What is a virtual world? Definition and classification

In 2008, articles by Bell and Schroeder provided an initial platform from which to develop a coherent definition of the term ‘virtual worlds’. Yet over the past ten years, there has been little development of the term. Instead there is confusion in the literature, with the introduction of new terms which are at times used to classify the type of virtual world and at others are used synonymously with the term. At the same time there has been a resurgence of interest in the potential of virtual reality which further muddies the conceptual waters. While the lack of a clear and common understanding of a term is not uncommon, there are implications for researchers and practitioners. To address these issues, this paper presents a new framework for the definition of virtual worlds, arguing what it is for a world to be virtual, the user experience that is a necessary part of this and the technical features which afford this. For the first time the relationships between commonly confused terms and technologies are identified to provide a much needed conceptual clarity for researchers and educators.

What is shared? A framework for understanding shared innovation within communities

The twenty-first century economy often requires the innovative production of conceptual and physical artifacts. These innovations frequently are developed collaboratively within communities of workers. Previous theories about the nature of work and learning within communities have emphasized shared meaning or shared practice, but now shared innovation is required. In this paper, I describe the development of a model for conceptualizing and studying shared innovation within communities. This model was created from merging elements of social learning and creativity/innovation theories. I explain that at an intersection of these two domains is a unique kind of social structure, called a Community of Innovation, or COI. I conclude by describing the characteristics of a COI and its implications for design and research.

What is Wrong with Using Textbooks in Education?

In this article, it is argued that the inordinate amount of time and attention given to the use of textbooks in education inadvertently leads to deadening miseducative experiences and creates a learning environment where what Dewey calls ‘consummatory experience’ is thwarted. In order to unpack this thesis, Dewey’s pragmatist aesthetics is engaged, and in particular, his concept of consummatory experience is defined and its temporal nature is elucidated by referring to two modes of time: chronological and phenomenological. Subsequently, the relation between teaching and consummatory experience is elucidated to uncover the reason why using textbooks is counterproductive.     

What is ‘Natural’ in Natural Selection?

To understand Darwin’s concept of natural selection, we have to contrast it with his characterization of artificial selection, and then ask: what is natural in natural selection? While we do this, we develop two distinctions: one between ‘change by transformative action’ and ‘change by selection’, and another between ‘artificial selection’ and ‘natural selection’. The first distinction helps us understand evolution by selection and the second natural selection.     

What is behind the decline in student achievement in Australia?

Australian school student achievement in reading and mathematical literacy has fallen in the Programme for International Student Assessment (PISA) collection since 2000. This study finds that these declines were widespread in the student population, affecting both males and females. However, the decline in reading literacy occurred throughout much of the achievement distribution, while the decline in mathematical literacy was more pronounced at the top of the distribution (there were fewer high performing students in 2009 compared with 2003). Declines in both literacy domains were apparent across the entire distribution of schools, however, the falls in school performance were more apparent in private schools than in the government-run school systems in Australia. The declines were not associated with many other characteristics of schools, including many factors that might have been thought to be associated with school performance.
