In democratic societies, it is becoming increasingly common for the government to formulate science education policies and programmes to reform education. In Alberta, Canada, government policies on education, including science, have been formulated on the basis of unprecedented public consultation. However, in the implementation of these policies, the initially proposed senior high science programme ran counter to views on science education held by academic scientists, technologists and academic high school science teachers. By garnering public support and applying political pressure, these groups were successful in forcing the government to re‐examine its science education policies and draft programmes. This review resulted in changes in the programme design and, more significantly, in the processes used to develop the science curriculum. This paper examines the complexity of reforming science education, and the dynamic tension and conflict that can develop between curriculum experts and academic scientists in the development of science programmes that meet broad education goals. 相似文献

Three of the most prevalent developmental disorders (DDs) are autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD) and fetal alcohol spectrum disorder (FASD). As part of a study screening for DDs in Greater Manchester, UK, a unique opportunity was taken to explore parents' experiences of receiving reports about their child's previously unrecognised DD. Six parents out of a possible 16 took part in interviews, which were analysed thematically. Findings drawn from parental responses revealed a number of barriers to accessing support for their child's additional needs, including perceived resistance from schools, particularly for quiet, well-behaved girls, and difficulty in accessing assessment or referrals. There needs to be greater awareness of additional needs in children without externalising behaviours, the presence of gender-specific differences in the presentation of DDs, and FASD as a commonly occurring DD. Ultimately, better support for children with DDs would reduce the burden of unmet needs for the children and their families, and for wider services. 相似文献

A method for model order reduction is proposed using response-matching technique. The step and impulse inputs have been considered. All types of pole configurations in the original high-order and reduced low-order system are included in this paper like real, complex and repeated. The proposed method is comparable in quality with similar existing methods and is capable of generating a reduced-order model with a desired pole pattern. 相似文献

The purpose of this study was to estimate the optimal body size, limb-segment length, girth or breadth ratios for 100-m backstroke mean speed performance in young swimmers. Sixty-three young swimmers (boys [n = 30; age: 13.98 ± 0.58 years]; girls [n = 33; age: 13.02 ± 1.20 years]) participated in this study. To identify the optimal body size and body composition components associated with 100-m backstroke speed performance, we adopted a multiplicative allometric log-linear regression model, which was refined using backward elimination. The multiplicative allometric model exploring the association between 100-m backstroke mean speed performance and the different somatic measurements estimated that biological age, sitting height, leg length for the lower-limbs, and two girths (forearm and arm relaxed girth) are the key predictors. Stature and body mass did not contribute to the model, suggesting that the advantage of longer levers was limb-specific rather than a general whole-body advantage. In fact, it is only by adopting multiplicative allometric models that the abovementioned ratios could have been derived. These findings highlighted the importance of considering somatic characteristics of young backstroke swimmers and can help swimming coaches to classify their swimmers and enable them to suggest what might be the swimmers’ most appropriate stroke (talent identification). 相似文献

Pakistan is an underdeveloped country, full of socio-economic problems where a few oppress and exploit many. One of the most significant reasons, in this context, is the high illiteracy rate in the country. However, can high literacy rates guarranty peace, prosperity, and justice in any society? Clearly, not. There are several countries where the literacy rate is very high yet it remains relatively under-developed. However, it is also a fact that the countries where the literacy rate is high have been able to emerge as economic powers. In this regard, Freire’s concept of literacy education is very helpful in that it is essentially hopeful in nature and it is this optimism which gives it the potential to transform oppressive situations. 相似文献
