浅析德国大学特色教学法

德国的教育严谨中不乏创新。本文根据笔者在德国的学习经验归纳了德国大学教育中几项富有成效的教学法,并将它与课堂教学案例相结合,分析了这些教学法的不同应用背景和特殊教学模式,总结了它们的成功经验。同时,提出了如何在水文地质与环境专业教学实践中合理的应用这些教学方法。     

The mathematical discourse of 13-year-old partnered problem solving and its relation to the mathematics that emerges

This paper, written within a discursive perspective, explores the co-shaping of public and private discourse, and some of the circumstances under which one occasions the other, in the evolution of mathematical thinking by pairs of 13-year-olds. The discourse of six pairs of students, engaged in interpreting and graphing problem situations involving rational functions, was analyzed by means of recently developed methodological tools. The nature of the mathematics that emerged for each pair was found to be related to several factors that included the characteristics of the interpersonal object-level utterances both before and after the solution path had been generated, the degree of activity of the personal channels of the interlocutors, and the extent to which the thoughts of participants were made explicit in the public discourse. The analysis of the discursive interactions provided evidence that adolescents within novel problem situations can experience some difficulty in making their emergent thinking available to their partners in such a way that the interaction be highly mathematically productive for both of them.

Developing methods to evaluate web usability with people with learning difficulties

Use of the Internet and other forms of information and communications technology (ICT) by people with learning difficulties has not been extensively researched. This article by Peter Williams of the Rix Centre at the University of East London reports some of the findings from 'Project @pple', a major ESRC-funded programme exploring the ways in which people with learning difficulties access and use information and communication technologies. Using observations, interviews and formal usability tests, project researchers built up a multi-layered view of computer use, Internet access and interaction with software among people with learning difficulties. A number of key themes emerged, including the nature of the tasks encountered, engagement, relevance to needs and the role of supporters. Peter Williams summarises these issues and indicates avenues for the future development of targeted products and for further research.     

Fostering communication and shared play between mainstream peers and children with autism: approaches, outcomes and experiences

More pupils with autism are now being educated in mainstream settings and inevitably there is increased interest in their interactions with their peers. In this article, Philip Whitaker, of the Educational Psychology Service in Northamptonshire, describes his study of shared play between children with autism and their mainstream peers. The study involved ten youngsters with severe autism, educated in a unit attached to a mainstream school, and a group of volunteer 'peer tutors'. The children met in weekly interaction sessions designed to promote shared play and communication. The peer tutors were provided with some coaching in interaction techniques and the impact of the intervention was evaluated through analysis of video recordings of play sessions made at the beginning and end of the project. The peer tutors and their parents were also interviewed at the end of the project to explore their experiences.
The results Philip Whitaker reports are encouraging. All parents were strongly supportive of their children's participation. All but one of the peer tutors found the experience challenging but rewarding and wanted to continue their involvement beyond the 20-week project. The video evidence revealed that the peer tutors, with relatively limited preparation, were able to engage the youngsters with autism in high and sustained levels of shared play. The frequency of requesting by children with autism increased substantially over the course of the project, although levels of initiation of shared attention remained consistently low. Philip Whitaker concludes his report with a series of suggestions for enhancing the impact of this interesting work.
