Fraction arithmetic facility is fundamental to learning more advanced math topics. However, attaining the ability to add and subtract fractions is hard for many students. The present longitudinal study examined students' growth on simple addition and subtraction word problems between fourth and sixth grades (N = 536). Latent class growth analyses…

The ability to express oneself through written language is a critically important skill for long-term educational, emotional, and social success. However, despite the importance of writing, English Learner students continue to perform at or below basic levels which warrants additional efforts to identify specific areas of weakness that impact…

Background: Children's spellings are often scored as correct or incorrect, but other measures may be better predictors of later spelling performance. Method: We examined seven measures of spelling in Reception Year and Year 1 (5-6 years old) as predictors of performance on a standardised spelling test in Year 2 (age 7). Results: Correctness was…

Spelling errors are considered a paramount criterion in the evaluation of written texts. The present study aimed: (1) to describe the developmental path of spelling errors in expository texts written by Hebrew-speaking children from the second to fifth grades; and (2) to reveal the predictive power of cognitive, linguistic and reading variables on…

This study examined Spanish spelling errors among 166 native Spanish-speaking students from Kindergarten to Grade 3 based on a spelling-to-diction task. Fifteen types of spelling errors were analyzed in a latent class analysis. Results suggested three phases of spellers: Phase 1 students had a high chance of committing almost all types of errors.…

Although educators frequently use assessment to identify who needs supplemental instruction and if that instruction is working, there is a lack of research investigating assessment that informs what instruction students need. The purpose of the current study was to determine if a brief (approximately 20 min) task that reflects a common middle…

Reading fluency involves a complex interaction of different cognitive skills and abilities that develop with instruction and practice and relies on the automaticity of many distinct reading skills (e.g., pacing, word recognition, expression, phonological awareness). Fluent reading frees cognitive resources, such as working memory, for more…

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…

Although research on cognitive correlates of spelling has been conducted, these studies generally do not distinguish between different types of targets that need to be spelled. Arguably, the contributions of these skills differ for words opposed to pseudowords and for targets that can be spelled on the basis of phoneme-to-grapheme conversion…

Purpose: The purpose of this study was to examine (a) whether increased grammatical error rates during a standardized narrative task are a more clinically useful marker of central nervous system abnormality in Fetal Alcohol Spectrum Disorders (FASD) than common measures of productivity or grammatical complexity and (b) whether combining the rate…

In an intelligent tutoring system (ITS), it can be useful to know when a student has disengaged from a task and might benefit from a particular intervention. However, predicting disengagement on a trial-by-trial basis is a challenging problem, particularly in complex cognitive domains. In the present work, data-driven methods were used to address…

Purpose: The purpose of this descriptive study is to investigate why some elementary children have difficulties mastering addition and subtraction calculation tasks. Design/methodology/approach: The researchers have examined error types in addition and subtraction calculation made by 697 Portuguese students in elementary grades. Each student…

Children with specific language impairments (SLI) have difficulties in producing written text. It was hypothesised that the constraints on writing in children with SLI were similar to typically developing younger children with the same level of vocabulary knowledge. Twenty-three children with SLI (aged 10:5) were matched with 23 children for…

We examined the instability of reading errors, that is whether a child reads the same word sometimes correctly and sometimes incorrectly, as a function of the complexity of context-sensitive spelling rules (vowel degemination and consonant gemination). Dutch bisyllabic words were read twice by typical readers in Grades 2 and 3, and reading-level…

This paper investigates how individuals' performances of a cognitive task in a high-pressure competition are affected by their peers' performances. To do so, I use novel data from the National Spelling Bee, in which students attempt to spell words correctly in a tournament setting. Across OLS and instrumental variables approaches, I…
