The Blackwell Companion and Blackwell Guide to the philosophy of education, edited respectively by Randall Curren and by Nigel Blake, Paul Smeyers, Richard Smith and Paul Standish, are potentially field-defining volumes. The present essay moves back and forth between the two books to assess the overall impression they provide of the 'state of the art'. Whilst both texts can be criticised for failing to engage sufficiently with non-philosophical work on education, these are otherwise estimable volumes, containing many fine essays that can be read with profit. 相似文献

All those who compete in the sport of rowing have used the land rowing machine, Ergometer (commonly called the ‘erg’), manufactured
by Concept II (Morrisville, Vermont, USA). Ergon is the Greek word for work, hence the Ergometer measures work. Rowers are
commonly ranked according to their ‘erg score.’ The fault in this ranking is that the land Ergometer cannot account for many
of the important technical aspects associated with rowing on the water. The goals of this project were to (1) develop a system
for on-the-water measurement of work during rowing and then (2) demonstrate the potential of such a system to quantify performance
and improve rowing technique. To achieve these goals, force was measured using strain gauges glued to the shaft of the rowing
oar and angular displacement was measured using a potentiometer. The force and displacement measurements were sent to a microcontroller,
which calculated the total work done in a particular stroke, as well as other parameters, and displayed the values to the
rower. The parameters were used to evaluate the performance of three collegiate rowers on the water. The data were also used
to plot force profiles, which were reviewed with each rower and the coach to illustrate the rowers’ habits and facilitate
improving technique. One rower was ‘tutored’ with the device through five on-the-water practices, after which his force profiles
and parameter values demonstrated significant improvement. The device not only provided a standard to which all rowers were
compared on the water, but also supplied the rowers with important information on technical aspects of their strokes and pacing
themselves. 相似文献

This study reports on a very successful collaboration between teacher education courses in Manchester and Amsterdam and the Van Gogh Museum in Amsterdam. The central aim of the initiative was to promote and sustain partnerships between Higher Education (HE) institutions, public galleries and schools with a view to developing, delivering and sharing good practice in art and design within a European context. 相似文献
