below a cut-score on an initial measure are assessed with a follow-up measure have been recommended. Researchers have…

This inquiry is focused on three indicators of the precision of measurement--conditional on fixed values of ?, the latent variable of item response theory (IRT). The indicators that are compared are (1) The traditional, conditional standard errors, s(eX|?) = CSEM; (2) the IRT-based conditional standard errors, s[subscript irt](eX|?)=C[subscript…

Previous research in child language shows that many aspects of language acquisition are frequency-linked. This study tests whether input or usage frequency predicts the order of acquisition and accuracy of a bilingual Greek-English child's English possessives. The child was followed longitudinally from age 2;6 to 3;11. Order of acquisition was…

We investigated how and when French children in Grades 1-5 acquire orthographic representations for silent letters and double consonants. Linear mixed-effects modeling analyses on the spelling accuracy scores obtained for 2,519 French words were used to test our predictions. As predicted, the presence of a silent letter or double consonant had a…

Variations in the accuracy and stability of a word's spelling can be used to gauge the quality of its underlying orthographic representation. The Lexical Quality Hypothesis (LQH) contends that words with higher quality cognitive representations should be accessed more efficiently than those with lower quality representations. If this is the case,…

Memory for numbers improves with age. One source of this improvement may be learning linear spatial-numeric associations, but previous evidence for this hypothesis likely confounded memory span with quality of numerical magnitude representations and failed to distinguish spatial-numeric mappings from other numeric abilities, such as counting or…

As the Government Accountability Office (GAO) reported in February 2019, the Department of Education's (Education) data suggest that the restraint and seclusion of K-12 public school students is rare nationwide, though it disproportionately affects students with disabilities and boys in general. In broad terms, Education defines restraint as…

A set of four experiments assessed the effects of establishing a comprehension-test expectancy (in contrast to a memory-test expectancy) on relative metacomprehension accuracy. Typically readers show poor relative metacomprehension accuracy while learning from text (i.e., they are unable to discriminate topics they have understood well from topics…

Computational models of learning can be powerful tools to test educational technologies, automate the authoring of instructional software, and advance theories of learning. These mechanistic models of learning, which instantiate computational theories of the learning process, are capable of making predictions about learners' performance in…

Massive Open Online Courses (MOOCs) have become more and more popular recently. These courses have attracted a large number of students world-wide. In a popular course, there may be thousands of students. Such a large number of students in one course makes it infeasible for the instructors to grade all the submissions. Peer assessment is thus an…

Since 2010, the Community Eligibility Provision (CEP) has expanded access to free school meals while jeopardizing a key measure of student poverty used across the field of education: free and reduced-price lunch (FRPL) status. States and school districts are pioneering alternative measures of student poverty, which vary in their composition and…

As spatial languages, sign languages rely on spatial cognitive processes that are not involved for spoken languages. Interlocutors have different visual perspectives of the signer's hands requiring a mental transformation for successful communication about spatial scenes. It is unknown whether visual-spatial perspective-taking (VSPT) or mental…

Student growth percentiles (SGPs) are currently used by several states and school districts to provide information about individual students as well as to evaluate teachers, schools, and school districts. For SGPs to be defensible for these purposes, they should be reliable. In this study, we examine the amount of systematic and random error in…

The skill of spatial learning and orientation is fundamental in humans and differs widely among individuals. Despite its importance, however, the malleability of this skill through practice has scarcely been studied empirically, in contrast to psychometric spatial ability. Thus, this article examines the possibility of improving the accuracy of…

Current composition practice relies on a decades-old summary of research concluding that a focus on grammar in students' writing is useless, or even harmful. Conversely, hundreds of recent studies from the fields of second-language writing and applied linguistics claim to provide evidence of the benefits to providing feedback on grammar in…
