Statistical analysis of categorical data often relies on multiway contingency tables; yet, as the number of categories and/or variables increases, the number of table cells with few (or zero) observations also increases. Unfortunately, sparse contingency tables invalidate the use of standard goodness-of-fit statistics. Limited-information fit…

Diagnostic tools can help schools more consistently and fairly match instructional resources to the needs of their students. To ensure the best educational outcome for each child, diagnostic decision-making systems seek to balance time, clarity, and accuracy. However, recent research notes that many educational decisions tend to be made using…

Self-report surveys are widely used to measure adolescent risk behavior and academic adjustment, with results having an impact on national policy, assessment of school quality, and evaluation of school interventions. However, data obtained from self-reports can be distorted when adolescents intentionally provide inaccurate or careless responses.…

This study investigates the use of the Spanish subjunctive in bilingual children with and without specific language impairments (SLI). Using an elicitation task, we examine: (i) the potential of the subjunctive as a grammatical marker of SLI in Spanish-English bilingual children, (ii) the extent to which degree of bilingualism affects performance,…

This study presents construct validity for a novel automated morphometric and kinematic handwriting assessment, including (1) convergent validity, establishing reliability of automated measures with traditional manual-derived Minnesota Handwriting Assessment (MHA), and (2) discriminant validity, establishing that the automated methods distinguish…

Children who are Spanish-speaking English-language learners (ELLs) comprise a rapidly growing percentage of the population in U.S. schools. To determine which of these children have weaker emergent literacy skills and are in need of intervention, it is necessary to assess emergent literacy skills accurately and reliably. In this study, 1,318…

Research Findings: The purpose of this study was to describe differences in the narratives produced by 3-, 4-, and 5- year old Spanish-speaking (SS) children. Narrative productions of 104 typically developing children were collected using a story-retelling task and coded using the Index of Narrative Complexity. The results of this study indicate…

A new method for a quantitative and objective description of drawing and for the quantification of drawing ability in children with learning disabilities (LD) is hereby presented. Twenty-four normally developing children (N) (age 10.6 [plus or minus] 0.5) and 18 children with learning disabilities (LD) (age 10.3 [plus or minus] 2.4) took part to…

Background: All types of librarians are expected to possess information and computer skills to actively assist patrons in accessing information and in recognizing reputable sources. Mastery of information and computer skills is a high priority for library and information science programs since graduate students have varied multidisciplinary…

A significant body of research exists on the development of early literacy skills and their relationship to the development of literacy as a whole. Phonological awareness, orthographic processing, rapid automatized naming, phonological memory, and receptive vocabulary have all been shown to be predictive of early reading outcome measures. What is…

The purpose of this study was to compare the effectiveness of the Raven's Standard Progressive Matrices, the Naglieri Nonverbal Abilities Test (NNAT), and the Iowa Test of Basic Skills (ITBS) in selecting for ethnically diverse students who may be gifted. The participants of the study were 175 students enrolled in Grades 3-5 and Grade 8 in a…
