This paper reports on problems and conflicts encountered when using decision support systems (DSS) in political contexts. Based on a literature study and two case studies we describe problems encountered in relation not only to the DSS itself, but also to the political decision process. The case studies have been carried out in two cities in Sweden that at different times but in similar situations have used DSS in order to reach a decision in complicated and contested matters. In both cases we have previously found that the method and IT tool used for decision analysis were appreciated by most participants, but the inherent rationality of the DSS was in conflict with how participants usually make decisions as well as with the political process. The assumption was that a strict and open method would make grounds for clear decisions, but the results of the decision process were none of the cases implemented. In one case the result of the decision analysis was that no clear decision was made. In the other case the lowest ranked alternative was implemented. Furthermore, in neither city the method was ever used again. We therefore ask: What are the challenges and limitations to using DSS in political contexts? Our study shows that challenges relate to selecting and using criteria; eliciting weights for criteria (high level of subjectivity); understanding all the amount of facts available in the system; time constraints; and lack of impact on the final decision. This study contributes to both research and practice by increasing the understanding of what challenges are experienced in DSS use, since the findings can be used as a framework of challenges that should be addressed, in design of systems as well as method for use. The study also contributes to understanding the role of politicians in decision-making and the consequences for the use of DSS. Further, the literature study showed that there are overall very few studies on the actual use of DSS in a political context, and we therefore conclude by encouraging more studies reporting actual use.  相似文献

This article focuses on class blogs and presents results from 1:1 schools in Sweden. While Swedish schools are increasingly using Web 2.0 technologies (e.g., wikis and blogs), most of this use is still at an experimental stage. To further the understanding of how blogs are and can be used, we compare class blogs used in practice with the fast-growing literature in the field. Previous work suggests eight uses: collaboration, making assignments, journal writing, instruction, posting supplemental material, community building, external readers, and prompting. In practice, we found blogs to be used in a fairly narrow way—mainly for instruction and posting supplemental material. We hope that this article will inspire teachers to further their blog use.  相似文献

Six children with cerebral palsy and severe speech impairment took part in a two‐phase longitudinal study of development of social cognition. The children ranged in age from 5 to 7 years old at data collection time 1 and from nine to 11 years old at data collection time 2. Using a model of normal development of Theory of Mind (ToM) suggested by Gopnik and Slaughter (1991), the children were tested on a number of tasks requiring (ToM). The findings suggest that the children with speech impairment follow a normal pattern of development, but with a severe delay compared with children without disability. The results are discussed in relation to problems in early social and communicative experience for the group of children with cerebral palsy and severe speech impairment.  相似文献

The study draws on findings from a series of seven participatory action research projects in community care for older people carried out over a period of eight years in 20 municipalities in southern Sweden. The analysis here looks at social impact across administrative levels and geographical scales. Different professional groups and care workers in community care participated, crossing divides between social work and health care. The participatory methods all involved a phase of individual reflection, a phase of reflection in practice with colleagues and mixed groups at the regional level, including unit managers and directors in some stages. Impacts concerned interprofessional learning and improved conditions for collaboration in care for older people across institutional boundaries as well as organisational learning across the municipalities. The action research approach was characterised by intensive work with values, empowering low-status professional groups. Social impacts were achieved beyond each project by benefitting from the multi-stakeholder design, using the structure of the organisations and the regional R&D department of the Association of Local Authorities. Over time, the different projects thus contributed to regional development ‘from below’. Nevertheless, employer perspectives tended to determine which conclusions from the projects were eventually implemented and prioritised. Continued reflective dialogue meetings between professional groups are therefore, needed as part of regular work processes. Local and regional structures need forms of autonomy that allow them to implement recommendations from participatory projects. Finally, employee perspectives need to be reflected in decision-making at all levels, particularly including low-status groups of care staff.  相似文献

Although mentoring programs are increasing in popularity as a preventative intervention strategy for youth, little is known about the experience from the mentor’s perspective. In this study, we describe a longitudinal assessment of 41 mentors, including 13 men and 28 women (Mage?=?21.93?years, SD?=?3.21) working with at-risk youth in a school-based mentoring program. Before starting the program, mentor perceptions, motives, and efficacy were assessed and again after three and six months of mentoring to measure change across time. At the end of the program, mentors evaluated the relationship and rated perceived benefits. Mentors experienced significant changes in perceptions and efficacy across time and changes predicted relationship satisfaction and perceived benefits. Recommendations to support mentors and develop sustainable and satisfying mentoring relationships are provided.  相似文献

