Can images provide contextual support for prose?     

Robert M. Bernard  Chris H. Petersen  Mohamed Ally 《Educational technology research and development : ETR & D》1981,29(2):101-108

This study sought to determine whether contextual organizers presented before prose passages can improve learning and retention among students who have no prior knowledge of the subject. The researchers used two types of organizers — an image and its verbal equivalent. Students who were provided the organizers scored better than control students on tests given two weeks later, but the predicted advantage of images over verbal learning adjuncts did not appear.  相似文献

AN EXPLORATION OF THE EDUCATIONAL RESILIENCE OF TEACHING STAFF – This study focuses on the degree of resilience displayed by teaching staff with the aim of promoting their professional development and preventing job-related exhaustion. Seven underprivileged schools in Montreal were selected, and 24 teaching staff with contrasting personal profiles were interviewed on the subject of their work. The Alceste software was used to analyse the conversations, which revolved around techniques applied when dealing with critical incidents. The main analysis identified five different discourses among the respondents. Three of these were associated with the more resilient of the teachers and two were associated with the more vulnerable ones. Resilient teaching staff characteristically discussed dealing with aggressive behaviour, the teaching-learning relationship and the subject of social relationships, whereas vulnerable teaching staff focused on work beyond the classroom, people in positions of higher authority and the community. The authors note that teachers who are just embarking on their careers appear more vulnerable than more experienced teaching staff, which suggests that more resources should be provided to support teachers in their profession.  相似文献   

Arab media,corporate communications,and public relations: the case of Al Jazeera     

Mohamed Zayani 《亚洲交流杂志》2013,23(3):207-222

Over the past few decades, public relations has developed significantly in the West into a sophisticated management function which is recognized as an integral part of any organization's attempt to communicate with various persons, both within and outside the organization, in order to achieve its goals and objectives. However, this is not the case in the Arab world where public relations remains underdeveloped and, even when practised, is relatively unsophisticated. This paper deals with the public relations function in a prominent though controversial Arab media organization: Al Jazeera Satellite Channel. It explores how Al Jazeera has been dealing with internal and external communication issues impelled initially by its role as a satellite broadcaster spearheading changes in a vibrant Arab mediascape and subsequently by its expansion into a global broadcaster. Drawing on James Grunig's four models of communication to analyze Al Jazeera's public relations practices, the case study at hand outlines some of the communication challenges and opportunities the organization has been facing during its 10 years of existence. The case of an indigenous organization like Al Jazeera operating in a culturally distinct environment puts into perspective communications issues and complicates our understanding of how public relations is understood and practised outside the normative Western public relations paradigm.  相似文献   

DESIGN, DEVELOPMENT AND VALIDATION OF A MODEL OF PROBLEM SOLVING FOR EGYPTIAN SCIENCE CLASSES

Educators and policymakers envision the future of education in Egypt as enabling learners to acquire scientific inquiry and problem-solving skills. In this article, we describe the validation of a model for problem solving and the design of instruments for evaluating new teaching methods in Egyptian science classes. The instruments were based on an established model for problem solving and were designed to assess seventh grade students’ problem solving, experimental strategy knowledge, achievement and motivation towards science. The test for assessing students’ knowledge has been developed based on the topic, density and buoyancy which will be taught in seventh grade in a later intervention study. The instruments were partly self-developed and partly adapted from newly performed studies on strategy knowledge and problem solving in Germany. All instruments were translated into Arabic; the translation process and quality control are described. In order to determine the quality of the instruments, 44 students in Egypt completed the questionnaires and tests. The study’s aim to develop and validate the instruments did require an ad hoc and typical sample which was drawn from an accessible population. Accordingly, the characteristics of the sample are described. Data were analysed according to the classical test theory, but to underpin the results, the instruments were additionally analysed using the even stronger Rasch model. The findings demonstrated the reliability of the items and aspects of validity. In addition, this study showed how test items can be successfully developed and adapted in an international study and applied in a different language.  相似文献   

Citizens as consumers: Profiling e-government services’ users in Egypt via data mining techniques   总被引：1，自引：0，他引：1  

Mohamed M. Mostafa  Ahmed A. El-Masry 《International Journal of Information Management》2013

This study uses data mining techniques to examine the effect of various demographic, cognitive and psychographic factors on Egyptian citizens’ use of e-government services. Data mining uses a broad family of computationally intensive methods that include decision trees, neural networks, rule induction, machine learning and graphic visualization. Three artificial neural network models (multi-layer perceptron neural network [MLP], probabilistic neural network [PNN] and self-organizing maps neural network [SOM]) and three machine learning techniques (classification and regression trees [CART], multivariate adaptive regression splines [MARS], and support vector machines [SVM]) are compared to a standard statistical method (linear discriminant analysis [LDA]). The variable sets considered are sex, age, educational level, e-government services perceived usefulness, ease of use, compatibility, subjective norms, trust, civic mindedness, and attitudes. The study shows how it is possible to identify various dimensions of e-government services usage behavior by uncovering complex patterns in the dataset, and also shows the classification abilities of data mining techniques.  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

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
