| Abstract: | Interpersonal discussions and mediated exchange are combined processes in curriculum planning and innovation in the national project PING, a system for the development and evaluation of integrated science education in lower secondary schools in Germany. In this project teachers from pilot schools, researchers, teacher trainers and administrators are collaborating by direct interpersonal exchange in teacher training sessions, workshops and research meetings, or through mediated exchange by mail or electronic network. Collaboration is supported by institutionalisation and co-ordination with the aim of curriculum development for integrated science teaching. A major activity in the project is the reflective development and research activity of a core group, supported by a collaborative network. Analysis of interviews and network activities specify functions and problems of mediated exchange. The network is experienced as helpful for a continuous development in the project, especially through documentation and revision of a knowledge base of something already thought or discussed. The format is dependent on a co-ordination centre that offers exchange of messages, files and announcements. There is no direct mediated exchange between participants of the network. Mediated exchange is not a substitute for interpersonal contacts, especially of colleagues, and does not help to overcome teachers' individualistic role in class. However, it is socially less constrained by rivalries and unequal workload than interpersonal co-operation. Interpersonal and mediated reflective collaboration depends on a system of exchange between different persons across different institutions involved in a social and cultural context. Teachers are part of this exchange. In class, reflective practice refers to a situation where teachers mainly depend on their 'autonomous self'. At this point, teachers lack support from others and this lack is a conceptual problem of the individualistic reflective practice approach. |
