Science has a role to play in the resolution of many of the issues deemed controversial in all societies. However, evidence of a lack of public confidence in science and scientists as effective problem‐solvers continues to accumulate. This paper speculates that this lack of confidence might in part be due to the way in which science educators present controversial issues. In particular, we argue that current approaches to teaching about controversy do not sufficiently acknowledge the nature of the issues themselves. The paper proposes a set of principles as the basis for a reconceptualization of the teaching of controversial issues and gives an example of how they might be applied.  相似文献

Judges' Use of Examinee Performance Data in an Angoff Standard‐Setting Exercise for a Medical Licensing Examination: An Experimental Study     

Brian E. Clauser  Janet Mee  Su G. Baldwin  Melissa J. Margolis  Gerard F. Dillon 《Journal of Educational Measurement》2009,46(4):390-407

Although the Angoff procedure is among the most widely used standard setting procedures for tests comprising multiple‐choice items, research has shown that subject matter experts have considerable difficulty accurately making the required judgments in the absence of examinee performance data. Some authors have viewed the need to provide performance data as a fatal flaw for the procedure; others have considered it appropriate for experts to integrate performance data into their judgments but have been concerned that experts may rely too heavily on the data. There have, however, been relatively few studies examining how experts use the data. This article reports on two studies that examine how experts modify their judgments after reviewing data. In both studies, data for some items were accurate and data for other items had been manipulated. Judges in both studies substantially modified their judgments whether the data were accurate or not.  相似文献   

Identity and Culture: theorising emergent environmentalism     

Justin Dillon  Elin Kelsey  Ana Maria Duque‐Aristizabal 《Environmental Education Research》1999,5(4):395-405

This article critically examines the methodology and findings of the emergent environmentalism research project as reported in Environmental Education Research (EER), 4(4). We challenge both the ontological stance implicit in the research as well as its explicit epistemology. We argue for a wider theoretical underpinning to the research and specifically advocate the use of identity theories to explain personal and social phenomena. We also argue for the use of theoretical frameworks that empower rather than ‘capture’ cultural groups.  相似文献   

The Images for Teaching Education Project: developing multimedia resources within an integrative educational framework     

Patrick Dillon  Penni Tearle  & Alison Hudson 《British journal of educational technology : journal of the Council for Educational Technology》1999,30(4):359-367

The University of Exeter heads a consortium which has developed multimedia resources primarily for initial teacher education. Amongst a range of resources produced are Critical Encounters in Secondary Education , which deals with critical incidents in the classroom and how to deal with them, Multimedia in the Learning Environment , which deals with both the nature of multimedia and how it may be used in support of a range of approaches to teaching and learning and English Chalklands which deals with interpretational and judgemental responses to landscape. The resources are described and discussed in the context of the educational framework which has been developed to guide their use.  相似文献

Using questions to foil discussion   总被引：1，自引：0，他引：1  

J.T. Dillon 《Teaching and Teacher Education》1985,1(2):109-121

Case studies of five high school classrooms illustrate the general proposition that teacher questions foil discussion, whereas nonquestion alternatives foster discussion. Even where conditions are favorable, questions are seen to forestall an emergent discussion or to frustrate it. By contrast, students in discussions of every kind speak more extensively in response to teacher statements and exhibit more complex thought, deeper personal involvement, wider participation, greater interconnectedness, and richer inquiry. This general case ought to be tested in research and tried in classroom practice, so that our understanding of questions will become more informed and our discussions more educative.  相似文献   

Young Children's Use of Surface and Object Information in Drawings of Everyday Scenes          下载免费PDF全文

Moira R. Dillon  Elizabeth S. Spelke 《Child development》2017,88(5):1701-1715

Pictorial symbols such as photographs, drawings, and maps are ubiquitous in modern cultures. Nevertheless, it remains unclear how children relate these symbols to the scenes that they represent. The present work investigates 4‐year‐old children's (N = 144) sensitivity to extended surface layouts and objects when using drawings of a room to find locations in that room. Children used either extended surfaces or objects when interpreting drawings, but they did not combine these two types of information to disambiguate target locations. Moreover, children's evaluations of drawings depicting surfaces or objects did not align with their use of such information in those drawings. These findings suggest that pictures of all kinds serve as media in which children deploy symbolic spatial skills flexibly and automatically.  相似文献   

The Role of Agricultural Education and Extension in Influencing Best Practice for Managing Mastitis in Dairy Cattle     

E. J. Dillon  T. Hennessy  J. Cullinan 《The Journal of Agricultural Education and Extension》2016,22(3):255-270

Purpose: To examine the role of agricultural education and extension in influencing the adoption of best practice with regard to herd-level mastitis management.Design/Methodology/Approach: Somatic cell count (SCC) is an indicator of herd health with regard to mastitis and is negatively related to productivity and profitability. Panel data regression methods are utilised here to quantify the role of agricultural education and extension in reducing cell count and in influencing farmer best practice with regard to herd health. The impact of education and extension on farmer uptake of milk recording is of particular interest. Data utilised is farm-level Farm Accountancy Data Network (FADN) data for Ireland over a five-year period (2008–2012).Findings: Farmer uptake of formal agricultural training and liaison with agricultural extension services are shown to significantly improve mastitis herd health. Collectively, education, extension and milk recording results in an overall SCC reduction of 25% for the average herd. Farmers who undertook agricultural training were ten times more likely to monitor milk quality through milk recording compared to those who had not. Additionally, those farmers in contact with an extension service and also participated in a dairy discussion group were seven times more likely to practice milk recording.Practical Implications: The importance of farmer behaviour in the optimum management of herd health has been validated, as has the role of agricultural education and extension in influencing the uptake of best practice by farmers.Originality/Value: To date little research has been conducted using nationally representative herd-level data on the role of agricultural education and extension in improving animal health best practice.  相似文献
