Educationally-oriented measures of handwriting fluency--tasks such as written alphabet recall and sentence copying--conflate graphomotor skill and various higher-level abilities. Direct measurement of pen control when forming letters requires analysis of pen-tip velocity associated with the production of sub-letter features that, in a skilled…

This study investigated the relationships between metalinguistic skills, including phonological, orthographic, and morphological awareness, and Hangul-word spelling in Korean first through third graders, encompassing both deaf and hard of hearing (DHH) children and children with typical hearing (TH). The participants comprised 24 children with…

Children's early accuracy on place value (PV) tasks longitudinally predicts their later multidigit calculation skills. However, another window into children's emerging base-ten concepts is the pattern of errors -- "smart errors" -- they exhibit on these measures. Past research has speculated that these smart errors -- similar to invented…

Arabic is a diglossic language, where two language varieties are used: spoken Arabic (SpA) and standard Arabic (StA). The words may be "identical" (maintaining the same phonological expression in the SpA and StA) or "unique" to StA). This study examined the effect of diglossia on reading according to the lexical distance…

It is widely recognized that individuals with dyslexia have difficulties with word reading "and" spelling, and individuals with reading comprehension difficulties have low vocabulary knowledge. However, little is known about the extent to which spelling and vocabulary are informative of reading difficulties. In the present study, we…

Children's word problem competence is a major determinant of their career prospects. Abstract word (AW) comprehension and equal sign knowledge (ESK) are considered the foundation of discourse comprehension and pre-algebra skills, respectively. However, the link between AW and ESK in relation to the meaningful agent representative information…

Extensive research has demonstrated the importance of struggling reader identification in monolingual children Compton et al. ("Journal of Educational Psychology," 102, 327-340, 2010). However, very few studies have explored identification of struggling readers in bilinguals. The aim of this study was to investigate (1) the overlap of…

It is widely recognized that individuals with dyslexia have difficulties with word reading and spelling, and individuals with reading comprehension difficulties have low vocabulary knowledge. However, little is known about the extent to which spelling and vocabulary are informative of reading difficulties. In the present study, we investigated…

The transition from informal to formal mathematics is an important episode in children's mathematical development. The current study investigated how young children's computational estimation performance and strategy use develops in this transitional period. The computational estimation performance of 350 children was assessed before the start of…

For the proper development of writing, teachers must choose the best line for their students. To this day, it is still not very clear which is the correct or the most suitable letter for the beginning of this learning process. However, there are certain parameters that allow us to observe the "pros" and "cons" that have been…

Elementary social studies resources have faced criticism for well over 30 years. Text that is too complex (Beck et al., 1989; Beck & McKeown, 1991), contains questionable content (Chu, 2017; Wade, 2012), and is boring to students (Kelley, 2021; Schug, 1982) and teachers (Zhao & Hoge, 2010). More recent studies have found that teachers are…

Little is known about what contributes to individual differences in reading fluency after accounting for accuracy. Previous research has shown individual differences in the relative growth in word and nonword reading, specifically a pattern in which students who start lower on reading grow more in word than nonword reading ability. The purpose of…

Children's ability to discriminate nonsymbolic number (e.g., the number of items in a set) is a commonly studied predictor of later math skills. Number discrimination improves throughout development, but what drives this improvement is unclear. Competing theories suggest that it may be due to a sharpening numerical representation or an improved…

This study aimed to address the need for a comprehensive assessment tool to evaluate the mathematical abilities of first-grade students through cognitive diagnostic assessment (CDA). The primary challenge involved in this endeavor was to delineate the specific cognitive skills and sub-skills pertinent to first-grade mathematics (FG-M) and to…

We explored reading comprehension development in children on the spectrum from pre-school to the first (YOS1) and third year of schooling (YOS3). Children were first assessed on meaning-related skills in pre-school. Forty-one children completed follow-up assessments of reading comprehension, reading accuracy, and listening comprehension in YOS1.…
