Purpose: Using data from 1,868 children from the US, Australia, and Sweden who took a 10-word spelling test in kindergarten and a standardized spelling test in Grades 1, 2, and (except for the Australian children) Grade 4, we examined two questions. First, does the quality of a child's errors on the kindergarten test help predict later spelling…

Whole number computations are a critical skill that serves as a foundation upon which higher-order concepts in mathematics are taught to children. To facilitate their instruction, educators often use multiple representations to support a child's cognition. Representations with physical manipulatives are widely studied through a graduated…

Many students learn Turkish as a second language in Turkey. These students, whose first language is Kurdish, learn Turkish at a certain level before starting school. As a result, these students become emergent bilinguals along with school life. On the other hand, some of these students almost do not use Kurdish in their lives and wholly turn to…

The three purposes of this study were to (a) describe fraction ordering errors among at-risk fourth grade students, (b) assess the effect of part-whole understanding and accuracy of fraction magnitude estimation on the probability of committing errors, and (c) examine the effect of students' ability to explain comparing problems on the probability…

The present study aimed to examine the relationship between letter processing and word processing skills in deaf and hearing readers. The participants were 105 students (51 of them hearing, 54 of them deaf) who were evenly and randomly recruited from two levels of education (primary = 3rd-4th graders; middle = 6th-7th graders). The students were…

The purpose of this study was to investigate the use of linguistic knowledge in spelling by analyzing spelling errors made by 220 students in the fourth, fifth, and seventh grades. A 25-word researcher-designed spelling test with considerations of word frequency, word familiarity, and word type (based on morphological complexity) was administered.…

Rural students are at risk for vocabulary underdevelopment and often have less access to educational resources. The purpose of this investigation was to examine the effectiveness of an Internet-based Speech/Language Pathologist (SLP)-teacher consultation to support rural teachers' vocabulary instruction to improve their students' lexical…

Reading is an active process where readers sometimes have difficulty understanding what they read. Ultimately, readers are required to combine the meaning of each sentence in a text in order to achieve text-level comprehension. Otherwise, the reader is going to have great difficulty with text-level comprehension. Factors such as sentence length…

Two Monte Carlo simulations were performed to compare methods for estimating and testing hypotheses of quadratic effects in latent variable regression models. The methods considered in the current study were (a) a 2-stage moderated regression approach using latent variable scores, (b) an unconstrained product indicator approach, (c) a latent…

Errors in written multi-digit computation were investigated in children with math difficulties. Third- and fourth-grade children (n = 291) with coexisting math and reading difficulties, math difficulties, reading difficulties, or no learning difficulties were compared. A second analysis compared those with severe math learning difficulties, low…

The purpose of this quantitative study was to examine the use of a method of distractor analysis for diagnosing item error response patterns and determine the effect of this intervention on student achievement levels on state administered spring mathematics assessments. Distractor Pattern Functioning was the treatment provided to teachers in this…

The treatment of errors in mathematics classrooms has gained attention in recent years, with many researchers suggesting that errors should be used as starting points for student inquiry into mathematics. In the study reported in this article, we examined how teachers used discourse around errors to generate inquiry by looking at the treatment of…

The main hypotheses addressed in the research were (1) whether imprecision in the phonological representations of lexical items underlies the impaired expressive naming abilities of disabled readers, and (2) whether weak verbal memory might mediate the relationship between naming and reading skills. From samples of 93 first graders and 67 fourth…
