Teaching for understanding in science: constructivist / conceptual change teaching approaches

This two-paper set has arisen from a concern within the Victorian Science in Schools Research Project, to help teachers support student learning of science content. In the first paper, the research on student learning of science conceptions was reviewed, and the major findings presented. It traced the changing ways we have viewed science teaching and learning, over the last two decades. This second paper looks at a variety of teaching schemes that aim to support meaningful learning in science, some based on the metaphor of conceptual change, and draws out principles from these for how we might best support student learning of major science ideas.

Exploring metaphor as an alternative marketing language

Purpose: – The main aim of this paper is to stimulate more relevant and critical ideas about marketing and the wider management field by exploring the actual and potential contribution of metaphor to marketing theory and practice. The subsequent connections made can help contribute towards understanding and coping with the theory/practice gap.

Design/methodology/approach: – To date, the majority of metaphor application has tended to be literal and surface-level rather than theoretically grounded. This paper interrogates the literature surrounding metaphor in marketing and management fields, while also examining the contribution of other areas such as art. The paper constructs and debates the conceptual notion of the marketer as an artist.

Findings: – Incorporation of theoretically grounded metaphors into marketing theory can help develop a form of marketing which is capable of dealing with ambiguity, chaotic market conditions, creative thinking and practice.

Originality/value: – Adoption of a metaphorical approach to marketing research helps to instil a critical and creative ethos in the research process. Marketers are concerned with identification and exploitation of opportunities. Metaphor assists in the process by enhancing visualisation of these future directions. We live out our lives to a large degree through the making of metaphorical connections. We should therefore embrace more qualitative, creative associations in marketing theory, as well as practice.

Financial safety nets: reconstructing and modelling a policymaking metaphor

This paper explains that financial safety nets exist because of difficulties in enforcing contracts and shows that elements of deposit-insurance schemes differ substantially across countries. It shows that differences in the design of financial safety nets correlate significantly with differences in the informational and contracting environments of individual countries and that a country's GDP per capita is correlated with proxies for a country's level of: (1) informational transparency, (2) contract enforcement and deterrent rights, and (3) accountability for safety net officials. The analysis portrays deposit insurance as a part of a country's larger safety net and contracting environment. This means that there is no universal method for preventing and resolving banking problems and that the structure of a country's safety net should evolve over time with changes in private and government regulators' capacity for valuing financial institutions, disciplining risk taking and resolving insolvency promptly, and for being held accountable for how well they perform these tasks.

Football-as-war, coach-as-general: analogy, metaphor and management implications

Sporting terms have been used as metaphor and analogy to describe and prescribe life experiences. It has been suggested that the use of sport terminology can assist in the general understanding of complex terms and situations, however, the use of sport as metaphor and analogy for many aspects of social understanding can have negative consequences. The analogy of sport and war seems to be particularly prevalent within football, irrespective of the code or culture in which it is played. This article demonstrates the popular understanding of Australian Rules ‘football as war’ through two complementary studies. The first study investigates the representation of Australian Rules football as war, specifically through the analysis of both images and text on the front covers of the sport ‘lift-out’ sections of two prominent Melbourne newspapers, The Herald Sun and The Age. The second study examines whether people interpret non-war-like images of Australian Rules football in war-like terms. Forty-five undergraduate sport marketing and management students were asked to write about one of four different images of football players and coaches interacting, which revealed that football is understood as war. Further, when prompted by an image of football players and coaches interacting, people in this study interpreted the interactions as consistently war-like. Coaches were portrayed as militaristic generals and the athletes as soldiers. Implications for management, education and practice are discussed.

A conceptual model for sport services marketing research : integrating quality, value and satisfaction

This paper advances our understanding of the relationship between quality, value and satisfaction in the context of spectator sport services. This is achieved through an analysis and examination of relevant secondary data culminating in a conceptual model Although extensive research has been conducted in the three separate areas of quality, value and satisfaction, to date no work has been reported attempting to develop macro models that capture the concepts and their potential interrelationships. Such macro models could enhance the communication and stimulate further research for sport marketing scholars. This paper proposes a model apposite for further research and in the process leads to the potential confirmation, rejection or, indeed, adaptation of the conceplualization of sport services.

Constructivism in environmental education: beyond conceptual change theory

Abstract constructivism, as a set of theories about how learners learn, has been an important discourse in the educational research literature for a number of years. Interestingly, it has been far more visible in science education research than in environmental education research. This article considers conceptual change theory within constructivism as a contested concept, outlines differing expressions of constructivism in science education and environmental education, and argues for approaches to environmental education that adopt socially constructivist perspectives with respect to the character of the subject matter content as well as to learners' apprehension of such content. In considering implications for research, this perspective is juxtaposed with a recent United States Education Act, which prescribes a far more objectivist approach to educational research and which serves as a reminder that research itself is a powerful factor in shaping how the nature of subject matter is constructed, learning and the implications of these for teaching practice.

