Colleges of Business (COBs) have experienced high growth rates in the past decade and many colleges are imposing minimum grade point average (GPA) requirements for students to enter or remain in the college. A primary reason for this requirement may be the belief that students with high GPAs are more inclined to demonstrate higher‐order cognitive skills (HOCS) than students with low GPAs. It is not clear whether the link is valid. This study hypothesizes that students with high GPAs who are taught in the same way as students with lower GPAs will have higher perceptions of improved HOCS. We conducted an experiment in which students, with varying GPAs, at three large universities primarily used multimedia instructional materials. We obtained the students' perceptions of their improved HOCS from their responses to a survey. A regression analysis of the data reveals that the relationship between GPAs and students' perceived improvement in HOCS is significant (p < .001). We conclude the study by recommending that (a) it is critical to use research methodologies to evaluate perceived and actual learning improvements, (b) COB policies to implement GPA restrictions on admission are worthwhile, and (c) case studies need to be used much more frequently in undergraduate COB classes. 相似文献

This paper challenges the practical and conceptual understanding of the role of emotions in higher education from the twin perspectives of transition and transformation. Focusing on the neglected area of positive emotions, exploratory data reveal a rich, low-level milieu of undergraduate emotional awareness in students chiefly attributed to pedagogic actions, primarily extrinsically orientated, and pervasive throughout the learning experience. The data conceive positive affect as oppositional, principally ephemeral and linked to performative pedagogic endeavours of getting, knowing and doing. A cyclical social dynamic of reciprocity, generating positive feedback loops, is highlighted. Finally we inductively construct a tentative ‘emotion-transition framework’ to assist our understanding of positive emotion as a force for transformational change; our contention is that higher education might proactively craft pedagogic spaces so as to unite the feeling discourse, the thinking discourse (epistemological self) and the wider life-self (ontological) discourse. 相似文献

Abstract The Muslim community in Sri Lanka has a pre-Islamic origin. Ethnically they are a mixed group, but changing political fortunes throughout the course of Sri Lankan history have made them realize that their identity lies in holding fast to the religion of Islam and not to any ethnic category. The current Sinhala-Tamil ethnic war has once again reinforced the need to hold on to the religious identity even more tightly. However, recent economic and political changes in the country and changes taking place in the Muslim world have injected new concerns for the community to worry about. The community is well and truly trapped in a political quagmire. This article highlights some aspects of this predicament. 相似文献

Societal response to climate change has been inadequate. A perception that the issue is both physically and temporally remote may reduce concern; concern may also be affected by the political polarization surrounding the issue in the USA. A feeling of connection to nature or to animals may increase personal relevance, and a supportive social context may counteract political tensions. Zoos may provide opportunities for both sense of connection and social support. We surveyed over 7000 zoo and aquarium visitors to examine the ways in which a feeling of personal connection among zoo visitors may encourage concern about climate change. Results show that feeling connected to animals at the zoo is significantly associated with cognitive and emotional responses to climate change, as well as with other social groupings and social responses. Overall, the zoo seems to present a supportive social context for considering the topic. 相似文献

Mapping the Contours of Neoliberal Educational Restructuring: A Review of Recent Neo‐Marxist Studies of Education and Racial Capitalist Considerations 下载免费PDF全文
Clayton Pierce 《Educational theory》2015,65(3):283-298
In this article Clayton Pierce reviews three books representative of the recent neo‐Marxist literature on education: David Blacker's The Falling Rate of Learning and the Neoliberal Endgame, John Marsh's Class Dismissed: Why We Cannot Teach or Learn Our Way out of Inequality, and Pauline Lipman's The New Political Economy of Urban Education: Neoliberalism, Race, and the Right to the City. His analysis of these books focuses on how each author remains consistent or advances traditional Marxist interpretations of the role of education in capitalist society. In addition, he puts the arguments of each author into conversation with W. E. B. Du Bois's analysis of schooling in a racial capitalist society — what he called caste education — as a way to generate discussion around some of the inherent limitations of Marxist studies of education. Here, Pierce is particularly concerned with the ability of neo‐Marxist analyses of the neoliberal restructuring of education to articulate how white supremacy is preserved even in revolutionary critiques of capitalist schooling. 相似文献

This paper attempts to answer this question: what should ecoliteracy mean in a biocapitalist society? The author situates his analysis of this question within the general context of the neoliberal reconstruction of education in the US. Specifically, focus is given to the shared model of governmentality GE food industries and education policies both utilize to manage life in the field and classroom – one where optimizing the value of plants and people for ‘flat world’ economic competition is the defining goal. Given this landscape, I suggest that what some environmental educators have called ‘ecological literacy’ or ‘critical ecoliteracy’ must now include a dimension that rejects the ways both human and nonhumans are progressively being implicated into biocapitalist enterprises. I offer an example of how biocapitalist industries educate market understandings of life by looking at how the GE food industry’s educational projects attempt to teach students and the public to think of nature and themselves as entrepreneurial actors. In the final section, I provide an example from my research using actor network theory in learning gardens as a way to develop a theory and practice of ecoliteracy that is capable of identifying and resisting the ways both human and nonhuman life are being captured and reconstructed within biocapitalist development ventures. 相似文献

Finite-time stability involves dynamical systems whose trajectories converge to an equilibrium state in finite time. In this paper, we consider a general class of fully actuated mechanical systems described by Euler–Lagrange dynamics and the class of underactuated systems represented by mobile robot dynamics that are required to reach and maintain the desired trajectory in finite time. An approach known as the terminal sliding mode control (TSMC) involves non-smooth sliding surfaces such that, while on the sliding surface, the error states converge to the origin in finite time thus ensuring finite-time tracking. The main advantage of this control scheme is in fast converging times without excessive control effort. Such controllers are known to have singularities in some parts of the state space and, in this paper, we propose a method of partitioning the state space into two regions where the TSMC is bounded and its complement. We show that the region of bounded TSMC is invariant and design an auxiliary sliding mode controller predicated on linear smooth sliding surface for the initial conditions outside this region. Furthermore, we extend these results to address TSMC for underactuated systems characterized by the mobile robot dynamics. We demonstrate the efficacy of our approach by implementing it for a scenario when multiple dynamic agents are required to move in a fixed formation with respect to the formation leader. Finally, we validate our results experimentally using a wheeled mobile robot platform. 相似文献
