Reliability is a problem inherent in all educational assessments, but the amount of attention this particular problem should be given is related to the function and use of the assessment. In this article, classification accuracy is put forward as a conceptualization of reliability that is meaningful for a large number of educational assessments.…

Attachment Q-Sort (AQS) is a tool for quantifying observations about toddler/caregiver relationships. Previous studies have applied factor analysis to the full 90 AQS item set to explore the structure underlying them. Here we explore that structure by applying multidimensional scaling (MDS) to judgements of inter-item similarity. AQS items are…

This article proposes a taxonomy of strategies for single-digit multiplication, then uses it to elucidate the nature of the learning tasks involved in multiplication. In preceding work, it has generally been assumed that much of children's strategy development is driven by changes in their general conceptual capabilities relating to number. In…

An operational definition for "rural area" is pivotal if proposals, policies and decisions aimed at optimising the distribution of resources, closing the gap on inequity between areas and raising standards of living for the least advantaged populations are to be put in place. The concept of rurality, however, is often based on…

Category knowledge allows for both the determination of category membership and an understanding of what the members of a category are like. Diagnostic information is used to determine category membership; prototypical information reflects the most likely features given category membership. Two experiments examined 2 means of category learning,…

The study examined children's understanding of scientific inquiry, through the lens of their conceptualization of uncertainty in investigations they had designed and implemented with a partner. These largely student-regulated investigations followed a unit about animal behavior that emphasized the scaffolding of independent inquiry. Participants…

The aims of the present review are to apply a recent risk factor approach (H. C. Kraemer et al., 1997) to putative risk factors for eating disorders, to order these along a timeline, and to deduce general taxonomic questions. Putative risk factors were classified according to risk factor type, outcome (anorexia nervosa, bulimia nervosa,…

An important, sometimes controversial feature of all psychological phenomena is whether they are categorical or dimensional. A conceptual and psychometric framework is described for distinguishing whether the latent structure behind manifest categories (e.g., psychiatric diagnoses, attitude groups, or stages of development) is category-like or…

The typology studies reviewed in the Holtzworth-Munroe and Meehan article make considerable methodological and substantive contributions to the field. There are several definitional, conceptual, and methodological advances that can be explored in this work. Macroframeworks such as the nested ecological model and the theory of triadic influence…

This article takes as its starting point discussions on the nature of critical educational research. It seeks to highlight some potential pitfalls for the less experienced researcher entering the field for the first time. It also highlights the tension between the more mechanistic approaches involving categorisation and tendencies that are evident…

This paper describes an exercise in determining the cognitive difficulty of the assessment tasks in six computing courses within an Information Technology (IT) degree, importing Bloom's taxonomy from the field of educational psychology as an analytical framework. Three of the six courses comprise a Programming stream and three a Data…

This study investigated the ability to describe and categorize common objects following brain injury. Thirteen subjects with moderate to severe traumatic brain injury (TBI) and 13 noninjured controls participated in this project. The project consisted of 3 parts: 1. A spontaneous condition, 2. A training session, and 3. An application condition.…

A well-known asymmetry exists in the bilingual masked priming literature in which lexical decision is used: namely, masked primes in the dominant language (L1) facilitate decision times on targets in the less dominant language (L2), but not vice versa. In semantic categorization, on the other hand, priming is symmetrical. In Experiments 1-3 we…

This study provides a profile of the actions taken by Australian universities to diversify their revenue streams in order to generate more independent non-government) income. Marginson's taxonomy of Australian universities is used to catergorise universities and contrast levels of independent income (Marginson and Considine 2000). This study finds…

The Carnegie Commission on Higher Education was established by The Carnegie Foundation for the Advancement of Teaching in 1967 to study and make recommendations regarding the major issues facing U.S. higher education. The commission soon confronted a problem: no extant classification system differentiated colleges and universities along the…
