Design-Based Intervention Research as the Science of the Doubly Artificial

This article uses a variety of principles of cultural-historical activity theory to extend Herbert Simon’s (1996) insight into the inherent linkage between the creation of artifacts and design. We argue that design research must grapple with the doubly artificial, as the classrooms in which many educational designs are implemented are themselves already artificial and contingent—the products of design—and the learning that is the focus of investigation is already an adaptation to the classroom environment and so artificial. Focusing our discussion on the mesogenetic character of the temporal characteristics of typical educational design-based intervention research, we present an example of an 18-year-long life span of an intervention that was initially expected to last 3 or 4 years. Crises late in the life of the system, 1 of which rescued the system, 1 of which terminated it, documented through field notes written by undergraduate participants, provide evidence for the dynamics of the system’s internal functioning in relation to events occurring in the larger ecology of which it was a part.     

Promoting environmentally sustainable attitudes and behaviour through free‐choice learning experiences: what is the state of the game?

Environmental education, both in and outside of the classroom, aims to facilitate adoption of sustainable practice by both school students and the general public. This paper explores the role of free‐choice learning experiences in this regard. An overview of theoretical approaches underpinning free‐choice learning research is provided, examples are presented of the ways in which informal educational settings can promote environmentally sustainable attitudes and behaviour, and the factors contributing to the effectiveness of these endeavours are discussed. By reviewing research evidence in relation to these issues, the paper identifies the current ‘state of the game’ and areas where new research is needed.     

Motivational Factors and the Visitor Experience: A Comparison of Three Sites

Museums, art galleries, botanical gardens, national parks, science centers, zoos, aquaria and historic sites are important public learning institutions. The free‐choice learning offered in these settings is closely linked to visitors' intrinsic motivation, making it important to understand the motivational factors that impact on visitors' experiences. This paper presents data from a questionnaire administered to visitors at three sites: a museum, an art gallery, and an aquarium. Similarities and differences among the sites are reported in relation to visitors' expectations, perceptions of learning opportunities, engagement in motivated learning behaviors, and perceptions of the learning experience. The importance of learning to museum visitors and the unique opportunities and challenges of the museum in relation to other educational leisure settings are discussed. The authors argue that the study of motivational factors might contribute to the development of a common theoretical foundation for interpretation in museums and other informal learning settings.     

Introducing a fifth pedagogy: experience‐based strategies for facilitating learning in natural environments

Educators have identified four categories of ‘productive pedagogies’ that are considered to lead to authentic student engagement and learning in the classroom. This study was designed to explore and extend these pedagogies in the context of learning in natural environments, in particular, through the programmes of Queensland environmental education centres. In‐depth interview and observation data were collected from students, classroom teachers and centre teachers who had participated in 12 environmental education programmes across Queensland, in order to identify the strategies that are most effective in facilitating learning in the natural environment. A fifth productive pedagogy category, ‘experience‐based learning’, is proposed. Experience‐based learning is particularly important in addressing students’ environmental attitudes and actions. The implications for the delivery of environmental education programmes both within and outside the classroom are discussed.     

Beyond Learning: Exploring Visitors' Perceptions of the Value and Benefits of Museum Experiences

Abstract This paper explores the beneficial outcomes that visitors seek and obtain from a museum visit, in terms that are not related to learning outcomes. It uses a deductive qualitative approach to investigate the meaning and value of a museum visit from the visitors' perspective. Three different levels of the meaning of the experience are considered: the attributes of the setting that visitors value; the experiences they engage in; and the benefits they derive. The findings confirm the importance of the “satisfying experiences” framework for understanding visitor experiences in museums, and extend this understanding in relation to the beneficial outcomes these experiences produce. The study also highlights the importance of “restoration” as an outcome of a museum visit. It is argued that the concept of the museum as a restorative environment, which enables visitors to relax and recover from the stresses of life, is worthy of further research attention. These insights will enable museum practitioners to better understand and meet their visitors' multiple needs and expectations.     

Penguin Promises: encouraging aquarium visitors to take conservation action

This study investigates the impact of an innovative conservation action campaign called Penguin Promises implemented at uShaka Sea World in Durban, South Africa. Communication tools included interpretive signage, exhibits with and without animals, presentations, and personal interactions, along with a specially designed postcard, on which visitors could write a promise (pledge) to make a change in their daily lives to become more environmentally responsible. Visitors who completed a card were contacted a year or more after their visit and asked about the outcomes of their promise. The results (N = 316) showed that 49.4% of respondents could give an example of something positive they had done for the environment, that they attributed to the campaign. Based on the study, recommendations are provided for the design of effective visitor conservation action campaigns.     

Oxidants,antioxidant nutrients and the athlete

Strenuous physical exercise induces oxidative stress. There may be a number of sources of this oxidative stress, including mitochondrial superoxide production, ischaemia-reperfusion mechanisms and auto-oxidation of catecholamines. Severe or prolonged exercise can overwhelm antioxidant defences, which include vitamins E and C and thiol antioxidants, which are interlinked in an antioxidant network, as well as antioxidant enzymes. Evidence for oxidative stress and damage during exercise comes from direct measurement of free radicals, from measurement of damage to lipids and DNA, and from measurement of antioxidant redox status, especially glutathione. There is little evidence that antioxidant supplementation can improve performance, but a large body of work suggests that bolstering antioxidant defences may ameliorate exercise-induced damage, suggesting that the benefits of antioxidant intervention may be for the long term rather than the short term.     

Police Media: The Governance of Territory,Speed, and Communication

The work of the modern police apparatus is highly dependent upon media technologies. This article traces crucial developments in this history, analyzing the central role that media have played in policing practices since the advent of the modern patrol in the late eighteenth century. We trace how the governmentalized police force has used media to govern efficiently what Foucault calls the three great variables: territory, speed, and communication. In conclusion, we consider the possibilities for resistance in a time when digital police media have given rise to alarming strategies for surveilling populations, stifling dissent, and exerting control over public and private space.     

Assessing the Concerns and Professional Development Requirements of Beginning Teachers in their First Term of Teaching

Beginning teachers in Queensland Catholic primary schools were surveyed before, during and after their first term of full‐time teaching practice in order to identify predominant concerns and professional‐development needs. Anticipatory concerns about personal adequacy dissipated quickly after teaching began, allowing concerns over student‐learning needs and class control to emerge. By the end of the first term, teachers were beginning to feel more confident and relaxed in their role. Most had maintained a preference for discovery/inquiry methods of teaching although issues such as students’ classroom behaviour, the availability of teaching resources and time pressures were beginning to exert an influence on their choice of teaching styles. The results are interpreted in the context of beginning teacher induction programmes, and recommendations are made regarding areas in which beginning teachers need particular assistance during their first teaching term.
