English in action: school based teacher development in Bangladesh     

Tom Power  Robina Shaheen  Mike Solly  Clare Woodward  Sonia Burton 《Curriculum Journal》2013,24(4):503-529

In the Least Economically Developed Countries (LEDCs), School Based Teacher Development (SBTD) is sometimes advocated as a potential mechanism for improving the classroom practices experienced by millions of children in a complete school system, as quickly as possible. Robust evidence is required for approaches to be implemented with some confidence by Government development agencies, such as the UK Department for International Development (DFID). SBTD has a long history stemming from ideas of school-based curriculum development, which underlay the ideas on teacher-as-researcher, and is typically advocated in the developed world based on a view of the teacher as a professional. How might such notions play out, and to what effect, in LEDC contexts? This article examines the issues at stake in introducing SBTD in LEDCs, by examining: the nature of the evidence for various forms of teacher development, the nature of SBTD in particular and the evidence for its effectiveness. The latter issues will be illustrated through examination of English in Action (EIA, www.eiabd.com), a large-scale SBTD programme for primary and secondary English language (EL) teachers serving government schools across Bangladesh.  相似文献

I listen and I believe,I see and I understand: a collective reflection approach to understanding children's learning experiences     

Carmen Mohamed 《Education 3-13》2013,41(5):517-528

The project on which this report is based set out to establish how exploring children's musicality might encourage adults to consider their engagement with the musical play and learning of children under the age of five. Through reflection and evaluation the participants became aware that they were challenging their own teaching style in response to the children's exploratory learning. This became the central focus for the practitioners involved as it changed their understanding of their own practice. This paper endeavours to share the findings pertaining to the reflection, collaboration and change process of participants involved in the research project. It also describes practitioner involvement in this programme as an effective example of encouraging non-academic practitioners to take part in educational research.  相似文献   

课前指导与补充指导对学生网络学习的影响     

Richard Ng  Ahtar Kaur  Ramli Balbroom  王惠云 《天津电大学报》2009,13(2):17-22

马来西亚开放大学（OUM）90％以上的学生为在职人员。这些成年学生离开学校至少已经5年,而且大多数人的数学基础不好。因此,仅是在线学习加少量面授辅导的教学模式对他们来说还不能完全解决学习困难。学校试用了“课前指导工作室”与“补充指导”的教学方法,探讨了这一方法对学员的在线参与程度及考试结果的影响,运用源于探究团体模式的34项量表对在线论坛的内容进行了分析,结果表明,学员参加工作室与否同他们的期末考试成绩有很大关系。参加指导老师工作室及补充指导的学员与那些参加指导老师常规指导的学员相比,前者的在线参与程度及期末考试的平均分都存在着很大的差异。两组学员的数学探究团体模式平均分表明,两组学员在教学存在和认知存在方面有差异,但在社会存在方面基本相同。  相似文献

Probabilistic fuzzy logic controller for uncertain nonlinear systems     

Omar Shaheen  Ahmad M. El-Nagar  Mohammad El-Bardini  Nabila M. El-Rabaie 《Journal of The Franklin Institute》2018,355(3):1088-1106

This paper proposes a probabilistic fuzzy proportional - integral (PFPI) controller for controlling uncertain nonlinear systems. Firstly, the probabilistic fuzzy logic system (PFLS) improves the capability of the ordinary fuzzy logic system (FLS) to overcome various uncertainties in the controlled dynamical systems by integrating the probability method into the fuzzy logic system. Moreover, the input/output relationship for the proposed PFPI controller is derived. The resulting structure is equivalent to nonlinear PI controller and the equivalent gains for the proposed PFPI controller are a nonlinear function of input variables. These gains are changed as the input variables changed. The sufficient conditions for the proposed PFPI controller, which achieve the bounded-input bounded-output (BIBO) stability are obtained based on the small gain theorem. Finally, the obtained results indicate that the PFPI controller is able to reduce the effect of the system uncertainties compared with the fuzzy PI (FPI) controller.  相似文献   

The inculcation of generic skills among juveniles through Technical and Vocational Education     

