This paper presents an improved model for global sunshine duration estimation. The methodology incorporates geostationary satellite images by including snow cover information, sun and satellite angles and a trend correction factor for seasons, for the determination of cloud cover index. The effectiveness of the proposed methodology has been tested using Meteosat geostationary satellite images in the visible band with a temporal resolution of 1 h and spatial resolution of 2.5 km×2.5 km, for the Brue Catchment in the southwest of England. Validation results show a significant improvement in the estimation of global sunshine duration by the proposed method as compared to its predecessor (R ² is improved from 0.68 to 0.83, root mean squared error (RMSE) from 2.37 h/d to 1.19 h/d and the mean biased error (MBE) from 0.21 h/d to 0.08 h/d). Further studies are needed to test this method in other parts of the world with different climate and geographical conditions.  相似文献   

Attitudes toward Face-to-Face and Online Counseling: Roles of Self-Concealment,Openness to Experience,Loss of Face,Stigma, and Disclosure Expectations among Korean College Students     

Geoff J. Bathje  Eunha Kim  Ellen Rau  Muhammad Adam Bassiouny  Taehoon Kim 《International journal for the advancement of counseling》2014,36(4):408-422

This study examined attitudes toward face-to-face (f2f) and online counseling among 228 Korean college students. In addition, it tested a hypothesized model proposing that general propensities (i.e., self-concealment, openness to experience, and loss of face) would influence counseling-specific expectations (i.e., self-stigma and disclosure expectations), which, in turn, would predict attitudes toward f2f and online counseling. Findings mirrored the results of earlier studies revealing that self-concealment was negatively related to attitudes toward both f2f and online counseling, while openness to experience and disclosure expectations were positively related. However, whereas self-stigma was associated with negative attitudes toward f2f counseling, it was not related to attitudes toward online counseling. In addition, disclosure expectations accounted for f2f attitudes more than online attitudes.  相似文献   

Public Education and Muslim Voluntary Organisations in Britain     

Basil Mustafa 《International Journal of Research & Method in Education》2013,36(2):129-136

Since the beginning of their settlement in Britain, Muslims have had to face the challenges of adapting to a new social, cultural and economic environment, and also that of responding to the opportunities provided by the new environment. A particularly sticking challenge facing the Muslim community in Britain is in the field of education. Over the last four decades, a group of Muslim voluntary organizations has emerged which is characterised by its keen interest in the public education system of this country. Muslim voluntary organizations have been playing a key role in the educational debate pertaining to the nature of religious education, and the scope of moral and spiritual development in the school curriculum. In addition, these organizations have been active, through a process of consultation and collaboration, in providing educational services to state schools, local education authorities and government departments. This paper examines the development of such voluntary organizations and attempts to discern their role and impact on the public education system in Britain.  相似文献   

School Leadership in Pakistan: Exploring the Headteacher’s Role     

Tim Simkins  Charles Sisum  Muhammad Memon 《School Effectiveness & School Improvement》2013,24(3):275-291

There is a good deal of consensus in the literature about the key role of leadership – especially that of the headteacher – in facilitating school improvement. Yet much of the research in this area has taken place in Western industrialised countries. This article explores the issue of headship in the context of schools in a specific developing country context, that of Pakistan. Drawing on 2 studies of the experience of headteachers in Karachi, the article identifies and explores the key variables that may contribute to a sense of personal efficacy for these heads, namely the expectations generated by the national or community culture, the powers and accountabilities generated by the school system in which they work, and their own individual personalities and histories.  相似文献   

Pre-service teachers’ and teacher-educators’ experiences and attitudes toward using social networking sites for collaborative learning     

Kamal Ahmed Soomro  Ugur Kale  Sajid Yousuf Zai 《Educational Media International》2013,50(4):278-294

Extensive use of social networking sites by students and teachers makes educators and researchers to think whether they can be incorporated in instructional process to facilitate students’ learning. This survey-based study records and examines Pakistani pre-service teachers’ and teacher-educators’ current uses of Facebook, and their attitudes toward using Facebook for collaborative learning, and to see if there is a significant relationship between participants’ intensity of Facebook use and their attitude toward instructional use of Facebook. Results of the study indicated that pre-service teachers’ and teacher-educators’ motives for their current Facebook use are mainly limited for social purposes. Pre-service teachers’ use of Facebook is more intensified than the use of Facebook by teacher-educators. Further, pre-service teachers showed more positive attitudes toward using Facebook for collaborative learning than the attitudes of their faculty. Findings also indicated a positive relationship between participants’ Facebook intensity and their attitudes toward its use for collaborative learning.  相似文献

