We show that boys still have a greater access to the space for interaction in science classrooms, which is unexpected since in Sweden today girls perform better in these subjects than boys. Results from video-recorded verbal communication, referred to here as interaction, show that the distribution of teacher–student interaction in the final year of lower secondary school follows the same patterns as in the 1980s. The interaction space for all kinds of talk continues to be distributed according to the two-thirds rule for communication in science classrooms as described by previous research. We also show that the overall interaction space in science classrooms has increased for both boys and girls when talk about science alone is considered. Another finding which follows old patterns is that male teachers still address boys more often than girls. This holds true both for general talk and for talk about science. If a more even distribution of teacher–student interaction is desirable, these results once again need to be considered. More research needs to be undertaken before the association between girls’ attitudes and interest in science in terms of future career choice and the opportunity to participate in teacher–student interaction is more clearly understood. 相似文献

In this study, the implementation of the Swedish first teacher reform, where especially skilled teachers get an opportunity to advance in their careers, is examined. The scene is an upper secondary school, Baxter High, in the southwest of Sweden. In this particular school, a new system with first teachers replaces an old system of so-called head teachers. The teachers’ response to this is multilayered: at the same time as it reveals an unwillingness to change everyday work rhythms, it is also a response to cultural change, and to change in the discourse of political life in Baxter High. The implementation of the first teacher reform results not only in a change in administrative categories, but also in a change in ideology, intertwined with and embedded in the cultural and social life of the school. In this article, the authors connect the first teacher reform to the neoliberal transformation process that the Swedish educational system has undergone over the last three decades. 相似文献

This is part of a larger ethnographical study concerning how school development in a local educational context sets cultural and social life in motion. The main data in this article consists of semi-structural interviews with teachers (facilitators) who have the responsibility of carrying out a project about formative assessment in upper secondary schools in the south of Sweden. The focus of the study is how the teachers make meaning of their position as facilitators and leaders, how they handle their fellow teachers’ criticism and resistance, how power transforms professional and human relationships, and how complex and weakly articulated power results in conflicting and ambivalent possibilities for action. From our perspective, the resistance the facilitators meet, although the project makes use of a concept that has proved to be successful, reveals an ambivalent structure where the facilitators have to face contradictory demands from different stakeholders. 相似文献

The aim of this study was to investigate whether kinematic proximal-to-distal sequencing (PDS) and speed-summation are common characteristics of both partial and full-swing shots in golf players of different skill levels and genders. A total of 45 golfers participated, 11 male tournament professionals, 21 male and 13 female elite amateurs. They performed partial shots with a wedge to targets at three submaximal distances, 40, 55 and 70 m, and full-swing shots with a 5 iron and a driver for maximal distance. Pelvis, upper torso and hand movements were recorded in 3D with an electromagnetic tracking system (Polhemus Liberty) at 240 Hz and the magnitude of the resultant angular velocity vector of each segment was computed. The results showed a significant proximal-to-distal temporal relationship and a concomitant successive increase in maximum (peak) segment angular speed in every shot condition for both genders and levels of expertise. A proximal-to-distal utilization of interaction torques is indicated. Using a common PDS movement strategy in partial and full-swing golf shots appears beneficial from mechanical and control points of view and could serve the purpose of providing both high speed and accuracy. 相似文献

School governance reform in post-apartheid South Africa has been used instrumentally to democratise schooling and to calibrate governance functions to accommodate diverse school contexts. Through an analysis of relevant sections in legislation, the author shows how the reform was structured to allow for representative democracy and partnerships. But, drawing on two recent studies, she contends that the governance reforms failed to include measures that prevent a re-enactment of traditional South African power relations of race, class and gender at schools, and apartheid-era inequalities continue to manifest in schools. The author concludes that in general democratic school governing bodies have fallen short of the transformation vision. 相似文献

This article explores the effects of certain discourses as they relate to sexual harassment in a Swedish higher education setting. Using a semiological perspective, the author analyzes notions of existence, range, prevention, and stability in order to demonstrate the way they aim at signifying a limited and, from a bureaucratic point of view, legitimate reality of sexual harassment. The empirical material consists partly of material drawn from public policies, legal documents, and research reports on sexual harassment in higher education, and partly of fourteen semi‐structured interviews with equal opportunity practitioners responsible for implementing equality legislation at a Swedish university. A semiological view on the construction of sexual harassment in public texts and ordinary speech is given through an analysis of the use of language and the internal and external relations of signs. By focusing simultaneously on the stable and variable aspects of the sign, interpretations of the specific notions of limitation, variability, and experience are put forward as critical tools aimed at changing normative views of sexual harassment. 相似文献

