'Intentional repetition' and learning style: Increasing efficient and cohesive interaction in asynchronous online discussions     

Abdullah Topçu 《British journal of educational technology : journal of the Council for Educational Technology》2008,39(5):901-919

This study verified the efficacy of the intentional repetition technique in improving interaction in asynchronous online discussions by taking into account the learning styles of the participants. A conceptual framework served for the development of the technique, which conceptualises efficient and cohesive interaction on a continuum of process that move from social presence to production of an artefact. Sixty-one university students participated in the study. A quasi-experimental research design was used. The subjects, who were assigned randomly into two groups, were tested using Kolb's learning style inventory. The results showed that the experimental group exposed to the intentional repetition technique produced significantly better interaction than the control group, regardless of their learning styles, which had no significant effect on the interaction. Moreover, there was no interaction effect between the learning styles and the treatment. The implications arising from these results identify various suggestions for increasing the coherence and depth of the interaction amongst students in asynchronous online discussions.  相似文献

Misconceptions About Human Rights and Women’s Rights in Islam     

Khalida Tanvir Syed 《Interchange》2008,39(2):245-257

This paper aims to clarify three current misconceptions about the Islamic faith and issues of human rights and women’s rights in the West. The first misconception is that Muslims are terrorists because they believe in Jihad. It is factually the case that Islamic teachings stress the value of peace and prosperity for all human beings. The second misconception is that Muslims prohibit scientific knowledge and only aim to seek religious knowledge. To the contrary, Qur’an emphasizes that the opportunity to seek all forms of knowledge is a human right and responsibility of all Muslims. The third misconception and perhaps, the most controversial, is that Islam oppresses women. In reality, Islam offers women the right to make their own choices in the areas of education, business, and property, to name a few. By sharing my own experiential narrative as a Muslim born woman and that of a Canadian women who converted to Islam, I can actually see the similarities between human rights in Islam and the United Nation’s Universal Declaration of Human Rights (1948).  相似文献

This study seeks to describe the teachers’ professional development activities in Bangladesh and explores the hypotheses about the relationship between teachers’ traditional professional development activities and school improvement. Data from a representative sample of City secondary schools from Bangladesh (n = 127) were gathered through questionnaires from 127 principals and 694 teachers. Hierarchical multiple regression analysis was used in this research. This study found significant impacts of some of teachers’ professional development activities on school improvement. Also found that the maximum school improvement can be achieved if schools put more emphasis on teachers’ collaboration, in-service training and classroom observation and less emphasis on individual action enquiry. The findings of this study provide important information for the policy makers, educational managers and especially for the headmasters and teachers concerned with the improvement of teachers’ quality in secondary schools of Bangladesh. This study adopts a concurrent approach of data collection and analysis.  相似文献   

Anisotropic alignments of hierarchical Li2SiO3/TiO2 @nano-C anode//LiMnPO4@nano-C cathode architectures for full-cell lithium-ion battery     

Hesham Khalifa  Sherif A El-Safty  Abdullah Reda  Mohamed A Shenashen  Alaa I Eid 《国家科学评论(英文版)》2020,7(5):863

We report on low-cost fabrication and high-energy density of full-cell lithium-ion battery (LIB) models. Super-hierarchical electrode architectures of Li₂SiO₃/TiO₂@nano-carbon anode (LSO.TO@nano-C) and high-voltage olivine LiMnPO₄@nano-carbon cathode (LMPO@nano-C) are designed for half- and full-system LIB-CR2032 coin cell models. On the basis of primary architecture-power-driven LIB geometrics, the structure keys including three-dimensional (3D) modeling superhierarchy, multiscale micro/nano architectures and anisotropic surface heterogeneity affect the buildup design of anode/cathode LIB electrodes. Such hierarchical electrode surface topologies enable continuous in-/out-flow rates and fast transport pathways of Li⁺-ions during charge/discharge cycles. The stacked layer configurations of pouch LIB-types lead to excellent charge/discharge rate, and energy density of 237.6 Wh kg⁻¹. As the most promising LIB-configurations, the high specific energy density of hierarchical pouch battery systems may improve energy storage for long-driving range of electric vehicles. Indeed, the anisotropic alignments of hierarchical electrode architectures in the large-scale LIBs provide proof of excellent capacity storage and outstanding durability and cyclability. The full-system LIB-CR2032 coin cell models maintain high specific capacity of ∼89.8% within a long-term life period of 2000 cycles, and average Coulombic efficiency of 99.8% at 1C rate for future configuration of LIB manufacturing and commercialization challenges.  相似文献   

