The purpose of the current study is to describe the development and validation of a new measure of temperament, the Preschool Temperament Classification System (PTCS). The PTCS was developed as a typological measure that identifies children's temperament styles as undercontrolled, resilient, or overcontrolled. The PTCS is a time efficient…

Much previous research into the effectiveness of CMC has suffered from a lack of clarity or of consistency in the adoption and explication of coding typologies or taxonomies. This has reduced the opportunities for comparison between studies and for the accumulation of evidences to guide pedagogy. In addition, most studies of CMC have used…

In 3 experiments, 9-month-old infants' expectations for what distinct count noun labels refer to were investigated. In Experiment 1, a box was opened to reveal 2 objects inside during familiarization: either 2 identical objects or 2 different objects. Test trials followed the same procedure, except before the box was opened, the contents were…

Taxometric procedures provide an empirical means of determining which psychiatric disorders are typologically distinct from normal behavioral functioning. Although most disorders reflect extremes along continuously distributed behavioral traits, identifying those that are discrete has important implications for accurate diagnosis, effective…

This paper reports on an ESRC-funded project that investigated the use of corpus-based activities in a primary-school context, with children aged 8-10 years. The study explored the contributions that could be made by a corpus--comprising language written for a child audience--and a modified version of the associated software, in helping these…

In this article, the authors examine the components of leadership for learning employing research on highly productive schools and school districts and high-performing principals and superintendents, using a three-dimensional model of productivity. The knowledge base of leadership for learning is captured under eight major dimensions: vision for…

This is the 32nd Annual Report to Congress on the Implementation of the Individuals with Disabilities Education Act, 2010. Section 664(d) of the Individuals with Disabilities Education Act (IDEA) (P.L. 108-446), as reauthorized in 2004, requires that the Department of Education report annually on the progress made toward the provision of a free…

In this research project, subject terms from the Dewey Decimal Classification (DDC) Schedules and Relative Index were incorporated into an online catalog as searcher's tools for subject access, browsing, and display. Four features of the DDC were employed to help searchers browse for and match their own subject terms with the online catalog's…

To examine the link between analytic and holistic modes of processing and the amount of domain knowledge, 2 category-learning studies were conducted with 5-year-old children. In the first study, 26 kindergarten children were classified according to their verbal knowledge about plants and their familiarity with flowers. They then performed a…

Cut scores, quartile ranking, sample size, and overall classification scheme were studied as personnel selection procedures in two samples. The first was 120 simulated observations of employee scores based on actual selection procedures for applicants for administrative assistant positions. The other sample was composed of test results for 73…

Professionals responsible for educational research, evaluation, and statistics have sought to provide timely and useful information to decision makers. Regardless of the evaluation model, research design, or statistical methodology employed, informing the decision making process with quality, reliable data is a basic goal. The definition of…

In 1992, RAND received a grant from the National Science Foundation to study the technical quality of performance assessments in science and to evaluate their feasibility for use in large-scale testing programs. The specific goals of the project were to assess the reliability and validity of hands-on science testing and to investigate the cost and…

A new approach to the study of text building behavior is possible through the application of Scanator. This paper consists of a demonstration of some of its fundamental functions. These are suitable in a study of text building. The basic concepts, expressed through an analysis of a small part of an interview text, derive from a thermodynamic…

This study examined whether children (ages 6-16) diagnosed as having attention deficit disorder with hyperactivity (ADD/H) could be differentiated from those diagnosed as having attention deficit disorder without hyperactivity (ADD/WO), on an anterior-posterior gradient paradigm. It was predicted that ADD/H children (N=23) would have more deficits…

The implications of the 1994 Seels and Richey domain structure for instructional technology (IT) conceptual theory and classification systems, in general, for theory construction are explored. The historical evolution of domains in definitions of the field, the formulation of theory, the nature of taxonomies, the role of conceptual frameworks and…
