How can pre-service primary teachers' perspectives contribute to a pedagogy that problematises the ‘practical’ in teacher education?     

Déirdre Ní Chróinín  Ailbhe Kenny  Elaine Murtagh  Elaine Vaughan 《Irish Educational Studies》2013,32(2):251-267

This study examined pre-service primary teachers' perspectives on teaching and learning experiences within college-based courses in ‘practical’ subject areas within a teacher education programme. Following three individual lectures (one each in art, music and physical education), pre-service teachers (n=11) participated in focus group interviews sharing their perspectives on the teaching and learning experiences. These data were analysed thematically and supported by teacher educators' (n=3) planning and reflection documentation. Although the problematic nature of the ‘practical’ suggests appeal and peril of the ‘practical’, the important nature of negotiating the ‘practical’ to enhance student learning is apparent. Students emphasised the value of practical engagement and expressed a strong preference for working in groups to create a safe learning environment to develop confidence and competence. These insights suggest key aspects of a pedagogy of teacher education in these ‘practical’ areas. The importance of being aware of and, in some cases, challenging student perspectives on how they learn best in these curricular areas is discussed.  相似文献   

Active recovery of the finger flexors enhances intermittent handgrip performance in rock climbers     

Jiří Baláš  David Giles  Jan Kodejška  Michaela Panáčková  Simon Fryer 《European Journal of Sport Science》2016,16(7):764-772

This study aimed to (1) evaluate the effect of hand shaking during recovery phases of intermittent testing on the time–force characteristics of performance and muscle oxygenation, and (2) assess inter-individual variability in the time to achieve the target force during intermittent testing in rock climbers. Twenty-two participants undertook three finger flexor endurance tests at 60% of their maximal voluntary contraction until failure. Performances of a sustained contraction and two intermittent contractions, each with different recovery strategies, were analysed by time–force parameters and near-infrared spectroscopy. Recovery with shaking of the forearm beside the body led to a significantly greater intermittent test time (↑ 22%, P?P?P?相似文献   

Visions of educational development in the post-socialist era     

Jiří Kotásek 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》1993,39(6):473-487

The paper attempts to characterize and explain the social, political and economic climate underlying educational dilemmas and visions in Czechoslovakia and other Central European countries after the collapse of communist regimes. The new democracies are becoming huge laboratories of social and educational reform — issues of great importance to comparative education. The most urgent dilemma is whether to restore the pre-war educational system, or to follow the mainstream of educational development. Educational policy is also seeking to find a specific solution to a second dilemma: statism versus liberalism in organization, funding, structure and curriculum. The hindering factor is underestimation of the significance of educational policy in the global reform process. Finally, the author quotes Havel's vision of a new politics of education based on consciousness and self-recognition of mankind.

Zusammenfassung Dieser Artikel versucht, das soziale, politische und wirtschaftliche Klima zu charakterisieren und zu erklären, das den Schwierigkeiten und Vorstellungen im Bildungswesen der Tschechoslowakei und anderer zentraleuropäischer Länder nach dem Zusammenbruch der kommunistischen Regierungsformen zu Grunde liegt. Die neuen Demokratien entwickeln sich zu riesigen Laboratorien sozialer und erzieherischer Reform — Themen von großer Bedeutung für die vergleichende Erziehung. Das dringendste Problem ist die Frage, ob man das vor dem Krieg bestehende Bildungssystem wieder einführen oder der Hauptrichtung der bildungspolitischen Entwicklung folgen soll. Die Bildungspolitik sucht außerdem nach einer spezifischen Lösung für ein zweites Problem: Planwirtschaft kontra Liberalismus in Organisation, Finanzierung, Struktur und Curriculum. Störfaktor ist die Unterschätzung der Bedeutung einer Bildungspolitik im globalen Reformprozeß. Abschließend zitiert der Autor Havels Vision einer neuen Bildungspolitik, die auf Bewußtsein und Selbsterkennung der Menschheit basiert.

Résumé Cet article tente de caractériser et d'expliquer le climat social, politique et économique sous-jacent aux problèmes et aux visons de l'éducation en Tchécoslovaquie et dans d'autres pays d'Europe centrale après la chute des régimes communistes. Les nouvelles démocraties se transforment en d'énormes laboratoires de réforme sociale et éducative, questions qui sont toutes d'une grande importance pour l'éducation comparée. Le problème le plus urgent est de savoir si l'on doit restaurer le système éducatif d'avant la guerre ou si l'on doit suivre le courant majeur du développement de l'éducation. La politique éducative cherche aussi à apporter une solution spécifique à un deuxième problème, à savoir étatisme ou libéralisme dans l'organisation, le financement, la structure et les programmes d'étude. Le facteur qui fait obstacle est la sous-estimation de l'importance de la politique éducative dans le processus de réforme globale. Enfin, l'auteur cite la vision de Havel d'une nouvelle politique d'éducation fondée sur la conscience et la reconnaissance naturelle de l'humanité.

