Purpose: Children make spelling errors despite classroom instruction on phoneme-grapheme connections and spelling rules. We examined whether additional practice helps to decrease the number of spelling errors for a morphological spelling rule. We distinguished explicit practice in applying a spelling rule from implicit exposure to correct word…

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…

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…

The morphological structure of the word has a central function in the organization of the mental lexicon and word recognition. Polymorphemic words in Arabic are composed of two non-concatenated morphemes: root and word-pattern. This study is the first to address the issue of nominal-pattern priming among young developing Arabic speakers. I…

The current study examined the development of two effects that have been found in single-digit multiplication errors: relatedness and distance. Typically achieving (TA) second, fourth, and sixth graders and adults, and sixth and eighth graders with a mathematics learning disability (MLD) performed a verification task. Relatedness was defined by a…

The current experiments examined the role of scale factor in children's proportional reasoning. Experiment 1 used a choice task and Experiment 2 used a production task to examine the abilities of kindergartners through fourth-graders to match equivalent, visually depicted proportional relations. The findings of both experiments show that accuracy…
