The aim of the present study was to examine the factorial validity of the Test of Performance Strategies (TOPS; Thomas et al., 1999) among adolescent athletes using confirmatory factor analysis. The TOPS was designed to assess eight psychological strategies used in competition (i.e. activation, automaticity, emotional control, goal-setting, imagery, negative thinking, relaxation and self-talk,) and eight used in practice (the same strategies except negative thinking is replaced by attentional control). National-level athletes (n = 584) completed the 64-item TOPS during training camps. Fit indices provided partial support for the overall measurement model for the competition items (robust comparative fit index = 0.92, Tucker-Lewis index = 0.88, root mean square error of approximation = 0.05) but minimal support for the training items (robust comparative fit index = 0.86, Tucker-Lewis index = 0.81, root mean square error of approximation = 0.06). For the competition items, the automaticity, goal-setting, relaxation and self-talk scales showed good fit, whereas the activation, emotional control, imagery and negative thinking scales did not. For the practice items, the attentional control, emotional control, goal-setting, imagery and self-talk scales showed good fit, whereas the activation, automaticity and relaxation scales did not. Overall, it appears that the factorial validity of the TOPS for use with adolescents is questionable at present and further development is required.  相似文献

This paper explores a project funded through the National Network of Libraries of Medicine to enhance effective use of the Internet by public health professionals. The processes and outcome of an effort to develop a statewide Web site for public health professionals are described. A series of focus groups was conducted as a preliminary data-gathering tool to evaluate the information needs of the target population. Results of the focus group provided a valuable framework upon which to build a successful schema for Web site development.  相似文献

This paper examines the extent to which the South African Library and Information Science (LIS) agenda maps to the national agenda for the reconstruction and development of the country, which is geared to the elimination of poverty and inequality. The nation has been described as comprising two societies: the one modern and well developed, the other characterised by masses of people living in dire poverty. The mandate of LIS in South Africa includes supporting and stimulating the technological and information development of all communities and providing effective LIS education to meet this goal. The government has embraced the concept of the Information Society, emphasising the link between economic growth and Information and Communication Technologies (ICTs) and has pointed to the need for information literacy education. We present a critique of the fit between LIS policies and practices (including the curriculum) and the needs of an emerging democracy and its development goals, challenged by the duality of globalisation and marginalisation.  相似文献

It has been argued that the use of Information and Communications Technologies has made academic dishonesty easier but this does not necessarily mean that it is more prevalent. The study presented here investigated the attitudes to, and extent of, self‐reported involvement in Internet supported dishonest academic practices. Multiple linear regression analyses showed that Internet experience, acceptability of cheating and assessment of risk predicted an individual student's acceptance of acts such as plagiarism as a legitimate way to achieve academic goals. There was a complex interrelationship among gender, frequency of Internet usage, and maturity of students. Academic offences tended to be more acceptable to males, but also to active Internet users, who were often female: that is females who joined the Internet culture were more prone to plagiarise than their non‐active peers. New undergraduates were more likely to err than students in later years of their degree. These results show that there are a number of interrelated factors impacting on individuals’ willingness to commit academic offences. The final discussion of this paper both recognises that Internet supported academic offences occur and briefly outlines some technical and non‐technical responses that should be considered by faculty to ameliorate this problem.  相似文献

This study examined learning in the domain of sentence parsing and syntax treediagram construction. The aim of the study was to assess whether subjects could learn vicariously from recordings of interactions between a previous student and a tutor.Four intervention conditions and a control condition were compared. Subjects in a dialogue group (DL) read printed tutorial notes and subsequently vicariously viewed dynamic (animated) recordings of tree diagrams being constructed by a previous student in the presence of a tutor.The discourse (DI) condition was similar except that subjects viewed recordings of tree diagrams being constructed by a tutor who concurrently verbalised instructional discourse.In a third condition (DO), subjects viewed tree-diagram construction animation clips which were not annotated with either dialogue or discourse. In a linear text (LT) condition, subjects were given only printed tutorial notes. A control (CO) condition involved pre and post testing without any intervention.Results indicated that the dialogue condition was as effective as the discourse condition. This provides support for contention that re-usable dialogue is a useful resource for the vicarious learner. Another finding was that un-annotated animated diagrams were surprisingly effective. Several reasons for their effectiveness are suggested from the literature on instructional animations.  相似文献

