International Initiatives of the Virtual University and Other Forms of Distance Learning: The Case of the African Virtual University

The African Virtual University (AVU) is attempting to address the huge and unmet demand for educational services in Africa and presents the experiences, lessons, and adjustments being made to achieve improved effectiveness and relevance. This university seeks to address these issues by harnessing the power of modern information and communications technologies (ICTs) to provide cost-effective education and training. AVU is the only institution offering technology-based distance education for the whole continent and has a first-mover advantage. The intervention of the African Virtual University will result in increased access to quality education, improve access to quality literature internationally, and enhance interaction among African academics and between them and the rest of the world.     

Participants’ views of the potential of international youth football tournaments for development in the Global South

This paper investigates the potential of international youth football tournaments for youth development in the Global South. The tournaments under study were East Africa Cup in Tanzania, and Norway Cup in Norway. Through qualitative interviews with tournament participants, we addressed the following research question: What are the participant’s views of the potentials of Norway Cup and East Africa Cup in dealing with development issues facing youth in the Global South? Our findings demonstrate that all interviewees consider the tournaments potentially beneficial for youth development in the Global South. In the analysis, we identified four different categories, mostly representing positive outcomes of tournament participation. We argue that a functionalist neo-liberal notion of sport is visible in the data material. Thus, our findings correspond with Sport for Development and Peace (SDP) research showing how reproductions of the SDP functionalist discourse ‘continue to be leveraged through sport and sealed into the success story of SDP’.     

Designing distance learning programmes for Limited English Proficient (LEP) students in large urban areas: An application of perceptual mapping and conjoint analysis methods

Providing low cost, high quality educational services to growing numbers of multilingual communities is perhaps one of the greatest challenges facing large urban school districts. In the Los Angeles urban area, adult students who wish to attend English as a Second Language (ESL) classes are presently constrained by the limitations of school resources, public transportation and growing levels of crime and street violence. Urban distance learning programmes may provide the best alternative to meet the educational needs of Limited English Proficient (LEP) adult students because it can service large numbers of students who are separated from their schools by geographical distance, safety, convenience, transportation, etc. Using perceptual mapping and conjoint analysis methodologies, this study analytically identifies and examines the design features or attribute characteristics of an ESL urban distance learning programme for LEP adults. Using focus groups as the basis to identify these attributes, perceptual mapping methods point to a market niche in developing technology‐driven, low‐cost distance learning programmes for these students. A conjoint analysis survey finds that LEP students generally favour distance learning programmes where ‘cost’, ‘effectiveness’ and ‘assessment’ are the primary attribute components.     

Use of Plastic Correction Formula to Improve Accuracy of Welding Residual Stress Test with Blind-Hole Method

The blind-hole method is the most widely used approach to experimentally determine the distribution of residual stress. This paper aims to improve test accuracy of welding residual stress and conducts an experimental study on the strain release factors involved when using the blind-hole method for Q235 and Q345, two steels commonly used in building structures. The ranges of strain release factors A and B in the elastic stage, the effects of strain release factors on residual stress calculated values, and the plastic corrected strain release factors are analyzed considering of the effect of plastic deformation around the blind hole on measurement accuracy. Finally, a simplified calculation formula to determine strain release factors is proposed for use with the blind-hole method. Results show that in the elastic stage, strain release factor A for Q235 and Q345 ranges from-0.399 to-0.525 and strain release factor B from-0.791 to-0.960. Changing the strain release factors A and B shows that calculated residual tensile stress varies in relation to a decrease in both factor values. However, there is a increase in calculated residual compressive stress with a decrease in the strain release factor A value, but there is an decrease with a decrease in strain release factor B value. Calculated residual stress applied to elastic strain release factors is compared with that applied to amended plastic strain release factors for Q235 steel. The maximum deviation between calculated residual stress and test stress is reduced from 21.1 to 1.0%,and for Q345 steel from 26.5 to 1.2%. It is thus evident that the plastic correction formula proposed in this paper can be used in calculations when conducting a residual stress test.     

The issue of the arrangement of new environments for science education through collaborative actions between schools,museums and science centres in the Brazilian context of teacher training

We present, in this article, an investigation about the potential of the relationship between formal and non-formal educational environments. Therefore it is not an empirical research, but an essay on the topic. This paper demonstrates the concept that science education and science outreach can be privileged by actions that are developed by closer relations between formal and non-formal places. Currently, non-formal environments such as museums and science and technology centres are considered potential educational resources within the reach of schools. Educators from museums have conducted studies which demonstrate a predominant model of the utilization of these institutions by teachers, which consists of illustrative visits during the exhibitions, but does not feature a collaborative relationship or partnership between schools and these institutions. In Brazil, the main examples of approaches to collaboration between these places and schools have been taking place through the initiatives of teachers or through projects developed by the educational sector, aiming to broaden the dialogue between their institutions and the school community. Another approach mechanism relates to research and extension projects developed by university researchers, sponsored by state and federal funding agencies. In this case, the universities and university museums appear as new social actors that stand in the way of the schools and the cultural environments, complicating the relationship and, at the same time, bringing new questions to the field of educational research. We believe that the discourse in this paper should bring about further discussions in the initial teacher training courses to contribute to the understanding of practices related to the extension of the field of activity of the school.

Vibration Analysis of a Rectangular Plate

Presented herein is a detailed analysis of the small, free oscillations of pre- stressed rectangular plates in both pre- and post-buckling ranges. The simply supported plate is stressed either thermally or by the uniaxial in-plane loads on two opposite edges, the other two edges are taken to be either freely movable or immovable, and all the edges are restrained to remain straight. Both the symmetrical and anti-symmetrical small vibration modes superimposed upon both primary- and secondary-buckling, and the coupling among these modes, are studied. A criterion for the existence of coupling is given. Some numerical results are then presented.     

Context matters: increasing understanding with interactive Clicker Case studies

Although interactive technology is presumed to increase student understanding in large classes, no previous research studies have empirically explored the effects of Clicker Cases on students?? performance. A Clicker Case is a story (e.g., a problem someone is facing) that uses clickers (student response systems) to engage students in understanding the meaning of the science contained within the story. Using an experimental randomized Solomon design across 11 institutions, we found that Clicker Cases increased student understanding more than PowerPoint lectures in large introductory biology classrooms, although there was variation across institutions and topics. By examining student performance in conjunction with faculty experience, we found that strong Clicker Cases created dissonance, captured attention and involved students in interpreting data or making decisions. This study provides a model for collaborative research across multiple institutions and demonstrates the need for using multiple institutions and topics in research on education.     

Examining the Relationship Between Neighborhood Environment and School Readiness for Kindergarten Children

In the current research project, the relationship between neighborhood environment and school readiness was investigated. To measure neighbourhood environment, data from the 2001 Canadian Census were used, while school readiness was measured using the Early Development Instrument (EDI). EDI data were collected for kindergarten children across British Columbia, Canada, in the school years 2000/2001 through 2004/2005 by the Human Early Learning Partnership. A hierarchical linear modeling approach to data analysis was taken given the complex structure of the data (children nested within neighborhoods). Results from this study suggest that neighborhood environment is related to children's school readiness outcomes as measured by the EDI. Specifically, all 5 EDI domains were significantly predicted by between 2 and 8 of 13 neighborhood variables that were conceptually grouped into 8 categories accounting for family structure, income, education, Aboriginal status, language, labor force occupations, employment rates, and domestic work. Overall, 3 themes emerged from this study that suggest neighborhood-level sources of social wealth: the importance of neighborhood culture, stability, and heterogeneity in promoting better school readiness outcomes for children. Formulations regarding areas for future research are presented.
