This paper reports an experimental evaluation of a children's safety training programme,Kidscape, which aims to increase primary school children's ability to deal with four types of potentially unsafe situation: being bullied, being approached by a stranger, being subject to inappropriate intimacy from a known adult and to pressure from such adults to keep such intimacy secret. Assessments of children's safety awareness were carried out in three schools which used the programme, and in three matched control schools which did not, with children at two age levels, 6 years and 10 years. These assessments of children's awareness were made on three occasions: before, immediately after and 2‐3 months after the training programme for the experimental sample (60 children) and on corresponding occasions for the control sample (60 children). The results revealed a significant improvement in the safety awareness of the experimental (trained) group after training and also a significant difference between the groups, in favour of the trained group. However, an improved performance of the control (untrained) group suggests that factors other than the Kidscape programme itself may influence these differences. Age differences in children's wariness of the four safety situations are also discussed.  相似文献   

Modifying Knowledge,Emotions, and Attitudes Regarding Genetically Modified Foods     

Benjamin C. Heddy  Robert W. Danielson  Gale M. Sinatra  Jesse Graham 《Journal of Experimental Education》2017,85(3):513-533

The purpose of this study was to explore whether conceptual change predicted emotional and attitudinal change while learning about genetically modified foods (GMFs). Participants were 322 college students; half read a refutation text designed to shift conceptual knowledge, emotions, and attitudes, while the other half served as a control group. The results suggest that the refutation text effectively facilitated change in conceptual knowledge, emotions, and attitudes. The hypothesized relationship among the variables was explored using structural equation modeling. The analysis showed that when participants experienced knowledge change toward more scientifically accepted conceptions of GMFs, their emotions became more positive and less negative, which predicted a subsequent shift toward more-positive attitudes. The results suggest that change in emotions mediates the relationship between conceptual and attitudinal change. Several theoretical and practical implications are discussed including the impact that these findings may have on science education.  相似文献   

University-level teaching of Anthropogenic Global Climate Change (AGCC) via student inquiry     

Drew Bush  Renee Sieber  Gale Seiler  Mark Chandler 《Studies in Science Education》2017,53(2):113-136

This paper reviews university-level efforts to improve understanding of anthropogenic global climate change (AGCC) through curricula that enable student scientific inquiry. We examined 152 refereed publications and proceedings from academic conferences and selected 26 cases of inquiry learning that overcome specific challenges to AGCC teaching. This review identifies both the strengths and weaknesses of each of these case studies. It is the first to go beyond examining the impact of specific inquiry instructional approaches to offer a synthesis of cases. We find that inquiry teaching can succeed by concretising scientific processes, providing access to global data and evidence, imparting critical and higher order thinking about AGCC science/policy and contextualising learning with places and scientific facts. We recommend educational researchers and scientists collaborate to create and refine curricula that utilise geospatial technologies, climate models and communication technologies to bring students into contact with scientists, climate data and authentic AGCC research processes. Many available science education technologies and curricula also require further research to maximise trade-offs between implementation and training costs and their educational value.  相似文献   

Teacher candidates’ epistemological beliefs, dispositions, and views on teaching as persuasion     

Gale M. Sinatra  CarolAnne M. Kardash 《Contemporary educational psychology》2004,29(4):21

Alexander and her colleagues proposed teaching as persuasion as a guiding metaphor for conceptual change pedagogy (Alexander, Fives, Buehl, & Mulhern, 2002). However, there is reason to suspect that the term persuasion can have negative connotations for some individuals ( Dole & Sinatra, 1999; Murphy, 2001). Therefore, we examined 182 primarily preservice teachers’ views of teaching as persuasion, and related those views to their openness/resistance to new ideas as measured by selected epistemological belief scales and dispositional measures. Consistent with our hypotheses, our results indicated that teacher candidates who believed that knowledge evolves, that beliefs can be revised, and that learning is a process of constructing knowledge were more open to persuasive teaching. Our findings provide support for Murphy’s (2001) view of persuasion and suggest further that the teaching as persuasion metaphor would be more successful embedded in an instructional context designed to broaden teachers’ epistemological worldviews.  相似文献   