This study examines Black student and parental perceptions of exclusionary practices of Black school principals. I ask why students and parents viewed two Black principals as contributing to abusive and exclusionary school environments that marginalized Black students. After a two-year ethnographic study, it was revealed that exclusionary behaviors toward Black students—which was viewed as “abuse” by students and parents—was a reproduction of the district's racism, and thus adds new considerations for discussions around the value of racially-like (i.e., all Black) educators and students. Parents perceived these two Black principals as dealing more harshly and rigidly with the Black students and their families; moreover, analysis of the interview data revealed that the principals rejected the cultural and social capital, and proclivities of Black students, and blamed Black students for their lower achievement and unique behaviors. I draw significant attention to the larger contexts of White supremacy and racism as I examine how Black principals negotiate their own roles, how they understand their own treatment of urban Black students, and how they are (knowing or unknowingly) reproducing oppressive practices of White supremacy on Black students in school.  相似文献   

Effectiveness of conceptual change instruction on understanding of heat and temperature concepts     

Mustafa Baser  Ömer Geban 《Research in Science & Technological Education》2013,31(1):115-133

This study investigated the differential effects of two modes of instructional program (conceptual change oriented and traditionally designed) and gender difference on students' understanding of heat and temperature concepts, and their attitudes toward science as a school subject. The subjects of this study consisted of 72 seventh grade students from two General Science Classes taking the course from the same teacher. Each teaching method was randomly assigned to one class. The experimental group received reinforcement via the conceptual change texts while the control group utilized traditionally designed science texts over a period of four weeks. Analysis of covariance was used. Logical thinking ability was taken as a covariate. The results showed that the conceptual change oriented instruction produced significantly greater achievement in understanding of heat and temperature concepts. The result for science attitudes as a school subject showed no significant difference between the experimental and control groups. Also, no significant difference was found between the performance of females and that of males in terms of learning heat and temperature concepts and attitudes toward science, but the interaction of treatment regarding to gender was significant for learning the concepts. In addition, it was found that students' logical thinking ability accounted for a significant portion of variation in heat and temperature concepts achievement.  相似文献   

Effects of metacognitive instruction on mathematics achievement and attitude towards mathematics of low mathematics achievers     

Muhammad Maqsud 《Educational research; a review for teachers and all concerned with progress in education》2013,55(2):237-243

An experiment was conducted to examine the effects of metacognitive instruction on mathematics achievement and attitude towards mathematics of low mathematics achievers at a middle school in the North‐West Province of South Africa. Forty standard (std) 7 pupils were identified whose non‐verbal general ability and previous mathematics achievements were significantly lower than those of other std 7 pupils. These subjects were randomly assigned to an experimental group and a control group. Metacognitive strategies in solving mathematical problems related to four mathematics topics were individually taught to the members of the experimental group, while the pupils in the control group were taught the four mathematics topics through the conventional method of teaching mathematics. The comparisons of pretest and posttest measures of general ability, metacognitive awareness, attitude towards mathematics, and mathematics achievement revealed that the posttest scores of all the four variables for the experimental group were significantly higher than those for the control group.  相似文献   

Perceptions of college of education students in Turkey towards organizational justice, trust in administrators, and instructors     

Mustafa Kale 《Higher Education》2013,66(5):521-533

In this research, the perceptions of college of education students in Turkey regarding organizational justice, trust in administrators, and trust in instructors were determined. In the present study, the answers to three research questions were sought. The research was done using the survey method. After choosing six universities of various sizes and from different geographical regions, 1,872 students were selected randomly as participants. As data collection instruments, “The Organizational Justice Scale”, developed by Hoy and Tarter (Int J Educ Manag 18(4):250–259, 2004), and the “Student Trust in Principals” and “Student Trust in Faculty” scales, developed by Forsyth et al. (Collective trust, Columbia University, New York: Teachers College Press, 2011), were used after being translated into Turkish. The results show that while statistically significant mean differences are found between at least two groups (p < 0.05), there is a high positive relationship between organizational justice and trust in both administrators and instructors.  相似文献   

Educating and Training the Workforce to Work with People with Dementia: Two Projects from the United Kingdom     

Nageen Mustafa  Anna Tsaroucha  Nick Le Mesurier  Paul Kingston 《Educational gerontology》2013,39(6):398-412

Educating and training the dementia workforce is a global challenge, given the expected increasing number of people living with dementia across the world as the population ages. Two projects from the UK (one regionally and one locality based) investigated courses available to the workforce and mapped the content of identified courses against a locally developed dementia care pathway. The locality project included a survey of what percentage of staff time was spent with people living with dementia, and what percentage of staff caseloads were devoted to people living with dementia. There was a great variation in the extent of education and training available, with some stages of the dementia care pathway poorly addressed. An educational strategy for the dementia workforce in the UK might include four categories of education and training: basic dementia awareness, intermediate level, advanced level, and dementia awareness for managers. Staff requiring education and training might be divided into three groups: those employed to work specifically with people living with dementia and their families; those working with people who have other conditions but some of whom will have a coincidental dementia; those working with other conditions but in settings where a high proportion of their patients have a comorbid dementia. To improve workforce skills in dementia care will require actions across the whole of education and training for professionals and untrained workers who provide services to this group.  相似文献
