Accuracy and Precision     

Oliver D. Anderson 《Teaching Statistics》1992,14(3):2-5

Within the framework of a two-hour interactive lecture, we explore the related ideas of accuracy and precision in calculation. The aim is to show that numerical data must be understood as numbers in a context.  相似文献   

Forecasting the value of training     

Dave Basarab 《Performance Improvement》2011,50(3):22-27

The Predictive Evaluation (PE) model is a training and evaluation approach with the element of prediction. PE allows trainers and business leaders to predict the results, value, intention, adoption, and impact of training, allowing them to make smarter, more strategic training and evaluation investments. PE is invaluable for companies that struggle to define the success of training, fight to justify its value, or view training as an expense rather than an investment with predicted return.  相似文献   

Developing policies for inclusive education: a study of the role of local education authorities     

Mel Ainscow  Peter Farrell  Dave Tweddle 《International Journal of Inclusive Education》2013,17(3):211-229

In many parts of the world there is evidence of initiatives aimed at finding ways of creating forms of mainstream schooling that can respond to pupils with disabilities and others seen as having special educational needs (UNESCO 1995). There is also a growing research literature that throws light on how schools and classrooms can be developed in relation to this idea (e.g. Rouse and Florian 1996, Sebba and Sachdev 1997, Thomas et al. 1998, Ainscow 1999, Clark et al. 1999). However, few studies have considered the contributions and roles of local administrative arrangements to such developments, even though there is evidence that these can be highly influential in relation to policy implementation in general (Spillane 1998). Drawing on the evidence of a recent study carried out in England, this paper starts to fill this gap. Specifically, it addresses the question: in what ways do local administrative arrangements bear on attempts to develop more inclusive ways of working in schools? In considering the evidence and arguments presented it is important to recognize that the peculiarities of each national context mean that district level arrangements for the management of education in one country cannot be assumed to be similar to that in other countries. Consequently, transporting conclusions from one situation to another is impossible. Nevertheless, a detailed engagement with the experiences of particular countries can provide a useful basis for reflection on what happens elsewhere. Before considering this specific agenda, however, we summarize certain relevant international trends.  相似文献   

Was grenzt das Kompetenzkonzept von etablierten Kategorien wie Fähigkeit,Fertigkeit oder Intelligenz ab?     

Oliver Wilhelm  Reinhold Nickolaus 《Zeitschrift für Erziehungswissenschaft》2013,16(1):23-26

Following a specification of the concept “competence” as it is applied in the context of the priority program we place recent efforts on competence assessment within established distinctions. Besides Cronbach’s differentiation of typical behavior and maximal effort and Cattell’s demarcation of test and questionnaire data additional discriminations against broader terms such as “ability”, “skill”, “talent” but also “intelligence” are desirable and necessary. The utility of the concept of competence relative to established terms needs to be demonstrated unequivocally in the future.  相似文献   

Effective Strategies for Information Technology in Teacher Education: the use of an evolving permeation model     

Dave Pratt 《Technology, Pedagogy and Education》2013,22(1):53-61

ABSTRACT

This paper examines the debate in recent years about the most effective strategy for establishing the use of information technology in teacher training establishments in the United Kingdom. Evidence is presented to support the notion that efforts should continue to permeate the use of information technology throughout the courses of such establishments. However, the paper suggests that staff development and the degree of permeation of information technology within the culture develop alongside each other. As one of these variables change, it feeds the development of the other; neither is an independent variable though both are influenced by external factors. Recognising this as a relatively slow process, the paper proposes a model of evolutionary permeation.  相似文献   

Explaining Method Effects Associated With Negatively Worded Items in Trait and State Global and Domain-Specific Self-Esteem Scales     

José M. Tomás  Amparo Oliver  Laura Galiana  Patricia Sancho  Marisol Lila 《Structural equation modeling》2013,20(2):299-313

Several investigators have interpreted method effects associated with negatively worded items in a substantive way. This research extends those studies in different ways: (a) it establishes the presence of methods effects in further populations and particular scales, and (b) it examines the possible relations between a method factor associated with negatively worded items and several covariates. Two samples were assessed: 592 high school students from Valencia (Spain), and 285 batterers from the same city. The self-esteem scales used were Rosenberg's Self-Esteem Scale, the State Self-Esteem Scale, and Self-Esteem 17. Anxiety was also assessed with the State-Trait Anxiety Inventory, and gender and educational level were taken into account. The models were conducted using a multiple indicators and multiple causes (MIMIC) model framework. The evidence in this research pointed out that method effects were present across the different measures of self-esteem. Moreover, a significant and negative effect of anxiety on method effects was present across scales and samples, whereas no effects of age or educational level where found.  相似文献   