Questions to assess learning as a communicative routine for inclusion     

Órla Ní Bhroin 《British Journal of Special Education》2013,40(3):114-123

In the context of rapid policy transformation from segregation to inclusion in the education of children with special educational needs in Ireland, a study was conducted to investigate the interplay between policy and principles of inclusion, resource teachers' and class teachers' interpretations of this and the manner in which policy and principle is enacted in their practice. Based on nine resource teachers and nine class teachers each paired in a particular school, interviews to elicit teachers' interpretations combined with observations to document the detail of practice generated data from which nine case studies were crafted. Findings revealed that teachers' interpretations and constructions of inclusive practice are grounded in the central tenets of communicative routines, attunement and coherence‐fragmentation. As such, the pedagogical practices central to facilitating inclusion are as follows: teachers' use of questions to assess learning and mediated talk; transactional teaching–learning interactions contributing to transformational teaching‐learning episodes; and optimal interfacing of resource teachers and class teachers. This article, by Órla Ní Bhroin of St Patrick's College, Dublin City University, focuses on teachers' use of questioning to assess learning as a communicative routine for inclusion.  相似文献   

Return to play management after concussion in football: recommendations for team physicians     

Nina Feddermann-Demont  Dominik Straumann  Jiří Dvořák 《Journal of sports sciences》2014,32(13):1217-1228

Abstract

A concussion is a rare but potentially serious injury of football players. Thus, an immediate and valid diagnosis, estimate of severity and therapeutic management is required. To summarise the published information on management of concussion with respect to a safe return to play (RTP), a literature search was conducted. Current guidelines on concussion in sports and significant studies on concussion in football were analysed. After concussion, management and RTP decision should remain in the area of clinical judgement on an individualised basis according to the current international guidelines. If a concussion is suspected, the player should not be allowed to RTP the same day. The RTP programme should follow a gradual step-wise procedure. A concussed player should not RTP unless he/she is asymptomatic and the neurological and neuropsychological examinations are normal. Untimely RTP bears an increased risk of sustaining another more severe brain injury and repetitive brain injury of long-term sequelae. In football, the management of concussion should primarily follow the recommendations proposed by the Concussion in Sports Group. Information and education of players and their medical and coaching team help to protect the players’ health. Future studies on concussion should include validated and detailed information on RTP protocols.  相似文献   

A Layered Approach to Critical Friendship as a Means to Support Pedagogical Innovation in Pre-service Teacher Education     

Tim Fletcher  Déirdre Ní Chróinín  Mary O’Sullivan 《Studying Teacher Education》2016,12(3):302-319

In this article we describe and interpret how two distinct layers of critical friendship were used to support a pedagogical innovation in pre-service teacher education. The innovation, Learning about Meaningful Physical Education (LAMPE), focuses on ways to teach future teachers to foster meaningful experiences for learners in physical education. Critical friendship was applied in two ways: (1) the first two authors served as critical friends to each other as they taught their respective teacher education courses using LAMPE, and (2) the third author acted as a meta-critical friend, providing support for and critique of the first two authors’ development and enactment of the innovation. Over two years, data were gathered from reflective journal entries, emails, recorded Skype calls, and teaching observations. The two layers of critical friendship held significant benefits in advancing and supporting the development of the innovation while also contributing to the professional learning of all participants. Analysis of the first year’s data showed that we entered the critical friendship without thoroughly considering what we each hoped to give and take from the relationship or acknowledging the potential problems that might unfold. In the second year, guided by suggestions from our meta-critical friend, we took a more rigorous inquiry stance as critical friends, contributing contentious feedback and pushing each other beyond our personal and pedagogical comfort zones. This led to a noticeable improvement in our professional learning about teacher education practices and advanced the development of the LAMPE innovation.  相似文献   

The international epidemiology of child sexual abuse: A continuation of Finkelhor (1994)     

Noemí Pereda  Georgina Guilera  Maria Forns  Juana Gómez-Benito 《Child abuse & neglect》2009,33(6):331-342

