The development and dissemination of science materials can be associated with technical delivery systems such as the Unified Network for Informatics in Teacher Education (UNITE). The UNITE project was designed to investigate ways for using computer networking to improve communications and collaboration among university schools of education and K-12 schools. This paper describes computer networking strategies, for building collaboration, which evolved during the Integrative Network for Science Teaching Exploration and Practice (INSTEP) project. Several of the INSTEP strategies grew out of experiences from the ongoing UNITE project for investigating teacher support activities across a range of content specialties. Three integral networking components support the goals of this project: electronic mail, a curriculum navigator, and community published dynamic resources. A detailed description of each of these components is provided. Discussions on cross-school inquiry activities and initial observations are included. (KR)
