Views of Omani post-basic education students about religious and cultural tolerance     

Ahmed Hamad Al-Rabaani 《Cambridge Journal of Education》2018,48(1):87-101

The study aims to investigate the views of Omani post-basic education students (Grades 10–12) about religious and cultural tolerance. The sample consisted of 1390 male and female students in grades 10, 11 and 12, from four of Oman’s seven regions. A questionnaire was used to gather data, which consisted of 27 items divided into five domains. The results showed that students place a strong emphasis on the importance of religious and cultural tolerance, both within Oman society and worldwide. They are also not in favour of any type of aggression, religious and cultural symbols or the fuelling of disagreements between religions or cultures. The results also indicated that female students are more strongly concerned with tolerance than males, grade 12 students more concerned than those in grades 10 and 11, and students from Muscat more concerned than those in other less urban areas.  相似文献   

Maarif: transformation of a concept in the Ottoman Empire at the beginning of the nineteenth century     

Aytaç Yıldız  Mustafa Gündüz 《History of education》2019,48(3):275-296

During the Ottoman period, ‘science (ilim, pl. ulûm)’, ‘knowledge (marifet, pl. maarif)’ and ‘technique (fen, pl. fünûn)’ emerged as three important concepts of knowledge. Maarif, which came into prominence with Selim III, began to undergo a semantic transformation together with the concepts of ulûm and fünûn and by the time of Mahmud II it had become an overarching concept representing the knowledge dimension of the new era. This article discusses the semantic transformation of maarif, focusing on the period between 1789 and 1839. This study applies the history of concepts approach developed by Reinhart Koselleck, whereby a synchronic analysis of the concept of maarif is undertaken alongside an examination of its diachronic dimension. This reveals an ambiguous and multi-dimensional structure and helps us to account for its evolution as an umbrella term.  相似文献   

Principals' and teachers' attitudes and knowledge of inclusive education as predictors of effective teaching practices in Ghana     

Ahmed Bawa Kuyini  Ishwar Desai 《Journal of Research in Special Educational Needs》2007,7(2):104-113

Surveys and observations were undertaken in selected primary schools in Ghana to determine whether principals' and teachers' attitudes towards and knowledge of inclusive education, as well as principals' expectations of teachers in implementing inclusion, were predictors of effective teaching practices in their classrooms. The sample of 128 educators (20 principals and 108 teachers) drawn from 20 primary schools in two districts, were required to respond to questionnaire measures of Attitude Towards Inclusive Education Scale (ATIES), Knowledge of Inclusive Education Scale (KIES) and Principals' Expectations Scale (PES). Of the total number of teachers ( N  = 108), 37 were observed during instructional delivery in their classrooms. The data were analysed by a variety of statistical procedures including Regression Analysis and Discriminant Function Analysis. In the context of the Theory of Planned Behaviour (Ajzen, 1985), the results showed that whilst attitudes towards inclusion (attitude element) and knowledge of inclusion (perceived behavioural control element) predicted effective teaching practices, principals' expectations (subjective norm) did not. Implications for the implementation of effective inclusive practices in Ghanaian schools and the need for future research are discussed.  相似文献

The major players in adaptive immunity     

Asma Ahmed  Banishree Saha  Anand Patwardhan  Shwetha Shivprasad  Dipankar Nandi 《Resonance》2009,14(5):455-471

How do we remain healthy, for the most parts, in the midst of an environment teeming with opportunistic and infectious microbes, potential carcinogens and allergens? The fact is that our immune system, by and large, does a fine job in protecting us. It is therefore important to understand the organization of the immune network, which is broadly categorized into two groups: innate and adaptive. Cells involved in innate immunity are the first to come into contact with invading microbes, similar to the border security force, and respond rapidly but in a non-specific manner. On the other hand, the cells involved in adaptive immunity are slower to respond but act in a very specific manner. Though the primary response is slow, the secondary response is much faster and demonstrates memory. This article will focus on some important features and key players involved in the adaptive immune response. The first part deals with the humoral immune response mediated mainly by immunoglobulins produced by the B cells. The second part deals with T cells, the Major Histocompatibility Complex (MHC)-encoded molecules, and Recombination Activating Genes (RAG) responsible for generating diverse B-cell receptors (BCR) and T-cell receptors (TCR). With the advent of newer and smarter infectious agents, it is important to understand the working of the immune network as more research in this area may facilitate the development of better protective strategies.  相似文献   

An investigation of mathematics anxiety among sixth through eighth grade students in Turkey     

Osman Birgin  Mustafa Baloğlu  Hakan Çatlıoğlu  Ramazan Gürbüz 《Learning and individual differences》2010,20(6):654-658

