Teachers' ability to accurately judge difficulties of mathematical tasks is an essential aspect of their diagnostic competencies. Although research has suggested that pedagogical content knowledge (PCK) is positively correlated with the accuracy of diagnostic judgments, experimental studies have not been conducted to investigate how PCK affects…

Facilitated identification of predictable words during online reading has been attributed to the generation of predictions about upcoming words. But highly predictable words are relatively infrequent in natural texts, raising questions about the utility and ubiquity of anticipatory prediction strategies. This study investigated the contribution of…

This investigation identified dimensions of narrative, persuasive, and expository writing in Grades 1 to 12 and assessed the contribution of speech-language pathologists' (SLPs) indices to scores on teachers' 6 traits rubric. Findings could facilitate development of effective intervention programs for writing. A corpus of narrative, expository,…

Purpose: Children with developmental language disorder (DLD) demonstrate general spelling difficulties. This study investigated accuracy on and sensitivity to silent letters in spelling in children with and without DLD. Investigating silent-letter production provides a window into orthographic and morphological knowledge and enhances understanding…

Analyzing the writing skill of English language learners emerges from understanding the accuracy, fluency, and complexity of texts and classifying written errors according to syntax, morphology, and lexicon. In this quantitative descriptive-analysis study, the participants included thirty one Spanish-speaking, Mexican English language learners who…

We conducted a skills analysis on written expression curriculum-based measurement (WE-CBM) tasks completed by 117 second-grade students. As part of the skills analysis, we scored two WE-CBM tasks (i.e., narrative and expository) for correct and incorrect writing sequences, common writing errors, and sentence structures. Although a majority of…

The objective of the present study is to examine the error patterns for Persian reading and spelling when controlling for the complexity level of words. A sample of 140 children attending Grades 1-4 in Iran read and spelled the same words that differed in reading transparency (transparent vs. opaque) and spelling consistency (monographic vs.…

Background: Of the myriad of reading comprehension (RC) assessments used in schools, multiple-choice (MC) questions continue to be one of the most prevalent formats used by educators and researchers. Outcomes from RC assessments dictate many critical factors encountered during a student's academic career, and it is crucial that we gain a deeper…

Purpose: This study examines the response patterns of 278 Spanish-English dual language learners (DLLs) on a standardized test of receptive English vocabulary. Method: Investigators analyzed responses to 131 items on the Peabody Picture Vocabulary Test--Fourth Edition (Dunn & Dunn, 2007) focusing on differential accuracy on items influenced by…

Purpose: Using a blocked cyclic picture-naming task, we compared accuracy and error patterns across languages for Spanish-English bilingual children with and without developmental language disorder (DLD). Method: Pictured stimuli were manipulated for semantic similarity across two (Same and Mixed) category contexts. Children's productions were…

This retrospective, exploratory investigation examined the types of target words that 66 children with/without word-finding difficulties (WFD) had difficulty naming, and the types of errors they made. Words were studied with reference to lexical factors (LFs) that might influence naming performance: word frequency, familiarity, length, phonotactic…

Though proficiency with computation is highly emphasized in national mathematics standards, students with mathematics difficulty (MD) continue to struggle with computation. To learn more about the differences in computation error patterns between typically achieving students and students with MD, we assessed 478 third-grade students on a measure…

This paper attempts to quantify the accuracy limit of "nextitem-correct" prediction by using numerical optimization to estimate the student's probability of getting each question correct given a complete sequence of item responses. This optimization is performed without an explicit parameterized model of student behavior, but with the…

Spelling is a language problem-space, not only a school subject. Successful spelling demands going beyond letter to sound mapping and gaining access to a full representation of the orthographic structure of words. We traced bilingual Catalan/Spanish speakers' spelling performance in Catalan across elementary school in two tasks: isolated words to…

Background: Of the myriad of reading comprehension (RC) assessments used in schools, multiple-choice (MC) questions continue to be one of the most prevalent formats used by educators and researchers. Outcomes from RC assessments dictate many critical factors encountered during a student's academic career, and it is crucial that we gain a deeper…
