Abstract

A total of 165 adolescent boys took measures of physical fitness, general self-esteem, and attitudes toward physical activities. High-fit compared to low-fit boys were higher in self-estimates of physical ability (P < .007) and self-reported attraction to physical activities (P < .007) but not significantly different in general self-esteem nor in reported extent of participation in voluntary physical activities. In addition significant correlations were observed between self-estimates of physical ability and attraction to physical activity, and between attraction to physical activity and extent of voluntary participation in physical activity.  相似文献

Abstract

During the first ten days of the academic year the Physical Estimation and Attraction Scales (PEAS) and Bialer's Locus of Control Scale were administered to seventh and eighth grade middle school males. Subsequently, calls were issued for the fall sport season (flag football, cross-country). Stepwise discriminant analysis produced a function containing Attraction first and Estimation second, which accurately predicted athletic participation, canonical r = .35 p < .001. Use of smaller, previously factored collections of PEAS items improved the prediction, canonical r = .40, p < .001. Prediction of a single, more specific activity, cross-country, by means of the more specific factor scores produced a canonical coefficient of .47, p < .001. PEAS Factor 5, referring primarily to activities of running and hiking, developed the largest relationship with cross-country participation of any study variable. Control did not enter either of these two equations. No significant relationship was found between any study variable and adherence (remaining on the cross-country team for the complete season). It was concluded that PEAS variables are capable of predicting initial exercise involvement. In terms of developing optimal psychometric predictions of exercise recruitment and adherence, it is recommended that attitude statements be developed which are more specific and congruent to corresponding desired behaviors.  相似文献

This study tested a computer‐aided coaching analysis instrument (CAI) as part of an intervention strategy designed to modify verbal coaching behaviour. Four coaches were observed and analysed over 12 practice sessions. Coaches A, B and C received intervention feedback through CAI data, where selected behaviours were highlighted for discussion, and videotape images were used to illustrate discussion points. Coach D was provided with videotapes of his own performance and told to formulate and implement any of his own recommendations. The CAI data are primarily quantitative, so target values were created for the different dimensions of verbal behaviour. This benefited the coaches in interpreting their effectiveness and provided a reference to evaluate the magnitude of change. Written journals and audiotape recordings were also used to promote insight into the complexity of verbal behaviour and the ‘human factors’ (e.g. relationship with players, attitude to researcher) that affect behaviour modification.

Instructional effectiveness was assessed by time‐series analysis. There was evidence from each behaviour dimension that change can occur and be maintained as a result of exposure to the CAI intervention strategy. However, this is clearly contingent upon the coach understanding what is asked of him or her, and remains focused and committed to changing these particular behaviours. The analysis of Coach D's behavioural change suggests there are limitations to the sensitivity of discretionary viewing, as only two dimensions of behaviour were identified for, and resulted in, positive change. The results of this study provide support for Locke's (1984) contention that behaviour modification can occur by using data as direct feedback, as reinforcement and as information in the form of recommendations. However, the study also illuminates several factors that can negate the modification and maintenance of verbal coaching behaviour.  相似文献

The relationship of technology policy to economic and industrial development has become a subject of debate between those who argue that market forces should determine how technology is produced and used and those who believe that government has a role in supporting investment in technology use and the development of high‐technology industries. This article looks at the effects of national technology policy in promoting the production of computer hardware and software in Asia‐Pacific countries during the 1980s. It also analyzes the relationship between various environmental factors and computer production and looks at the interaction between environment and policy. It finds three types of environmental factors associated with level of computer production: human resources, in the form of scientists and engineers; the presence of complementary industries, particularly electronics production; and expenditures on research and development. It also finds that hardware production is higher in countries with national computer plans but that software production does not appear to be associated with efforts by the government to promote the computer industry.  相似文献

The World Bank was the first cooperation agency seriously to explore the implications for itself and its clients of the heightened role of knowledge in economic and institutional development that had become increasingly evident in OECD countries. Beginning with its president's decision in 1996 to become 'the Knowledge Bank', different elements within the Bank went on to elaborate a knowledge discourse, most notably within the World Development Report on Knowledge for Development (1998), as well as a whole series of 'knowledge projects' and 'knowledge-based initiatives'. The article examines some of the tensions and debates that are at the very heart of the Bank's desire to become a knowledge agency. Amongst these, some of the more salient are the implications of the new knowledge discourse for the Bank's changing priorities towards education; the trade-off between knowledge sharing for the improved efficiency of Bank operations versus knowledge development by the Bank's clients; and the use of information and communications technology to create a global knowledge hypermarket, called the Development Gateway.  相似文献

The paper describes the development and validation of a group test of integrated process skills. The test assesses student performance on a set of twelve objectives related to the generic objective: planning and conducting an investigation. Evidence of content validity, construct validity, and reliability are presented in the paper. A range of generalizability coefficients from 0.77 to 0.98 is reported for specific uses of the 24-item test. Since the items measure performance on objectives that can be readily translated into classroom activity, the test has direct applicability to classroom based research, and evaluation of instruction. In addition to sound psychometric properties, the Test of Integrated Science Processes is distincitve because it includes a set of interrelated, cumulative objectives which reflect autonomous problem solving.  相似文献

The focus of this investigation was on relationships between teaching behaviors and student engagement in 13 middle school science classes. The results indicated that seven managerial variables and four instructional variables were significantly related to student engagement rates. Also the types of tasks allocated by teachers in science lessons were significantly related to the types of tasks undertaken by students. A canonical correlation analysis indicated significant relationships between three allocated task dimensions and three student engagement dimensions. Although teachers allocated adequate time for students to engage in investigation planning, data collecting, and data processing, the results indicated that overt engagement was prevalent only when data were collected. Attending was the predominant type of student engagement when investigations were planned and data were processed. The percentage of student time on task was approximately 63%. Rates of student off task behavior tended to be consistently high across all types of allocated tasks.  相似文献

ABSTRACT:  Lifelong learning is something which one does for oneself that no one else can do for one: it is a public and personal human activity, rather than private or individualistic. One of the features of the education system is the paucity of a language for learning as process and participative experience. Personalised learning requires a sense of the worthwhileness of 'being a learner'– a virtue in the 21st century. A sense of one's own worth as a person is essential to understanding one's identity as a learner. Research suggests the human capacity to learn can be understood as a form of consciousness which is characterised by particular values, attitudes and dispositions, with a lateral and a temporal connectivity. This 'consciousness' has several dimensions which are all related to becoming a person, with a learning identity. They also enable the learner to become aware of and appropriate what is of worth and map onto the sorts of core values that learning communities espouse. Awareness of self and of one's own worth as a person is a necessary condition for 'becoming a learner' and for identifying and engaging with 'what is of worth'. Furthermore, a sense of self as a learner is formed in relationship, and understood as one learns to tell one's own story, as a participant in the conversation of the learning community. Character is the way in which we refer to that quality of personhood in which there is rooted the capacity to change and learn over time.  相似文献

The association of protective resources, personality variables, life events, and gender with anxiety and depression was examined with university students. Building on regression analyses, a structural equation model was generated with good fit, indicating that with respect to both anxiety and depression, negative life events and coping resources were mediated by a common distress factor. Personality variables were associated with anxiety, which in turn had a direct relationship to depression.  相似文献
