Student mobility and trans-national collaborative modes of learning at University level have been strongly promoted within Europe. However, such initiatives are expensive, difficult to organise and do not always attain their objectives. Recently there has been considerable interest in the extent to which computer-mediated communication between students in different countries can either supplement or substitute for actual student mobility. This paper reports an evaluation of a project in which video-conferencing was introduced in the context of an established Anglo-Spanish programme in which UK and Spanish Fashion students undertake collaborative projects in each others’ countries. Project aims included fostering and supporting second language use, providing an innovative context for collaborative art and design projects and offering an opportunity to simulate trans-national working conditions. Questionnaires, observation and interview data indicate that not all these objectives were realised, though student reaction to the technology and to the benefits it afforded for collaboration were broadly positive. The strengths and weaknesses of video-conferencing as a support to collaborative learning in this context are discussed.  相似文献

This study examines ways of approaching deductive reasoning of people involved in mathematics education and/or logic. The data source includes 21 individual semi-structured interviews. The data analysis reveals two different approaches. One approach refers to deductive reasoning as a systematic step-by-step manner for solving problems, both in mathematics and in other domains. The other approach emphasizes formal logic as the essence of the deductive inference, distinguishing between mathematics and other domains in the usability of deductive reasoning. The findings are interpreted in light of theory and practice.

The capacity of newborn infants to smooth-pursuit eye movements in single-target tracking and in optokinetic nystagmus to a moving striped field was examined utilizing DC electrooculography. Smooth-pursuit movements were observed in all infants who were alert during testing, but they occupied less than 15% of viewing time during single-target tracking. The velocity of smooth-pursuit segments in single-target tracking increased linearly to a target velocity of 19 degrees/sec and deteriorated rapidly at faster speeds. No smooth pursuit occurred above 32 degrees/sec in single-target tracking. By contrast, optokinetic nystagmus was observed at all field velocities to 40 degrees/sec, but the speed of the mean slow component increased linearly to 25 degrees/sec and diminished above that field velocity. Infant optokinetic nystagmus differed strikingly from that of adults in that tonic ocular deviation was in the direction of field movement rather than away from it. This feature of neonatal optokinetic nystagmus is consistent with deficient foveal function and suggests that the relatively poor smooth-pursuit performance of newborns may be related to foveal immaturity.  相似文献

那一年,我在云南省宣威市第六中学念高一。那时,父亲病逝刚满周年。母亲为了养活我和年幼的弟弟,在家对面的巷子里辟出了一间小屋,用来养猪。十几头日渐肥壮的白猪,在我的记忆中,如同一面面不停轮转的磨盘,将我悲苦的母亲团团围在中央。她只能无奈地站在那儿,任凭它们一口一口地吞噬她残剩的气力。  相似文献

The purpose of this study is to understand how preservice teachers experience a common university assignment: the videotaping and analysis of their own instruction. Using empirical data and the thought of the French philosophers Michel Foucault and Emmanuel Levinas, the study examines the difficulties in transitioning from student subjectivity to teacher subjectivity within the context of university-based teacher education. The paper ends by considering the role teacher educators can play in helping student teachers grow through their preservice experiences.  相似文献
