To frame is to explain: a deductive frame-analysis of Dutch and French climate change coverage during the annual UN Conferences of the Parties 总被引:1,自引:0,他引:1
This study examines the way Dutch and French newspapers frame climate change during the annual United Nations Conferences of the Parties. The methods used in previous studies on the framing of climate change do not allow for general cross-national comparisons. We conduct a quantitative deductive framing analysis on 257 quality Dutch and French newspaper articles between 2001 and 2007. Both countries' newspapers seem to frame climate change through mainly the same lens. The majority of the articles make reference to the consequences of the (non-)pursuit of a certain course of action and of possible losses and gains (consequences frame). Additionally, many articles mention the need for urgent actions, refer to possible solutions and suggest that governments are responsible for and/or capable of alleviating climate change problems (responsibility frame). Finally, the conflict frame was found to be used less often than the aforementioned frames, but more regularly than the human interest frame. 相似文献

Thirty-four undergraduate public relations majors participating in a problem-based service-learning project at a Hispanic-Serving Institution executed an event that attracted more than 100 low-income Hispanic families to campus. The purpose was to help parents prepare their children for college. From primary and secondary research, the students identified 3 dimensions for reaching the targeted audience—mirroring, trust, and cultural alignment—which were dubbed the Reaching Back strategy. Our purpose is to describe how the Reaching Back strategy works, the benefits of problem-based service-learning projects for both students and community participants, and how this strategy can be replicated. 相似文献

ABSTRACT Interdisciplinary training for doctoral students is an emerging scenario in higher education. The learning relations of knowledge transfer (KT: transferring knowledge from one person to another) and knowledge integration (KI: integrating or synthesizing perspectives from different disciplines) built by doctoral students play an important role in the process of interdisciplinary training. This study explores how doctoral students from a wide range of disciplines build learning relations of KT and KI during online interdisciplinary training. A mixed-methods approach was applied. First, longitudinal social network analysis (SNA) was employed to investigate the patterns of KT and KI relations over a seven-month training period. Subsequently, interviews were conducted to triangulate the SNA findings. SNA results show that the establishment of KI relations is significantly less than that of KT. Qualitative results show three themes explaining the challenges of KI relations, including challenges of online settings, the design of the training modules, and student involvement. Practical implications are drawn for the improvement of online interdisciplinary training, such as suggestions to promote KI and strategies for group learning. 相似文献

AbstractThe validity of traditional opinion-based student evaluations of teaching (SETs) may be compromised by inattentive responses and low response rates due to evaluation fatigue, and/or by personal response bias. To reduce the impact of evaluation fatigue and personal response bias on SETs, this study explores peer prediction-based SETs as an alternative to opinion-based SETs in a multicultural environment. The results suggest that statistically significant fewer respondents are needed to reach stable average outcomes when peer prediction-based SETs are used than when opinion-based SETs are used. This implies that peer prediction-based SETs could reduce evaluation fatigue, as not all students would need to do each evaluation. The results also report that the peer prediction-based method significantly reduces the bias evident in the opinion-based method, in respect of gender and prior academic performance. However, in respect of the cultural variables, race and home language, bias was identified in the peer prediction-based method, where none was evident in the opinion-based method. These observations, interpreted through the psychology literature on the formulation of perceptions of others, imply that although peer prediction-based SETs may in some instances reduce some personal response bias, it may introduce the perceived bias of others. 相似文献

Producing Knowledge for Living 总被引:1,自引:1,他引:0

Work is still associated predominantly with employment. A lot of studies focus on the link between learning and labour, but there are few investigations of what kind of knowledge is produced in the act of creating and sustaining life. This is not surprising as subsistence production is not valued as much as work that generates profits. The daily backbreaking work of poor people and women is best captured from the perspective of livelihood systems. These are constantly adjusted and they vary from one person, household or community to another. Working knowledge defined in terms of livelihood activities includes knowing how local hierarchies are tied up in larger socio-political structures, how indigenous herbs can be used for healing, and how communal resources should best be managed so that they serve the interests of all. The paper uses a case study from a village in Zimbabwe to illustrate how the collective actions of a community resulted in learning that led to the rehabilitation of a community dam and a plan for sustainable management of this asset. In this way, villagers could diversify their activities, and thus become less vulnerable to hazards such as drought. The paper suggests that educators have a role in helping villagers to ask the right questions in the process of making really useful knowledge for living. 相似文献