Autism,Intensive Interaction and the development of non-verbal communication in a teenager diagnosed with PDD-NOS: a case study     

Amandine Mourière  Dave Hewett 《Support for Learning》2021,36(3):400-420

In this paper, the authors report on the importance of using Intensive Interaction for the development of non-verbal communication for people with autism. The complexity of learning non-verbal communication means that it cannot be taught in any sense in a traditional, didactic manner. While a person may have the cognitive abilities to follow instructions and be taught the need to behave a certain way in social situations, which will not allow them to properly assimilate and understand social expectations and how to operate in social contexts. This paper suggests that the use of Intensive Interaction creates frequent opportunities for a person to take part in face-to-face interactions and consequently allow for the gradual development of non-verbal communication.  相似文献   

The Efficacy of Inquiry-Based Instruction in Science: a Comparative Analysis of Six Countries Using PISA 2015     

Oliver  Mary  McConney  Andrew  Woods-McConney  Amanda 《Research in Science Education》2019,51(2):595-616

This study is a comparative analysis of 15-year-old students’ scientific literacy, and its association with the instructional strategies that students experience, across six OECD countries that participated in PISA 2015. Across the six countries, the study investigates the efficacy of inquiry-based instruction in science in contrast with two other instructional approaches to teaching secondary science: adaptive and teacher-directed teaching. The analysis shows that students who reported experiencing high frequencies of inquiry strategies in their classrooms consistently evidenced lower levels of scientific literacy across the six countries. Benchmark analysis also showed, common to all six countries, a strongly positive association between the frequency of teacher-directed and adaptive teaching strategies and students’ scientific literacy. Additionally, the study disaggregates PISA’s composite variable representing inquiry-based instruction and shows that different components of inquiry are differentially associated with students’ scientific literacy. We discuss the implications of these analyses for science teacher educators, science teachers, and educational policy makers. In doing so, we add nuance to our understanding of the efficacy of inquiry-based instruction in science, suggesting that some components, as conceptualised and assessed in PISA, seem to suggest greater attention and use, and others more moderated use.

Public health practitioners' information access and use patterns in the Maryland (USA) public health departments of Anne Arundel and Wicomico Counties     

Twose C  Swartz P  Bunker E  Roderer NK  Oliver KB 《Health information and libraries journal》2008,25(1):13-22

PURPOSE: To increase understanding of the information needs and use of public health practitioners. SETTING: From June 2005 to May 2006, the library offered a course in public health information resources to eighteen practitioners in two counties, access to the library's licensed electronic resources through a tailored web portal, and consulting services. EVALUATION METHOD: We combined usage statistics from the web portal, self-report and observational data collected during training and shadowing of participants. CONCLUSIONS: The data from this project indicate that usage of licensed information resources and services is infrequent but broad ranging. A few users register at the high end of the usage range, but one use of one high quality article can have a significant impact on policy decisions. Time and competing responsibilities often constrain the retrieval and use of resources for evidence-based decision making and an informationist or power-user model may be more appropriate than training all practitioners to integrate searching into their workflow. This study indicates (i) that evidence-based public health practice requires seamless and broadly based information access; and (ii) that the currently existing patchwork does not support the level of use or take into account the time constraints of information needs for public health practice.  相似文献   

Standardization of search methods for guideline development: an international survey of evidence-based guideline development groups     

Deurenberg R  Vlayen J  Guillo S  Oliver TK  Fervers B  Burgers J;SEARCH Group 《Health information and libraries journal》2008,25(1):23-30

BACKGROUND: Effective literature searching is particularly important for clinical practice guideline development. Sophisticated searching and filtering mechanisms are needed to help ensure that all relevant research is reviewed. PURPOSE: To assess the methods used for the selection of evidence for guideline development by evidence-based guideline development organizations. METHODS: A semistructured questionnaire assessing the databases, search filters and evaluation methods used for literature retrieval was distributed to eight major organizations involved in evidence-based guideline development. RESULTS: All of the organizations used search filters as part of guideline development. The medline database was the primary source accessed for literature retrieval. The OVID or SilverPlatter interfaces were used in preference to the freely accessed PubMed interface. The Cochrane Library, embase, cinahl and psycinfo databases were also frequently used by the organizations. All organizations reported the intention to improve and validate their filters for finding literature specifically relevant for guidelines. DISCUSSION: In the first international survey of its kind, eight major guideline development organizations indicated a strong interest in identifying, improving and standardizing search filters to improve guideline development. It is to be hoped that this will result in the standardization of, and open access to, search filters, an improvement in literature searching outcomes and greater collaboration among guideline development organizations.  相似文献
