How environmental knowledge measures up at a Big Ten university   总被引：1，自引：1，他引：0  

Michael D. Kaplowitz  Ralph Levine 《Environmental Education Research》2005,11(2):143-160

The reported research examines the level of environmental knowledge of Michigan State University students relative to the results of a biannual national study of the environmental knowledge of the general population of the United States. While the university students were found to possess higher levels of environmental knowledge than the general public, the students' overall environmental knowledge, on average, was deficient with only 66% of them receiving a passing grade. The findings suggest a positive correlation between academic level, field of study and environmental knowledge.  相似文献   

Cross‐border Higher Education Collaboration in Europe: lessons for the ‘two Irelands’?     

ROBERT D. OSBORNE 《European Journal of Education》2006,41(1):113-129

This article examines three examples of cross-border higher education collaboration in Europe in order to throw light on one European region where such collaboration is only in its early stages of development. The main region examined is the Öresund region covering the Skåne area of Southern Sweden centred on Malmo and the Zealand region of Denmark which incorporates the Copenhagen region. Additionally, and more briefly, the Upper Rhine collaboration of the EUCOR universities and the ALMA collaboration (Netherlands, Germany and Belgium) are considered. Lessons from these examples are then used to assist in the assessment of existing collaboration between higher education institutions in the Republic of Ireland and Northern Ireland and the possibilities for further collaboration.  相似文献   

Predicting ground reaction forces in running using micro-sensors and neural networks     

D. C. Billing  C. R. Nagarajah  J. P. Hayes  J. Baker 《Sports Engineering》2006,9(1):15-27

Measurement of ground reaction force (GRF) in running provides a direct indication of the loads to which the body is subjected at each foot-ground contact, and can provide an objective explanation for performance outcomes. Traditionally, the collection of three orthogonal component GRF data in running requires an athlete to complete a series of return loops along a laboratory based runway, within which a force platform is embedded, in order to collect data from a discrete footfall. The major disadvantages associated with this GRF data collection methodology include the inability to assess multiple consecutive foot contacts and the fact that measurements are typically confined to the laboratory. The objective of this research was to investigate the potential for wearable instrumentation to be employed, in conjunction with artificial neural network (ANN) and multiple linear regression (MLR) models, for the estimation of GRF in middle distance running. A modular wearable data acquisition system was developed to acquire in-shoe force (ISF) data. Matched data sets from wearable instrumentation (source data) and force plate (target data) records were collected from elite middle-distance runners under controlled laboratory conditions for the purposes of ANN and MLR model development (MD) and model validation (MV). In terms of statistical measures of prediction accuracy the MLR model was found to provide a superior level of accuracy for the prediction of the vertical and medio-lateral components of GRF and alternatively, the ANN model provided the most accurate predictions of the anterior-posterior component of GRF. The prediction accuracy of each component of GRF was found to be governed by the inherent signal variability, in which case the vertical and anterior-posterior components were more reliable and subsequently predicted significantly more accurately than the medio-lateral component. The emerging capability for obtaining continuous GRF records from wearable instrumentation has the potential to permit unprecedented quantification of training stress and competition demands in running.  相似文献   

Contrasting the Effectiveness of Fluency Interventions for Students with or At Risk for Learning Disabilities: A Multilevel Random Coefficient Modeling Meta‐Analysis     

Paul L. Morgan  Georgios D. Sideridis 《Learning disabilities research & practice》2006,21(4):191-210

This study had two purposes. First, we sought to compare the overall effectiveness of different types of fluency interventions for students with learning disabilities (LD). Second, we attempted to identify how individual‐ and class‐level characteristics moderated each intervention's effectiveness. We used multilevel random coefficient modeling to analyze results from 30 single‐subject studies involving 107 students with or at risk for LD. Doing so allowed us to assess the intervention's impact in terms of both intercept‐ (i.e., mean difference between study phases) and slope‐level (i.e., rate of growth) changes. Results indicated that two motivation‐focused interventions were significantly more effective than other types of interventions across gender, age, and placement. The least effective intervention was word recognition training; this finding was consistent across all levels of analyzed variables.  相似文献   

An Approach to Teaching Electrical Energy     

R. BELMANS  D. VAN DOMMELEN 《European Journal of Engineering Education》1996,21(1):65-73

The paper discusses the implementation of a new teaching programme for electrical power engineering graduates. The balance between the different parts of the curriculum (non-technical, technical non-electric, electric non-power and real electrical power) is proposed and explained given the specific context. The logical information flow throughout the education process and the links between the course topics are explained.  相似文献   

Rare-earth magnets     

J. M. D. Coey 《Endeavour》1995,19(4)

Magnetism has been known as a natural phenomenon, for over two thousand years and the art of magnetizing steel was mastered half that time ago. However, it is only during this century that really substantial improvements have been made in the energy product of magnets. This article reviews the development of permanent magnets, with special reference to powerful modern alloys containing the rare earths neodymium and samarium.  相似文献

The effect of illustrations in arithmetic problem-solving: Effects of increased cognitive load     

Inez E. Berends  Ernest C.D.M. van Lieshout 《Learning and Instruction》2009,19(4):345-353

Arithmetic word problems are often presented accompanied by illustrations. The present study examined how different types of illustrations influence the speed and accuracy of performance of both good (n = 67) and poor arithmeticians (n = 63). Twenty-four arithmetic word problems were presented with four types of illustrations with increasing information value. The results show that illustrations can have a detrimental effect on performance on arithmetic word problems, produced by irrelevant, redundant or interacting sources of information. Principles from cognitive load theory are used to explain the results, in particular in relation to (poor) working memory ability.  相似文献