Towards an information retrieval language based on a relational view of data     

Ian A. Macleod 《Information processing & management》1977,13(3):167-175

Among the problems associated with modern information retrieval systems is the lack of any systematic approach to the design of query language interfaces. In this paper we attempt to show how a relationally organised data base is well suited to bibliographic data management, and how, given such a relational organisation it is possible to construct an interface which separates the query language from the physical representation of the data base. It is also shown how such a query language organisation may be usefully interfaced to existing retrieval systems. Finally a query language for retrieval applications is proposed.  相似文献

Sexual abuse in young children: its clinical presentation and characteristic patterns     

J Gale  R J Thompson  T Moran  W H Sack 《Child abuse & neglect》1988,12(2):163-170

A retrospective record survey was performed using all child clients aged less than 7 years seen at a community mental health center during the period 1982-1984. The total number of 202 children fell into three groups: sexually abused (n = 37), physically abused (n = 35), and nonabused clinical children (n = 130). These groups were compared in order to learn more about sexual abuse in young children. Family background of both abused groups were similar to each other but differed from the nonabused group in having more factors related to family stress than the nonabused group. Clinical presentations of all the children overlapped a great deal symptomatically; however, the sexually abused children had a statistically significant higher frequency of inappropriate sexual behavior than the other two groups. Several characteristics of the abusive patterns suffered by the two abuse groups differed at or near statistical significance: sexually abused children were more often victimized in single acts by nonrelated child perpetrators than were physically abused children.  相似文献   

The components of the female athlete triad do not identify all physically active females at risk     

Melonie Burrows  Helen Shepherd  Stephen Bird  Kenneth Macleod  Bob Ward 《Journal of sports sciences》2013,31(12):1289-1297

Abstract

The purpose of the present study was to assess the effectiveness of the triad components (amenorrhoea, disordered eating, and osteoporosis) in identifying physically active women at risk of long-term health problems. Eighty-two females (mean age 31.1 years, s = 6.7; body mass 58.4 kg, s = 6.6; stature 1.65 m, s = 0.06) completed training, menstrual, and dietary questionnaires. Bone mineral density and size-adjusted bone mineral density were assessed at the femoral neck and lumbar spine using dual energy X-ray absorptiometry. Seventy-eight percent of participants were eumenorrhoeic, 20% were oligomenorrhoeic, and 2% were amenorrhoeic. Thirty-six percent and 55% reported disordered eating practices in the present and past respectively. Eighty-one percent, 17%, and 2% were classified as normal, osteopaenic, and osteoporotic at the femoral neck respectively; 92% were normal, 7% osteopaenic, and 1% osteoporotic at the lumbar spine. No significant differences in femoral neck size-adjusted bone mineral density were observed between eumenorrhoeic and oligo/amenorrhoeic participants (F _2,80 = 0.119, P = 0.73); eumenorrhoeic participants had significantly greater lumbar spine size-adjusted bone mineral density (F _2,80 = 9.79, P = 0.003). Disordered eating participants had significantly lower femoral neck size-adjusted bone mineral density than those reporting no disordered eating (F _2,80 = 13.816, P = 0.000). Twenty-two percent of participants fulfilled triad criteria, while 55% were “at risk” of long-term health problems. An accumulation of conditions resulted in lower lumbar spine size-adjusted bone mineral density (F _1,80 = 6.074, P = 0.004). The current triad components do not identify all women “at risk” and more appropriate criteria such as exercise-related menstrual alterations, disordered eating, and osteopaenia are suggested.  相似文献   

Estimation of Maximum Oxygen Uptake in Adults from AAHPER Youth Fitness Test Items     

Harold B. Falls  A. H. Ismail  D. F. Macleod 《Research quarterly for exercise and sport》2013,84(2):192-201

Abstract

The validity of estimating maximum oxygen uptake from AAHPER Youth Fitness Test items was determined utilizing 87 adult subjects. Multiple correlations were obtained utilizing the motor fitness items as independent variables. Three dependent variables were investigated for relationship to the independent variables (gross O₂ uptake, O₂ uptake/kg body wt., O₂ uptake/kg lean body wt.). The multiple correlation of the AAHPER items with O₂ uptake/kg body wt. (0.760) was higher than with the other two variables. It was determined by multiple regression techniques that a subset of four of the independent variables could be used to get an estimate of O₂ uptake/kg body wt. with an associated standard error of ± 12 percent of the estimated values. This was compared with the standard errors of more complicated estimation methods.  相似文献