ObjectiveThe purpose of this paper was to compare the prevalence rates of child sexual abuse reported by [Finkelhor, D. (1994). The international epidemiology of child sexual abuse. Child Abuse & Neglect, 18 (5), 409–417] with those found in recent publications in order to confirm the widespread prevalence of child sexual abuse.MethodsRelevant articles about prevalence of child sexual abuse were identified through searches of computerized databases and a handsearch of Child Abuse & Neglect and the Journal of Child Sexual Abuse.ResultsThirty-eight independent articles were identified, corresponding to 39 prevalence studies; these articles report the prevalence of childhood sexual abuse in 21 different countries, ranging from 0 to 53% for women and 0 to 60% for men.ConclusionsComparison of the present study with that of [Finkelhor, D. (1994). The international epidemiology of child sexual abuse. Child Abuse & Neglect, 18 (5), 409–417] shows a similarity between prevalence distributions; there appears to be a general pattern that remains more or less constant over the years, especially in women.Practice implicationsTwelve years after the first revision study about the international prevalence of child sexual abuse, there is still a need for new data about this topic. The present study shows child sexual abuse is still a widespread problem in the society. In this research, carried out on 38 independent studies, there is new data for 21 countries over the world, being especially relevant the results obtained from other countries different from those pertaining to North America or Europe. It is important to point out the high prevalence found in most of the countries, so this information could be a new warning to make society and governments aware of this problem and undertake actions to prevent sexual abuse in childhood.  相似文献   

Reliability and Validity of Finger Strength and Endurance Measurements in Rock Climbing     

Michail Lubomirov Michailov  Jiří Baláš  Stoyan Kolev Tanev  Hristo Stoyanov Andonov  Jan Kodejška  Lee Brown 《Research quarterly for exercise and sport》2018,89(2):246-254

Purpose: An advanced system for the assessment of climbing-specific performance was developed and used to: (a) investigate the effect of arm fixation (AF) on construct validity evidence and reliability of climbing-specific finger-strength measurement; (b) assess reliability of finger-strength and endurance measurements; and (c) evaluate the relationship between finger flexor all-out test scores and climbing ability. Methods: To determine the effect of AF, 22 male climbers performed 2 maximal strength and all-out tests with AF (shoulder and elbow flexed at 90°) and without AF (shoulder flexed at 180° and elbow fully extended). To determine reliability, 9 male climbers completed 2 maximal strength tests with and without AF and an all-out and intermittent test without AF. Results: The maximal strength test without AF more strongly determined climbing ability than the test with AF (r² = .48 and r² = .42 for sport climbing; r² = .66 and r² = .42 for bouldering, respectively). Force and time variables were highly reliable; the rate of force development and fatigue index had moderate and low reliability. The maximal strength test with AF provided slightly higher reliability than without AF (intraclass correlation coefficient [ICC] = 0.94, ICC = 0.88, respectively). However, smaller maximal forces were achieved during AF (484 ± 112 N) than without AF (546 ± 132 N). All-out test average force had sufficiently high reliability (ICC = 0.92) and a relationship to sport climbing (r² = .42) and bouldering ability (r² = .58). Conclusion: Finger strength and endurance measurements provided sufficient construct validity evidence and high reliability for time and force parameters. Arm fixation provides more reliable results; however, the position without AF is recommended as it is more related to climbing ability.  相似文献   

Why Do Historical Beeswax Seals Become Brittle Over Time?     

Benjamin Bartl  Martin Zapletal  Štěpán Urbánek  Monika Krejčí Slavíková  Jiří Trejbal  Zdeněk Hrdlička 《文物保护研究》2013,58(3):138-145

ABSTRACT

Mechanical properties of aged beeswax were studied by an indirect measurement, using hydrogenated beeswax as a model material. The adequacy of the model was evaluated by comparison of its chemical composition and thermal properties with those of samples of historical beeswax. It was found that the gradual decrease in content of unsaturated compounds in beeswax contributes significantly to changes of its mechanical properties. As a consequence, beeswax artefacts become increasingly prone to mechanical damage during natural ageing. Understanding the difference between mechanical properties of recent and historical beeswax is primarily important from the point of view of safe handling and storage of such artefacts. Besides, this knowledge could help conservation scientists, e. g. when preparing model samples for testing new conservation methods.  相似文献   

Teacher professional development through collaborative action research: impact on foreign English-language teaching and learning     

Dario Banegas  Anahí Pavese  Aurelia Velázquez  Sandra María Vélez 《Educational Action Research》2013,21(2):185-201

In 2011 we, a group of English-as-a-foreign-language teachers at a secondary school in Argentina, decided to investigate our teaching practices through collaborative action research so as to improve our students’ learning opportunities and thus revitalise English-language teaching in our context. We implemented and evaluated the integration of content and language learning in our classrooms through the development of our own materials. The experience revealed a growth in professional development and how our motivation and autonomy influenced our students’ motivation and language development. In our attempt to disseminate our experience as a group, this report particularly focuses on the evaluation facets of our collaborative action research project so as to encourage other teachers and teacher-researchers to adopt collaborative action research to improve their own practices.  相似文献
