As new laws on education were gradually adopted in post-communist states after 1989, the countries also dealt with the problem of how to include home education in their own legislation. This article investigates the development of legislation on home education in five states of post-communist Central Europe: the Czech Republic, Slovakia, Slovenia, Poland and Hungary. This analysis of the legal environment for home education confirms on the one hand that these countries’ approach is similar in many aspects. Generally, laws tend to regulate home education rather strictly, all home-educated children must be enrolled at some school, and these schools are mandated by the state to serve as supervisory bodies for home-educated children. This legal arrangement puts the parents of home-schooled children in a very subordinate position in relation to the school. Despite these restrictions, however, the states have gradually opened up the option for home education to quite a broad pool of potentially interested people. On the other hand, the findings show that there are also significant differences between individual countries. These differences provide a good illustration of the fact that, despite historical, economic and cultural similarities, political institutions and state bureaucracies in individual states act autonomously, which leads to different policy outcomes.  相似文献

This paper analyzes the debates on “interracial competition” and “racial extinction” in the biological discourse on human evolution during the second half of the nineteenth century. Our intention is to discuss the ideological function of these biological concepts as tools for the naturalization and scientific legitimation of racial hierarchies during that period. We argue that the examination of these scientific discussions about race from a historical perspective can play the role of a critical platform for students and teachers to think about the role of science in current othering processes, such as those related to biomedical technosciences. If they learn how biological ideas played an ideological function concerning interracial relationships in the past, they can be compelled to ask which ideological functions the biological knowledge they are teaching and learning might play now. If this is properly balanced, they can eventually both value scientific knowledge for its contributions and have a critical appraisal of some of its implications. We propose, here, a number of initial design principles for the construction of teaching sequences about scientific racism and science-technology-society relationships, yet to be empirically tested by iterative cycles of implementation in basic education and teacher education classrooms.  相似文献

In teacher education and in physical education teacher education (PETE), the possibilities and pitfalls of critical pedagogy (CP) for transforming society have been frequently debated. From these debates, it has become quite clear that the lines separating ‘technocrats’ from ‘radicals’ are so strongly drawn that limit the advance of PETE. In the spirit of collegiality, we offer an alternative approach to CP based on Foucault's genealogical work on the History of Sexuality. It promotes a pedagogical perspective toward the development of ethics and the care of the self. We argue that this approach, far from discrediting what non-critical pedagogues do, can not only advance the practice of CP, but also open up new ways of conceptualizing PETE that are worth considering both by critical pedagogues and by the members of other pedagogical camps. We discuss the implications of this approach in the personal, social–professional and political spheres.  相似文献

The aim of this study was to analyse the kinematic sequencing in the penalty-corner drag-flicks of elite male and female field hockey players of international calibre. Thirteen participants (one skilled male drag-flicker and six male and six female elite players) participated in the study. An optoelectronic motion analysis system was used to capture the drag-flicks with six cameras, sampling at 250 Hz. Select ground reaction force parameters were obtained from a force platform which registered the last support of the front foot. Twenty trials were captured from each subject. Both player groups showed significantly (p < 0.05) smaller ball velocity at release, peak angular velocity of the pelvis, and negative and positive peak angular velocities of the stick than the skilled subject. Normalised ground reaction forces of the gender groups were also smaller than that of the skilled drag-flicker. By comparing these players we established that the cues of the skill level are a wide stance, a whipping action (rapid back lift) of the stick followed by an explosive sequential movement of the pelvis, upper trunk and stick.  相似文献

