Tool for Assessing Responsibility-Based Education (TARE): Instrument Development,Content Validity,and Inter-Rater Reliability

Numerous scholars have stressed the importance of personal and social responsibility in physical activity settings; however, there is a lack of instrumentation to study the implementation of responsibility-based teaching strategies. The development, content validity, and initial inter-rater reliability testing of the Tool for Assessing Responsibility-Based Education (TARE) are described here. Inter-rater agreement was calculated for paired observations focused on 2 different teachers delivering a total of 18 separate physical education lessons for students in grades 1 through 6. Findings indicate that the Tool for Assessing Responsibility-Based Education provides scores with adequate inter-rater reliability. The procedures employed in this study proved feasible and enable observers to characterize the implementation of responsibility-based teaching in physical education. The Tool for Assessing Responsibility-Based Education has numerous research and training applications relative to the Teaching Personal and Social Responsibility model (Hellison, 2003 Hellison, D. 2003. Teaching responsibility through physical activity, 2nd, 15–38. Champaign, IL: Human Kinetics.  [Google Scholar]) and the national content standards for K–12 physical education, specifically Standard 5: Exhibits responsible personal and social behavior that respects self and others in physical activity settings (National Association for Sport and Physical Education, 2004 National Association for Sport and Physical Education (NASPE). 2004. Moving into the future. National standards for physical education, 2nd, 39–43. Reston, VA: Author.  [Google Scholar]).     

A program for excellence in physics and physical science teaching

Conclusion It seems reasonable to conclude that the impact of these projects has been extensive and that we have met our basic objectives regarding the improvement of science education for the target teachers and students. The long-term goal of improved scientific literacy of at least a part of the citizens of this country and world can only be assessed by some form of longitudinal study that is beyond the scope and funding for these projects. But our assessment of what has been accomplished in the short term efforts seems to indicate very positive gains in those areas of knowledge, confidence, and pedagogical capability that we believe will enable the participants to make contributions to the improvement of scientific literacy for the students with whom they work. In short, we believe we have had two successful and worthwhile programs that have been useful and effective.     

“All for One and One for All?” - Knowledge broker roles in managing tensions of internal coopetition: The Ubisoft case

Coopetition, i.e., cooperation between competing actors, has become a pervasive strategy for innovative firms. The primary focus of studies investigating coopetition centers on inter-firm relationships, highlighting the benefits, limits and configurational patterns of cooperative relationships between competing firms. Only a small, emerging group of studies seeks to extend the concept to the intra-firm level, stressing the existence and effects of competition and cooperation between units that are part of the same organization. This paper contributes to this latter group by investigating the effects of internal coopetition on knowledge and innovation sharing and highlighting the fundamental role of knowledge brokers in managing the resulting tensions. Based on a qualitative case study of the video game publisher Ubisoft, we stress how the tensions raised by internal coopetitive settings limit knowledge sharing between units, and we analyze the mechanisms through which the knowledge broker helps to overcome these limits. We identify three main functions of this knowledge broker that allow the promotion of knowledge and innovation transfer to occur between coopeting units: (1) protecting the unit’s competitive advantage by introducing a lagging principle in the transfer process, (2) reducing sharing costs by standardizing innovative solutions, and (3) enhancing awareness of and trust in innovative solutions by centralizing knowledge diffusion.     

A follow-up study of students using portable computers at a secondary school

This paper reports on the findings of a 1999 study that set out to investigate the current perceptions of students and teachers towards the use of portable computers at a secondary school. The aim was to compare these with the findings of a 1995 study carried out by the researcher at the same school. Data were collected from 102 Year Twelve students (17 year old), 104 Year Eight students (13 year old) and 40 teachers. The results indicated that for the Year Twelve students the computers had been of limited value while the Year Eight students appeared to be divided with about a quarter indicating negative attitudes. For the younger students the computers appeared to be used more often and for a greater range of tasks. Many teachers indicated concerns about the management of computers in the classroom and linking computer use to learning outcomes. These perceptions underline the need for targeted professional development, systematic support for the development of student computer-related skills, and changes in the curriculum towards more learner-centred approaches.     

