The general background of this study is an interest in how digital tools contribute to structuring learning activities. The
specific interest is to explore how such tools co-determine students’ reasoning when solving word problems in mathematics,
and what kind of learning that follows. Theoretically the research takes its point of departure in a sociocultural perspective
on the role of cultural tools in thinking, and in a complementary interest in the role of the communicative framing of cognitive
activities. Data have been collected through video documentation of classroom activities in secondary schools where multimedia
tools are integrated into mathematics teaching. The focus of the analysis is on cases where the students encounter some kind
of difficulty. The results show how the tool to a significant degree co-determines the meaning making practices of students.
Thus, it is not a passive element in the situation; rather it invites certain types of activities, for instance iterative
computations that do not necessarily rely on an analysis of the problems to be solved. For long periods of time the students’
activities are framed within the context of the tool, and they do not engage in discussing mathematics at all when solving
the problems. It is argued that both from a practical and theoretical point of view it is important to scrutinize what competences
students develop when using tools of this kind.

Research on induction of newcomers is primarily focused on individual processes, such as acquisition of knowledge and socialization
in order to create a smooth and frictionless entry period. The interest of our research, however, is the processes that happen
on the organizational level. We claim that induction potentially triggers both individual and organizational learning and by drawing on practice-based theory we discuss how the interplay between individual and the organization,
what we call a generative dance, ignites both kinds of learning. We focus on and describe the interplay that takes place in particular induction events and
analyze the “dance” through the lens of learning. The article concludes with a brief discussion about the implications for
practitioners and the challenges and future research prospects we have encountered. We draw on an empirical enquiry in two
organizational settings, a Danish management consulting company and a German retail bank.

ABSTRACTWe assess Mureithi's 2009 documentary, ICYIZERE: hope (Motion Picture, Josiah Films), as a document of representational space and collective memory. We argue that the post-genocide reconciliation workshop represented in the film embodies and constructs a sacred/secular space. The reconciliatory space is produced through (1) negotiations of dialectical tensions between past/present as well as individual/collective memory, and (2) (re)presentations of rehumanization within the workshop whereby participants (and audiences) can (re)interpret the Other. We analyze the rehumanization process in the documentary via identity widening theory (Ellis, D.G., 2006, Transforming conflict: Communication and ethnopolitical conflict. Boulder, CO: Rowman & Littlefield Publishers) and empathetic human interaction. Finally, we detail how the documentary situates participants within a transformative space of negotiated memories of the genocide with current day reconciliation efforts. 相似文献

ABSTRACTThis paper presents an action research project that aimed to increase opportunities for multilingual literacy engagement and identity investment for newly-arrived immigrant students in Norway. A language teacher and a researcher jointly developed a cross-curricular, multilingual module focusing on identity texts written in three languages: English, Norwegian, and each student's home language. Fourteen adolescent students speaking 15 different home languages participated. To assess the effectiveness of the multilingual pedagogical practices, the data collected included a language use questionnaire, student reflection logs, students’ identity texts, lesson plans, and the teacher's notes and reflections. The results suggest that explicit emphasis on including all languages in students’ linguistic repertories can help build inclusive classroom spaces and foster learners’ multilingual identities. 相似文献

Adopting a mixed method design, this paper explores the configuration and evolution of work values of 64 young adults in transition from education to employment. Qualitative analyses point out the existence of four categories of work values: interesting tasks, good relationships, self-fulfillment, and attractive work conditions. Quantitative analyses show that work values are questioned during the school-to-work transition, refined according to the experience of labor market integration, and partially different according to gender, education type, and the quality of the integration process. Consequently, career counseling should integrate a deeper understanding of what clients consider as important in their work lives. 相似文献

Background: From previous research among science teachers it is known that teachers’ attitudes to their subjects affect important aspects of their teaching, including their confidence and the amount of time they spend teaching the subject. In contrast, less is known about technology teachers’ attitudes.
Purpose: Therefore, the aim of this study is to investigate Swedish technology teachers’ attitudes toward their subject, and how these attitudes may be related to background variables.
Sample: Technology teachers in Swedish compulsory schools (n = 1153) responded to a questionnaire about teachers’ attitudes, experiences, and background.
Methods: Exploratory factor analysis was used to inwvestigate attitude dimensions of the questionnaire. Groupings of teachers based on attitudes were identified through cluster analysis, and multinomial logistic regression was performed to investigate the role of teachers’ background variables as predictors for cluster belonging.
Results: Four attitudinal dimensions were identified in the questionnaire, corresponding to distinct components of attitudes. Three teacher clusters were identified among the respondents characterized by positive, negative, and mixed attitudes toward the subject of technology and its teaching, respectively. The most influential predictors of cluster membership were to be qualified for teaching technology, having participated in in-service-training, teaching at a school with a proper overall teaching plan for the subject of technology and teaching at a school with a defined number of teaching hours for the subject.
Conclusions: The results suggest that efforts to increase technology teachers’ qualifications and establishing a fixed number of teaching hours and an overall teaching plan for the subject of technology may yield more positive attitudes among teachers toward technology teaching. In turn, this could improve the status of the subject as well as students’ learning. 相似文献

