Using observation of teaching to improve quality: finding your way through the muddle of competing conceptions,confusion of practice and mutually exclusive intentions     

Tim McMahon  Terry Barrett  Geraldine O'Neill 《Teaching in Higher Education》2013,18(4):499-511

This paper begins by reviewing some of the different models of third-party observation of university teaching that can be found in the literature. Having analysed these, it argues that—if ‘peer’ is taken to indicate equality of status—only one is genuinely a model of peer-observation. It proposes an alternative categorisation of third-party observations of teaching dependant on who controls the information generated by the process. A preferred six-dimensional model based on control by the person being observed of the data-flow, and other procedural aspects, is presented and explored. Evaluative comments, by university teachers who have undertaken the process, are presented to illustrate the benefits of adopting this model.  相似文献   

Diagnosis,Evaluation, and Treatment of Lead Poisoning in General Population     

D'souza HS  Dsouza SA  Menezes G  Venkatesh T 《Indian journal of clinical biochemistry : IJCB》2011,26(2):197-201

Among the heavy metals, lead still remains the major toxic pollutant of the environment. Human exposure to lead can occur through numerous pathways including air, food, dust, soil, and water. In the present study 14 lead poisoned patients with non-occupational lead exposure were evaluated. They were followed up and compared against the controls with no history of lead exposure. The patients had high blood lead levels and symptoms of weakness, dizziness, abdominal pain, generalized body ache, loss of appetite, and anxiety. Repeated course of chelation therapy helped to bring down their body burden of lead. Alternative sources for lead exposure can cause severe lead poisoning in general population. Screening and medical management of such individuals is very important to identify and eliminate sources of lead. The treatment and management requires a thorough medical evaluation and environmental intervention.  相似文献   

A robust unscented transformation for uncertain moments     

Hugo T.M. Kussaba  João Y. Ishihara  Leonardo R.A.X. Menezes 《Journal of The Franklin Institute》2019,356(6):3797-3810

This paper proposes a robust version of the unscented transform (UT) for one-dimensional random variables. It is assumed that the moments are not exactly known, but are known to lie in intervals. In this scenario, the moment matching equations are reformulated as a system of polynomial equations and inequalities, and it is proposed to use the Chebychev center of the solution set as a robust UT. This method yields a parametrized polynomial optimization problem, which in spite of being NP-Hard, can be relaxed by some algorithms that are proposed in this paper.  相似文献

What can age by grade tell us about education in Australia?     

Geraldine McDonald 《The Australian Educational Researcher》2001,28(1):81-105

The education systems in the States and Territories of Australia are analyzed using age by grade (Year) tables produced by the Australian Bureau of Statistics from the 1 July returns from government and nongovernment schools. The demographic patterns of 8-year-olds at Year levels show that the system of promotion through school and the rates of retention in the early years differ by State and Territory. The factors producing these variations are explored. Indigenous/non-indigenous differences in school progress are uneven across States and Territories and there are small differences favoring girls. Policy implications for the findings are discussed.  相似文献   

Towards a codification of practical knowledge     

Géraldine?RixEmail author  Pascal?Lièvre 《知识管理研究与实践》2008,6(3):225-232

As practical knowledge seems to have a central place in organisational issues, we focus on possibilities of studying and formalising it. From an unusual theoretical perspective, we view practical knowledge as embodied knowing that is only manifest through action in a particular situation. Although this knowledge is largely implicit, we try to make what is articulable explicit. After highlighting the stakes involved in the codification of practices, we review the ontological and epistemological assumptions underlying the method developed. The method is founded on participant observation, a video recording of a situated subjective perspective and an ex post interview using this perspective to aid an actor in making part of his/her practical knowledge explicit. We present its implementation within research on polar expeditions in order to understand how an experienced actor deals with risks. In conclusion, we point out (1) the importance of this kind of data in knowledge management, (2) some lines of further research.  相似文献

The relation between self-regulation and the embedding of support in learning environments     

Geraldine Clarebout  Holger Horz  Wolfgang Schnotz  Jan Elen 《Educational technology research and development : ETR & D》2010,58(5):573-587

The current study investigates whether embedding support may provide a solution to sub optimal use of support and whether this is related to learners’ self-regulation skills and goal orientation. Sixty students were divided in a condition where support was embedded and a condition where support was non-embedded. Results reveal that the embedded group used more and spent more time on the use of support. Quality of use differed for one support device only, with quality being higher in the non-embedded group. An interaction with self-regulation was found. High self-regulators use the support devices less optimal when support is embedded. No conclusions could be drawn with respect to goal orientation. Quality of usage and proportional time spent on support influenced learning outcomes.  相似文献   

English as a foreign language,globalisation and conceptual questioning   总被引：1，自引：1，他引：0  

Clarissa Menezes Jordão 《Globalisation, Societies & Education》2009,7(1):95-107

This text discusses the locus of English in globalisation discourses. Assuming that languages constitute discursive formations informing ways of knowing, discourses of English as a global language (EGL) are positioned in relation to teaching English as a foreign language in the glocal scene. We draw on post‐colonial theories and critical education, treating languages as social practices and conceiving of teaching EGL as a privileged context for discursive agency, especially when discourses of global English are critically engaged with through dialogue and conceptual questioning. We present a post‐method suggestion of procedures to promote conceptual questioning through construction of open spaces.  相似文献   

The risk is that there is ‘no risk’: a simple,innovative intervention to increase children’s activity levels     

Anita C. Bundy  Tim Luckett  Paul J. Tranter  Geraldine A. Naughton  Shirley R. Wyver  Jo Ragen 《International Journal of Early Years Education》2009,17(1):33-45

School playgrounds offer everyday opportunities for physically active and social play that combats obesity, develops skills, and promotes well‐being. However, teachers’ fear of the legal consequences of injury can elicit over‐zealous risk reduction with the result that playgrounds lack challenge, and the potential benefits of play become limited. In this research, we trialled a simple, cost‐effective strategy to encourage children to be more active and social on a school playground. Over 11 weeks, we made available materials with no fixed purpose (e.g. car tires, boxes) to a playground of children aged five to seven. Accelerometers showed children became significantly more active. Interviews with teachers suggested children also became more social, creative, and resilient. However, despite no incidence of injuries, teachers perceived an increased risk and encountered dilemmas regarding duty of care. We conclude that future interventions should address issues of ‘surplus safety’ at individual, school, system, and policy levels.  相似文献
