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.     

Risk and Adversity,Parenting Quality,and Children's Social-Emotional Adjustment in Families Experiencing Homelessness

A multimethod, multi-informant design was used to examine links among sociodemographic risk, family adversity, parenting quality, and child adjustment in families experiencing homelessness. Participants were 245 homeless parents (M_age = 31.0, 63.6% African American) and their 4- to 6-year-old children (48.6% male). Path analyses revealed unique associations by risk domain: Higher sociodemographic risk predicted more externalizing behavior and poorer teacher–child relationships, whereas higher family adversity predicted more internalizing behavior. Parenting quality was positively associated with peer acceptance and buffered effects of family adversity on internalizing symptoms, consistent with a protective effect. Parenting quality was associated with lower externalizing behavior only when sociodemographic risk was below the sample mean. Implications for research and practice are discussed.     

USING CHILDREN'S WORK TO REFLECT ON TEACHING: ONE EARLY CHILDHOOD STUDENT TEACHER'S REFLECTIONS

Abstract

The purpose of the study was to examine the engagement of preservice teachers in the kind of authentic experiences that provided the modeling needed to make high‐quality instruction in mathematics a reality for young children. Inasmuch as these preservice teachers had not yet received any formal methods classes in mathematics, the authors theorized that classroom teachers whose practices and dispositions were congruent with the National Council of Teachers of Mathematics standards and the State of South Carolina Mathematics Standards could model effective teaching instruction for young children using the project approach. These same teachers could then provide mentoring and encouragement to preservice teachers as they became involved in this high‐quality program for 4‐year olds, deepening the knowledge base of the preservice teachers regarding developmentally appropriate ways to teach numeracy to 4‐year olds. © 2005 Elsevier Inc.

Validation of the Olympic Games Attitude Scale (OGAS): Evidence from Exploratory and Confirmatory Factor Analyses

There have been extensive studies of local residents’ perception and reaction to the impacts of mega events. However, there is limited empirical research on the social impacts that shape foreign attitudes toward the host country. The purpose of this study was to develop and validate the Olympic Games Attitude Scale (OGAS) to examine viewers’ perception of the Olympics hosting country. Participants (N = 483) were based on a convenience sample in a local community of the mid-Atlantic region in the United States. Results of the exploratory factor analysis identified four factors (economic advancement, image enhancement, community enrichment, and turmoil development) with a total variance of 67.59%. Confirmatory factor analysis showed that after removing one item, the 13-item OGAS provided a good fit to the data (comparative fit index [CFI] = .97; incremental fit index [IFI] = .97, standardized root mean square residual [SRMR] = .049; root mean square error of approximation [RMSEA] = .080). It is concluded that the OGAS is a valid measuring instrument for assessing viewers’ perception of hosting the Olympic Games.     

Prospects for learning in river management: exploring the initial implementation of the Water Framework Directive in a Swedish river basin

This case study explores the initial implementation of the EU Water Framework Directive (WFD) in the Lule River basin, Sweden, examining how and to what extent administrative procedures enable learning through dialogue and stakeholder collaboration. Theorising on adaptive co-management and social learning is used to structure what is to be learnt, how and by whom. Qualitative content analyses of policy documents, responses from consultation procedures and interviews show that there are opportunities for stakeholder involvement and dialogue in organizational settings of various kinds, but as the number of affected interest is large and difficult to demarcate many interests lack a formal channel for influence. It is primarily through poorly attended Water Council meetings and during the consultation process prior to decisions on management plans that all affected interests can voice their opinions. Consultation processes represent one-way communication rather than dialogue and the ones examined are strongly focused on scientific rather than experience based knowledge. If language is to be used productively to assist the constitution of relevant knowledge in the implementation of the WFD, it is important to find ways of communication that can serve as a platform for common meaning making among a large number of diverse societal actors.     

Welche Rolle spielt neben Merkmalen des Instruktionsdesigns die fachspezifische und aufgabenspezifische Motivation beim Lernen mit Multimedia im naturwissenschaftlichen Unterricht?

The present paper reports on an empirical study which investigated learning with text and animations in the science classroom. In a 2?×?2 design the presence of multimedia learning material instruction (text only vs. text + animations) as well as the modality of the explanatory text (spoken vs. written) were tested. Prior to learning, students’ motivation to learn was assessed as a continuous factor. Recall and transfer were assessed immediately after learning. The results show better recall of information for learners with multimedia materials, providing the animations were accompanied by spoken text. However, in contrast to the positive effects of domain-specific motivation this multimedia effect was not evident for transfer. The effects of multimedia design were independent of motivation. Implications for future studies are discussed.     

Evaluation of the Learning to Teach for Social Justice–Beliefs Scale in an Australian context

A concern for social justice pervades the espoused curriculum of many pre-service teaching programmes, but the extent to which that curriculum influences the beliefs students hold is an open question. With the goal of developing an instrument suitable for evaluating such beliefs at the degree programme level, the present study analysed responses to the Learning to Teach for Social Justice–Beliefs (LTSJ–B) Scale (Enterline, S., Cochran-Smith, M., Ludlow, J.H., & Mitescu, E. (2008). Learning to teach for social justice: Measuring change in the beliefs of teacher candidates. The New Educator, 4, 267–290. doi:10.1080/15476880802430361) from 304 Australian pre-service teachers. Exploratory factor analysis and Rasch analysis both indicated a two-factor structure, driven by a methodological artefact of item valence. We conclude from these findings that a short, five-item version of the LTSJ–B Scale would suitably balance psychometric and pragmatic considerations, in the broader context of working within an institutionally aligned system of teaching evaluation with multiple levels.
