Learning from Failure: A Cost-Benefit Analysis Study Which Resulted in Unfavorable Financial Outcomes     

Ronald L. Jacobs  Maria T. Hruby-Moore 《Performance Improvement Quarterly》1998,11(2):93-100

This article describes a cost-benefit analysis study which resulted in unfavorable financial outcomes and discusses how this result became a learning opportunity for human performance development (HRD) professionals in the organization. Demonstrating the contributions of human performance development/performance improvement (HRD/PI) programs through cost-benefit analysis is a continuing need in organizations. However, most cost-benefit analysis case studies have reported favorable financial results. While these results may help raise the perceived status of the field, in fact, reporting unfavorable results may provide a richer professional learning opportunity than otherwise might be available.  相似文献   

Third and fourth graders' conceptions of repeated trials and best representatives in science experiments     

Maria Varelas 《科学教学研究杂志》1997,34(9):853-872

This study involved 24 third- and fourth-grade students in a suburban school in the Chicago area. These children had been learning science through a reform-based, integrated science and mathematics curriculum for about 2 years. In this study I explore how these children made sense of a scientific procedure that had been introduced to them and they had used before in their own experimental inquiries: performing repeated trials and determining the best representative of the measurements of a continuous dependent variable. Specifically, I explore how children made sense of the variability in the results of repeated trials, how their ideas of repeated trials and best representatives are related to their understandings of the sources of the variability, and how they thought about what would be the best representative of their measurements. The data and analysis reveal the complexity of the understandings involved in this apparently simple procedure, as children attempted to appropriate for themselves the procedure that had been introduced to them. The results support the idea that many of the children had not conceptualized the procedure of repeating trials and finding the best representative of the results in the way adult practitioners do. They also point to the value of introducing children to such experimental procedures. © 1997 John Wiley & Sons, Inc. J Res Sci Teach 34: 853–872, 1997.  相似文献   

Music search engines: Specifications and challenges     

Alexandros Nanopoulos  Dimitrios Rafailidis  Maria M. Ruxanda  Yannis Manolopoulos 《Information processing & management》2009

Nowadays we have a proliferation of music data available over the Web. One of the imperative challenges is how to search these vast, global-scale musical resources to find preferred music. Recent research has envisaged the notion of music search engines (MSEs) that allow for searching preferred music over the Web. In this paper, we examine the growing research topic of MSEs, and provide potential specifications to follow and challenges to face.  相似文献   

The Paradox of Being a Woman Teacher     

Maria Tamboukou 《Gender and education》2000,12(4):463-478

In this article, the author follows genealogical lines of analysis in an attempt to map the different discourses and practices that interweave women's position in education today. Education is theorised as a nexus of created paradoxical spaces, where the female self has attempted to surpass closed boundaries and to question the dichotomy of the feminised private and/or the masculine public. The author also considers the importance of time restrictions upon women's lives and pays attention to the multifarious ways these lives are highly structured by specific space/time regulations. The genealogical mapthat is drawn depicts various positions, where the female self has created parodic unities and temporary coalitions. Finally, in tracing exit points that education has offered women, the author considers some of the implications of feminist theories for the subversion of the various dilemmas and dichotomies the female subject has lived through.  相似文献   

The virtual laboratory concept applied to strain measurements     

Lluís Gil  Elena Blanco  Josep Maria Aulí 《European Journal of Engineering Education》2000,25(3):243-251

In recent years the methodology of engineering education has been changing and many projects deal with improving the educational software. This paper reports on the virtual laboratory, a virtual environment applied to experimental analysis. The goals of the virtual laboratory are to introduce the laboratory environment to the student entering this world, so different from the typical theoretical lectures, for the first time, and to overcome the above-mentioned drawbacks. It should be mentioned that the virtual laboratory is not meant to replace highly enriching, practical experience, but rather is meant to train the individual, in order to improve his/her performance in later actual practice. The virtual laboratory experience starts with the study of strain measurements, an engineering technique widely used to measure deformations, strains, mechanical properties of materials and other variables which are used to analyse many problems.The strain measurement virtual laboratory is meant to offer the possibility of simulating experiences, undergone in a real laboratory, through the Internet. The student is expected to familiarize him/herself with the techniques, procedures, devices and theories in the laboratory environment.  相似文献

Intermingling and bumpiness: Exploring meaning making in the discourse of a science classroom     

Maria Varelas  Edgar Pineda 《Research in Science Education》1999,29(1):25-49

In this study we capture and analyse in qualitative terms the conversational rhythm—the ebb and the flow of meaning making—in a Year 5 class in order to understand when and how teacher and students succeed in developing shared understandings, and when and how they encounter difficulties. We use the two contrasting concepts of intermingling and bumpiness to catch the phenomenological aspect of time in the science class, which is constituted by the voices of the teacher and the students as they come together to construct disciplinary knowledge. It is a collaborative action research that sheds light on the struggles and possibilities that arise in a science class as a teacher enacts a socio-cultural perspective and engages his students in collecting and analysing experimental data and reasoning through a particular model.  相似文献

Technology transfer in schools: from research to innovation     

Rosa Maria Bottino  Paola Forcheri  & Maria Teresa Molfino 《British journal of educational technology : journal of the Council for Educational Technology》1998,29(2):163-172

Technology transfer should be a central objective of research into educational information technology, as it is generally acknowledged that the quality of this process is a critical factor in effectively bringing about innovation. The central focus of this paper is on this problem. In particular, we discuss the peculiarity of information technology transfer in schools as opposed to the transfer of technology in companies; we indicate some central problems of this transfer and discuss a typology of approaches to the transfer of educational information technology from research to school.  相似文献   

Goal orientations and moral identity as predictors of prosocial and antisocial functioning in male association football players   总被引：1，自引：0，他引：1  

Sage L  Kavussanu M  Duda J 《Journal of sports sciences》2006,24(5):455-466

The purpose of this study was to examine the effects of task and ego goal orientation and moral identity on prosocial and antisocial judgement and behaviour in football. The interaction between task and ego orientation in predicting these variables was also examined. Participants were 210 adult male footballers (age 25 +/- 6 years) competing at recreational (n = 133) and semi-professional (n = 77) levels. They completed questionnaires measuring task and ego goal orientation, the importance of moral identity, prosocial and antisocial judgement, frequency of prosocial and antisocial behaviours in football, and social desirability. Regression analysis revealed no main effects for goal orientations and moral identity on prosocial judgement and behaviour. However, a significant interaction effect between task and ego orientation emerged in relation to prosocial judgement. Specifically, task orientation positively predicted prosocial judgement only at low levels of ego orientation. Ego orientation emerged as a positive predictor of antisocial judgement and behaviour, whereas moral identity negatively predicted these variables. The differentiation between prosocial and antisocial aspects of morality was supported. It was concluded that examining moral identity and interactions between task and ego orientation adds to our understanding of the influence of these variables on prosocial and antisocial functioning in sport.  相似文献