Exploring a Framework for Professional Development in Curriculum Innovation: Empowering Teachers for Designing Context-Based Chemistry Education 总被引:1,自引:0,他引:1

Involving teachers in early stages of context-based curriculum innovations requires a professional development programme that
actively engages teachers in the design of new context-based units. This study considers the implementation of a teacher professional
development framework aiming to investigate processes of professional development. The framework is based on Galperin’s theory
of the internalisation of actions and it is operationalised into a professional development programme to empower chemistry
teachers for designing new context-based units. The programme consists of the teaching of an educative context-based unit,
followed by the designing of an outline of a new context-based unit. Six experienced chemistry teachers participated in the
instructional meetings and practical teaching in their respective classrooms. Data were obtained from meetings, classroom
discussions, and observations. The findings indicated that teachers became only partially empowered for designing a new context-based
chemistry unit. Moreover, the process of professional development leading to teachers’ empowerment was not carried out as
intended. It is concluded that the elaboration of the framework needs improvement. The implications for a new programme are
discussed. 相似文献

Biological maturation is associated with physiological changes which in turn affect motor performance. No study has assessed the association between growing up habitually shod versus habitually barefoot and motor performance in the context of maturation, so this approach is unique. The purpose of this study was to examine the influence of biological maturity on motor performance dependent on the participants’ footwear habits. Sixty-five German habitually shod (mean age 13.28?±?0.83 years) and fifty-five South African habitually barefoot (mean age 13.38?±?0.87 years) participants were included. Dynamic postural control was determined via backward balancing, explosive strength by standing long jump and sprinting performance based on a 20-m sprinting test. All tests were performed barefoot and shod. Biological maturation was calculated by using the maturity offset value. Linear mixed models were used to analyse interactions between the maturity offset value, footwear habits and motor performance. Throughout maturation, there was a significant difference between habitually barefoot and habitually shod balance performance (P?=?0.001). Maturation led to balance improvements in habitually barefoot adolescents, but not in habitually shod adolescents. No such differences could be observed for standing long jump and 20-m sprint performance. Maturity offset was a significant predictor for jumping and sprinting performances (P?0.001), independent of being habitually barefoot or habitually shod. Better performances could be observed in more mature subjects. Biological maturation seems to be a relevant predictor for motor performance characteristics for the jumping and sprinting performance in adolescents. 相似文献

Since many preservice teachers (PTs) display anxiety over teaching math and science, four PT educators collaborated to better understand the PTs’ background experiences and attitudes toward those subjects. The research project provided two avenues for professional learning: the data collected from the PTs and the opportunity for collaborative action research. The mixed method study focused on: the relationship between gender and undergraduate major (science versus non-science) with respect to previous and current engagement in science and math, understanding the processes of inquiry, and learning outside the classroom. A field trip to a science center provided the setting for the data collection. From a sample of 132 PTs, a multivariate analysis showed that the science major of PTs explained most of the gender differences with respect to the PTs’ attitudes toward science and mathematics. The process of inquiry is generally poorly interpreted by PTs, and non-science majors prefer a more social approach in their learning to teach science and math. The four educators/collaborators reflect on the impacts of the research on their individual practices, for example, the need to: include place-based learning, attend to the different learning strategies taken by non-science majors, emphasize social and environmental contexts for learning science and math, be more explicit regarding the processes of science inquiry, and provide out-of-classroom experiences for PTs. They conclude that the collaboration, though difficult at times, provided powerful opportunities for examining individual praxis. 相似文献
