Effects of Physical Eduction Taught by a Specialist on Physical Fitness and Self-Image

Abstract

The AAHPER youth fitness test and Gordon's “How I See Myself” scale were administered to 75 grade 7 students. The subjects were divided into those with elementary school physical education provided by a specialist (N=46) and those from schools with no such specialist (N=29).

Those subjects who were taught by a specialist participated in experiences in rhythmic activities, group games, tumbling and gymnastics activities, and other individual and dual activities each week. The atmosphere was free from threat, providing opportunities for each child to experience a degree of success and yet be challenged further each day.

Results indicated that the subjects with the experience of working with a physical education specialist performed at a higher level and were more able to assess themselves accurately than were those subjects who had not worked with a physical education specialist in the elementary school.     

Development and preliminary validation of the Cricket Mental Toughness Inventory (CMTI)

Abstract

The purpose of this research project was to develop a psychometrically sound measure of mental toughness in cricket, using a multi-method research design. Two qualitative studies in which current and former cricketers' (n = 16) perceptions of the key components of mental toughness in cricket and the suitability of an item pool to target those key components (n = 9) were assessed. We then conducted two quantitative studies to examine both the within- and between-network properties of the Cricket Mental Toughness Inventory (CMTI) using confirmatory factor analysis and correlations. Support for the existence of a five-factor, 15-item model was revealed with three independent samples of cricketers; two contained cricketers from several different countries (n = 285 and 285), whereas one contained Australian cricketers only (n = 433). Each of the five subscales (affective intelligence, attentional control, resilience, self-belief, and desire to achieve) were positively correlated with dispositional flow, hardiness, and resilience and negatively correlated with athlete burnout. Although requiring replication and extension, the results of the present study provide preliminary support for the factor structure, internal reliability, and construct validity of the CMTI.     

Development and validation of a method to directly measure the cable force during the hammer throw

The development of cable force during hammer-throw turns is crucial to the throw distance. In this paper, we present a method that is capable of measuring cable force in real time and, as it does not interfere with technique, it is capable of providing immediate feedback to coaches and athletes during training. A strain gauge was mounted on the wires of three hammers to measure the tension in the wire and an elite male hammer thrower executed three throws with each hammer. The output from the gauges was recorded by a data logger positioned on the lower back of the thrower. The throws were captured by three high-speed video cameras and the three-dimensional position of the hammer's head was determined by digitizing the images manually. The five best throws were analysed. The force acting on the hammer's head was calculated from Newton's second law of motion and this was compared with the force measured via the strain gauge. Qualitatively the time dependence of the two forces was essentially the same, although the measured force showed more detail in the troughs of the force–time curves. Quantitatively the average difference between the measured and calculated forces over the five throws was 76 N, which corresponds to a difference of 3.8% for a cable force of 2000 N.     

Development of a supported self-directed learning approach for anatomy education

The ability to deliver sufficient core anatomical knowledge and understanding to medical students with limited time and resources remains a major challenge for anatomy educators. Here, we report the results of switching from a primarily didactic method of teaching to supported self-directed learning for students studying anatomy as part of undergraduate medicine at the University of Edinburgh. The supported self-directed approach we have developed makes use of an integrated range of resources, including formal lectures and practical sessions (incorporating gross anatomy specimens, medical imaging technologies, anatomical models, clinical scenarios, and surface anatomy workstations). In practical sessions, students are provided with a custom-made workbook that guides them through each session, with academic staff, postgraduate tutors, and near-peer teaching assistants present to deal with misunderstandings and explain more complicated topics. This approach retains many of the best attributes of didactic teaching but blends them with the advantages associated with self-directed learning approaches. The switch to supported self-directed learning-initially introduced in 2005-resulted in a significant improvement in anatomy examination scores over the subsequent period of five years, manifesting as an increase in the average anatomy practical spot examination mark, less students failing to obtain the pass mark and more students passing with distinction. We conclude that the introduction of supported self-directed learning improved students' engagement, leading to deeper learning and better understanding and knowledge of anatomy.     

Extending participation in standard setting: an online judging proposal

In order for standard setting to retain public confidence, it will be argued there are two important requirements. One is that the judges’ allocation of students to performance bands would yield results broadly consistent with the expectation of the wider educational community. Secondly, in the absence of any change in educational performance, that the percentages in the corresponding bands should be stable over time. It is argued that the use of a small team of judges makes it more difficult to satisfy these conditions. However the cost and logistics of organizing a larger number of judges in the time-pressured atmosphere of public examining can lead to sub-optimal standard setting. Two parallel systems of awarding performance bands are empirically compared, one based on teams of six judges, the other based on a population of teachers. It is shown that the latter system gives more stable results over time for the same large student population. A proposal is outlined for extending participation in standard setting through the web-based presentation of materials and the capturing of cutscores from a population of teachers.