This article analyses findings from two studies conducted collaboratively across two educational settings, New Zealand and England, in 2001–2002. These studies examined the impact of national educational policy reforms on the nature of primary teachers’ work and sense of their own professionalism and compared these impacts across the two countries. Adopting a policy ethnography approach, using in‐depth interview data from samples of teachers in each country, it is argued that there have been discursive shifts in the meaning of the three key terms, autonomy, altruism and knowledge, embodied in the classical professionalism triangle. These shifts reflect policy‐makers’ moves from a ‘professional‐contextualist’ conception of teacher professionalism towards the ‘technocratic‐reductionist’ conception that accompanies neo‐liberal educational reforms in many countries. Teachers in both countries experienced increasing constraints on their autonomy as they became far more subject to ‘extrinsic’ accountability demands. Whether these demands were perceived as enhancing or diminishing teacher professionalism depended on the manner in which they were filtered through the profession’s defining quality, namely teachers’ altruistic concerns for the welfare of the children in their care.  相似文献

Abstract

Doping research has predominantly been framed through an ethical lens, implicitly restricted to the realms of elite sport. Despite increasing anecdotal evidence of growing prevalence rates amongst recreational athletes, such as bodybuilders, these populations have largely been neglected within psychological research. This study aims to develop a theoretical framework relevant to these athletes. Data were collected over a five-month period from an online community forum dedicated to recreational bodybuilders. Purposive sampling was used to gather 118 webpages of doping-related discussion, which were qualitatively analysed using grounded theory applying Strauss’s coding paradigm. Inductive categories were integrated into a motivational framework that related recreational doping to social validation. Categories included the online community’s rite of passage, normative-inferences that facilitated doping, and deterrence factors related to fear of perceived health risks. Findings demonstrate that, for recreational bodybuilders, psychosocial processes are significantly related to doping motives, and that health factors are primary doping deterrents.  相似文献

The purpose of this study is to examine the effect of state-mandated policy, emphasizing control through performance-based instruction and student test scores as the basis for determining school accreditation, on the teaching and learning of science. The intended consequence of instigating the rational theory of management by one state is to improve their current level of student literacy. However, some contend that the implementation of the policy has results that are not intended. The identification of the tension between the intended and unintended results of centralized policy making is the basis for examining a specific case in which the rational model is implemented. One hundred and sixty-five seventh-grade science students and four teachers are participants in the study. Qualitative analysis is the research methodology used as a means to provide detailed information about the contextual nature of the classroom processes. The intention is to identify and describe features of the behavior setting that influence the behavior of the teachers and their students. Three assertions generated during the field work were: Teachers redefine the goals of science instruction as the acquisition of facts and isolated skills, teachers alter their usual instructional behavior to implement uniform instructional procedures, and the teacher/student classroom interaction constrains students' opportunities to learn science. The implications of the study indicate that the state-mandated policy has results that are in opposition to the intended results. Instead of improving the practices of teachers, the implementation of the policy constrains and routinizes the teachers' behavior, causing them to violate their own standards of good teaching. They feel pressured to “get through” the materials so students will score well on tests. The classroom interaction is structured in such a way as to inhibit students from asking questions of their own. As a result, students' opportunity to express curiosity and inquiry—central processes in scientific thinking—are constrained. These unintended consequences of the implemented state policy, instead of improving science teaching and learning, continue to reduce science instruction to the literal comprehension of isolated facts and skills.  相似文献