Using self‐generated analogies has been proposed as a method in a constructivist tradition for students to learn about a new subject, by use of what they previously know. We report on a group exercise on using self‐generated analogies to make sense of two thermodynamic processes, reversible adiabatic expansion and free adiabatic expansion of an ideal gas. The participants (N = 8) were physics preservice teacher students at the fourth year of the teacher education program. A main finding was that work with self‐generated analogies tended to be accompanied by the students assuming ownership for their learning, manifested in terms of actions of choice and control and the use of exploratory talk. Consequently, several self‐generated analogies were elaborated and developed to a high‐order relational structure. However, we also found that with the use of self‐generated analogies in science teaching follows the risks of developing idiosyncratic explanations of the encountered phenomena or getting stuck in overly complex comparisons. Sammanfattning: Självgenererade analogier har förts fram som en metod i en konstruktivistisk tradition för att elever och studenter ska kunna lära sig något nytt genom att relatera till vad de redan vet. Vi redogör här för en gruppövning där självgenererade analogier användes för att förstå två termodynamiska processer: reversibel adiabatisk expansion, respektive fri adiabatisk expansion av en ideal gas. Åtta (N = 8) lärarstudenter på fjärde året av utbildningen med inriktning mot fysik på gymnasiet deltog i studien. Ett viktigt resultat var att vid arbete med självgenererade analogier tenderade studenterna att ta ägandeskap för sitt lärande, vilket tog sig uttryck i handlingar såsom aktiva val, kontroll över processen och explorativ dialog. Som en följd utvecklades flera av de självgenererade analogierna till ett stort strukturellt djup. Samtidigt såg vi att vid skapande av egna analogier löper studenter risken att utveckla egna förklaringar av de studerade fenomenen som inte svarar mot dem inom vetenskapen eller snärja in sig i alltför komplexa jämförelser. © 2012 Wiley Periodicals, Inc.

It has been argued that user participation is important when public authorities develop e-services. At the same time there is limited research on the usefulness of existing user participation approaches in public e-service development. In this paper we, therefore, analyze how the three user participation approaches – participatory design, user-centered design, and user innovation – meet the strategic e-service goals of the EU and the US. In doing so, we identify three challenges that need to be considered when choosing among these approaches: 1) unclear user target segments can impede the fulfillment of usability and relevance goals, 2) the nature of participation can impede the fulfillment of democracy goals, and 3) lack of adequate skills can impede the fulfillment of efficiency goals. 相似文献

Use of self-generated analogies has been proposed as a method for students to learn about a new subject by reference to what they previously know, in line with a constructivist perspective on learning and a resource perspective on conceptual change. We report on a group exercise on using completion problems in combination with self-generated analogies to make sense of two thermodynamic processes. The participants (N = 8) were preservice physics teacher students at the fourth year of the teacher education program. The students experienced challenges in accounting for the constant entropy in reversible, adiabatic expansion of an ideal gas and the constant temperature in free, adiabatic expansion of an ideal gas. These challenges were found to be grounded in the students’ intuitive understanding of the phenomena. In order to come to terms with the constant entropy in the first process, the students developed idiosyncratic explanations, but these could by properly adjusted given suitable scaffolding. In contrast, the students by themselves managed to make sense of the constant temperature in free expansion, by use of microscopic explanatory models. As a conclusion, self-generated analogies were found to provide a useful approach to identifying challenges to understanding among students, but also for the students to come to terms with these challenges. The results are discussed against a background of different perspectives on the issue of conceptual change in science education. 相似文献

This article describes the Swedish initiative of municipal technology centres from a gender point of view. These centres provide after‐school technology education for children aged 6–16. By means of an ethnographic study, the effects of the use of single‐sex groups in increasing the interest of girls and boys in technical activities have been studied at one of the centres. The importance of the gender of the teacher relative to the gender of the pupils is also considered. The results show that single‐sex groups meant different things to boys and girls, and that the teachers’ way of “doing” femininity and masculinity, respectively, in the different groups was of some importance. The results indicate that single‐sex groups alone do not break down gender barriers. However, there are lessons to be learnt from a leisure‐time activity that provides a different setting from that of single‐sex science education in ordinary schooling 相似文献
