Set against the backdrop of a STEM-based (science, technology, engineering and mathematics) activity in a teacher education science methods class, the author examines the need for ethics education to be partnered with STEM education. To make the case, the origin of the STEM initiative, undertaken and strongly supported by both US government and corporate sources, is briefly recounted. The STSE initiative (science, technology, society and environment) is posited as a counterpoint to STEM. Also considered are: (a) an historical perspective of science and technology as these impact difficult individual and social decision making; (b) STEM knowledge generation considered through the lens of Habermas’ threefold knowledge typology; and (c) the experiences of the teacher candidates working through the STEM activity when an ethical challenge is posed. The author demonstrates the need for a moral component for science education and makes the case for a partnership between STEM and ethics education. Further, such a partnership has been shown to increase student enjoyment and motivation for their science studies. Three possible ethical frameworks are examined for their theoretical and practical utility in a science classroom. 相似文献

Computers play an important role in adolescent youth culture. This adolescent use of computers has much deeper implications than simply developing specific technical skills. Focusing on the relation between adolescent subjects and computers reveals three issues of particular interest: individual identity formation, self‐formation and ‘fluid’ forms of religion. The following is an overview of the main dimensions of these issues and their implications for religious education. All the results presented are related to a larger qualitative empirical research project on adolescents and computers. The final pedagogical conclusions in this paper are developed from a perspective of religious education within the Protestant tradition as it is practised within the German school system, but have wider implications. 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

ABSTRACTOne of the challenges of context-based science education is to construct high quality teaching materials. This paper presents results from a study investigating the heuristic value of an activity-based instructional framework for transformation of authentic scientific practices for use in the science classroom, in line with cultural historic activity theory (CHAT). The activity-based instructional framework was used to transform the authentic practice of Modelling Human Exposure and Uptake of Chemicals in Consumer Products into a curriculum unit. The transformation was conducted by experienced chemistry teachers well informed about CHAT. The heuristic value was judged on criteria completeness, instructiveness and appreciation. Collected data are designed curriculum materials and a focus group interview. Analysis of the designed curriculum materials indicated that the framework was highly complete and instructive, except for evoking reflection in students. Most important, the framework proved successful in operationalising CHAT into concrete guidelines for educational design. Additionally, the results show that the instructional framework is highly appreciated by the users. Further development of such instructional frameworks is important, since it fosters the construction of high quality context-based curriculum materials. 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

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

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

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
