Formulae are derived for the deflection surface of a symmetrically loaded circular plate having several points supports which are situated at equal distances apart on a single concentric circle. There is no restriction on the diameter of the support circle, which may be as large as the diameter of the plate itself. The results of this paper compare favorably with published experimental results. Numerical deflection coefficients for a uniformly loaded plate are provided, and these could be utilized for optimizing the positions and the number of concentrated supports. 相似文献

The development of support staff was a key aspect of the Labour government’s reform of the school workforce in England. As part of this strategy approximately 25,000 Teaching Assistants (TAs) gained Higher Level Teaching Assistant (HLTA) status and were deployed in schools in a variety of roles, often operating in a quasi-teaching role. The research re-visits individuals who had acquired HLTA status between 2006 and 2009 and had participated in a questionnaire survey regarding their role at that time. A duplicate questionnaire was distributed in 2013 to 305 of these HLTAs and was followed up in 2014 by focus groups with self-selecting individuals from the original sample. To date there has been little research relating to the development of the HLTA role and the implications this has for both teachers and pupils, particularly in terms of provision for the most vulnerable learners. 相似文献

In two experiments, participants made inferences from weather maps, before and after they received instruction about relevant meteorological principles. Different versions of the maps showed either task-relevant information alone, or both task-relevant and task-irrelevant information. Participants improved on the inference task after instruction, indicating that they could apply newly acquired declarative knowledge to make inferences from graphics. In Experiment 1, participants spent more time viewing task-relevant information and less time viewing task-irrelevant information after instruction, and in Experiment 2, the presence of task-irrelevant information impaired performance. These results show that domain knowledge can affect information selection and encoding from complex graphics as well as processes of interpreting and making inferences from the encoded information. They also provide validation of one principle for the design of effective graphical displays, namely that graphics should not display more information than is required for the task at hand. 相似文献

This article considers in a wide perspective the crisis in the assessment of examinations in A‐level English Literature and current attempts to address the problems. Examining the implications of a survey of recent reports initiated by the regulator, it argues that trying to ensure reliability merely through technological advances and changes in examining practice obscures the need for English teachers’ communal understanding of academic standards to be developed through their professional experience. It proposes ways in which this should be achieved, for example by developing current and potential professional networks and communities of practice. 相似文献

A Hunter College librarian, with public library experience, offered a series of drop-in workshops Saturday afternoons open to all students and questions regarding Web or Windows use in the academic year, 2000-2001. The intention of the workshops was to address the continuous needs of students lacking technological and informational literacy. The success of these workshops led to this investigation of the implications of 21st century technology on non-traditional students from the perspective of bibliographic instruction as well as reference desk service. The perspective is that of the urban educational environment of City University of New York and Hunter College. The histories of open admissions at CUNY and the current efforts to abolish remediation are examined. 相似文献
