Thirty-five gifted elementary children were tested with the Wechsler Intelligence Scale for Children III (WISC-III) and results were compared to a previous administration of the WISC (Revised). Scores were significantly higher on all three WISC-R global scales and most subtest scaled scores. Correlation coefficients between the tests were…

The Mantel-Haenszel (MH) procedure has become one of the most popular procedures for detecting differential item functioning (DIF). One of the most troublesome criticisms of this procedure is that while detection rates for uniform DIF are very good, the procedure is not sensitive to non-uniform DIF. In this study, examinee responses were generated…

The Kindergarten Extended Day (KED) Program provided supplementary instruction for kindergarten pupils tested with the Cooperative Preschool Inventory (CPI) and identified as having educational deficiencies. Pupils in the Elementary Secondary Education Act Title I program attended school for a full day. Academic achievement of pupils relative to…

Research relating to the factor structure of the Sixteen Personality Factor Questionnaire (16PF) and the Clinical Analysis Questionnaire is reviewed. Different opinions about the factors measured by the 16PF are discussed. Focusing on the second-order factor level could eliminate problems with the instruments' reliability. (SLD)

A method of automatically selecting items for inclusion in a test with constraints on item content and statistical properties was applied to real data. Tests constructed manually from the same data and constraints were compared to tests constructed automatically. Results show areas in which automated assembly can improve test construction. (SLD)

Report on the current trends and issues in American public education involving personal views of state-mandated testing, the 2000 NAEP reading and math assessments, President Bush's "No Child Left Behind" initiative, TIMSS-R Benchmarking Studies, education vouchers, charter schools, and education management organizations. (Contains 52…

To examine the external validity of DSM-IV childhood disintegrative disorder (CDD), 10 children (M = 8.2 yrs) with CDD and 152 gender- and age-matched children with autistic disorder (AD) were compared on 24 variables. The CDD children had a significantly higher rate of epilepsy, significantly less uneven intellectual functioning, and a tendency…

A group of non-native, early signing deaf children between the ages of 7 and 11 years were tested on a referential communication task. A group of hearing children matched for sex and mental and chronological age were also included in the study. The aim was to study the deaf children's ability to take another person's perspective in a task that…

This literature review summarizes what is currently known about the agreement among six measures of writing skills. Three of these methods involve the application of human judgment in scoring or rating a piece of writing: holistic, analytical, and primary trait scoring. Two methods involve anatomical or taxonomic analysis of a piece of writing:…

Addresses issues faced by institutions attempting to design school profiles to meet accountability standards. Reports of high-stakes test results can be skewed by choice of statistic type (percent of students passing versus mean scores), sample bias, geographical transients, and omission errors. Administrators must look beyond "common…

Charter schools--public schools that are exempt from many of the procedural regulations that apply to regular public schools--are a widespread but poorly-studied form of education reform. With nearly 2,700 charter schools now educating more than 684,000 children nationwide, policymakers and parents need to know how the education charter schools…

Problems of scale typically arise when comparing test score trends, gaps, and gap trends across different tests. To overcome some of these difficulties, we can express the difference between the observed test performance of two groups with graphs or statistics that are metric-free (i.e., invariant under positive monotonic transformations of the…

One hundred nine college students participated in an experiment that involved reading a passage and responding to a 20-item multiple choice test. The students were randomly assigned to one of four groups. The four conditions involved reading and copying, reading and highlighting, reading and taking notes, and reading and generating questions.…

In September 2005 the National Foundation for Educational Research (NFER) in association with the Department for Education and Skills (DfES), the Sutton Trust and the College Board, began a five-year research study to examine the validity of an aptitude test in higher education admissions. This report describes and explores the relationships…

The power of the procedure of W. Stout to detect deviations from essential unidimensionality in two-dimensional data was investigated for minor, moderate, and large deviations from unidimensionality using criteria for deviations from unidimensionality based on prior research. Test lengths of 20 and 40 items and sample sizes of 700 and 1,500 were…
