Tradition or Modernity? The Fallacy of Misplaced Concreteness Among Women Science Educators in Cameroon     

Howard Woodhouse 《Interchange》1997,28(2-3):253-262

Building on an earlier article in which I analyzed the views of women scientists and science educators in Cameroon, West Africa (Woodhouse & Ndongko, 1993), I reflect upon the ways in which these same science educators managed to commit the fallacy of misplaced concreteness, attributed by Alfred North Whitehead to the abstractions of 17th-century physics.On the one hand, the women in our study tried to make their science teaching as concrete as possible by introducing examples from African traditional medicine that were familiar to their students. On the other, they undermined these laudable efforts by consistently diminishing the value of traditional indigenous healing, for they regarded the abstractions of scientific methodology as real in a way that such treatments were not. I argue that this is a prime example of the fallacy.Furthermore, the only way in which these women science educators could imagine that African traditional healers would be accepted by the scientific community was to become professionals by adopting the abstract methodology of science, which falls foul of the fallacy in the first place. Only then could their various traditional treatments be assimilated to the market and developed commercially by multinational corporations. I argue that this overlooks the ways in which such corporations appropriate the cultural and intellectual property of traditional healers in Cameroon and elsewhere. Moreover, their reasoning is based once again on the fallacy of misplaced concreteness, accepting the abstractions of the market as real, while disregarding the value of indigenous knowledge itself.  相似文献   

Infants’ and Young Children's Imitation of Linguistic In‐Group and Out‐Group Informants          下载免费PDF全文

Lauren H. Howard  Annette M. E. Henderson  Cristina Carrazza  Amanda L. Woodward 《Child development》2015,86(1):259-275

Although children can use social categories to intelligently select informants, children's preference for in‐group informants has not been consistently demonstrated across age and context. This research clarifies the extent to which children use social categories to guide learning by presenting participants with a live or video‐recorded action demonstration by a linguistic in‐group and/or out‐group model. Participants’ (N = 104) propensity to imitate these actions was assessed. Nineteen‐month‐olds did not selectively imitate the actions of the in‐group model in live contexts, though in‐group preferences were found after watching the demonstration on video. Three‐year‐olds selectively imitated the actions demonstrated by the in‐group member regardless of context. These results indicate that in‐group preferences have a more nuanced effect on social learning than previous research has indicated.  相似文献

Effect of gear ratio on peak power and time to peak power in BMX cyclists     

Lee P. Rylands  Simon J. Roberts  Howard T. Hurst 《European Journal of Sport Science》2017,17(2):127-131

The aim of this study was to ascertain if gear ratio selection would have an effect on peak power and time to peak power production in elite Bicycle Motocross (BMX) cyclists. Eight male elite BMX riders volunteered for the study. Each rider performed three, 10-s maximal sprints on an Olympic standard indoor BMX track. The riders’ bicycles were fitted with a portable SRM power meter. Each rider performed the three sprints using gear ratios of 41/16, 43/16 and 45/16 tooth. The results from the 41/16 and 45/16 gear ratios were compared to the current standard 43/16 gear ratio. Statistically, significant differences were found between the gear ratios for peak power (F(2,14)?=?6.448; p?=?.010) and peak torque (F(2,14)?=?4.777; p?=?.026), but no significant difference was found for time to peak power (F(2,14)?=?0.200; p?=?.821). When comparing gear ratios, the results showed a 45/16 gear ratio elicited the highest peak power,1658?±?221?W, compared to 1436?±?129?W and 1380?±?56?W, for the 43/16 and 41/16 ratios, respectively. The time to peak power showed a 41/16 tooth gear ratio attained peak power in ?0.01?s and a 45/16 in 0.22?s compared to the 43/16. The findings of this study suggest that gear ratio choice has a significant effect on peak power production, though time to peak power output is not significantly affected. Therefore, selecting a higher gear ratio results in riders attaining higher power outputs without reducing their start time.  相似文献   

Introduction To The Theme of This issue: Competencies in Audio-Visual Education     

Howard Hitchens 《Educational Media International》2013,50(2)

The theme for this issue was originally envisioned by the planners as the general topic of professional education; it has developed down to the more specific area of competencies in audiovisual education. Education and training programs for specialists in the educational media profession world-wide vary a great deal. Some countries are unable to provide more than on-the-job training for educators who have been selected or who desire to work in this speciality; while some very sophisticated programs exist such as at the Centre Audio-Visuel at St Cloud in Paris, the Centre for Educational Technology in the United Kingdom, or some of the institutions in the United States.  相似文献

CENTRAL AGENCY RENEWAL AND EDUCATIONAL GOAL SETTING

The infrequently used label mishshamshim baKodesh may well capture the essential life-style most needed, and authentic, for bureaus of education; central agencies for Jewish education in communities whose variant demographics and structure mandate a caveat for generalizations.  相似文献