Wan Azlinda Wan-Mohamed Mohamed Hafts Yunus 《美中教育评论》2009,6(4):56-61

Generic skills are skills which contribute towards individual＇s effective and successful participation in the workplace. For juveniles, Technical and Vocational Education （TVE） is one of the platforms that provide them generic skills which enable them to compete for job market. The purpose of this study is to investigate the level of generic skills that has been inculcated through TVE on juveniles in one of the juvenile schools in Malaysia, the time the teachers spent on inculcating the skills, and the challenges the instructors face in the process. There are four focuses of the generic skills that are of interest in this study： communication, teamwork, problem solving and technology. Eight teachers and 119 juveniles were chosen as the respondents from the Juvenile School （JS）. The data collected was through a set of questionnaires from the respondents, and these were analyzed by using frequency, percentage and mean score. The findings from this research show that the level of generic skills inculcated as perceived by the juveniles is at a moderate level. The perceived moderate level of skill acquire of the juveniles is justified by the moderate amount of time that the teachers believed they spend in instilling the generic skills. The teachers also suggested that the lack of understanding on what generic skills are is the main reason for not inculcating generic skills at its highest level. In conclusion, generic skills inculcation on juveniles through TVE in Juvenile School is at an average level. Measures have to be taken so that inculcation of generic skills can be increase to a higher level, as these generic skills will benefit juveniles in the labor force market.  相似文献   

Using cloud computing services in e-learning process: Benefits and challenges     

Abderrahim El Mhouti  Mohamed Erradi  Azeddine Nasseh 《Education and Information Technologies》2018,23(2):893-909

During the recent years, Information and Communication Technologies (ICT) play a significant role in the field of education and e-learning has become a very popular trend of the education technology. However, with the huge growth of the number of users, data and educational resources generated, e-learning systems have become more and more expansive in terms of hardware and software resources, and many educational institutions cannot afford such ICT investments. Due to its tremendous advantages, cloud computing technology rises swiftly as a natural platform to provide support to e-learning systems. This paper focuses on the research on the application of cloud computing in e-learning. The aim of this paper is to give an overview of the current state and the impact of the use of cloud computing for e-learning. Thus, at first the paper introduces concepts of e-learning and cloud computing infrastructure with their key characteristics. The paper analyzes also challenges facing e-learning systems deployment. In follow the paper considers cloud-based e-learning solutions by focusing on the raisons of the convenience of cloud computing for e-learning. Therefore cloud computing benefits are introduced as a solution for these challenges. Finally, the paper presents some solutions of cloud computing in e-learning and describes the most common architecture adopted. Issues in implementing cloud-based e-learning systems and some potential ways to overcome them are also discussed.  相似文献   

Transforming Growth Factor-β1/Smad3 Signaling and Redox Status in Experimentally Induced Nephrotoxicity: Impact of Carnosine     

Walaa Arafa Keshk  Mohamed Alaa Katary 《Indian journal of clinical biochemistry : IJCB》2017,32(1):19-25

Exposure to various organic compounds including drugs and environmental toxins causes cellular damage through generation of free radicals. Carnosine a dipeptide was used in this study to evaluate its effect against CCl4-induced nephrotoxicity. Sixty male albino rats were involved in this study and were equally divided into four groups. CCl4 (3 ml/kg body weight; biweekly for 4 weeks) was given to group II and III. Carnosine (10 mg/kg body weight; once daily for 4 weeks) was given to group III and VI. Transforming growth factor-β1 (TGF-β1) level by immunoassay and Smad3 mRNA level by real-time PCR were estimated in addition to cytochrome P450 2E1 (CYP2E1) activity, renal functions, redox status assessment and histopathological examination of the kidney. Carnosine significantly improved kidney function, renal redox status, decreased renal CYP2E1 activity, TGF-β1 level and Smad3 gene expression when compared to CCL4-intoxicated group. The protective effect of carnosine was confirmed by histopathological study. In conclusion: carnosine has the ability to protect against CCl4-induced nephrotoxicity possibly by alleviating oxidative stress, normalizing kidney histopathological architecture in addition to the disruption of the inflammatory and fibrotic response induced by CCl4.  相似文献   

Knowledge heterogeneity and social network analysis – Towards conceptual and measurement clarifications     

Mohamed El?LouadiEmail author 《知识管理研究与实践》2008,6(3):199-213

This literature review highlights some Social Network Analysis (SNA) concepts applicable to the study of organizational knowledge and, more particularly, to knowledge heterogeneity. Knowledge being all at the same time decentralized and distributed, knowing up to what point knowledge can be heterogeneous or homogeneous across organizational units becomes as important as the question of knowing how to structure the organization. SNA applied to knowledge management thus seems a stimulant for future research in the fields of management.  相似文献