Educators and policymakers envision the future of education in Egypt as enabling learners to acquire scientific inquiry and problem-solving skills. In this article, we describe the validation of a model for problem solving and the design of instruments for evaluating new teaching methods in Egyptian science classes. The instruments were based on an established model for problem solving and were designed to assess seventh grade students’ problem solving, experimental strategy knowledge, achievement and motivation towards science. The test for assessing students’ knowledge has been developed based on the topic, density and buoyancy which will be taught in seventh grade in a later intervention study. The instruments were partly self-developed and partly adapted from newly performed studies on strategy knowledge and problem solving in Germany. All instruments were translated into Arabic; the translation process and quality control are described. In order to determine the quality of the instruments, 44 students in Egypt completed the questionnaires and tests. The study’s aim to develop and validate the instruments did require an ad hoc and typical sample which was drawn from an accessible population. Accordingly, the characteristics of the sample are described. Data were analysed according to the classical test theory, but to underpin the results, the instruments were additionally analysed using the even stronger Rasch model. The findings demonstrated the reliability of the items and aspects of validity. In addition, this study showed how test items can be successfully developed and adapted in an international study and applied in a different language.  相似文献

Lay conceptions of energy often conflict with scientific knowledge, hinder science learning and scientific literacy, and provide a basis for ungrounded beliefs. In a sample of Finnish upper secondary school students, energy was attributed with features of living and animate beings and thought of as a mental property. These ontologically confused conceptions (OCC) were associated with trust in complementary and alternative medicine (CAM), and independent of scientifically valid conceptions. Substance-based energy conceptions followed the correlational pattern of OCC, rather than scientific conceptions. OCC and CAM decreased both during the regular school physics curriculum and after a lesson targeted at the ontological confusions. OCC and CAM were slightly less common among students with high actively open-minded thinking, low trust in intuition and high need for cognition. The findings are discussed in relation to the goals of scientific education.  相似文献

ABSTRACT

This study describes multilingual students’ authentic use of their first and second languages in a translanguaging science classroom, from a sociocultural perspective. The study is ethnographic, and has followed some lessons each month in a translanguaging science classroom at a primary school for three years. The observed lessons were documented by four video cameras and four audio recorders, while field notes and different types of students’ texts and other teaching materials were also collected. In order investigate how language operates, and to realise the meaning semantically, we analysed the students’ use of both first and second language to tie paradigmatic relations, and how they move in linguistic loops between languages and discourses. The results illustrate the ways in which a translanguaging science classroom constitutes a resource in joint negotiations of the scientific content and its related language for multilingual students, and benefits the students’ ability to relate and contextualise the science content to prior experience. The creation of translanguaging science classrooms, in which students’ experiences and diverse cultural and linguistic resources interweave with school science, and in which multilingual students are enabled and encouraged to use all available language resources, has important implications for science education.  相似文献

The overriding aim of this article is to make a contribution to the discussion on individual development plans (IDPs) in Sweden as an expression of a regulated childhood and institutional practice. Individual development plans are seen as a phenomenon linked to the emergence of an auditing society. In sum, children are studied as subjects in relation to content, form and assessment in the individual development plans. The IDP material was collected in October 2006 in three urban municipalities and one rural municipality in southern Sweden. The three urban municipalities comprised municipal areas that were ethnically relatively homogenous and heterogenous, respectively. The data consist of 82 randomly chosen plans for children in preschool and preschool classes, and the method is based on textual analysis. An overall picture of a multicontextual regulation of childhood and institutional practice gradually emerges. The analysis can be summarized in distinctive principal tracks, or normalities, marked by equivalence with variation  相似文献

Awareness of the mechanisms underlying training and development (T&D) programmes is crucial in creating sustainable learning conditions in organisations. The organisational and psychosocial aspects of the work environment in Swedish elderly care is the focus of this longitudinal study, and the relation between process and results of a T&D programme is investigated. A mixed-methods design enabled exploration of the content of the quality improvement efforts, followed by an examination of how aspects of the work environment are influenced. The perceived learning climate, workload and resource adequacy are shown to be influenced differently by different contents. Insights into the complexity surrounding T&D programmes are then offered. It is concluded that even if a seemingly sound method of quality improvement is implemented, this is not enough to guarantee success. Also, it is apparent that changes may sometimes be at the expense of employees’ work environment, which may hamper continuous learning.  相似文献
