There is no widely accepted tool to assess an orthopedic surgeon’s technical skill in the operating room. With changes in surgical education, simulators are being investigated for learning and assessing technical skills, but a link between the actual operating room is needed to ensure they are effective. Hip fracture surgery is a good starting point to develop these measures because hip fractures are common and fixation is a difficult task. Resident orthopedic surgeons wore a head-mounted video camera during hip fracture surgery. Data collected included: duration, number of x-ray images, the supervising surgeon intervention, and tip-apex distance (TAD, a measure of how accurate the implant is placed). To determine the reliability of these measurements, four raters performed them for two cases. Ten raters measured the tip-apex distance (TAD) on 7 cases. These performance metrics for 15 cases were compared to experience of the residents, both point in residency and number of previous cases. A composite performance score was computed using the four metrics. The metrics were also compared to two practicing surgeons’ assessment of skill. The inter-rater reliability of the performance metrics was high (0.97-0.99) showing these measures are consistent between different raters and useful for assessment. There was a significant relationship between resident experience and the metrics of duration and TAD. Expert opinion was related to duration. These metrics provide objective assessment of resident technical performance in the operating room by a non-expert, an important step towards competency based education. Their validity is shown with correlation to surgical experience.

The present study used a sample of 171 college students from the University of South Florida to examine the effects of different types of mental practice on dart-throwing performance. This study examined the effects of imagery and video modeling on an immediately following physical task As suspected, the video modeling condition under these circumstances was associated with poorer performance than the imagery and control conditions. The imagery condition, however, resulted in no difference in performance from the control condition. Discussions of the results and future avenues of research (including gender effects) are also mentioned.

Political skill has been described as using human resources and manipulating social exchanges to influence group outcomes (Mintzberg, 1983). Researchers have found that political skill has significant relationships with constructs such as contextual performance, career satisfaction and leadership. Based on these empirical findings it may be beneficial to include a measure of political skill as part of a selection process. In this study, different methods were explored for measuring political skill that may be appropriate for administrative purposes such as the self-rated questionnaire called the Political Skill Inventory (PSI), a situational judgment test (SJT) and the structured interview. A sample of 100 graduate business students, most of whom had extensive managerial experience, completed the previously mentioned measures in exchange for feedback on their assessments. The participants were subsequently rated on political skill by their coworkers. The only significant association with the coworker scores was the PSI; neither the SJT nor the structured interview showed a significant relationship with the peer ratings of political skill. However, there were unforeseen technical limits to the measures that might explain the negative findings. The paper concludes with recommendations for improving the measures prior to a follow-up study.

Behavioral coaching procedures have been evaluated and enhanced over the years to find the most effective interventions for athletic performance in a variety of sports settings. Different types of feedback have been evaluated for effectiveness in teaching and improving skills. The purpose of this study was to examine the effects of video modeling and video feedback to improve technique for three novice individuals in a fitness program incorporating Olympic weightlifting. Two weightlifting events, the clean and jerk and snatch, were targeted for intervention. Each lift was broken down into a task analysis, and trainers used the task analysis to score each lift. Video modeling and video feedback was effective in improving all three participant's lifts from baseline. Annie's lifts improved from 37% in baseline to 79% in intervention for the clean and jerk, and 24% to 75% for the snatch. Rich's lifts improved from 79% in baseline to 95% following intervention for clean and jerk, and 58% to 89% for the snatch. Fran improved from 60% to 87% on the clean and jerk, and from 51% to 84% on the snatch.

Teaching in Australia is acknowledged as a profession. The public, however, generally perceives teaching as a poorly paid occupation whose practitioners exert little control over their own standards of practice. Consequently, the professional status of teachers is low, and very few of the most capable school leavers and high ability university graduates are attracted to teaching as a career. Furthermore, teachers' perceptions that the public does not appreciate their work have led to low morale, high rates of resignations, and early retirements among experienced practitioners. These factors will contribute to serious shortages of teachers in the new millennium. In the past Australian employers in both government and non-government school sectors have attempted to circumvent teacher shortages by reducing qualifications required for teaching. This anti-professional practice has contributed to the belief that teaching is something that anyone can do. It is argued in this thesis that the status of the teaching profession in Australia must be enhanced if teaching is to attract capable new recruits and retain knowledgeable, experienced practitioners. This could be achieved by giving teachers greater responsibility for their profession's standards through a system of statutory regulatory boards, comprised largely of practising teachers. The boards would be responsible for establishing and enforcing standards for registration of teachers, accreditation of teacher education, and provision of advanced certification. Furthermore, such regulation of the profession should be on a national basis to ensure that all children in all schools in Australia have access to competent, professionally qualified teachers, and to overcome the problems of interstate mobility of teachers. The thesis concludes by calling on all stakeholders to acknowledge teaching as a full profession. This could be achieved by accepting that teachers should regulate their professional standards in the same way that other professions do. A model to achieve that end is presented. / Doctor of Philosophy (PhD)

