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

This study is aimed at identifying and determining the percentage of occurrence frequency of cellulose decomposing soil fungi. The soil samples were inoculated into culture plates prepared in Sabouraud medium under sterilized conditions and incubated at 30 ℃ for 4 to 7 d. The identified fungal species were incubated in self-designed cellulose medium for testing their cellulolytic ability. Forty-two species, including2 nova species, representing sixteen genera showed growth and sporulation in the cellulose medium. Most of the isolated species were from genus Aspergillus and Penicillium. Aspergillus niger and Mucor hiemalis showed highest occurrence frequency （45% and 36% respectively）, as these species were collected from about 80% of soil samples. Being agar free and cheaper, the new fungal medium designed showed results equivalent to Sabouraud medium. 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

This article traces the desegregation of South African schools, particularly within the Gauteng region, from 1990 to 1996. It argues that there is a discernible shift from ‘race’ to ethnicity in the educational discourses of South Africa and that at school level the response to ethnicity has been predominantly assimilationist. Attempts to move towards a more multicultural way of operating are affected by conceptions of identity as stereotyped, homogenised and generalised, leading to ‘bad’ multicultural approaches being adopted. Simultaneously, within official enunciations at national level, a consistent anti‐racist stance is emphasised in order to ‘redress’ apartheid's legacies. I argue that such initiatives are limited due to their structurally functionalist underpinnings and their failure to address the complexity of identities contained within the classifications of ‘black’ and ‘white’. I argue that, on both the macro and the micro level, questions of identity and difference are central in developing a school (and societal) environment that is not only free from racism, but other forms of discrimination too. 相似文献

In this paper, the stability analysis of impulsive discrete-time stochastic BAM neural networks with leakage and mixed time delays is investigated via some novel Lyapunov–Krasoviskii functional terms and effective techniques. For the target model, stochastic disturbances are described by Brownian motion. Then the result is further extended to address the problem of robust stability of uncertain discrete-time BAM neural networks. The conditions obtained here are expressed in terms of Linear Matrix Inequalities (LMIs), which can be easily checked by MATLAB LMI control toolbox. Finally, few numerical examples are presented to substantiate the effectiveness of the derived LMI-based stability conditions. 相似文献

This paper explores the premise that environmental education involves raising environmental consciousness rather than simply knowing about the environment in a technical-rational manner and acting for it in mechanistic prescribed ways. The paper draws on educational theory and data from a phenomenological case study of educators working together at an outdoor education centre in urban Canada, whose practice of environmental education we believe can best be described as environmental consciousness raising. Based on our study’s findings, we suggest that raising environmental consciousness involves connecting people to their environment, fostering care for the environment, and building agency for the environment. Educating for environmental consciousness also requires providing people with deeply engaging experiences that afford authenticity, multidimensionality and serendipity. Our study shows how these features can work to raise environmental consciousness, by creating epiphanies or moments when sudden expansions of the self, realization and empowerment become possible. 相似文献
