Feedback mechanisms in learning virtual community settings     

Luigi Colazzo Alessio Comai Filippo Davi Andrea Molinari Nicola Villa 《美中教育评论》2010,(1):76-84

This paper introduces a set of services for the creation of on-line surveys, questionnaires, exams and self-assessment tests within a virtual community system used in e-learning settings. The system, called ＂Online Communities＂, is a dynamic web application used as platform for blended learning activities by the Faculty of Economics of the University of Trento. The functionalities added to the platform are contextualized into virtual communities, where activities take place. This allows us to create, submit and analyze questionnaires within and/or outside the boundaries of a community. Furthermore, the system allows to manage libraries of queries organized by the teacher/administrator of the community according to topics and levels of difficulty, in order to produce tests and generate self-assessment sessions on behalf of students. The addition of a questionnaire/ poll/self-assessment tool to a virtual community system can add a lot of interesting features, mainly using the inheritance mechanism implemented among different hierarchically-connected communities. This paper will present these functionalities and highlight one of these services, precisely the one dedicated to self-assessment. In the system, self-assessment tests have indeed a double nature： （1） They are useful to students for checking their own level of preparation; and （2） They are useful to lecturers as an indicator of the level of preparation reached by the students. In order to encourage the use of the system within the whole educational process, and not to limit the real use of the service to the period of the final exams only, the possibility has been foreseen for each participant to share his/her own test results, comparing them with the other members of the community, and even offering real ＂challenges＂, thus transforming passive and ＂solitary＂ learning into something much more stimulating and ＂social＂.  相似文献   

Becoming numerate with information and communications technologies in the twenty‐first century     

Nicola Yelland  Anna Kilderry 《International Journal of Early Years Education》2010,18(2):91-106

This article draws on data from a three‐year Australian Research Council‐funded study that examined the ways in which young children become numerate in the twenty‐first century. We were interested in the authentic problem‐solving contexts that we believe are required to create meaningful learning. This being so, our basic tenet was that such experiences should involve the use of information and communications technologies (ICT) where relevant, but not in tokenistic ways. This article highlights learning conditions in which young children can become numerate in contemporary times. We consider ‘academic’ or ‘school‐based’ mathematical tasks in the context of a Mathematical Tasks Continuum. This continuum was conceptualised to enable focused and detailed thinking about the scope and range of mathematical tasks that young children are able to engage within contemporary school contexts. The data from this study show that most of the tasks the children experienced in early years mathematics classes were unidimensional in their make up. That is, they focus on the acquisition of specific skills and then they are practiced in disembedded contexts. We suggest that the framework created in the form of the Mathematical Tasks Continuum can facilitate teachers’ thinking about the possible ways in which they could extend children’s academic work in primary school mathematics, so that the process of becoming numerate becomes more easily related to authentic activities that they are likely to experience in everyday life.  相似文献   

Searching the Web to learn about a controversial topic: are students epistemically active?   总被引：1，自引：0，他引：1  

Lucia Mason  Angela Boldrin  Nicola Ariasi 《Instructional Science》2010,38(6):607-633

Students are making an increased use of the Web as a source for solving information problems for academic assignments. To extend current research about search behavior during navigation on the Web, this study examined whether students are able to spontaneously reflect, from an epistemic perspective, on the information accessed, and whether their epistemic metacognition is related to individual characteristics, such as prior knowledge of the topic and the need for cognition. In addition, we investigated whether Internet-based learning is influenced by the activation of spontaneous epistemic metacognition in the search context. Forty-six psychology and engineering university students were asked to research information about a controversial subject in order to write an essay. They were also asked to think aloud during their research. Both qualitative and quantitative analyses were performed. As revealed by their spontaneous reflections, all participants were epistemically active, although to different extents and levels. As expected, there was evidence that students activated beliefs about the four epistemic dimensions identified in the literature, especially about the credibility of an electronic source and the criteria for justification of knowledge. Prior knowledge was not related to activation of epistemic beliefs in the search context, while the need for cognition significantly associated with aspects of source and its content evaluation. Two patterns of epistemic metacognition were identified and they significantly influenced Internet-based learning. Students who spontaneously generated more sophisticated reflections about the sources as well as the information provided, outperformed students who were active only at the first epistemic level. Educational implications are drawn.  相似文献   

Evaluation of an intervention to help students avoid unintentional plagiarism by improving their authorial identity   总被引：1，自引：0，他引：1

Students with poorly developed authorial identity may be at risk of unintentional plagiarism. An instructional intervention designed specifically to improve authorial identity was delivered to 364 psychology students at three post‐1992 universities in London, UK, and evaluated with before‐and‐after measures of beliefs and attitudes about academic authorship, using the Student Authorship Questionnaire. Changes in questionnaire scores showed that the intervention led to significantly increased confidence in writing, understanding of authorship, knowledge to avoid plagiarism, and top‐down approaches to writing, and significantly decreased bottom‐up and pragmatic approaches to writing. For understanding of authorship, knowledge to avoid plagiarism and pragmatic approaches to writing, significant intervention by year of study interaction effects showed that the greatest improvements were among year one undergraduates. Direct evaluative feedback showed that 86% of students believed the intervention helped them avoid plagiarism and 66% believed it helped them write better assignments. Post‐intervention focus groups revealed changed student understandings about authorial identity and academic writing. The results show that interventions can help students avoid unintentional plagiarism by adopting more authorial roles in their academic writing. Further research could explore other influences on authorial identity, and examine the impact of authorial identity interventions on other outcome indicators.  相似文献   

