This paper discusses the use of systems development research methods in the context of ongoing research that is formulating
a specification for a metadata schema registry. The paper extrapolates from this discussion how such methods can be utilized
in archival systems research and how such an approach differs from commercial systems engineering. In particular, the paper
suggests that adopting a user-centred prototyping approach in a research context allows for exploration of the interplay between
theory and practice, advancing the practice, while also offering new insights into theoretical concepts. It argues that these
research methods are of increasing interest to the archival profession in order to conceptualise and realise the tools necessary
to support recordkeeping and archival processes in digital environments. 相似文献

EUROPEAN PUBLIC PERCEPTIONS OF SCIENCE 总被引:2,自引:0,他引:2
Bauer Martin; Durant John; Evans Geoffrey 《Int. Journal of Public Opinion Research》1994,6(2):163-186
In this paper we explore the relationships between public interestin, knowledge of, and attitudes towards science and technologyand the level of industrialization in 12 countries of the EuropeanCommunity. Using the 1989 Eurobarometer survey no 31 (N=11,678),we constructed four scales measuring interest, knowledge, generalattitudes to science, and support for EC funded science foreach of the 12 EC countries. We found that overall factual scientificknowledge correlates moderately positively with interest andattitudes to science. For example the Netherlands and GreatBritain have relatively high levels of knowledge, interest,and support for science in general. Spain and Greece have relativelylow levels of knowledge, interest, and support for science ingeneral. However, the simple correlation hides more complexrelationships. First, the variance within and across countriesof knowledge, attitudes and interest increases with nationallevels of knowledge. This indicates greater degrees of polarizationof both support and interest. Second, the data indicates a post-industrialismeffect: knowledge, interest in, and attitudes to science showa curvilinear relationship with levels of industrialization.The decline of interest in science and the less positive attitudesin highly developed countries requires further exploration.Third, we found, that the consistency of the knowledge and theattitude measures declines as the national level of knowledgeincreases. We suggest that this reflects a knowledge-ignoranceparadox and knowledge specialization among informed populations.Support for EC level science follows a different pattern. Wefound that France, Italy, and Spain show high levels of supportfor EC level science. This is not the case in Great Britainand Germany. The pattern suggests that attitudes towards ECscience are formed on the basis of national level scientificstrength: if the national science base is strong, EC scienceinitiatives find less support and vice versa. These findingsrepresent a first step towards a comparative assessment of publicunderstanding of science in EC countries. 相似文献

The classical criteria for controllability and observability are given a tensorial formulation which is then extended into Boolean form directly related to a digraph interpretation of system structure. This is examined in detail with particular reference to group theoretic aspects, invariant properties under transformation, the term rank test and the existence of zero eigenvalues.Within this framework the structural design concepts of potential controllability and observability are presented in generalised terms. 相似文献

The graph theoretic aspects of controllability and observability are examined and related to the tensorial formulation of Part I of the paper. Particular emphasis is given to the significance of the system digraph decomposition and the relevance of this to certain system algebraic properties of interest in control theory. 相似文献

Using data on the ‘career’ paths of one thousand ‘leading scientists’ from 1450 to 1900, what is conventionally called the
‘rise of modern science’ is mapped as a changing geography of scientific practice in urban networks. Four distinctive networks
of scientific practice are identified. A primate network centred on Padua and central and northern Italy in the sixteenth
century expands across the Alps to become a polycentric network in the seventeenth century, which in turn dissipates into
a weak polycentric network in the eighteenth century. The nineteenth century marks a huge change of scale as a primate network
centred on Berlin and dominated by German-speaking universities. These geographies are interpreted as core-producing processes
in Wallerstein’s modern world-system; the rise of modern scientific practice is central to the development of structures of
knowledge that relate to, but do not mirror, material changes in the system.

ABSTRACTOnline learning has become a ubiquitous part of the educational landscape and how teachers are supported in developing approaches to teaching online is a fundamental aspect of the students’ learning experience. Based on the implementation of a professional development course on becoming an online teacher offered in a blended learning mode at one university in Hong Kong, this article proposes that offering this type of professional development in a blended mode is very effective in facilitating enhanced usage of the university’s learning management system. In a blended mode, teachers are actively engaged with blended learning and were found to make more extensive use of features/tools in Blackboard after they attended the professional development course. Results support that offering professional development in a blended mode provides teachers with an authentic student perspective, at the same time as they take guided steps in the teacher’s role in blended learning. 相似文献

This article explores the key characteristics of postsecondary education programs that help youth and young adults with disabilities persist and remain in college. Student support factors include services that develop stronger self-determination skills, teach and support young adults' self-management skills, expose students to assistive technology, and promote career development by providing internships or other career-related experiences. In conjunction with student support services there are two professional development emphases for instructional faculty that contribute to the institutional support needed by college students with disabilities. Students benefit when faculty have an increased awareness and knowledge of the characteristics and needs of students with disabilities and when faculty incorporate concepts of universal design into their instruction and curriculum. 相似文献

AbstractSince 2003, the Programme for International Student Assessment (PISA) has included students with special educational needs (SEN), identified as those with functional disabilities, those with cognitive/behavioural/emotional disabilities and those with limited test language proficiency. While the number of countries and included students has increased with each test administration, the percentage of students with SEN remains extremely low. The inclusion of these students is not an intentional PISA design parameter but rather a response to the interaction between the need to maintain strict sampling criteria and country-level educational mandates to include SEN students in standardised testing. Based on the analysis of student participation and performance across four cycles of PISA (2003–2012), this paper examines the challenges that exist in current PISA procedures related to: student sampling, eligibility and identification; assessment methodology; and reporting results. PISA practices, their limitations for scientific inferences and recommendations for design improvements are given. 相似文献

The relationship between cognitive style and trainee teacher conceptions of differentiation was studied to develop appropriate
scaffolding of their learning. 149 trainee teachers enrolled on 1 year postgraduate initial teacher education (ITE) programmes
at two UK universities completed the Cognitive Style Index (Allinson and Hayes, Journal of Management Studies, 33(1):119–135,
1996; Hodgkinson and Sadler-Smith, Journal of Occupational and Organisational Psychology, 76(2):243–268, 2003) and a questionnaire exploring their understanding of differentiation, conceptions of learning and learning preferences.
A stratified sample of these trainees was also interviewed to assess their understanding and prior knowledge of differentiation
and learning styles and how they would plan for these in the classroom. Responses were coded using content analysis procedures.
Cognitive style was found to impact on trainees’ conceptions of differentiation; for example, trainees demonstrating higher
levels of analysis and intuition had a more developed understanding of differentiation than other cognitive styles. In relation
to the findings, the use of a constructivist pedagogical tool: a Personal Learning Styles Pedagogy (Evans and Waring, Zhang
& Sternberg (Eds.), Perspectives on the nature of intellectual styles, 2009) is presented to inform the reconceptualisation of ITE programmes. In so doing, the use of this tool addresses key issues
raised in recent international policy debates concerning the necessary development of ITE for twenty-first century learner
needs. 相似文献
