The effectiveness of self-regulated learning scaffolds on academic performance in computer-based learning environments: a meta-analysis

This meta-analysis examined research on the effects of self-regulated learning scaffolds on academic performance in computer-based learning environments from 2004 to 2015. A total of 29 articles met inclusion criteria and were included in the final analysis with a total sample size of 2648 students. Moderator analyses were performed using a random effects model that focused on the three main areas of scaffold characteristics (including the mechanism, functions, delivery forms, mode, and number of scaffolds; how to promote self-regulated learning by scaffolds); demographics of the selected studies (including sample groups, sample size, learning domain, research settings, and types of computer-based learning environments); and research methodological features (including research methods, types of research design, types of organization for treatment, and duration of treatment). Findings revealed that self-regulated learning scaffolds in computer-based learning environments generally produced a significantly positive effect on academic performance (ES = 0.438). It is also suggested that both domain-general and domain-specific scaffolds can support the entire process of self-regulated learning since they demonstrated substantial effects on academic performance. Different impacts of various studies and their methodological features are presented and discussed.     

Multicultural Visions of Globalization: Constructing Educational Perspectives From the East and the West

The thesis of this essay is that globalization is a phenomenon that humankind must be educated for understanding as a process of global evolution. The new world evolving is being defined as requiring a new sense of collective cooperation amongst the peoples of the Earth, if we are to continue to exist on the planet. Educators are in the midst of and have an important role to play in this social and conscious evolution. One of our challenges is to explore the theoretical foundations for framing a new global education agenda. The assertion is that the theories of global, social, and conscious evolution of 20^th century intellectuals and visionaries such as India’s Sri Ghose Aurobindo (1872-1950) and France’s Pierre Teilhard de Chardin (1881-1955) provide the foundation from which to construct a new global educational perspective.     

Parents’ and Early Childhood Educators’ Attitudes and Practices in Relation to Children’s Outdoor Risky Play

This study contributes to the understanding of early childhood educators’ and parents’ attitudes and practices in relation to outdoor risky play for children. This study included 26 early childhood educators and 112 parents in rural and metropolitan areas of Australia and the United States. Participants completed an online survey about their perspectives and practices related to the provision of opportunities for children to engage in outdoor risky play. Questions also investigated reasons that prevented participants from providing such opportunities for children. Findings indicated that most educators thought it was important for children to be provided opportunities for outdoor risky play and did provide appropriate activities. Types of outdoor risky play opportunities fell into the categories of supporting large motor skills, supporting free exploration of the environment, and supporting assessment of risk. However, educators located in Australia rated outdoor risky play opportunities as significantly more important compared to educators in the US. Many parents also felt outdoor risky play was important and provided appropriate activities. Opportunities provided by parents fell into the same categories as educators, with additional features of nervousness and a desire to avoid hovering. Many parents identified the young age of the child and safety concerns as barriers. Implications for research and practice are discussed.     

The World Bank,support for universities,and asymmetrical power relations in international development

This article examines the role of the World Bank in advancing higher education sectors in the developing world, considering in particular the increasing power and strength of a global knowledge-based economy. Given the powerful role that intergovernmental organizations such as the World Bank play in shaping global economic policies, the authors are concerned about how the Bank’s policies and actions may limit knowledge generation and capacity building of universities in the developing world. Relatedly, the authors use case studies of the Bank’s involvement in Thailand and Uganda to better understand the role it plays in producing and reproducing forms of global hegemony. The authors discuss hegemony in terms of neocolonialism and neoliberalism. Neocolonialism is described as forms of domination advanced by powerful nations and their institutions, while neoliberalism is understood as an economic ideology by which weaker nations may be brought into greater alignment with global trade initiatives.     

对称三对角矩阵的QL方法论

QL(QR) method is an efficient method to find eigenvalues of a matrix. Especially we use QL(QR) method to find eigenvalues of a symmetric tridiagonal matrix. In this case it only costs O( n^2) flops, to find all eigenvalues. So it is one of the most efficient method for symmetric tridiagonal matrices. Many experts have researched it. Even the method is mature, it still has many problems need to be researched. We put forward five problems here. They are: (1) Convergence and convergence rate; (2) The convergence of diagonal elements; (3) Shift designed to produce the eigenvalues in monotone order; (4) QL algorithm with multi-shift; (5) Error bound. We intoduce our works on these problems, some of them were published and some are new.     

Higher education and the achievement (and/or prevention) of equity and social justice

The article examines the theoretical and empirical literature on higher education’s role in relation to social equity and related notions of citizenship, social justice, social cohesion and meritocracy. It considers both the education and the research functions of higher education and how these impact upon different sections of society, on who benefits and who loses from them. Questions for future research on the wider impact of higher education are posed as well as some research questions on the narrower issue of widening participation.
