The educative goal of citizenship education through science education converges to the declared purpose of the SSI research movement. Socioscientific issues formulated in science education research covering topics as biotechnology, environmental issues, sustainable development, energy choices, have been introduced in French Middle Schools. But citizenship is often not clarified and can be multiple. After having clarified who is the citizen targeted by SSI research movement, the concept of citizen in the French curriculum needs to be clarify. What do these citizens have in common with the citizen that a sociology literature review let see oscillating between obedience and critical thinking has also been investigated. The paper also looks at the teachers’ views and their contribution to citizenship education through socioscientific topics described in the national curriculum. From the analysis, different teachers’ views of citizenship education have been highlighted: a normative citizenship education in connection with civility and rules and an emancipatory citizenship education to develop pupils’ skills such as searching and evaluating information, argumentation and critical thinking in order to enable pupils to build their own argued opinion and to participate to public debates. This last emancipatory view of citizenship education is congruent with the aim of social empowerment within the SSI research movement.  相似文献

Research has increasingly shown that school principals exercised a significant role in teacher professional development (TPD). Nevertheless, the insights into the particular influence they exert in this process and how it is exercised still need to be developed. This article focuses on what school principals consider important working conditions for TDP and which leadership practices they use to realise these conditions in their schools. Using a multiple case study design, including 20 semi‐strcutured interviews with primary school principals, the findings show that they consider both structural (sufficient time and evaluation of TDP interventions) and cultural (an open work climate and collaboration) conditions to be important for TDP. Additionally, school principals emphasise the significance of teachers’ learning attitudes, differentiation in professionnalisation efforts and knowledge sharing in their schools. Furthermore, the results highlight that they have trouble in realising these working conditions, especially those for internal learning activities (such as an open work climate). Based on the results, recommendations are made for further research and policy makers concerning the preparation and support that principals need to realise (internal) TDP in their schools.  相似文献

Efforts have been devoted to introduce in science curricula direct instruction for evaluating scientific reports on socioscientific issues. In this study, students’ opinions on the SSI of mobile telephones effects have been investigated before and after a classroom activity designed to enable students to assess scientific data. Aspects of the nature of science raised by students interpreting available contradictory research evidence and making personal decision on this SSI have also been documented. Results indicated the central role of considerations of scientific evidence in students’ decision making. Students tended to over-attribute significance to empirical processes in justifying viewpoints on the SSI of mobile phones and in suggesting how scientific disputes might be resolved.  相似文献

This paper aims at understanding the complex relations between bureaucratic literacies, the lives of young people in a situation of precarity and the work of employees of two community-based organisations in Québec (Canada). Drawing on the perspective of the New Literacy Studies, the focus of this article is around the role of literacy mediators that can play youth workers. It also endeavours to clarify the meaning of the term precarity (précarité) by suggesting a multidimensional perspective on it. This paper reveals that literacy mediation can be a form of powerful literacies that offer opportunities to counteract dominant literacies and support new ways of learning. Finally, it suggests a reflection on the importance of the work of community-based organisations in countering the situation of precarity experienced by some young people. It underlines the fact that these organisations are also experiencing financial uncertainty and insecurity that affect their services.  相似文献

Abstract

The purpose of this study was to determine the effects of stride length variations on ratings of perceived exertion (RPEs) in experienced recreational runners. Twenty-eight male college students were randomly divided into equal-sized treatment and control groups. The treatment group performed five 15 min altered stride length runs, each separated by a minimum of 48 hr. The five trials involved running with a freely chosen stride length (FCSL) and a FCSL altered by +14%, +7%, ?14%, and ?7%. The control group was utilized to monitor changes in subjects' RPEs as a result of practice effects developed through repeated bouts of treadmill running. Results revealed that the treatment group's local and general RPEs for the over striding runs (+14%, +7%) were significantly greater (p < .01) than RPEs recorded during the FCSL run. Additionally, there was a marginally significant difference (p < .05) in local RPEs between the FCSL run and the extreme understriding run (?14%). Analysis of variance on the control group's RPE data suggests that neither local nor general RPEs changed significantly in repeated FCSL runs across the six-week testing period. The results of this study suggest that experienced recreational runners perceive differences in exertion accompanying changes in stride length.  相似文献

