Introductory business statistics students often receive little guidance on how to apply the methods they learn to further business objectives they may one day face. And those students may fail to see the continuity among the topics taught in an introductory course if they learn those methods outside a context that provides a unifying framework. The DCOVA problem‐solving framework that presents discrete steps to define, collect, organize, visualize, and analyze data addresses these concerns while helping to enhance the perceived value of taking statistics courses. 相似文献

Environmental field days offer a distinct opportunity to connect students with science and the environment. The literature on field days, informed by research on field trips, provides a framework for best practices. If there are best practices, however, then presence or lack of the practice should have a discernable impact on the outcomes of the field day and should be measurable and some of them should be observable. The Delphi process was modified to ground the theory and to end the Delphi using a subset of the panel in a face‐to‐face meeting to move from consensus to instrument construction. This paper describes the process and shows a summary of the findings of each of the rounds of the Delphi. The use of a Delphi method for determining consensus around the validity of the theory emerging from the research and literature on field days was appropriate and shows that this type of testing against grounded theory can prove useful for building measures to test the emergent theoretical constructs. Modifying the Delphi to focus on the theoretical constructs emerging from the initial analysis allowed the process to function as a true Delphi and eliminated the long process of construct identification. 相似文献

Electronic assistance devices for visually impaired people often require pedestrian detection functionality. Due to the fact that these devices have only low computational processing capabilities, it is necessary to use realtime algorithms that meet these requirements.We thus propose application of a cascaded support vector machine (SVM) classifier with linear and combined cascading of SVMs based on histogram of oriented gradients (HOGs) and Fisher score preselection. Proposed algorithms are evaluated on the basis of the INRIA database and compared to the state of the art procedure with HOG-features in combination with a standard SVM. 相似文献

As executive functions play an essential role in learning processes, approaches capable of enhancing executive functioning are of particular interest to educational psychology. Recently, the hypothesis has been advanced that executive functioning may benefit from changes in neurobiological processes induced by physical activity. The present research explored this hypothesis by systematically identifying and reviewing intervention studies targeting the relationship between physical activity and executive functions, distinguishing between different types of intervention and of executive function. The review found considerable evidence for beneficial effects of physical activity on executive functions, with performance benefitting more consistently in inhibition tasks than in dual task coordination, shifting tasks, or combined tasks. Possible physiological explanations are discussed. Open questions for application and future research concern the sustainability of effects, the design of physical activity interventions, and the role of individual differences. Possible interventions applicable to educational settings are discussed. 相似文献