The effects of post-compulsory education and training systems on literacy and numeracy skills: A comparative analysis using PISA 2000 and the 2011 survey of adult skills     

Nicola Pensiero  Andy Green 《European Journal of Education》2018,53(2):238-253

This article analyses the contribution of post-compulsory education and training systems to the development of literacy and numeracy skills across OECD countries. While there is extensive cross-country comparative research on the effects of primary and lower secondary education systems on aggregate skills levels, there has been little comparative analysis of system effects after the end of lower secondary education. This article uses a quasi-cohort analysis of the tested literacy and numeracy skills of 15-year-olds in PISA 2000 and 27-year-olds in the 2011 OECD Survey of Adult Skills (SAS) to estimate the gains in different countries in mean levels of competence in literacy and numeracy. We found that Nordic countries (Norway and Sweden) with comprehensive upper secondary education and training systems and German-speaking countries (Austria and Germany) with dual systems of apprenticeship were particular effective, whilst countries with mixed systems (England, Ireland, Northern Ireland and Spain) showed a relative decline in both literacy and numeracy. The education system characteristics that account for these differences are (a) the inclusiveness – as proxied by high rates of participation at 17/18 and low social gradients of level 3 completion; (b) the esteem of vocational programmes; and (c) curriculum standardisation with regard to the study of maths and the national language.  相似文献   

Learning about assessment: the impact of two courses for higher education staff     

Nicola Reimann 《International Journal for Academic Development》2018,23(2):86-97

This interview-based study investigated the impact of two academic development courses about assessment. Participants learnt concepts and terminology that enabled them to better understand and communicate about assessment. The courses also stimulated critical thinking about assessment practices and conceptual change, with ‘assessment for learning’ emerging as significant with the qualities of a threshold concept. Certain learning activities stood out as transformational as they supported the examination of assessment from different perspectives and the integration of implicit with explicit knowledge, but only if participants had sufficient workplace experience that they could link to the formal knowledge taught in the courses.  相似文献   

An investigation into breast support and sports bra use in female runners of the 2012 London Marathon     

Nicola Brown  Jennifer White  Amanda Brasher  Joanna Scurr 《Journal of sports sciences》2013,31(9):801-809

Abstract

Although it is acknowledged that appropriate breast support during exercise is important, no published literature has assessed breast support usage in a cohort of female marathon runners. This study aimed to identify sport bra use and perceived importance of sports bra use in female marathon runners. Bra satisfaction, incidence of bra related issues and factors that influence the appropriateness of sports bras were also investigated. A 4-part, 30-question survey was administered to 1397 female runners at the 2012 London marathon registration and via an online survey. In total 1285 surveys were completed. Sports bra use and its perceived importance was high, however was lower in moderate compared to vigorous activity, and lower in participants with smaller breasts. Seventy-five per cent of participants reported bra fit issues. The most common issues were chaffing and shoulder straps digging in, with a higher incidence of issues reported by participants with larger breasts. Use of professional bra fitting was low, and perceived knowledge of breast health was poor. Engagement with sports bra use is high although sports bra design could be improved to alleviate bra fit issues experienced by female runners. Educational initiatives are needed to ensure females are informed regarding the importance of breast support and appropriate bra fit during activity.  相似文献   

The effect of boot stiffness on field and laboratory flexural behavior of alpine ski boots     

Nicola Petrone  Giuseppe Marcolin  Fausto A. Panizzolo 《Sports Engineering》2013,16(4):265-280

The aim of this work was to study the effect of boot stiffness on the field and laboratory flexural behavior of alpine ski boots. Ski boots have a direct influence on performance, safety, and comfort of alpine skiers. Despite their technological evolution during a number of years, the parameters used in the evaluation of boot stiffness are not yet standardized and still require a shared engineering approach to achieve common quantitative definitions to be used either in boot classification or in boot selection for the different users. This work reports the boot flexion angles between shell and cuff and between cuff and tibia, collected during slalom tests on three boots with different nominal Flex Index. The laboratory data collected on the same boots under conventional cyclic bending tests are reported and compared with the field data for the development of a new test method more representative of the field behavior. As a result, clear definitions of Flex Index and of boot stiffness are introduced: boot stiffness had a clear effect on both the field and the laboratory flexural behavior of boots.  相似文献   

Characteristics of the start in women's World Cup skeleton     

Nicola Bullock  David T. Martin  Angus Ross  Doug Rosemond  Terry Holland  Frank E. Marino 《Sports biomechanics / International Society of Biomechanics in Sports》2013,12(3):351-360

This study characterizes key elements of the start in elite female World Cup skeleton athletes. The top 20 female competitors in three World Cup races were videotaped within a calibrated space to allow the following components of the start to be quantified: (1) acceleration (velocity at 15-m mark, time to 15-m mark), (2) capacity (time to load, total number of steps to load), and (3) load (velocity at 45-m mark). A correlation analysis was used to establish the relationship between the variables of interest and overall start time (15- to 65-m mark). Velocity at the 15-m mark accounted for 86% of the variance in overall start time at St. Moritz and 85% at Sigulda. A stepwise regression analysis revealed that approximately 89% of the variation in start time could be explained by velocity at the 15-m mark, time to load, and velocity at the 45-m mark. Of the variables analysed in this study, rapid acceleration to attain a high velocity at the 15-m mark was the most important component of a fast overall start time. The importance of the time to load and velocity at the 45-m mark vary according to the different track characteristics.  相似文献
