Initiation, response and follow-up (IRF) exchanges produced by a student and his tutor in an internet-based tutorial interaction have been analysed in terms of the multifunctional characteristics of each utterance. Different functions, related to different purposes, were observed in the IRF moves performed by the student. The control over the interaction was shared by both student and tutor. The simultaneous and interwoven occurrence of different chains of IRF exchanges is suggested as a typical structural feature of tutoring via the internet which helps us to account for the distinctive nature of teaching and learning dialogues using e-mail. 相似文献

ABSTRACT This article explores the interface between lifelong learning policies and the definition of social vulnerability of young adults in two regions located within the European Union. Girona comprises a constellation of small towns with important industry, service and hospitality sectors. Vienna is a global city where many key international operators are based and employ a large number of highly qualified professionals. The article explores to what extent the meta-governance and the ‘causal narratives’ of lifelong learning policies contribute towards shaping the prevailing images of youth vulnerability in these regions. In Girona, bureaucratic governance patterns lifelong learning policies, which strongly rely on the potential of career guidance to encourage the youth to undertake further education. Correspondingly, policy designs and professional discourses emphasise that the beneficiaries previously failed at school. In Vienna, authorities govern lifelong learning by means of both bureaucracy and complex networks of employers and non-profit organisations. The ‘causal narrative’ of the policies straightforwardly claims that all youth must have an experience with employment, whether in apprenticeships or in transitional workshops that emulate real jobs. There, policies portray beneficiaries according to their capacity to undertake and finish apprenticeships. 相似文献

ABSTRACTThis study explores the use of digital videos in education, from the perspective of the teacher as an agent of technological integration. Secondary and university teachers were surveyed in a region-wide case study. Three topics were specifically surveyed: common uses of digital video in teaching, instructor self-production of educational videos, and preferences in common presentation formats (chalk-and-talk, screencast, PowerPoint, demonstration and whiteboard writing). Results show that secondary teachers make more use of digital video and are more innovative than university teachers. Video self-production is scarce, though respondents declare a positive attitude, with time constraints and technical qualification as main reported obstacles. Preferences in video presentation formats reveal notable differences between secondary and university teachers for some formats. Preferences are also moderately influenced by the teacher’s knowledge field, and by experience with ICT and video production. 相似文献

AbstractThis article discusses an analysis of abstracts of Brazilian theses and dissertations on environmental education from a database organised and maintained by a group of researchers in the EArt Project (www.earte.net). In presenting extracts of key trends in this dataset, our aim is to provide a snapshot of the many possible approaches to, and histories of, Brazilian environmental education research. The data also allow us to raise some questions that explore possible ‘blank spots’, ‘blind spots’ and ‘bald spots’ in Brazilian research on environmental education. Given the temporal development of the research field since the 1980s, we illustrate these ‘spots’ by exploring data related to epistemological and methodological diversity, from the viewpoint of knowledge areas as well as the graduate programmes that have been developing research on environmental education. Finally, we draw a picture of the methodological trends that have been privileged by Brazilian researchers, and pose questions as to what is needed in shaping an agenda for research on environmental education in Brazil into the future. 相似文献

For the last 10 years, online pre-service teacher distance education has increased significantly in Brazil. As a result, research on this educational modality has also increased, in particular, research investigating the different roles students and teachers play in these courses. The purpose of this paper is to analyze the role of digital technologies in two specific contexts: how teachers, tutors, and students play a role in producing interactive digital didactic material and how digital technologies themselves can play a role in teaching distance learning courses. But for these roles to emerge, we point to the need for participants of online courses to interact collaboratively. To identify these roles, grounded theory, a branch of qualitative research, was used as the two roles were articulated. Data were produced from virtual observations in virtual learning environments and virtual interviews. The results stress that both highlighted roles are related. They transform teacher and student roles and participation in the virtual classroom, and an “agency of media” emerges in online mathematics education. 相似文献

ABSTRACT Covid-19 is a global public health crisis, which in addition to making victims is changing the living habits of the population. The objective of this study was to investigate the impacts of social isolation on the physical and mental health of older adults and to learn how they are informing themselves about the pandemic. It is a qualitative study with a phenomenological basis, composed by telephone interviews with 35 older adults (70,5 ± 4,7 years) of both genders, members of a Brazilian University of Third Age, during the period of the pandemic. The testimonies revealed a considerable degree of concern about the possibility of being infected by the virus, increased anxiety due to tragic news, the growing number of deaths, the collapse of the Brazilian economy and the rising unemployment rate. The group reported sleep disorders, joint pain, loss of appetite, weight loss, and reduced functional capacity. Everyone felt sufficiently informed about Covid-19. The main means of gaining information about the pandemic was radio, followed by TV, dialogue with family and friends, and WhatsApp. Only 30% of the participants used WhatsApp, praised because of its multiple functions and the ability to re-read the news. 相似文献

Post-scandal effects in public management point to the occurrence of overcompliance in the work of public managers, leading to reluctance and paralysis in decision-making. This article discusses the proposition of an artifact in the form of a warning system to aid the analysis process and issuing of opinions (APIO) by public managers, providing more information and, consequently, less risk and fear. The Design Science Research method was used to exapt a scientific artifact to the context of public management. The textual structure of 178 opinions issued by public agencies was analyzed, as was the perception of 17 public managers of the characteristics of the APIO. Exaptating the artifact from a technological perspective is simple and feasible, as it involves processes with strong functional similarities. The greatest challenges to operationalize the artifact broadly and without restrictions, as occurs in scientific academia, are associated with informational behaviors. 相似文献

The aim of the present study was to determine which approach to calculating shoulder ratios is the most sensitive for determining shoulder torque imbalance in handball players. Twenty-six participants (handball athletes, n = 13; healthy controls, n = 13) performed isokinetic concentric and eccentric shoulder internal rotation (IR) and external rotation (ER) assessment at 60, 180 and 300°/s. We used eight approaches to calculating shoulder ratios: four concentric (i.e. concentric ER torque divided by concentric IR torque), and four functional (i.e. eccentric ER torque divided by concentric IR torque) at the velocities of 60, 180 and 300°/s for both IR and ER, and combining 60°/s of ER and 300°/s of IR. A three factorial ANOVA (factors: shoulder ratios, upper limb sides, and groups) along with Tukey’s post-hoc analysis, and effect sizes were calculated. The findings suggested the functional shoulder ratio combining 60°/s of ER and 300°/s of IR is the most sensitive to detect differences between upper limbs for handball players, and between players and controls for the dominant side. The functional shoulder ratio combining 60°/s of ER with 300°/s of IR seems to present advantages over the other approaches for identifying upper limb asymmetries and differences in shoulder torque balance related to throwing. 相似文献

This article discusses the implications of the contemporary transition from a solid modernity to a liquid modernity for school physical education, according to the metaphors adopted by the Polish sociologist and English resident Zygmunt Bauman. By leveraging Bauman's sociological theory, this article pursues two aims: (1) to examine how physical education was forged by the characteristics of solid modernity and (2) to demonstrate how the cultural dynamics of contemporary bodily practices can be analyzed and interpreted based on the characteristics of the so-called liquid modernity. The article further argues that the contours of liquid modernity indicate the need for a ‘culturalist turn’ in physical education, which would mean giving up a model requiring universal claims of solid modernity. Finally, the article concludes with some reflections on the need to revise the social mandate of school physical education, as well as on some of the challenges that must be faced by this field. 相似文献