ABSTRACTSweden has one of the most marketised and decentralised school systems in the world while also ranking amongst countries with the highest levels of access to technology in classrooms. Considering the increasingly central role that digital platforms play in the practices of schooling, this article speculates on what might happen during the 2020s in highly decentralised school systems like Sweden’s. Based on current trends in education, directions indicated by platformisation in other contexts and taking a critical speculative approach, it offers a discussion of what could happen to the practices of schooling and the public mission of education. This discussion is intended to raise important questions for researchers, educators and policy makers to consider as the platformisation of schooling unfolds. 相似文献

The purpose of this article is to develop a method of approach that can be used to explore the meaning and use of artifacts
in education by applying a socio-cultural perspective to learning and artifacts. An empirical material of video recorded physical
education lessons in Sweden is used to illustrate the approach in terms of how artifacts in different ways can play a part
in meaning making processes in physical education. The illustration from the video recordings shows that a ball can be constituted
as a great toy and that in the practice of physical education being physically active and an active participant in a certain game is regarded
as reasonable. However, it also illustrates that the ball can be constituted as a lethal projectile and a pupil positioned as lazy and unwilling. In the article we argue that empirical studies of artifacts-in-use using visual
methodologies are both important and valuable, challenging physical education teachers’ reflections about the role of artifacts
in their teaching. 相似文献

SEAD method estimates the direction-of-arrival angles on an uniformly linear array based on the difference between the two largest singular values, what is called differential spectrum. Although it presented an outstanding performance, the ability to indicate the source positions was not elucidated yet. Inspired by the differential spectrum formulation we derived a total differential spectrum and found out that the matrix norm induced by the vector 2-norm of a modified spatial covariance matrix can be used to estimate the direction-of-arrival of multiple plane waves. Indeed we show that matrix norms are estimators and we propose their use instead of the singular value decomposition in SEAD-based methods. We present a general mathematical expression in order to explicit the operating principles of the proposed methods. Consequently, we were able to explain how the relation between the arriving and the search angles produces the larger peaks on the differential spectrum. To evaluate the important role played by matrix norms, a thousand experiments were carried out. They showed that the proposed approach proved to be as accurate as the previous SEAD-based methods, while providing a significant reduction on runtime. It also outperformed well-established methods like MODEX regarding the estimation error. 相似文献

Background:Team-sport players have a particularly high injury risk.Although female sex is considered a risk factor,it is still unknown whether female and male team-sport players,in fact,differ in their injury rates.We aimed to compare injury rates between female and male players by systematically reviewing and meta-analyzing injury surveillance studies of both sexes in order to evaluate sex-specific differences in team-sport injuries.Methods:Studies that prospectively collected injury data for high-level female and male players(age≥16 years)in basketball,field hockey,football(soccer),handball,rugby(union and sevens),and volleyball were included.Two reviewers(AZ and ALR)independently assessed study quality and extracted data for overall,match,training,and severe injuries(>28 days’time loss)as well as data regarding injury locations and types.Incidence rate ratios(IRRs)were pooled in a meta-analysis,and meta-regression analysis was performed when 10 or more studies were available.Results:Of 20 studies,9 studies reported injury data from football,3 studies from rugby,3 studies from handball,1 study from basketball,1 study from field hockey,2 studies from volleyball,and 1 study from basketball and field hockey.For overall injuries,the pooled IRR=0.86(95%confidence interval(95%CI):0.76-0.98)indicated significantly more injuries in male than in female players.For injury location,the pooled IRR showed higher injury rates in male athletes than in female athletes for upper extremity,hip/groin,thigh,ande foot injuries.Female players had a significantly higher rate of anterior cruciate ligament injuries(IRR=2.15,95%CI:1.27-3.62)than male players.No significant sex-specific differences in IRR were found for match,training,severe injuries,concussions,or ankle sprains.Conclusion:Our meta-analysis provides evidence for sex-specific differences in the injury rates in team sports.Further epidemiological studies including both sexes in sports other than football are needed in order to strengthen the evidence. 相似文献
