Many states now mandate early screening for dyslexia, but vary in how they address these mandates. There is confusion about the nature of screening versus diagnostic assessments, risk versus diagnosis, concurrent versus predictive validity, and inattention to indices of classification accuracy as the basis for determining risk. To help define what…

There is some evidence that reading and spelling are complementary processes. The purpose of this study was to investigate the extent to which contextualized spelling (i.e., spelling activities within the context of reading instruction) is used to support reading in first-grade core reading programs. Analysis of 75 lessons across five programs…

Early literacy and reading skills are both important predictors of an individual's future success in school and employment settings (Moats, 1999). Moreover, poor reading performance in elementary school has been associated with future conduct problems and juvenile delinquency by age fifteen (Williams, 1994). Research supports the notion that…

The developmental sequence of the types of orthographic knowledge that children acquire early in reading development is unclear. Following findings of skilled reading, the orthographic constraints of positional frequency and feedback consistency were explored with a wordlikeness judgement task for grades 1-3 English-speaking children. The data…

This study examined the psychometric proprieties of the Arabic version of the Curriculum-Based Measurement Oral Reading Fluency (CBM ORF) for Jordanian students. A sample of 200 students (six to eight years old) was recruited from four public primary schools in Jordan. Results indicated that the CBM ORF had adequate reliability and validity…

The purpose of this study was to examine the impact of probe variability on the ability to replicate results in brief experimental analysis (BEA) of reading. In the first phase of the study, 41 first- and second- grade students completed 16 oral reading fluency probes. Calculations of probe difficulty were used to identify Low and High Variability…

Research was conducted to evaluate how well the "Indiana Reading Assessment--Grade 1" evaluates various reading skills of grade one students. Multiple analyses were conducted; while the results of all the analyses were encouraging, the results derived from the concurrent validity study were most significant. All the correlations were…

Purpose: To scale language milestones in a group of 527 children to provide an instrument for screening language development. Procedure: The questionnaire regarding these milestones was completed by parental report. It was evaluated whether the scaled milestones satisfied the assumptions of the Mokken item response model. Results: The scalability…

Considerable evidence suggests that phonemic awareness is associated with the development of skilled reading. Consequently, it is recommended that beginning readers be assessed to ensure adequate development of phonemic awareness skills. When choosing an assessment method, reliability and validity, ease of administration and scoring, and…
