This article presents a model for designing student-centered, technology-rich learning environments (SCenTRLE). The model helps educators operationalize constructivist and student-centered approaches to teaching and learning by delimiting eight instructional events for facilitating knowledge construction and the development of life-long learners. The article describes theoretical and conceptual...

A large body of research documents cognitive differences between Westerners and East Asians. Westerners tend to be more analytic and East Asians tend to be more holistic. These findings have often been explained as being due to corresponding differences in social orientation. Westerners are more independent and Easterners are more interdependent. However, comparisons of the cognitive tendencies...

Motivation In a scienceand risk-based food safety system, decision makers must utilize the best available data to determine the greatest risks to public health and to prioritize interventions to reduce these risks. This requires understanding the many factors that can contribute to the causation and prevention of foodborne illness from the point of production to the point of consumption and bei...

The small acmaeid limpet Patelloida lat istr~gata Angas and clumps of macroalgae are found in midshore intertidal regions dominated by barnacles. Interactions between limpet and algae were investigated experimentally to determine the effect of the herbivore on microalgae (this term includes propagules of macroalgae) as well as on macroalgal plants, and also the influence of both forms of algae ...

This study examined solution strategies and gender differences in a Spatial Visualization (Vz) task. Two kinds of strategies, analytic and holistic or spatial manipulation, were operationalized by a self-report questionnaire and three time based variables obtained in a comp uterized form board task, the R-E. The variables were: time of initial encoding of the target stimulus, duration of proces...

The evaluation of writing ability of L2 students has become increasingly important in recent years, because the results of such evaluations are used for a variety of administrative, instructional, and research purposes. One of the first decisions to be made in determining a system for directly assessing writing quality is what type of scoring procedure will be used: Should a single score be giv...

When eliciting probability models from experts, knowledge engineers may compare the results of the model with expert judgment on test scenarios, then adjust model parameters to bring the behavior of the model more in line with the expert's intuition. This paper presents a methodology for analytic computation of sensitivity values to measure the impact of small changes in a network parameter on ...

CONTEXT The National Board of Osteopathic Medical Examiners uses the Osteopathic Manipulative Treatment (OMT) Global Rating Tool to score candidate performance in OMT during standardized patient encounters. To the authors' knowledge, no validity research has been published on the underlying constructs measured by this instrument to date. OBJECTIVE To evaluate whether the OMT Global Rating Too...

BACKGROUND Numerous studies have explored the effectiveness of complementary and alternative medicine in the treatment of migraine but there is no documented investigation of the effectiveness of yoga therapy for migraine management. OBJECTIVES To investigate the effectiveness of holistic approach of yoga therapy for migraine treatment compared to self-care. DESIGN A randomized controlled t...
