Problems in Teaching Philosophy of Education

Those of us who teach philosophy of education can hardly be happy with the present state of our subject. On many counts now the energetic optimism of a decade or two ago just seems misplaced. Of course there have been considerable achievements, but much is wrong and badly wrong. The abundance, diversity and quality of literature that marks a healthy discipline is not yet in evidence, educational leaders and top decision makers take little heed of philosophical counsel, eminent educational philosophers are questioning the place of theoretical disciplines in teacher education, declining members of philosophy of education societies seem to reflect declining career prospects, and political developments in some countries are reflected in educational administrations that set little value on liberal studies, independent though and philosophy

An Idea to Save Educational Theory

The future looks gloomy for educational theory. The place of theory in the education of teachers and in deliberations on educational policy, is being speedily reduced. The number of persons employed to teach educational theory is declining and many of those who remain are having to teach adulterated or dubiously \u27relevant\u27 theory regarding which they can feel no real enthusiasm or honest commitment. It is possible that some areas of educational theory which have developed impressively over the last two or three decades will almost vanish. Already one can discern the unhappy consequences for practice. Thus a valuable contribution to this year\u27s PESA conference was Robin Barrow\u27s attack on \u27the Genetic Fallacy\u27 in education - on the notion that it is possible, let alone meaningful, for educators to set about developing generic abilities and capacities of mind, such as critical thinking skills or reasoning abilities. Barrow\u27s talk was timely and left little room for doubt as to the highly questionable nature of many contemporary curriculum developments. His critique is urgently needed. Yet it ought not to be. For a quarter of a century ago a central plank in Paul Hirst\u27s \u27Forms of Knowledge\u27 thesis was that it only made sense to talk of abilities and powers of the mind within specific contexts such as those provided by the disciplines of knowledge. Compatible conclusions had long been emerging from psychological work on transfer of training. Of course an educational innovator might study such views and discern grounds for rejecting them. Yet recent \u27thinking skills\u27 talk seems to be in ignorance rather than informed denial of these bodies of theorising. So sweeping reforms of practice are being introduced by people who seem to be unaware of good theoretical inquiries which suggest that their reforms may be mistaken and damaging, and give helpful pointers as to how they might be improved

Properties of simulated sunspot umbral dots

Realistic 3D radiative MHD simulations reveal the magneto-convective processes underlying the formation of the photospheric fine structure of sunspots, including penumbral filaments and umbral dots. Here we provide results from a statistical analysis of simulated umbral dots and compare them with reports from high-resolution observations. A multi-level segmentation and tracking algorithm has been used to isolate the bright structures in synthetic bolometric and continuum brightness images. Areas, brightness, and lifetimes of the resulting set of umbral dots are found to be correlated: larger umbral dots tend to be brighter and live longer. The magnetic field strength and velocity structure of umbral dots on surfaces of constant optical depth in the continuum at 630 nm indicate that the strong field reduction and high velocities in the upper parts of the upflow plumes underlying umbral dots are largely hidden from spectro-polarimetric observations. The properties of the simulated umbral dots are generally consistent with the results of recent high-resolution observations. However, the observed population of small, short-lived umbral dots is not reproduced by the simulations, possibly owing to insufficient spatial resolution.Comment: Accepted for publication in A&

Seguidilla und Mantilla - das Spanienbild im Libretto von opéra-comique und opéra-bouffe:Untersuchungen an Hand von ausgewählten Librettotexten des 19. Jahrhunderts

Die als Folge der Romantik auftretende Mode der couleur locale und des Exotismus prägt das Kunstschaffen des 19. Jahrhunderts, so auch die populäre, typisch französische Unterhaltungsform jener Zeit, die opéra-comique bzw. – nach 1850 – die sich daraus entwickelnde opéra-bouffe. Die vorliegende Untersuchung konzentriert sich auf die hispanistisch inspirierten Librettotexte dieser Opernform und stellt deren Libretti als sorgfältig komponierte Intrigenkomödien heraus, die das noch unbekannte Spanien darstellen, indem sie zentrale Epochen der spanischen Geschichte und typisch spanische Charakterzüge aufgreifen. Nach 1850 trägt die Kritik an Missständen in der französischen Gesellschaft häufig spanische Verkleidung. Das daraus entstehende Spanienbild ist ein Amalgam von Realitätsbezügen und Klischees, deren Kern jedoch authentisch ist. Zusammen mit der gezielt eingesetzten, spanisch klingenden Musik entsteht ein Unterhaltungstheater, das jedoch auf spanischem Boden nicht nur Zustimmung findet.<br
