The present study examined whether a sample of 214 (52.8% male, M age = 15.76, SD = 1.29) institutionalized adolescents could be classified into subgroups based on psychopathic traits. Confirmatory Factor Analyses revealed a relationship between the subscales of the Youth Psychopathic traits Inventory (YPI) and the three latent constructs of the…

Obsessive-compulsive disorder (OCD) is a chronic and impairing clinical disorder in childhood, often characterized by a heterogeneous symptomatic profile and high co-occurrence with other disorders. The present study introduces a new perspective on the description of OCD symptoms in youth, and empirically examines the value of a personality…

The ability to categorize problems based upon underlying principles, rather than surface features or contexts, is considered one of several proxy predictors of expertise in problem solving. With inspiration from the classic study by Chi, Feltovich, and Glaser, we assess the distribution of expertise among introductory physics students by asking…

School superintendents annually need to gain affirmative votes from their governing bodies to approve their district budgets. This paper proposes a framework through which the superintendent can express the district's educational needs and concomitant resource allocations in conceptual terms rather than in multi-columned ledgers. The framework…

The contribution of HBCUs as "colleges of origin," i.e., where Black doctorates earned their bachelors' degrees, remains of interest, given the historical role of HBCUs and the current desire to increase the percentage of doctorates awarded to African Americans in all fields. Using national survey data from multiple sources, we estimated…

Vocabulary development is a critical goal for early childhood education. However, it is difficult for researchers and teachers to determine whether this goal is being met, given the limitations of current assessment tools. These tools tend to view word knowledge dichotomously--as right or wrong. A clear sense of children's depth of semantic…

The one-parameter logistic model with ability-based guessing (1PL-AG) has been recently developed to account for effect of ability on guessing behavior in multiple-choice items. In this study, the authors developed algorithms for computerized classification testing under the 1PL-AG and conducted a series of simulations to evaluate their…

A contrast category effect on categorization occurs when the decision to apply a category term to an entity not only involves a comparison between the entity and the target category but is also influenced by a comparison of the entity with 1 or more alternative categories from the same domain as the target. Establishing a contrast category effect…

This article details a multi-modal active learning experience to help students understand elements of social categorization. Each student in a group dynamics course observed two groups in conflict and identified examples of in-group bias, double-standard thinking, out-group homogeneity bias, law of small numbers, group attribution error, ultimate…

Forecasting of ethnolinguistic vitality can only be done within a well-functioning descriptive and explanatory model of the dynamics of language stability and shift. It is proposed that the Perceived Benefit Model of Language Shift, used with a taxonomy of language shift motivations, provides that model. The model, based on individual language…

There are substantial reports on working-class student non-completion and the challenges of engaging or not with the teaching in higher education. The students in our study were all successful at university but the different universities provided different types of experiences for their respective students. In this paper we focus on the pedagogic…

Over the last two decades, moves toward "inclusion" have prompted change in the formation of education policies, schooling structures and pedagogical practice. Yet, exclusion through the categorisation and segregation of students with diverse abilities has grown, particularly for students with challenging behaviour. This paper considers…

Cognitive diagnostic models (CDMs) attempt to uncover latent skills or attributes that examinees must possess in order to answer test items correctly. The DINA (deterministic input, noisy "and") model is a popular CDM that has been widely used. It is shown here that a logistic version of the model can easily be fit with standard software for…

Early acquired words are processed faster than later acquired words in lexical and semantic tasks. Demonstrating such age of acquisition (AoA) effects beyond reasonable doubt, and then investigating those effects empirically, is complicated by the natural correlation between AoA and other word properties such as frequency and imageability. In an…

This article reviews recent literature on student financial aid as a retention tool at community colleges. Enrollment and tuition data from the National Center for Education Statistics (NCES) Integrated Postsecondary Education Data System (IPEDS), and federal direct grant student aid data from the IPEDS Student Financial Aid Survey are used to…