Abstract

The purpose of this study was to examine variations in ground reaction forces and selected lower extremity kinematics during the stride and swing phases of batting. High speed photography (100 fps) employing direct linear transformation methodology and a force plate were used to record three-dimensional kinematic and kinetic data for 7 female fast pitch softball batters. Mean vertical forces (Fz) of the right or rear foot increased to approximately 1 BW during the stride. Once the left or forward foot made contact with the ground after completion of the stride, right Fz forces decreased to .43 BW while left Fz forces rapidly increased to 1.6 BW at contact. The mean decrease in right Fz forces from peak force until contact was 55%, and the ratio of left to right Fz forces; at impact was 3.67:1. Right mediolateral forces (Fx) were exerted laterally, away from the batter, and were responsible for initiating movement of the body toward the pitched ball. As the left foot made contact with the ground at completion of the stride, left Fx forces were exerted laterally toward the pitched ball. The reaction to these forces retarded the batter's forward momentum, increased stability, and caused the left hip and knee to extend as contact approached. Right and left anteroposterior forces (Fy) acted in opposite directions (right foot pushing backward, left foot pushing forward), and were responsible for rotating the hips and upper body in a counterclockwise direction toward the pitched ball. Horizontal angular deceleration of both thighs just prior to contact was due, in part, to a decrease in these forces. These data may prove helpful when attempting to identify atypical batting patterns, and when considering improvements in shoe design. In the latter instance, force production and stability may be enhanced by aligning the cleats along the lines of action of the applied resultant shear forces.  相似文献

Writing retreats are structured events during which a group of people write in the same room over several days. In this paper, we report on findings from a study exploring the impact of writing retreats on PhD students’ writing and their sense of self as academic writers. A second aim of the study was to contribute to the search for appropriate pedagogies to support writing at the PhD level. The data consist of interviews with 19 PhD students who had taken part in writing retreats as well as evaluations and pre- and post-retreat reflections by these students. In the interviews, we discussed the role of writing retreats in the context of the students’ wider biographies as writers and how it relates to their experiences of writing. Our findings suggest that writing retreats can be important events for PhD students positively affecting their relationship with literacy [Besse, J.-M. 1995. L’écrit, l’école et l’illettrisme. Paris: Magnard]. Taking part in a retreat generates pleasure, emphasising the role of emotions in academic writing. Writing retreats and the opportunities they offer students to write and to reflect on their experiences as writers are a valuable part of PhD training.  相似文献

ABSTRACT

This article offers an alternative point of view on the perspectives that large-scale literacy surveys provide on refugee women by presenting the case of Darya, a young Afghan woman who moved to Canada as a refugee in 2009. It also presents how a community-based organisation for young people addressed Darya’s literacy and identity curation practices, and life situation in their everyday activities. The original study this paper is based on adopted an ethnographic and participatory approach. For the purpose of this paper, only the data relating to Darya was retained and analysed using a thematic analysis approach. The findings illustrate how exploring the intersections between gender, race, and religion is a fruitful lens to adopt in order to understand young refugee and migrant women’s literacy learning and practices. The data suggest that the community-based organisation provided a positive space not just for literacy learning but also for important identity work. It did so by 1) grounding its activities in young people’s lives and practices, 2) aiming to foster confidence building and autonomy, 3) being open to multilingualism and multimodality, and 4) focusing on young people’s futures. The findings also illuminate the need to train youth workers about cultural responsiveness.  相似文献

Immigrants from the Comoros Islands constitute a closely-knit community in Marseille, where they interact in the Quartiers Nord with the North African community, which is larger in number, which arrived generally a generation earlier, and whose children continue to underachieve at school. It is commonly expected that the Comorians will adjust better to school because of their tight communal organization and because of their specific needs for educational achievement. These needs are thought to relate to the money needed to return to the Comoros and to finance their children's marriage ceremonies there. In our study, pupils of Comorian origin in the senior primary school years displayed more positive attitudes toward the academic aspects of schooling than did pupils of North African origin. For both Algerians and Comorians, positive aspects of friendship quality were associated with better attitudes toward school. In-group friendships were more common than friendships with members of other ethnic groups. In-group friendships were of higher quality than friendships between members of different groups. Comorian children whose best friends were from outside their ethnic group were those with more negative attitudes toward school; the reverse applied to Algerians.  相似文献

Nanotechnology has been touted as the next ‘industrial revolution’ of our modern age. In order for successful research, development, and social discourses to take place in this field, education research is needed to inform the development of standards, course development, and workforce preparation. In addition, there is a growing need to educate citizens and students about risks, benefits, and social and ethical issues related to nanotechnology. This position paper describes the advancements that have been made in nanoscale science and nanotechnology, and the challenges that exist to educate students and the public about critical nanoscience concepts. This paper reviews the current research on nanotechnology education including curricula, educational programs, informal education, and teacher education. Furthermore, the unique risks, benefits and ethics of these unusual technological applications are described in relation to nanoeducation goals. Finally, we outline needed future research in the areas of nanoscience content, standards and curricula, nanoscience pedagogy, teacher education, and the risks, benefits, and social and ethical dimensions for education in this emerging field.  相似文献
