Summaries English An attempt has been made to describe how curriculum developers in science in Zimbabwe have endeavoured to cater for the decision by government, at a stroke, to treble the intake of secondary school pupils and how the developers have, at the same time, attempted to employ the new situation as an opportunity to introduce the kind of science programme in schools which they believe to be appropriate to the conditions which obtain in a developing country like Zimbabwe. The practical, economic, philosophical, political and cultural issues which have been raised in the exercise have been outlined as well as the strategies that have been adopted, wherever possible, to meet them. Implications with international relevance have been highlighted. 相似文献

Agricultural research is mostly a public undertaking. In Israel, as in many other countries, farmers participate in the finance of research through taxes imposed by farm organizations on the marketed products. Farmers contribution ranges from 8% of research outlay in tomatoes to 79% in cotton. Strength of organization and ease of collection were the major factors affecting this share. In general, as inflation eroded the real value of government's finance, the farmers increased their share.Representatives of farmers' organization participate in the bodies that approve grants to proposed research projects. It was found that the higher the share of farmers' finance the larger the part of short-term research directed at immediate outcomes and the smaller the part of long-term, more basic research.The tendency of the farmers to prefer short-term, applicable research may reflect both their familiarity with practical problems and a comparatively high degree of risk aversion.It is not clear how farmers' participation in the direction of research, which is based on their financial contribution, affects the efficiency of resource allocation to the agricultural sciences. 相似文献

Interaction and gender — Findings of a microethnographical approach to classroom discourse 总被引：1，自引：0，他引：1
Helga Jungwirth 《Educational Studies in Mathematics》1991,22(3):263-284
The aim of the present study is to reconstruct teacher-student acting to find out whether there are gender-specific methods of managing classroom situations and gender-related patterns of interaction. The findings reveal that over the long run the gender of the participants is immaterial. There are, however, gender-related modifications of the ordinary interaction patterns. They result from gender-specific practices on the part of the students and from the corresponding actions on the part of the teachers. Five types of gender-related modifications have been reconstructed. The methods which enable students to participate successfully in the interaction process have become more common for the boys than for the girls. Therefore the boys appear more mathematically competent than the girls. 相似文献

In this study, we examined the relative control of reaction time and force in responses of the lower limb. Fourteen female participants (age 21.2±1.0 years, height 1.62±0.05?m, body mass 54.1±6.1?kg; mean±s) were instructed to exert their maximal isometric one-leg extension force as quickly as possible in response to an auditory stimulus presented after one of 13 foreperiod durations, ranging from 0.5 to 10.0?s. In the ‘irregular condition’ each foreperiod was presented in random order, while in the ‘regular condition’ each foreperiod was repeated consecutively. A significant interactive effect of foreperiod duration and regularity on reaction time was observed (P?<?0.001 in two-way ANOVA with repeated measures). In the irregular condition the shorter foreperiod induced a longer reaction time, while in the regular condition the shorter foreperiod induced a shorter reaction time. Peak amplitude of isometric force was affected only by the regularity of foreperiod and there was a significant variation of changes in peak force across participants; nine participants were shown to significantly increase peak force for the regular condition (P?<?0.001), three to decrease it (P?<?0.05) and two showed no difference. These results indicate the independence of reaction time and response force control in the lower limb motor system. Variation of changes in peak force across participants may be due to the different attention to the bipolar nature of the task requirements such as maximal force and maximal speed. 相似文献

This study aims to explain the reasons for the transformation of women's news in contemporary China. It concludes that in comparison with women news's in the Maoist period, present-day women's news is represented in a fragmented way. This article analyses the differences among the individual, professional, and institutional aspects in news production, while emphasizing the complicated interaction among feminism, state, and market to illuminate the reasons behind women's news transformation. Due to the immanent masculinity of both state and market, feminism in China has to face a state–market complex, that is, double pressure. Comparing with state and market, the influence from feminism to journalism is quite weak and there is a long way to go before feminism realizes its own agenda for media transformation. 相似文献

Summaries English ‘Integrated science’ as an aspect of curriculum development is now well established world‐wide and has become the subject of international meetings. This article tries to put forward for discussion some ideas about the meaning of integration among the sciences. Integration is first discussed in its relation to common culture and disciplinary knowledge. Disciplinarity, recognized as the way in which scientific knowledge has been organized, is seen as the only real possibility for the growth of knowledge. To understand the meanings and the importance of different disciplinary fields, is a didactical objective to be reached through an articulated educational process starting in the primary school. However, another objective of the same importance is the development of the capacity to recognize and utilize disciplinary knowledge for the solution of ‘real’ problems. In this perspective, an important problem for educational research is the definition of a ‘scientific knowledge for all’ which should enable people to confront real problems with a knowledge of the meanings of science, and of where to find and how to use scientific information. 相似文献

Abstract A battery of tests was administered to three trial groups who studied the Israel BSCS Adaptation Program for several years. Compared with non-BSCS students the performance and progress of the BSCS students in three cognitive areas, namely biological knowledge, inquiry skills and the understanding of science, demonstrates the feasibility of the BSCS adaptation program for students in academic city schools as well as for those in the Kibbutz rural schools. It is less adequate for most students in agricultural schools as well as for a considerable number of students of non-European descent. The results indicate that achievement in biology is not unidimensional and that different students reach different levels of achievement with different measures. The implications of the findings regarding program revision, teacher training, adoption as well as further research are discussed. The study may be helpful to other countries which either have adapted or considered the adaptation of programs such as the BSCS. 相似文献
