The Nonprofit Program Classification System being developed by the National Center for Charitable Statistics (NCCS) provides a way to enrich the information available on nonprofits and utilize the newly available NCCS/PRI National Nonprofit Organization database from the IRS Forms 990 filed annually by charities. It provides a method to organize…

From Aesop to Sun Tzu, the importance of working together has long been acknowledged. Yet as long as cooperation has existed, so have the difficulties associated with it. Pooling two fields might mean twice the power, but this union also brings twice the jargon, twice the competing theories, and twice the head butting. Nonetheless, in this…

Young infants are very sensitive to feature distribution information in the environment. However, existing work suggests that they do not make use of correlation information to form certain perceptual categories until at least 7 months of age. We suggest that the failure to use correlation information is a by-product of familiarization procedures…

Learning communities (LC) seek to strengthen and enrich students' connections to each other, their teachers, and the subject matter they are studying. Their success depends on the nature of the learning community program, the learning styles of the students who participate and the reasons why students entered the program. This study uses a…

The double-deficit hypothesis of developmental dyslexia proposes that deficits in phonological processing and naming speed represent independent sources of dysfunction in dyslexia. The present article is a review of the evidence for the double-deficit hypothesis, including a discussion of recent findings related to the hypothesis. Studies in this…

This article discusses the author's observation that in his thirty-plus years in academics, many students who, by natural ability, interest, and work ethic, should have performed well in the sciences, but performed poorly. Many of these students are operating at the bottom rungs of Bloom's taxonomy (ladder), while college professors and industrial…

Issues relating to the categorisation and labelling of pupils, and, the use of the terms "special educational needs" and "disability" in particular, have been the topic of debate in "BJSE" before. In this article, Sue Keil, a research officer at the Royal National Institute for the Blind (RNIB), Olga Miller, of the…

The literature on facilitation describes the skills, methods, models and theories of facilitation but gives less coverage to the assumptions and philosophies that underpin the processes by which facilitators develop. This paper reviews the literature on facilitation and provides a typology, which classifies the different approaches to facilitator…

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…
