Dyslexia is a specific learning disability in reading and writing, which requires adequate early intervention to prevent future school failure. We describe the diagnostic assessment of a 7-year-old boy labelled "dyslexic", the evaluation of his family, social, medical, developmental, and academic status as a preliminary for the design…

This study investigated the role of generative strategies and working memory capacity on word problem solving accuracy in children with math difficulties (MD). Within classrooms, children in Grade 3 with MD ("n" = 69) were randomly assigned to one of three treatment conditions: paraphrase question propositions (Restate), paraphrase…

The effects of aging and IQ on performance were examined in 4 memory tasks: item recognition, associative recognition, cued recall, and free recall. For item and associative recognition, accuracy and the response time (RT) distributions for correct and error responses were explained by Ratcliff's (1978) diffusion model at the level of individual…

Audience response systems (ARS) are gaining popularity in multiple areas of education. Although its usefulness has been well reported, no study has investigated the accuracy of the technology. The purpose of this study was to validate ARS by assessing three key aspects: signal transmission from the keypad to the receiver, capture of a proper…

The motivational pattern of adolescents with biased and accurate self-efficacy beliefs in language and/or in math was examined in the current study. A sample of 6119 adolescents completed self-report questionnaires measuring self-efficacy beliefs for language and math, their interest in each subject, persistence, achievement goal orientations, and…

This study examines the predictive validity of literacy measures from the Dynamic Indicators of Basic Early Literacy Skills (DIBELS) for Spanish-speaking English language learners (ELs). Third grade EL students were screened three times during the year with DIBELS Oral Reading Fluency (DORF) and Daze. Predictive validity of the scores was examined…

Content balancing is one of the most important components in the computerized adaptive testing (CAT) especially in the K to 12 large scale tests that complex constraint structure is required to cover a broad spectrum of content. The purpose of this study is to compare the weighted penalty model (WPM) and the weighted deviation method (WDM) under…

Individuals with an autism spectrum disorder (ASD) often present with co-occurring emotional and behavioral disorders (EBD). The Child Behavior Checklist 6-18 (CBCL; Achenbach & Rescorla, 2001) is an EBD measure that contains several norm-referenced scales derived through factor analysis of data from the general pediatric population. The…

We investigated the effects of morphological awareness on five measures of reading in 103 children from Grades 1 to 3. Morphological awareness was assessed with a word analogy task that included a wide range of morphological transformations. Results indicated that the new measure had satisfactory reliability, and that morphological awareness was a…

Background: Children with specific language impairments (SLI) repeat nonwords less accurately than typically developing children, suggesting a phonological deficit. Much work has attempted to explain these results in terms of a phonological memory deficit. However, subsequent work revealed that these results might be explained better as a deficit…

The purpose was to evaluate the lexicality of treated stimuli relative to phonological learning by preschool children with functional phonological disorders. Four children were paired in a single-subject alternating treatments design that was overlaid on a multiple baseline across subjects design. Within each pair, one child was taught one sound…

Our aim was to deepen understanding of public examinations, exploring how marking task demands influence examiners' cognition and ultimately their marking accuracy. To do this, we identified features of examinations that trigger or demand the use of cognitive marking strategies entailing "reflective" judgements. Kelly's Repertory Grid…

In this longitudinal study, we investigated the role of word reading and mathematical difficulties measured in 9th grade as factors for receiving educational support for learning in upper secondary education in Grades 10 to 12 (from ages 16 to 19) and furthermore as predictors of dropout from upper secondary education within 5 years after…

This study investigated the role of strategy instruction and working memory capacity (WMC) on word problem solving accuracy in children with (n = 100) and without (n = 92) math difficulties (MD). Within classrooms, children in Grades 2 and 3 were randomly assigned to one of four treatment conditions: verbal-only strategies (e.g., underlining…

This study investigates the structure and cross-cultural (in)variance of mathematical self-beliefs in relation to mathematics achievement in two world regions: Confucian Asia (Singapore, South Korea, Hong Kong and Taiwan) and Europe (Denmark, The Netherlands, Finland, Serbia and Latvia). This is done both pan-culturally and at a multigroup-level,…
