This study focused on foundational aspects of classroom relations. Specifically, relationships between teachers’ immediacy (interpersonal) behaviours, classroom democracy, identification and learning were considered. Previous work suggests that these variables can be used as a foundation to shape classroom climate, culture and learning outcomes and, by extension, assist educational institutions to achieve their civic mission. This study examined classroom democracy and class identification as variables that mediate the relationship between immediacy behaviours and learning using data collected from 529 students in six institutions of higher learning in Rwanda. Structural equation modeling revealed that classroom democracy mediates the relationship between immediacy behaviours and that classroom democracy and class identification covary substantially. The significant relationships in the final structural model suggest that immediate teachers are likely to have a positive influence on perceptions of classroom democracy, class identification and learning. Based on the growing scholarship of instructional dissent, this study highlights the foundational and strategic aspects underlying these relationships within the context of relating in the classroom and beyond. 相似文献
A semi-analytical Monte Carlo (SMC) simulation was developed to simulate the propagation of laser-induced fluo- rescence (LIF) in an optically participating spray, which simultaneously exhibits spectrally dependent emission, anisotropic scattering, absorption, and re-emission. The SMC simulation is described and then applied to an experimental configuration of a cloud of polydisperse droplets composed of water and sulforhodamine B dye. In the SMC simulation, the collected LIF flux on the remote receptor element is calculated as the global contribution from the emissive source, single, twice, … and nth collision events in any sequence. The effects on the fluorescence photons propagation of spray parameters like the dye concentration, droplets concentration, and droplets size are examined. Three spectral bands representing different optical properties are chosen to analyze the interference of absorption, scattering and re-emission on the detected LIF flux. The obtained spectral LIF flux distribution on the receptor demonstrates a “red shift” phenomenon. 相似文献
Drawing upon the literature of business management, the authors develop an approach to the problems of managing the large research laboratories which have now become more common but which have to exist in the changed climate of the 1980s. The types of managerial problems which arise are classified, the politics of their management analysed and the form in which these problems manifest themselves is discussed. It is concluded that those who have charge of large laboratories must be determined to implement what the authors describe as strategic practice if the laboratories are to function efficiently. 相似文献
Discriminative stimuli produced by drugs control behavior in the same way as exteroceptive discriminative stimuli control behavior, despite the difficulty in controlling the intensity of the discriminative stimulus properties of drugs throughout test sessions. In recent years, many investigators have correlated the potency of drugs as discriminative stimuli, with their affinity for specific pharmacological receptors. High correlations have been interpreted as evidence that the discriminative stimulus properties of drugs are mediated by these specific pharmacological receptors. However, the relationship between discriminative stimulus potency and receptor affinity can be confounded by other pharmacological effects of drugs, such as their ability to produce position responding, and by behavioral variables, such as the schedule of reinforcement under which the drug discrimination is established and measured. 相似文献
The large number of secondary school graduates entering higher education is transforming the nature of universities, particularly in literature and the humanities, by changing the relative numbers of students enrolled in different academic years. At the same time this influx is accompanied by a significant failure rate in the first academic year, calling into question the efficacy of the university system. A national issue with local repercussions, the struggle against failure in the first year is leading to much heart-searching among the universities, whose staff are trying hard to understand why certain students abandon their studies. The enquiry described in this article reveals the co-existence of two student populations: those who enter university as an active choice and those who do so by default. In the case of the first group, entry to university represents an investment for the future which must be carefully managed. In the second case it is a matter of going into higher education as a faute de mieux solution in an economic context in which work is scarce. 相似文献
Diversity is what makes a person unique, with the intersection of diversity characteristics potentially a strength or a barrier to accessing healthcare, and thereby affecting health and well-being outcomes. Many older people with diverse needs are not accessing appropriate services to meet their needs, leading to suboptimal health and well-being. Community aged care workers are at the frontline, working with diverse older people with complex needs; yet there is a dearth of training available in this sphere. This paper outlines the development and pilot evaluation of a diversity training workshop for managers and frontline community aged care workers. The aim of the workshop was to empower the workforce to support increased participation of older people with diverse needs in their own care, to ultimately lead to their improved health and well-being.
Workshop development was underpinned by sound education principles, a competency framework and research evidence. First iteration of the workshop underwent pilot testing with three groups, two in metropolitan Melbourne (n = 31) and one in regional Victoria (n = 10), Australia. Feedback was gathered via an independent observer (field notes), pre- and post-workshop surveys, and phone interviews with participants 3-month post-workshop. Pilot data and feedback informed changes to workshop content (type of knowledge, application of knowledge and skills), workshop structure and androgogical (adult learning) approach.
An evidence-informed diversity training workshop was developed through an iterative process, with the aim of enhancing knowledge, skills and attitudes of community aged care workers. This approach has developed a workshop that aims to better meet the needs of an aged care workforce, so that they may better support older people with diverse needs to increase engagement and participation in their care, optimizing their health and well-being. 相似文献
