Getting tense about genealogy

The paper responds to the growing interest in genealogical method as a means of inquiry in education research. The three authors bring together their collective understanding of the nature and purpose of genealogy as a method deriving from the work of Michel Foucault. The authors then indicate how such understandings were applied by each of them to a particular scholarly task. In elaborating the uses and the pitfalls of genealogical approaches by this means, the writers makeit clear that thereis no blueprint for genealogical use. Rather, working through genealogical methods demands from the researcher a strong grasp of the epistemological and theoretical tensions involved in asking how our present educational practices function as they do.

ABSTRACT

This article focuses on primary teachers’ beliefs about teaching and learning and in particular about their preferred ways of teaching; how they integrate National Curriculum requirements into their teaching programmes and their views about stereotyped ‘models’ of pedagogy. The authors conclude that learning and teaching are understood as highly complex and cannot be subsumed under one particular model. They suggest that most primary school teachers adopt an eclectic approach, but that frequently they are confused about the content of the mix or which approach might be most appropriately used in any particular context.     

Survey on reporting of epithelial cells in urine sediment as part of external quality assessment programs in Brazilian laboratories

IntroductionEpithelial cells (ECs) are structures regularly observed during urine microscopy analysis. The correct identification of EC subtypes can be useful since renal tubular epithelial cells (RTECs) are clinically relevant. We investigate the urinary ECs report and the judgement of its clinical importance by Brazilian laboratories.Materials and methodsA survey with four questions was made available to participants of the Urinalysis External Quality Assessment Program (EQAP) from Controllab. Laboratories composed 3 groups: (1) differentiating ECs subtypes: “squamous”, “transitional” and “RTECs”; (2) differentiating ECs subtypes: “squamous” or “non-squamous” cells; (3) without ECs subtype identification. Participants did not necessarily answer to all questions and the answers were evaluated both within the same laboratory’s category and within different categories of laboratories.ResultsA total of 1336 (94%) laboratories answered the survey; Group 1, 119/140 (85%) reported that ECs differentiation is important to the physician and 62% want to be evaluated by EQAP, while in Group 3, 455/1110 (41%) reported it is useful to them, however only 25% want be evaluated by EQAP. Group 2 laboratories 37/51 (73%) reported that the information is important, but only 13/52 (25%) are interested in an EQAP with differentiation of the 3 ECs subtypes.ConclusionMost of the laboratories do not differentiate ECs in the three subtypes, despite the clinical importance of RTECs. Education of laboratory staff about the clinical significance of urinary particles should be considered a key priority.     

Forward acceleration of the centre of mass during ski skating calculated from force and motion capture data

The purpose of this paper was to present and evaluate a methodology to determine the contribution of bilateral leg and pole thrusts to forward acceleration of the centre of mass (COM) of cross-country skiers from multi-dimensional ground reaction forces and motion capture data. Nine highly skilled cross-country (XC) skiers performed leg skating and V2-alternate skating (V2A) under constant environmental conditions on snow, while ground reaction forces measured from ski bindings and poles and 3D motion with high-speed cameras were captured. COM acceleration determined from 3D motion analyses served as a reference and was compared to the results of the proposed methodology. The obtained values did not differ during the leg skating push-off, and force–time curves showed high similarity, with similarity coefficients (SC) >0.90 in the push-off and gliding phases. In V2A, leg and pole thrusts were shown to contribute 35.1 and 65.9% to the acceleration of the body, respectively. COM acceleration derived from ground reaction forces alone without considering the COM position overestimated the acceleration compared to data from motion analyses, with a mean difference of 17% (P < 0.05) during leg push-off, although the shapes of force–time curves were similar (SC = 0.93). The proposed methodology was shown to be appropriate for determining the acceleration of XC skiers during leg skating push-off from multi-dimensional ground reaction forces and the COM position. It was demonstrated that both the COM position and ground reaction forces are needed to find the source of acceleration.     

The effect of playing status,maturity status,and playing position on the development of match skills in elite youth football players aged 11–18 years: A mixed-longitudinal study

This mixed-longitudinal study examined the development of match skills in elite male youth footballers (aged 11–18 years), while considering the effect of playing status, maturity status, and playing position. Across two seasons, 126 elite male youth footballers were assessed in 1–10 competitive matches (401 player-matches). For each match, the on-the-ball actions of each player were recorded using a notation system. The match skills observed were frequencies of successful passes, on-target shots, dribbles, crosses, clearances, and tackles/blocks/interceptions. Multilevel Poisson analysis was used to model the development of players, with regard to each match skill. Modelling revealed significant (p?p?p?p?p?相似文献   

Motivation and attrition in engineering students

In the engineering profession we need to reflect continually on the students we are training, their suitability and ability to become the next generation of engineers, facing an ever-changing future. We need to face our responsibility in helping to develop the skills required for graduates of tomorrow and ensuring that we are not losing our best students to other professions. A survey has been conducted at Imperial College highlighting problem areas of students at risk from demotivation within engineering courses. Forty students who had not completed their course at the college were surveyed and 10 students were interviewed. The issues they raised have been analysed and intervention strategies have been identified which are presently being developed at the college as part of the ongoing quality improvement of courses. It is hoped that the approaches discussed can be disseminated further within Imperial College and to other universities.     

Learning: The pupil's voice

Summaries are given of research on the learner's role in learning and pupils' attitudes to school and it is argued that few studies have collected the views of young children on learning. This provides the rationale for a pilot study which probed the perceptions of a sample of 44 Year 2 and Year 6 children in schools in and around London. The findings indicate that children as young as seven can conceptualise 'learning' and are able to articulate learning strategies and processes they use. It is suggested that the pupil's voice is an increasingly important element in furthering our understanding of teaching and learning more generally.
