The Universal Design for Play (UDP) Tool is an instrument designed to evaluate the presence of universal design (UD) features in toys. This study evaluated its psychometric properties, including content validity, construct validity, and test-retest reliability. The UDP tool was designed to assist in selecting toys most appropriate for children…

Bernoulli's framework of expected utility serves as a model for various psychological processes, including motivation, moral sense, attitudes, and decision making. To account for evidence at variance with expected utility, the authors generalize the framework of fast and frugal heuristics from inferences to preferences. The priority heuristic…

Spearman's "Law of Diminishing Returns" states that the g saturation of a test is greater for individuals with lower, rather than higher, test scores, and that it decreases with age. A common methodological problem in testing Spearman's "Law of Diminishing Returns" with respect to ability differentiation is how to create the…

We aimed to design alternative estimates of pre-morbid/prior intelligence to the National Adult Reading Test (NART) and the Spot-the-Word (STW) in order to tap non-vocabulary based knowledge stores. The rationale for the development of the new tests was that more cognitively able individuals acquire and retain more "singular facts" from their…

This paper presents a hierarchical Bayes circumplex model for ordinal ratings data. The circumplex model was proposed to represent the circular ordering of items in psychological testing by imposing inequalities on the correlations of the items. We provide a specification of the circumplex, propose identifying constraints and conjugate priors for…

Can an explanation of the origins of social disparities in educational achievement be assisted by a critical examination of Bernstein's sociology? This central question is approached by a consideration of the status of Bernstein's socio-linguistic thesis. The focus is on the nature of the explanations provided. The paper asks: What is the…

This article describes research instruments that facilitate the description of teachers' beliefs and practices and their use with further education (FE) mathematics teachers. They consist of linked questionnaires aimed at both teachers and students, validated by cross-referencing with more open questionnaires and with classroom observation. They…

The objective of this study was to refine the Children's Social Behavior Questionnaire (CSBQ), to reduce its length, and to verify its psychometric properties. The CSBQ is a questionnaire for parents or caregivers of children with PDD. The items describe a broad range of features that are typical of PDD, particularly in its milder forms. Based on…

The purpose of this mixed-methods study was to document the prevalence of sampling designs utilised in mixed-methods research and to examine the interpretive consistency between interpretations made in mixed-methods studies and the sampling design used. Classification of studies was based on a two-dimensional mixed-methods sampling model. This…

This study provides a framework for the evaluation of assessments that may be used in adult continuing education. It provides an example of the analysis of an examination for 33 solicitors seeking specialist accreditation. Resampling was used to generate a group of 1000 results, and responses were analysed using a Rasch model. Results indicated a…

In 2003, a trial National Assessment of Educational Progress (NAEP) mathematics assessment was administered in Spanish to public school students at grades 4 and 8 in Puerto Rico. Based on preliminary analyses of the 2003 data, changes were made in administration and translation procedures for the 2005 NAEP administration in Puerto Rico. This…

This study examined a model of assessment that could be applied nationally for Year Twelve Vocational Education and Training (VET) subjects and which could yield both a differentiating score and recognition of competence. More than fifty colleges across all states and territories of Australia field-tested the approach over one school year. Results…

A study demonstrated the utility of item analyses to investigate which items function well or poorly in a second language reading recall protocol instrument. Data were drawn from a larger study of 56 learners of German as a second language at various proficiency levels. Pausal units of scored recall protocols were analyzed using both classical…

Basic precepts for test development are described and explained as they are presented in measurement textbooks commonly used in the fields of education and psychology. The five building blocks discussed as the foundation of well-constructed tests are: (1) specification of purpose; (2) standard conditions; (3) consistency; (4) validity; and (5)…

Classroom teachers use intuitions, experiences, syllabi, and course guides to help implement a curriculum. Psychometric techniques can also help guide and shape curricula. Some psychometric techniques allow tests to reveal the actual curriculum mastered by students in an objective and sample-free manner and to indicate a probable learning sequence…
