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   

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   

Effects of antisocial behaviour on opponent's anger,attention, and performance     

Christopher Ring  Maria Kavussanu  Ali Al-Yaaribi  Gershon Tenenbaum  Nicholas Stanger 《Journal of sports sciences》2019,37(8):871-877

Sledging, which is verbal antisocial behaviour in sport, aims to impair an opponent’s performance. Previously, variations in performance have been attributed to changes in emotion and cognition. To improve our understanding of sledging, the current experiment examined the effects of verbal antisocial behaviour on anger, attention and performance. Participants performed a competitive basketball free-throw shooting task under insult (verbal behaviour designed to offend and upset the performer), distraction (verbal behaviour designed to draw attention away from the task), or control (neutral verbal behaviour) conditions. Performance was assessed by the number of successful baskets and a points-based scoring system, while anger and attention were measured post-task. The insult condition provoked more anger than the control and distraction conditions, whereas the insult and distraction conditions increased distraction and reduced self-focus compared to the control condition. Although verbal antisocial behaviour had no overall direct effect on performance, mediation analysis showed that anger indirectly impaired performance via distraction. Implications for the antisocial behaviour-performance relationship are discussed.  相似文献

The interpersonal dimension of teacher education: Comparing distance education with two other programs in Sri Lanka   总被引：1，自引：0，他引：1  

Maria Teresa Tatto  N. G. Kularatna 《International Journal of Educational Research》1993,19(8)

This chapter examines a distance education program to train primary schoolteachers in Sri Lanka and looks for evidence of its success. Quasi-longitudinal data on (a) teacher perceptions of the program; (b) teacher knowledge, skill, and attitudes; (c) teacher classroom performance; and (d) pupil achievement are used to compare distance education with two other teacher education programs in Sri Lanka — an institutional inservice program and a preservice approach. More specifically, the interpersonal aspects of this distance education program are examined as a possible explanation of the program's effectiveness when compared with other distance education as well as conventional approaches to educating teachers.  相似文献   

Reliability of a Cryoscopic Micro-Osmometer Using 15-µL Plasma Samples to Measure Hydration Status in Varied Environmental Conditions     

Aaron T. Scanlan  Gina L. Richter-Stretton  Maria C. Madueno  Nattai R. Borges  Andrew S. Fenning 《Measurement in physical education and exercise science》2017,21(1):34-39

Measurement of plasma osmolality (P_osm) remains popular for assessing hydration status in exercise science. However, a controlled reliability assessment of micro-osmometry using small sample volumes to measure P_osm remains to be performed. This study aimed to examine the reliability of a cryoscopic micro-osmometer requiring 15-μL samples across varied environmental conditions. Thirteen young adults (26.4 ± 5.7 years) completed a 20-min steady-state cycling protocol on separate occasions in cool/dry conditions and hot/humid conditions. P_osm was assessed using fingertip capillary samples taken in duplication prior to and following 20-min acclimatization and recovery periods around the cycling bout. Absolute (typical error of measurement = .62–.83 mOsmol·kg^–1; coefficient of variation = .9% to 1.3%) and relative (intraclass correlation coefficient = .60–.85) reliability of this approach were supported. These findings suggest micro-osmometry requiring small plasma samples (15 μL) can be reliably used by practitioners to assess longitudinal changes and cross-sectional hydration status in varied environmental conditions.  相似文献   

Knowledge,nutrition and coaching pedagogy: a perspective from female Brazilian Olympic gymnasts     

Carly Stewart  Laurita Marconi Schiavon  Maria Luisa Bellotto 《Sport, Education and Society》2017,22(4):511-527

It is acknowledged that knowledge and knowledge bases are an important part of coach and athlete learning and that the coach – athlete relationship is crucial to knowledge created, shared and used. This said knowledge about nutrition as constructed by elite gymnasts would seem particularly important in a culture long associated with weight control practices and disordered eating. This paper provides an insight into the ways that 10 Brazilian Olympic gymnasts construct ideas pertaining to nutritional knowledge across generational periods (between 1980 and 2004) where significant organisational change in Women’s Artistic Gymnastics in Brazil occurred and included the introduction of dieticians. Drawing upon different knowledge types and paying attention to the coaching context, the life histories of 10 Olympic gymnasts were used to open a window on knowledge construction pertaining to nutrition by three generations of gymnasts. The findings draw attention to two main illustrative themes. Firstly, coaches’ personal knowledge, whilst perceived as incomplete by gymnasts, reinforced a narrative of weight loss for gymnasts regardless of generation. Secondly, the younger generations of gymnasts perceived that the introduction of dieticians into structured provision enabled them to use better structured knowledge, and with it a sense of increased autonomy and corporeal learning via the construction of tacit embodied knowledge leading to healthier practices. Reflections are given to the role of the coach, dieticians and pedagogical actions, and the continued reshaping of knowledge in elite gymnastics.  相似文献