Optimal exercise performance in well trained athletes can be affected by arterial oxygen saturation failure. Noninvasive detection of this phenomenon when performing a routine ergometric test can be a valuable tool for subsequent planning of the athlete's training, recovery, and nutrition. Oximetry has been used to this end. The authors studied 339 athletes performing a similar exercise trial under well controlled environmental conditions. Maximum speed, oxygen uptake, and heart rate levels were simultaneously measured. From the obtained data, six patterns were found: (a) athletes in whom oxygen saturation is constant (≥ 95%) during test execution; (b) athletes displaying a progressive desaturation with incremental exercise intensities; (c) athletes presenting a transient desaturation in the anaerobic threshold region; (d) athletes starting with a mild-to-moderate desaturation at the beginning of the test, but reaching normal saturation values at the end; (e) athletes displaying mild-to-moderate desaturation levels throughout the whole test; and (f) athletes displaying a transient desaturation in the anaerobic threshold region and a new desaturation at the end of the test. In conclusion, it is believed that establishment of desaturation patterns by validated oximetry could be a first approach to evaluate the adaptation of the cardiorespiratory system to exercise intensity, helping to improve results.  相似文献

In this study, we analyzed the relationship between running economy (RE) and biomechanical parameters in a group running at the same relative intensity and same absolute velocity. Sixteen homogeneous male long-distance runners performed a test to determine RE at 4.4 m.s-1, corresponding to 11.1% below velocity at the ventilatory threshold. We found significant correlations between RE and biomechanical variables (vertical oscillation of the center of mass, stride frequency, stride length, balance time, relative stride length, range of elbow motion, internal knee, ankle angles at foot strike, and electromyographic activity of the semitendinosus and rectus femoris muscles). In conclusion, changes in running technique can influence RE and lead to improved running performance.  相似文献

Electronic government procurement (eGP) is quickly becoming an essential piece of national e-government programs, since it enables active transparency and favors efficient vendor relationships; however, little attention has been paid to the need for periodical measurement of eGP portals' performance and goal satisfaction. Although maturity levels schemes have been proposed for other domains, most notably IT-related, to the best of our knowledge no maturity level model of eGP has been widely deployed yet. This article presents the e-Government Procurement Observatory Maturity Model (eGPO-MM), which focuses on both legal and institutional arrangements, and portals' technical aspects; the model consists of two Leverage Domains, seven Key Domain Areas, and 25 Critical Variables, which are valued with a weighted scoring system that produces quantitative indicators about portal capabilities and allows direct comparisons. The model was used to evaluate eGP portals from 14 countries in Latin America and the Caribbean; the measurements are presented, and fit well with previous rank perception, leading to a good reception by participant agencies. eGPO-MM has already allowed to identify areas for joint action and fostered knowledge-sharing among governments, including identification and dissemination of e-procurement best practices; it also established clear reference points to allow each agency to determine a roadmap to higher e-procurement maturity.  相似文献

While a lot has been written regarding the changing management and governance arrangements in higher education, less is known about how this progression relates to quality in higher education. The purpose of this article is to describe the context of governance in Portuguese higher education institutions and how institutional governance arrangements impact on quality and quality assurance mechanisms of higher education. The study is based on four institutional cases studies, comprising two universities and two polytechnic institutions. Semi-structured interviews were conducted with senior managers, middle managers, academics and students from Arts and Engineering, and documentary analysis was undertaken. The main findings show that national and institutional features of governance and management may influence the implementation of quality policy and procedures, and indeed quality improvement. The different institutional actors seem to be aware of the dynamic nature of the equilibrium between positive and negative impacts and recognise the need for checks and balances in the governance and management structures of higher education institutions, especially between collegial and managerial facets.  相似文献

Abstract

The author presents a case for expanding the philosophical literacy of preservice teachers. It is argued here that increasing the philosophical literacy in teacher education programs will enable teachers to think deliberatively and, consequently, reflectively on the exigencies of their practice. For example, through guided experience with philosophy of education, preservice teachers can gain familiarity with the hermeneutics of inter‐subjectivity, thus making them better able to communicate and understand their own students and their families. The author uses John Dewey's pragmatic ideas about reflection, hermeneutics, and equity as examples of how philosophical literacy can guide preservice teachers’ professional contemplation.  相似文献