Online activities of urban Malaysian adolescents: report of a pilot study     

Kok Eng Tan  Melissa Ng Lee Yen Abdullah  Kim Guan Saw 《Literacy》2012,46(1):33-39

The literacy practices of many communities today show new ways of meaning making in the contemporary, technological and digital culture. A number of Malaysian adolescents belong to this culture. This pilot study reports the preliminary findings of a larger study aimed at describing the online activities of Malaysian adolescents. Fifty‐four participants from an urban secondary school in Penang took part in this study. One finding showed that the percentages of language use on the Internet were: 80.6 per cent in English, 10.6 per cent in Bahasa Malaysia and 8.8 per cent in Chinese. In addition, the study also revealed some common websites that these adolescents frequented. The findings point to the need to investigate the extent of these online literacy practices beyond school among the adolescent population in Malaysia and to look into the implications for ESL education.  相似文献

Adriana J. Uma?a‐Taylor  Stephen M. Quintana  Richard M. Lee  William E. Cross Jr.  Deborah Rivas‐Drake  Seth J. Schwartz  Moin Syed  Tiffany Yip  Eleanor Seaton  Ethnic  Racial Identity in the st Century Study Group 《Child development》2014,85(1):21-39

Although ethnic and racial identity (ERI) are central to the normative development of youth of color, there have been few efforts to bring scholars together to discuss the theoretical complexities of these constructs and provide a synthesis of existing work. The Ethnic and Racial Identity in the 21st Century Study Group was assembled for this purpose. This article provides an overview of the interface of ERI with developmental and contextual issues across development, with an emphasis on adolescence and young adulthood. It proposes a metaconstruct to capture experiences that reflect both individuals’ ethnic background and their racialized experiences in a specific sociohistorical context. Finally, it presents milestones in the development of ERI across developmental periods.  相似文献   

The Effectiveness of Interacting with Scientific Animations in Chemistry Using Mobile Devices on Grade 12 Students’ Spatial Ability and Scientific Reasoning Skills     

Sulaiman M. Al-Balushi  Ali S. Al-Musawi  Abdullah K. Ambusaidi  Fatemah H. Al-Hajri 《Journal of Science Education and Technology》2017,26(1):70-81

The purpose of the current study was to investigate the effectiveness of interacting with animations using mobile devices on grade 12 students’ spatial and reasoning abilities. The study took place in a grade 12 context in Oman. A quasi-experimental design was used with an experimental group of 32 students and a control group of 28 students. The experimental group studied chemistry using mobile tablets that had a digital instructional package with different animation and simulations. There was one tablet per student. A spatial ability test and a scientific reasoning test were administered to both groups prior and after the study, which lasted for 9 weeks. The findings showed that there were significant statistical differences between the two groups in terms of spatial ability in favour of the experimental group. However, there were no differences between the two groups in terms of reasoning ability. The authors reasoned that the types of animations and simulations used in the current study featured a wide range of three-dimensional animated illustrations at the particulate level of matter. Most probably, this decreased the level of abstractness that usually accompanies chemical entities and phenomena and helped the students to visualize the interactions between submicroscopic entities spatially. Further research is needed to decide on types of scientific animations that could help students improve their scientific reasoning.  相似文献