The long-term athlete development model: physiological evidence and application

Within the UK, the "Long Term Athlete Development" (LTAD) model has been proposed by a variety of national governing bodies to offer a first step to considering the approach to talent development. The model, which is primarily a physiological perspective, presents an advancement of understanding of developing athletic potential alongside biological growth. It focuses on training to optimize performance longitudinally, and considers sensitive developmental periods known as "windows of opportunity". However, it appears that there are a number of problems with this theoretical model that are not necessarily transparent to coaches. Principally, the model is only one-dimensional, there is a lack of empirical evidence upon which the model is based, and interpretations of the model are restricted because the data on which it is based rely on questionable assumptions and erroneous methodologies. Fundamentally, this is a generic model rather than an individualized plan for athletes. It is crucial that the LTAD model is seen as a "work in progress" and the challenge, particularly for paediatric exercise scientists, is to question, test, and revise the model. It is unlikely that this can be accomplished using classical experimental research methodology but this should not deter practitioners from acquiring valid and reliable evidence.     

A further analysis of the ethics of representation in virtual reality: Multi-user environments

This is a follow-up article toPhilip Brey's ``The ethics of representation andaction in Virtual Reality' (published in thisjournal in January 1999). Brey's call for moreanalysis of ethical issues of virtual reality(VR) is continued by further analyzing issuesin a specialized domain of VR – namelymulti-user environments. Several elements ofBrey's article are critiqued in order to givemore context and a framework for discussion.Issues surrounding representations ofcharacters in multi-user virtual realities aresurveyed in order to focus attention on theimportance of additional discussion andanalysis of specialized aspects of VR.     

Why relationships matter

Nurture groups (NGs) are a form of provision for children with social, emotional, behavioural and learning difficulties. Although the first groups were established over 30 years ago, growth in the number of NGs in the UK has been exponential over the past ten years. This study attempts to assess the effectiveness of NGs in promoting positive social, emotional and educational development. The study set out to measure: (1) the effects of NGs in promoting pupil improvement in the NGs; (2) the extent to which these improvements generalised to mainstream settings; and (3) the impact of NGs on whole schools. Statistically significant improvements were found for NG pupils in terms of social, emotional and behavioural functioning. NGs which had been in place for more than two years were found to be significantly more effective than groups which had been in existence for less than two years. Pupils with SEBD in mainstream classrooms improved in behavioural terms significantly better than pupils with and without SEBD attending schools that did not have NG provision. The greatest social, emotional and behavioural improvements took place over the first two terms, whilst improvements in behaviours associated with cognitive engagement in learning tasks continued to improve into the third and fourth terms. This study suggests that NGs are a highly promising form of provision for young children with a wide range of SEBDs. There is also good evidence to suggest that successful NGs contribute to the development of the ‘nurturing school’.     

Publishing,copyright, and the public good

For centuries publishers have acted as intermediaries between author and audience. Copyright, like freedom of expression, is an essential element of freedom in this role, because without it authors' rights are not fully protected. Only when they are protected against theft and other economic or moral infringements are authors free to express themselves without fear. Publishers, too, rely on copyright to protect their investments and their freedom Paul Nijhoff Asser has been secretary of the International Group of Scientific, Technical and Medical Publishers (STM), Amsterdam, since 1970. He has been active in publishing and bookselling for more than forty years. This article was adapted from a presentation at the seminar “East Meets West: Copyright and the Publisher in a Market Economy”, Hamburg, March 1991.     

Constructive Empiricism and the Metaphysics of Modality

James Ladyman ([2000]) argues that constructive empiricism isuntenable because it cannot adequately account for modal statementsabout observability. In this paper, I attempt to resist Ladyman'sconclusion, arguing that the constructive empiricist can granthis modal discourse objective, theory-independent truth-conditions,yet without compromising his empiricism.
