Throwing performance in water polo is related to in-water shoulder proprioception

ABSTRACT

Water polo players require a high level of upper-extremity strength, flexibility and coordination to achieve a peak level of throwing performance. Increased levels of shoulder proprioceptive acuity, strength and range of motion (ROM) have been previously associated with higher sporting performance. A coach-rating scale, used to quantify an athlete’s kicking proficiency in soccer; was adapted in the current study to measure each coach’s subjective expert opinion regarding athletes’ throwing mechanics, velocity, and accuracy. To examine this hypothesis shoulder proprioception acuity of 18 water polo players was measured both in-water and on-land using an AMEDA apparatus and correlated with coach-rated throwing performance and clinical measures of shoulder strength and ROM. There was a moderate positive correlation between the in-water and the on-land proprioception acuity (r = 0.47, p < 0.05). The in-water score showing a strong positive correlation with coach rated throwing mechanics (r = 0.68, p < 0.05) and velocity (r = 0.75, p = 0.02), suggesting that superior proprioception acuity contributed to fast, mechanically-efficient throwing. These findings support the notion that in-water proprioceptive acuity is an important determinant of the throwing performance achieved by water polo athletes and its measurement may be a valuable adjunct to current athlete screening.     

The Concept of the ‘Small Secondary School’

School size is becoming an increasingly important factor in discussions concerning school effectiveness, particularly those concerning cost‐effectiveness. Unfortunately, the term ‘small‐school’ is used in several different ways and lacks clarity. This paper examines the present usage of this term in order to construct a definition that could be incorporated into effectiveness research design.     

PISA for Development: how the OECD and World Bank shaped education governance post-2015

ABSTRACT

The year 2015 was significant for the arena of international development, as UNESCO’s Education for All agenda was replaced by Education 2030, which would identify minimum standards of education quality. The OECD had been working on extending its existing PISA assessment into low- and middle-income countries through PISA for Development (PISA-D) and positioned the new assessment as a means of tracking progress on the post-2015 goals. The organisation maintains that PISA-D was introduced primarily in response to the demands of the international community, especially low- and middle-income countries, and that the assessment was developed in partnership with them. This paper investigates those claims through an analysis of the arrival of PISA-D in Cambodia, situating the analysis within UNESCO’s shifting agenda and the strategic visions of the OECD and World Bank that first emerged in the 1990s. The result is a very different picture to the portrayals of local agency, demand, consensus and partnership that adorn the official websites and pamphlets of global agencies and much academic research, raising serious doubts about education governance post-2015.     

EMPIRICAL SYNTHESIS OF THE EFFECT OF STANDARD ERROR OF MEASUREMENT ON DECISIONS MADE WITHIN BRIEF EXPERIMENTAL ANALYSES OF READING FLUENCY

Intervention researchers often use curriculum‐based measurement of reading fluency (CBM‐R) with a brief experimental analysis (BEA) to identify an effective intervention for individual students. The current study synthesized data from 22 studies that used CBM‐R data within a BEA by computing the standard error of measure (SEM) for the median data point from the baseline and intervention data. The median CBM‐R score from the intervention that the authors of each study identified as most effective fell within the SEM (68% confidence interval) of the baseline data approximately 30% of the time, but the ranges for the two author‐identified most effective interventions overlapped over 75% of the time. Extended analyses were consistent with the BEA results for approximately three‐fourths of the instances after considering the SEM of the baseline and intervention phases. Using matched passages did not improve the overlap of the ranges, but there was less overlap when the study used three data points per condition. Results emphasize the importance of considering SEM of CBM‐R data when comparing interventions within a BEA. Further implications for practice and future research are included.     

Digital culture clash: “massive” education in the E-learning and Digital Cultures MOOC

While education has been both open and online, the sizeable enrolment numbers associated with massive open online courses (MOOCs) are somewhat unprecedented. In order to gauge the significance of education at scale, this article analyses specific examples of massive participation derived from E-learning and Digital Cultures, a MOOC from the University of Edinburgh in partnership with Coursera. Student-created content, user statistics, and survey data are illustrated to examine the experiences and repercussions of engaging with educational activity where participants number in the tens of thousands. This activity is shown to mirror established instructionist or constructivist approaches to pedagogy. However, rather than working with “massiveness,” these positions are suggested to oppose large participant numbers. Concluding remarks propose an irreducible diversity of participation, rather than a generalised categorisation of “student,” and call for future considerations of the MOOC to move beyond individualism and self-interest.     

Curriculum change: a study of the implementation of General National Vocational Qualifications

This article focuses on curriculum change, in particular on course team responses to the introduction of a new curriculum and on the implications of empirical findings for our understanding of curriculum implementation and change. The case discussed is that of the second version of GNVQ. The discussion is based on an analysis of data collected across twenty-two course teams in ten schools and colleges over a two-year period as part of an ESRC-funded project. The model of comprehensive assessment of the second version of the GNVQ is one in which the curriculum reinforcement role of assessment related to the coverage and standards of the qualification but not to the design of courses. Theoretically, significant scope was accorded to course teams to develop and provide courses that responded to local contexts. The article explores how patterns of difference and similarity in course team responses to the introduction of this curriculum might be explained and indicates three broad approaches: implementation, adaptation and assimilation, relating these responses to the existing experience and expertise of members of the various course teams. The article draws on concepts from the field of linguistics to put forward the notions of ‘curricular fields’ and ‘sub-curricular fields’ and suggests that curriculum implementation needs to take greater account of the sub-curricular fields of course teams.