Exploration of Year 10 students' conceptual change during instruction

This article reports on a classroom-based case study of a group of six Year 10 students, within a class of 23 students. The study implemented constructivist-informed teaching and learning approaches within a classroom setting in the topic of optics and documented any changes in the conceptual understanding students had about seven central concepts of geometrical optics over a teaching sequence lasting nine weeks.

Methodological and conceptual issues in the search for a relationship between animal body-size distributions and benthic habitat architecture

Benthic ecologists have studied the distribution of animal body sizes because it is a form of ‘taxon-free’ classification that may be a useful metric for describing variation within and between ecological communities. In particular, the idea that the allometry of physiological and life-history traits may control species composition and relative abundances implies a functional link between body-size distributions and communities. The physical structure of aquatic habitats has often been cited as the mechanism by which habitat may determine body-size distributions in communities. However, further progress is hindered by a lack of theoretical clarity regarding the mechanisms that connect body size to the characteristics of ecological communities, leading to methods that may obscure interesting trends in body-size data. This review examines the methodological and conceptual issues hindering progress in the search for a relationship between animal body size and habitat architecture and suggests ways to resolve these issues. Problems are identified with current methods for the measurement of animal body size, the data and measures used to quantify body-size distributions and the methods used to identify patterns therein. Fundamentally, renewed emphasis on the mechanisms by which animal body sizes are influenced by habitat architecture is required to refine methodology and synthesise results from pattern-seeking and mechanistic studies.

A conceptual model for recruitment and retention : allied health workforce enhancement in Western Victoria, Australia

Attracting and retaining allied health professionals in rural areas is a recognised problem in both Australia and overseas. Predicted increases in health needs will require strategic actions to enhance the rural workforce and its ability to deliver the required services. A range of factors in different domains has been associated with recruitment and retention in the allied health workforce. For example, factors can be related to the nature of the work, the personal needs, or the way an organisation is led. Some factors cannot be changed (eg geographical location of extended family) whereas others can be influenced (eg education, support, management styles). Recruitment and retention of allied health professionals is a challenging problem that deserves attention in all domains and preparedness to actively change established work practices, both individually as well as collectively, in order to cater for current and predicted health needs. Changes to enhance workforce outcomes can be implemented and evaluated using a cyclic model. The Allied Health Workforce Enhancement Project of the Greater Green Triangle University Department of Rural Health (GGT UDRH) is working towards increasing the number of allied health professionals in the south west of Victoria. Based on themes identified in the literature, an interactive model is being developed that addresses recruitment and retention factors in three domains: (1) personal or individual; (2) organisation; and (3) community.

Paediatric quality of life instruments: a review of the impact of the conceptual framework on outcomes

With an increasing number of paediatric quality of life (QOL) instruments being developed, it is becoming difficult for researchers and clinicians to select the most appropriate instrument. Reviews of QOL instruments tend to report only basic properties of the instruments such as domains and psychometric properties. This paper seeks to appraise critically the conceptual underpinnings of paediatric QOL instruments. A systematic review was conducted to identify QOL instruments for children aged 0 to 12 years, and to examine and compare their conceptual frameworks, definitions employed, and structure. Both generic and condition-specific measures were reviewed. Fourteen generic and 25 condition-specific QOL instruments were identified. Eleven types of definition of QOL and health-related QOL and three theories of QOL were identified. QOL was measured by a variety of domains including emotional, social and physical health, and well-being. Items commonly assessed difficulties, or intensity/frequency of feelings/symptoms, in contrast to positive aspects of life and happiness. The findings highlight the diversity that is apparent in the conceptualization of paediatric QOL and draw attention to the lack of empirical evidence for many of the fundamental assumptions. The impact of the conceptual underpinnings of the instruments on the resulting QOL scores is discussed.

Penetration testing professional ethics : a conceptual model and taxonomy

In an environment where commercial software is continually patched to correct security flaws, penetration testing can provide organisations with a realistic assessment of their security posture. Penetration testing uses the same principles as criminal hackers to penetrate corporate networks and thereby verify the presence of software vulnerabilities. Network administrators can use the results of a penetration test to correct flaws and improve overall security. The use of hacking techniques, however, raises several ethical questions that centre on the integrity of the tester to maintain professional distance and uphold the profession. This paper discusses the ethics of penetration testing and presents our conceptual model and revised taxonomy.

Consumer complaint actions: a conceptual model based on complainants about advertising in Australia

This article presents a new conceptual model detailing consumer complaint responses relating to exposure to unacceptable advertising. The model is initiated by consumer perceptions of negative inequity which elicits one of three consumer complaint responses based on the identified triggers that may influence complaining propensity such as demographic, psychographic, cultural, situational and social factors. Complainant perception of the process encountered together with the overall outcome of their experience affect future complaint behaviour as shown by this evolving model as the end reaction flows on to form the consumer’s next response to a similar situation. The advertising industry in Australia is valued annually at over $8 billion and some advertisements have been identified as ‘unacceptable’ by elements in society. Industry and regulatory response to consumer complaints is thus an important area to address and there is no extant literature utilising such an holistic model.
