Developing tests of impaired coordination for Paralympic classification: normative values and test–retest reliability

Current methods of assessing coordination in Paralympic classification are non-instrumented and are based on ordinal scales of measurement and therefore impede the development of evidence-based methods of classification. This paper describes an instrumented battery of tests that measure impaired coordination in a way that will permit evidence-based classification. Test–retest reliability and normative values for each of the tests are reported. Twenty participants visited the laboratory on two occasions, each time completing 11 tests: three running-specific, lower-limb reciprocal tapping tests (yielding five outcome measures); four throwing-specific, upper-limb discrete tapping tests (yielding four outcome measures); and four wheelchair-specific, upper-limb reciprocal tapping tests yielding seven outcome measures. Reliability was evaluated using Intra-class Correlation Coefficients (ICCs), Standard Error of Measurement, Limits of Agreement and Paired t-tests. ICCs for fourteen of the 16 outcome measures were excellent (ICC ≥ 0.80), although systematic bias was evident in two of these—a unilateral, running-specific lower-limb tests on the non-dominant side, and a unilateral wheelchair-specific upper limb test on the dominant side. ICCs for two tests—a bilateral wheelchair-specific upper limb test (0.74), and a unilateral wheelchair-specific upper limb test on the non-dominant side (0.54)—were good and fair respectively. Results indicate that 12 of the measures evaluated have measurement properties that will facilitate the development of evidence-based methods of Paralympic classification in athletics. Positional adjustment and increased familiarization may improve reliability in the other four. Studies evaluating reliability of this test battery in people with coordination impairments are warranted.     

The impact of an experiential education program on the self-perceptions and perceived social regard of physical education students

This study investigated the effectiveness of an 8-month Team Building through Physical Challenges (TBPC; Glover & Midura, 1992) program on the self-perceptions and perceived social regard of middle school physical education students (N = 1802). Data were analyzed using multilevel analyses where midpoint and final evaluations were conducted separately. Results revealed that at the midpoint evaluation, students in the experimental and control conditions were not different on any of the subscales assessed. At the end of the program, students in the experimental condition, compared with those in the control condition, showed significantly higher scores on 6 of the 10 subscales assessed and the effect sizes were medium to very large. The findings support the effectiveness of the TBPC program in creating positive psychological outcomes for students in a field-based setting.     

Supply and demand of doctorates in economics

Little is known about the changes in supply and demand for economists. American universities and colleges report the awarding of 12,513 doctoral degrees in economics between 1969 and 1984, with the number randomly varying by over 500 per year. New job listings give an indication that market demand for economists between 1975 and 1984 led the supply and was far more volatile than the number of doctoral degrees awarded. Although the graduate economic specialties over the last 16 years have been relatively stable and the specialties ranked by employers have remained relatively constant, they show no comparative agreement. Graduate students may not be choosing fields of specialization that reflect the market, and institutions may not be responding to market changes.     

City of London School and Communities that Care: Researching Pupil Experience to Inform Policy and Practice in the Independent Sector

This article is an account of the decision by an independent school to participate in its local Healthy Schools Scheme. One of the factors that influenced this decision was the value the school gained from a pupil survey. The same survey was used to track the impact of the school's Personal, Social and Health Education curriculum and pastoral work on pupils' experience of the school, and academic achievement. In particular, the authors explore the role of survey analysis and consultancy advice in interpreting survey results and developing school practice. The survey contributed to pupil participation in school development. The use of an external consultant as critical friend was perceived as an aid to school reflection and self-review.     

Using the Opinions and Lifestyle Survey to examine the prevalence and characteristics of families who home educate in the UK

This paper has two aims, first to examine the feasibility of using an omnibus survey to estimate the prevalence and characteristics of families who home educate and secondly to provide an empirical contribution to recent research on home education in the UK. Because there is no statutory requirement for families who home educate to register with the Local Authority, there are no nationally representative data on the prevalence and characteristics of the home educating population in this country. Therefore gathering data from a fully randomised sample of home educating families would be prohibitively expensive. In this study we used a national omnibus survey to collect data on the homeschooling experiences of over 6000 households from across the UK, of whom 52 were found to have engaged in homeschooling. Our findings estimate that around 1% of families with dependent children have home educated either on a full or part-time basis. Provision of home education was often episodic and reflects the diversity of the home educating population. While the findings presented here largely confirm previous work on home education in the UK, other work tends to be based largely in the home educating community and often lacks a comparison with the general population. Using an omnibus survey like the Opinions and Lifestyle Survey enables researchers to gather data from a nationally representative sample of a small and diverse social group.     

Can creative podcasting promote deep learning? The use of podcasting for learning content in an undergraduate science unit

This paper examines the effect of a podcasting task on the examination performance of several hundred first‐year chemistry undergraduate students. Educational researchers have established that a deep approach to learning that promotes active understanding of meaning can lead to better student outcomes, higher grades and superior retention of knowledge over time. We attempted to promote such an approach by setting a task that involved student collaboration, contextualisation of content, and communication through new media, specifically creative podcasting. Examination results were used as a source of empirical evidence of changes in understanding and retention that occurred for students who completed this task. In comparing results across 2 years on similar questions related to the podcasting topics, we found a statistically significant improvement after introduction of the podcasting task on the questions related to one of the topics on which students had actively created their own podcasts (“acids & bases”), but not on the other (“oxidisation and reduction”). Improved learning outcomes in the form of better understanding and retention over time in at least one case suggest that under some circumstances creative podcasting may indeed help to promote a deep learning approach.     

Determining optimal trial size using sequential analysis

When characterising typical human movement profiles, the optimal number of trials analysed for each participant should ensure a stable mean. Sequential analysis is one method able to establish the number of trials to stability by assessing a moving point mean against a set bandwidth. As the total trial number determining this bandwidth is selected arbitrarily, the effect of applying different total trial numbers on the results of sequential analysis was investigated. Twenty participants performed 30 trials of overarm throwing, and sequential analyses were applied to three dimensional (3-D) kinematic data over 10, 20 and 30 trial numbers. We found a total of 20 to be the preferred trial number for sequential analyses. Erroneous results were produced consistently by 10 trial number groups, while moving point means were statistically unchanged after the 10th trial. Subsequently, sequential analyses were applied to 20 trials to establish trials to stability in discrete and time series elements of the 3-D kinematic data. The results suggest that a trial size between 13 and 17 provides stable means for overarm throwing kinematics.
