Classification "rules" in expert and everyday discourse are usually deficient by formal standards, lacking explicit decision procedures and precise terms. The authors argue that a central function of such weak rules is to focus on perceptual learning rather than to provide definitions. In 5 experiments, transfer following learning of family…

This article describes the construction of a hierarchical taxonomy of metacognitive activities for the interpretation of thinking-aloud protocols of students in secondary education, who studied texts on history and physics. After testing an initial elaborate taxonomy on a restricted number of protocols by multiple raters, it appeared that the…

The effects of five ability estimators, that is, maximum likelihood estimator, weighted likelihood estimator, maximum a posteriori, expected a posteriori, and Owen's sequential estimator, on the performances of the item response theory-based adaptive classification procedure on multiple categories were studied via simulations. The following…

This study used the Measure of Epistemology Reflection to explore the impact of service-learning and social justice education on college students' cognitive development. Six service-learning courses taught with or without a social justice emphasis were studied. Results showed that service-learning courses in general had a positive impact on…

Similarity underlies fundamental cognitive capabilities such as memory, categorization, decision making, problem solving, and reasoning. Although recent approaches to similarity appreciate the structure of mental representations, they differ in the processes posited to operate over these representations. We present an experiment that…

The objectives of this study were to generate precise estimates of suicide rates in the military while controlling for factors contributing to rate variability such as demographic differences and classification bias, and to develop a simple methodology for the determination of statistically derived thresholds for detecting significant rate…

Much of the literature on charter schools treats them as an undifferentiated mass. Here we present and test a typology of charter schools that is grounded in the norms, traditions, and perspectives of the founding organization or organizers. We suggest that there are two broad categories of charter founders--those who are more mission oriented and…

In 1997, the Office of Management and Budget revised guidelines for treatment of racial and ethnic data, adding a requirement to allow respondents to indicate more than one race and mandating a change in all federal data collection and reporting by January 1, 2003. Nearly 2 years after the deadline for implementation, however, higher education…

Researchers, practitioners and theorists have raised concerns about the special education delivery and classification processes in the United States. The President's Commission on Excellence in Special Education report (PCESE:2002) examined these concerns and existing special education research, reports and opinions to develop recommendations for…

In this literature review, the author focuses on several ethical considerations in case conceptualization and diagnosis, including diagnostic training and competence. Meeting the American Counseling Association's (1995) ethical standard for diagnostic training has several ethical implications for counselors, counselor educators, and supervisors.…

This article reviews the "Diagnostic and Statistical Manual of Mental Disorders-Forth Edition-Text Revision" and compares and contrasts the diagnostic criteria for individuals with autism with the educational requirements under the Individuals with Disabilities Education Act. Problems with using a dual classification system are…

This study surveyed 165 care professionals on their experience of workplace bullying. The results showed that in a 2-year period 40% had been bullied and 68% had observed bullying taking place. Of the 67 care professionals that had been bullied 44% were experiencing high levels of PTSD symptoms based on the general factor of the IESE. However,…

In this study, the authors used meta-analytical techniques to examine the relationship between personality and entrepreneurial status. Personality variables used in previous studies were categorized according to the five-factor model of personality. Results indicate significant differences between entrepreneurs and managers on 4 personality…

Three studies (N = 171) examined preschool children's tendency to use category information to make inferences about ambiguous behavior. Children heard stories in which category information about story characters was manipulated and behavioral information was held constant. Participants were asked to evaluate, explain, and determine the…

Articles about the pendulum in four journals devoted to the teaching of physics and one general science teaching journal (along with other miscellaneous articles from other journals) are listed in three broad categories--types of pendulums, the contexts in which these pendulums are used in physics teaching at secondary or tertiary levels and a…
