Causal relationships of sport and exercise involvement with goal orientations,perceived competence and intrinsic motivation in physical education: A longitudinal study

Abstract

Little information exists about the causal relationships of sport and exercise participation with goal orientations, perceived athletic competence and intrinsic motivation in physical education. A longitudinal study was conducted involving 882 Greek students who completed questionnaires on three occasions: 3 – 5 weeks into the academic year, 3 – 6 weeks before the end of the academic year, and 7 months later. The data were analysed using structural equation models, controlling for age. Task orientation and intrinsic motivation in physical education at the beginning of the academic year predicted sport and exercise participation 7 and 14 months later. Perceived athletic competence both at the beginning and end of the academic year predicted sport and exercise participation 7 and 14 months later, while ego orientation did not predict sport and exercise involvement at either time. Previous sport and exercise participation had positive effects on task orientation and perceived athletic competence 3 – 6 weeks before the end of the academic year and predicted all cognitive-affective constructs 7 months later. These results imply that the cultivation of task orientation, intrinsic motivation in physical education and perceived athletic competence will help to promote sport and exercise participation in adolescence.

Fostering a Sense of Wonder in the Science Classroom

This paper reports on a study undertaken with the primary aim of investigating the role of wonder in the learning process. The study was carried out by a 9th grade science teacher in collaboration with a university professor. The teacher taught two classrooms of 27 and 30 students respectively, by trying to evoke a sense of wonder only in one of them. To this end the teacher identified ideas and phenomena as potential sources of wonder and initiated the instruction through these ideas and phenomena. Observation and especially student optional journals were the main instruments of the research. A quantitative analysis of journal entries made by the students of both classrooms, provided evidence for higher involvement for the students??both males and females??of the classroom where the teacher evoked a sense of wonder. Also an analysis of students?? comments provided evidence that wonder, experienced as astonishment and a shock of awareness can help students change their outlook on natural phenomena. Moreover two paper-and-pencil tests administered at the end of the school year provided additional evidence that wonder had an effect on students?? ability to remember ??wonder-full?? ideas and also an effect on better understanding, of at least, three phenomena. This empirical evidence of better retention and understanding is evidence of the role of wonder as an attention catcher and generally of the role of affective factors in the learning process.     

Some Thoughts on the Notion of Purposeful Learning

Constructivism is presented as the inexorable denouement of the qualitative versus quantitative paradigm war. Postmodernism is equated with constructivism, then deconstructed and critiqued in light of rhetorical strategy. The problem of universals is discussed and the solution is elaborated into objectivist pedagogy. Elkind (2005) is cited as an exemplar of postmodern doublespeak and, accordingly, logically refuted. The article concludes that a constructivist monopoly in education ideology is calamitous. The sole curative would be a fundamental change in philosophy; that is, an acceptance of objectivist epistemology.     

Romanticism and Romantic Science: Their Contribution to Science Education

The unique contributions of romanticism and romantic science have been generally ignored or undervalued in history and philosophy of science studies and science education. Although more recent research in history of science has come to delineate the value of both topics for the development of modern science, their merit for the educational field has not been explored. Romanticism was not only an obvious historical period, but a particular state of mind with its own extraordinary emotional sensitivity towards nature. It is especially the latter which we hope to revisit and reclaim for science education. After discussing several key historical contributions, we describe nine characteristics of ‘Romantic Science’ in order to focus on six ideas/possibilities that we believe hold much value for transforming current science education: (1) the emotional sensitivity toward nature, (2) the centrality of sense experience, (3) the importance of “holistic experience”, (4) the importance of the notions of mystery and wonder, (5) the power of science to transform people’s outlook on the natural world, and (6) the importance of the relationship between science and philosophy. It is argued that in view of a pragmatist/utilitarian conception of school science prevalent today the aforementioned ideas (especially the notion of wonder and the poetic/non-analytical mode of knowledge), can provide food for thought for both science teachers and researchers seeking to work out an aesthetic conception, one that complements current approaches such as inquiry science and conceptual change.     

Romantic understanding and science education

This essay outlines the potential role for Kieran Egan’s (1990 Egan K (1990) Romantic understanding Chicago University of Chicago Press  [Google Scholar]) notion of “romantic understanding” in science education. A summary of conventional approaches to science education is followed by a detailed analysis of the implications that romantic understanding may have for the science curriculum, teaching and student learning. In particular the relationship between teaching scientific concepts versus scientific ideas is discussed as well as the possible role in science teaching of inspiration, anticipation, and aesthetic understanding.     

Sport management student as producer: embedding critical management studies in sport through contemporary pedagogy

In recent years there has been growing interest over the role of major sport events and the sports industry. The aftermath of 2008 global crisis exposed the myth of ‘end of history’ and raised several questions over the role of management and organisational practices and theories in all aspects of human activity, including sport. This article reviews the emergence of critical management studies (CMS) as a field within management and organisational studies. We focus on critical performativity theory (CPT) as a key concept of re-configuring managerial practices. We add our voices to those asking for more critical output in sport management and point out the potential contribution of CMS in sport and especially of CPT. Finally, we propose ‘student as producer’ as a pedagogical framework to act as a possible basis for incorporating critical theories into higher education teaching. We argue that this framework can contribute significantly towards providing future graduates with the skills and knowledge to enable them to deal with the contemporary challenges of modern sport’s industry and wider society.     

IoT and AI for Smart Government: A Research Agenda

The Internet of things (IoT) is the network of objects/things that contain electronics, software, sensors, and actuators, which allows these things to connect, interact, and exchange data. The users, sensors, and networks generate huge amounts of data from which governments can develop applications and gain knowledge using Artificial Intelligence (AI) techniques. Thus, IoT and AI can enable the development of valuable services for citizens, businesses, and public agencies, in multiple domains, such as transportation, energy, healthcare, education, and public safety. This guest editorial for the special issue on IoT and AI for Smart Government, identifies the challenges involved in implementing and adopting these technologies in the public sector, and proposes a comprehensive research framework, which includes both IoT and AI elements for smart government transformation. Subsequently, the editorial provides a brief introduction of the six papers in this special issue. Finally, an agenda for future research on IoT and AI for smart government is presented, based on the proposed framework and gaps in existing literature, supported by the papers that were submitted to this special issue. The agenda comprises four directions i.e., conducting domain-specific studies, going beyond adoption studies to examine implementation and evaluation of these technologies, focusing on specific challenges and thus quick wins, and expanding the existing set of research methods and theoretical foundations used.     

Music search engines: Specifications and challenges

Nowadays we have a proliferation of music data available over the Web. One of the imperative challenges is how to search these vast, global-scale musical resources to find preferred music. Recent research has envisaged the notion of music search engines (MSEs) that allow for searching preferred music over the Web. In this paper, we examine the growing research topic of MSEs, and provide potential specifications to follow and challenges to face.
