Bayesian networks are frequently used in educational assessments primarily for learning about students' knowledge and skills. There is a lack of works on assessing fit of Bayesian networks. This article employs the posterior predictive model checking method, a popular Bayesian model checking tool, to assess fit of simple Bayesian networks. A…

There have been a great many good and varied textbooks in the history of education. For example, there was L.F. Magnitskii's "Arithmetic," L.N. Tolstoy's "Primer," and the Bible, which can also be thought of as a textbook. None of them is like the others at all. Each one is suitable for dealing with its own objectives in the…

This article presents three research methods--Think Alouds, Think Afters, and Think Togethers--as ways of gathering data to describe the experiences of adolescents during instructional activities. These verbal report methods were used in two studies that examined the information-seeking processes of adolescents in Inuvik, Northwest Territories and…

Writing development involves changes that occur in children's strategic behavior, knowledge, and motivation. The authors examined the effectiveness of self-regulated strategy development (SRSD), a strategy instructional model designed to promote development in each of these areas. Instruction focused on planning and writing stories and persuasive…

This study sought to address the lack of experimental research examining the influence of contextual factors on African American students' learning. A total of 162 low-income African American and White fourth graders were randomly assigned to ethnically homogeneous, communally structured groups of three to work on a motion acceleration task using…

Objective: Although many studies have identified associations between childhood maltreatment and later substance use and disordered eating, few have examined causal or explanatory pathways, and whether victim characteristics predict the development of one versus the other of these outcomes remains uninvestigated. Furthermore, relatively little…

Background: Several theorists maintain that exact number abilities rely on language-relevant processes whereas approximate number calls on visuo-spatial skills. We chose two genetic disorders, Williams syndrome and Down's syndrome, which differ in their relative abilities in verbal versus spatial skills, to examine this hypothesis. Five…

The mathematics achievement levels of U.S. students fall far behind those of other developed nations; within the United States itself, the students who are falling behind come predominantly from high-poverty and high-minority areas. This article reports on a series of analyses that followed 4 cohorts of students from 3 such schools through the 5th…

The expansion in the number of people entering higher education has resulted in a substantial increase in the proportion of students enrolling in nontraditional modes, such as part-time study. This study examined the question of whether part-time study curtails the development of the types of intellectual capabilities needed for a knowledge-based…

A conceptual model was developed in an urban undergraduate education institution in the US to assess teaching performance and intellectual development levels of teacher candidates. Danielson's framework of teaching performance and Perry's pattern of intellectual and ethical development were used for developing a conceptual model. A pilot study was…

This study analyzes structural forces affecting state patterns of parental presence within grandparent-grandchild coresidence by testing demographic, social change, policy environment, and social problems models. The project combines published state-level data with the 1970, 1980, and 1990 Census Public Use Microdata Samples. While factors…

This article is the second part of a report on research that examined immersion language teachers' strategies to modify their speech in order to maintain use of the target language. As described in the first part in "Babel," Volume 40, Number 2 (Veque, 2005), this classroom-based research, undertaken at Methodist Ladies College (MLC) in…

While team mental models have been shown to be effective in facilitating team operations in ordinary transactive organizations, their impact on loosely coupled yet value-laden organizations is relatively under studied. Using qualitative inquiry methodology, this study investigates the three referential frameworks (i.e., theoretical knowledge,…

This paper presents a service-learning approach to inner city revitalization that is grounded in a human capital model for economic development. The case study demonstrates how a private university became the catalyst for growth in an "at risk" neighborhood of an urban inner city. Our ongoing service-learning project, called The Upper…

In the accessible e-learning community there are very few original metaphors, theories and models that have been developed to try and describe, explain and develop "best" practice. This paper will explore the extent to which existing accessibility models can help to develop our conceptualisations of accessible e-learning practice, and outline a…
