In this secondary analysis study, the authors explored the relations between reading comprehension and oral reading performance in fourth-grade students, using a data set from the U.S. National Assessment of Educational Progress (NAEP) special study of oral reading. The data set consisted of 1,713 students randomly selected from the 140,000 fourth…

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…

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 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 purpose of this study was to illustrate a polytomous IRT-based linking procedure that adjusts for rater variations. Test scores from two administrations of a statewide reading assessment were used. An anchor set of Year 1 students' constructed responses were rescored by Year 2 raters. To adjust for year-to-year rater variation in IRT…
