Understanding technology: the development of a concept     

Tina Jarvis  Léonie J. Rennie 《International Journal of Science Education》2013,35(8):977-992

Children's perceptions about technology were measured using a Writing/Drawing Activity and a Picture Quiz, administered to approximately 300 grade three to six children in six primary schools in the English Midlands. The results indicate that although many children associate technology only with computers and modern appliances, overall there is a variety of ideas, with the more complex and coherent among older children. Subsequently interviews were carried out with 81 of the children to explore their reasons for choosing items which they said were something to do with technology. The children were able to respond in a thoughtful and consistent manner. Even when the children professed not to know what technology is, they often used an alternative but consistent explanation. A tentative model describing the development of children's ideas about technology is presented.  相似文献

Are we promoting critical autonomous thinking? A discussion on conversational genres and whether they can help us answer this question     

Andrés Mejía  Adriana Molina 《Cambridge Journal of Education》2007,37(3):409-426

This work is based on the assumption that if the classroom is a space in which manifestations of critical autonomous thinking appear systematically, then it promotes that same kind of thinking by the students, in other contexts. But what count as manifestations of critical autonomous thinking, and how can we observe them? As Robert Young's Habermasian work on indoctrination and conversational genres seemed a promising conceptual framework for understanding classroom situations in this respect, we took it as a starting point for exploring answers to these questions. Our exploration, both through fieldwork and theoretical reflection, led us to some findings, among which are (1) the existence of new genres which refine the conceptual categories originally formulated by Young; (2) that analysis of function is not enough, requiring also a contents dimension with which one can study what critical autonomous thinking is promoted about, in particular classroom situations; and (3) that classroom situations can be more contradictory and fragmented than presupposed by the very idea of genre.  相似文献

Three-dimensional kinematics of the lower limbs during forward ice hockey skating   总被引：1，自引：0，他引：1  

Upjohn T  Turcotte R  Pearsall DJ  Loh J 《Sports biomechanics / International Society of Biomechanics in Sports》2008,7(2):206-221

The objectives of the study were to describe lower limb kinematics in three dimensions during the forward skating stride in hockey players and to contrast skating techniques between low- and high-calibre skaters. Participant motions were recorded with four synchronized digital video cameras while wearing reflective marker triads on the thighs, shanks, and skates. Participants skated on a specialized treadmill with a polyethylene slat bed at a self-selected speed for 1 min. Each participant completed three 1-min skating trials separated by 5 min of rest. Joint and limb segment angles were calculated within the local (anatomical) and global reference planes. Similar gross movement patterns and stride rates were observed; however, high-calibre participants showed a greater range and rate of joint motion in both the sagittal and frontal planes, contributing to greater stride length for high-calibre players. Furthermore, consequent postural differences led to greater lateral excursion during the power stroke in high-calibre skaters. In conclusion, specific kinematic differences in both joint and limb segment angle movement patterns were observed between low- and high-calibre skaters.  相似文献   

Sleep management and the performance of eight sailors in the Tour de France à la voile yacht race     

Léger D  Elbaz M  Raffray T  Metlaine A  Bayon V  Duforez F 《Journal of sports sciences》2008,26(1):21-28

We observed how sailors manage their sleep and alertness before and during competition in a long-haul yacht race. Global performance of the teams was also recorded. We assessed eight sailors aged 21-30 years, split into four teams, who competed in the Tour de France à la Voile 2002 yacht race. Two phases of the race were examined: two legs in both the Atlantic Ocean and Mediterranean Sea. Sleep length, sleep debt, and sleepiness before competition and on board during the race were assessed using ambulatory polysomnography. Intermediate and final rankings were considered as a reflection of performance. A significant correlation was observed between the sleep debt before competition and the total sleep time on board during the Atlantic legs. The greater the sleep debt, the more sleepy the participants were. During the Mediterranean legs, almost all the sailors were deprived of sleep and slept during the daytime competitions. We observed that the final ranking in the race related to the sleep management strategy of the participants. In extreme competitive conditions, the effect of a good night's sleep before competition on performance is important. The strategy of the winners was to get sufficient sleep before each leg so as to be the most alert and efficient during the race.  相似文献

Questioning a tradition: A French way of excellence     

André Béraud 《European Journal of Engineering Education》2000,25(4):369-375

The following article was written in French as a keynote speech at the IGIP Symposiumat the Biel School of Engineering (University of Applied Sciences, in Biel, Switzerland), held in March 2000. The topic of this symposium was 'Unique and Excellent'. It aimed to show that engineering education cannot really head towards unification, but will reach uniqueness and excellency if there are many different ways of educating engineers. What happens on the spot, in each technical university, in each course, is much more important for excellence than the fact that all curricula can be compared directly at an international level. Owing to the very particular way of educating engineers in France, it was considered most important to learn about this particular organization. André Béraud accepted presenting it to the audience. His contribution had a very lively echo. The text presents a short outline of the history of French engineering education and its very particular ways and means. Engineering is not taught at technical universities but at Grandes Ecoles (Grand Schools), which represent a very high level of education open only to the very best. They will form the élite of the public servants of France, much more than what is generally considered the task of an engineer. In consequence, the education is broadly based with humanities as an important element in it; it is also very scientific, with mathematics and theoretical physics as central topics. The disadvantage of such a system lies in the fact that it is most rigid, not very open to the needs of industry and of foreign students. There have been, however, some changes.  相似文献