The purpose of the present study is to investigate mathematics anxiety among 220 sixth through eighth grade Turkish students in terms of mathematics achievement levels, perceived enjoyment of the mathematics teaching method, perceived enjoyment of mathematics, and perceived help with mathematics from parents. The Mathematics Anxiety Scale for Primary School Students (Bindak, 2005) was used to assess the levels of mathematics anxiety. A 3 × 2 factorial analysis of variance results showed that there was not a significant interaction effect or main effect of gender; however, there was a significant main effect of grade level. Standard multiple regression analyses show that independent variables accounted for 63% to 70% of variability in the dependent variable. The results also indicate that not only the perceived enjoyment of mathematics, but also the enjoyment of the mathematics teaching method and help with mathematics from parents had a significant effect on mathematics anxiety.  相似文献   

Investigating the Relationships Among Elementary School Students’ Epistemological Beliefs, Metacognition, and Constructivist Science Learning Environment   总被引：1，自引：0，他引：1  

?zgül Yilmaz-Tüzün  Mustafa Sami Topcu 《Journal of Science Teacher Education》2010,21(2):255-273

The research questions addressed in this study were: what types of epistemological beliefs do elementary students have; what types of metacognition do elementary students have; and what are the relationships among students’ perceived characteristics of constructivist learning environment, metacognition, and epistemological beliefs. A total of 626 students enrolled in sixth, seventh, and eight grades of nine elementary public schools located in Ankara, Turkey constituted the participants of this study. Constructivist learning environment survey (CLES), Junior metacognitive awareness inventory (Jr. MAI), and Schommer epistemological belief questionnaire (EB) were administered to students. Factor Analysis of Jr. MAI revealed both knowledge of cognition and regulation of cognition items were loaded into one factor. Confirmatory factor analysis of EB revealed a four factor structure namely innate ability, quick learning, omniscient authority, and certain knowledge. Regression analyses revealed that metacognition and omniscient authority were significant predictors of personal relevance dimension of CLES. Metacognition was found as the only predictor of the student negotiation. Innate ability and metacognition significantly contributed to uncertainty. This study revealed that the elementary students with different mastery levels hold different epistemological beliefs and multi-faceted nature of elementary school students’ metacognition was seemed to be supported with this study. It was found that metacognition contributed to model more than epistemological beliefs for all three dimensions of CLES.  相似文献   

Prior knowledge in mathematics and study success in engineering: informational value of learner data collected from a web-based pre-course     

Katja Derr  Reinhold Hübl  Mohammed Zaki Ahmed 《European Journal of Engineering Education》2018,43(6):911-926

The article describes the development and evaluation of a web-based pre-course in mathematics, delivered to four cohorts of engineering students at a German university. Based on demographic, personal, and learning-related data relationships between students’ preconditions, their learning gains in the pre-course, and study success in the degree programme were analysed. The results support the existing literature in that domain-related prior knowledge and secondary school achievement play a dominant role regarding study success in engineering. The analyses also showed that the influence of cognitive predictors could only be compensated for by a strong learner engagement. At-risk students with high pre-course learning gains showed significantly better first-year performance. The number of self-tests a student attempted was positively related to pre-course learning gains and even to first-year performance, suggesting that this variable is a good indicator of student engagement.  相似文献   

Possible Role of microRNA-122 in Modulating Multidrug Resistance of Hepatocellular Carcinoma     

Shaymaa M. M. Yahya  Shadia A. Fathy  Zakaria A. El-Khayat  Safinaz E. El-Toukhy  Ahmed R. Hamed  Marwa G. A. Hegazy  Heba K. Nabih 《Indian journal of clinical biochemistry : IJCB》2018,33(1):21-30

Hepatocellular carcinoma (HCC) is a hypervascular primary liver cancer characterized by rapid progression, besides, resistance to traditional chemotherapeutic agents. It has been shown that microRNAs play critical roles in regulation of tumor cell sensitivity to drugs through modulating the expression of genes involved in drug transport. The present study investigated whether restoration of miR-122 in HCC cells could alter the cell cycle distribution and the expression of multidrug resistance (MDR)-related genes (ABCB1, ABCC1, ABCG2 and ABCF2). After overexpression of miR-122 in HepG2 cells treated or untreated with doxorubicin doses, total RNAs and protein extracts were isolated for application of QRT-PCR and western blotting techniques. Moreover, cell cycle distribution was monitored by flow cytometry. Our results revealed that, the over expression of miR-122 in HepG2 cells treated or untreated with doxorubicin could modulate the sensitivity of cells to chemotherapeutic drug through downregulation of MDR-related genes, ABCB1 and ABCF2. Interpretation of cell cycle distribution revealed that, the anti-proliferative effect of miR-122 is associated with the accumulation of cells in G₀/G1 phase. Moreover, treatment with miR-122 and doxorubicin resulted in high percentage of HCC cells in G₀/G1 phase. Taken together, our findings revealed that, overexpression of miR-122 inhibited HCC cell growth by inducing cell cycle arrest and this arrest is associated with down-regulation of MDR-related genes.  相似文献