Teaching (in this study, coaching) is a key determinant in learning any sports skill. The coach-athlete relationship is one of the most important influences on athlete's motivation and performance (Mageau & Vallerand, 2003). One of the key leadership roles the coach has in this relationship is the creation and maintenance of the sports class learning climate. The joint influence of the athlete's motivation and the environmental press (class learning climate) can determine the cognitive, affective, and performance patterns regularly displayed by athletes (Ntoumanis & Biddle, 1999). A sports class' learning climate is a set of internal characteristics that has an important role in shaping an athlete's motivational and behavioural pattern (Ames, 1992) and is a key characteristic of class effectiveness. In sports classes, motivational climate is a sub-set of the overall learning climate and is created primarily by the sport class coach. Motivational climate can be described as the participants' relatively persistent collective perceptions of the achievement goal structure of that setting. Recent studies of motivational climate in sport have provided insight into coaching behaviour and its effect on sports class motivational climate (Ntoumanis & Biddle, 1999). In spite of the potential value of class learning climate research to the field of sports class behavioural studies, no research has consolidated the fields of classroom learning climate research and sports class motivational climate studies. This study provides a model for the investigation of gymnastics sports class learning climates that involves a consolidation of the dimensions and items of the Perceived Motivational Climate in Sport Questionnaire-2 (Newton, Duda, & Yin, 2000) and the Classroom Environment Scale (Moos & Trickett, 1987). The development and validation of a new, unique learning climate scale - the Sports Class Environment Scale (SCES) - constitutes the focus of this research. The process of developing this consolidated instrument began with the production of an initial scale, and was followed by a review by a panel of experts in coaching and independent university researchers in sport and physical education. The SCES draft was then pilot tested with a small group (n = 41) of competitive gymnasts to prompt some changes to the scale. Initial field-testing of the SCES occurred with 28 male and 180 female competitive gymnasts from 6 metropolitan and 4 regional competitive gymnastics clubs in Queensland, Australia. Exploratory factor analysis provided a revised SCES with five subscales labeled Task Involvement and Improvement, Ego Involvement and Mistakes, Coach-Athlete Communication, Effort, Order and Organization, and Affiliation. Using the revised SCES subscales as dependent variables, multivariate analyses of variance were conducted to compare club type, gender, and competitive level. In this study, the low training hours and the high training hours gymnastics classes were different in their perceptions of the Ego Involvement of their class climate. Male and female gymnasts were different in their perceptions of Ego Involvement, Affiliation, and Effort, Order and Organization aspects of their class climates. This study demonstrates the potential utility of creating class learning climates high in both Task Involvement and Ego Involvement for competitive gymnastics clubs. This study breaks new ground, and may lead to novel insights into sports class learning climates. Because class learning climate is easier to manipulate than individual achievement goal dispositions (Whitehead, Andree, & Lee, 1997) and because perceptions of learning climate account for variance in learning outcomes beyond that attributable to student ability (Fraser, 1994, 1998, 2002), class learning climate is an important variable that should be better understood, described, developed, and manipulated. Effective measurement of sports class learning climates using the SCES may lead to a greater understanding of effective sports classes, and of coach and athlete behaviours in those classes, and provides a first step in monitoring sports class learning climates.

Electronics technicians are frequently required to diagnose faults in equipment but are not provided with adequate training in TAFE Colleges. Hardware fault simulators currently used in TAFE Colleges for diagnostic skill development simulate only a few types of equipment and rapidly become obsolete. FAULTSIM is a computer-based simulator in which modern technology is combined with existing simulation techniques to produce a versatile aid to diagnostic skill development. In the design of the new simulator, attention has been given both to the technical features contributing to its effectiveness and to the factors favouring its adoption by teachers.

The purpose of this study was to find whether cross training could improve male adolescent rugby skills. Three major sports (soccer, basketball and wrestling) were selected to form the base of the cross training intervention program. Pre- and post-tests were performed with the entire rugby squad (24 participants) prior to and at the conclusion of the intervention program. After pre-testing, the participants were grouped into either the intervention (12) or the control group (12). Supervised cross training sessions were performed twice a week for 10 weeks as well as traditional rugby training twice a week for 10 weeks with the intervention group. The control group performed supervised conventional rugby training twice a week for 10 weeks. All participants (24) played in a rugby match once a week during the 10 week period of the study.
