The School Renewal Network, an interactive knowledge base on school reform, was created to provide opportunities for educational practitioners to have an audience for, make notations of, and reflect upon practical wisdom for the teaching culture. To appraise the network's effectiveness in meeting its goals and the nature of its interactions, data derived from all 1990 network computer log files as well as 34 of 40 surveys and 103 interviews with participants were analyzed. Findings indicated that a public and private audience does exist on the network; however, practitioners did not find the audience accessible or compelling enough to be useful for notations and reflections. Results also indicated that interactions needed to be wider and deeper with more feedback for the network to have an impact on its participants. Seven tables are used to illustrate data analysis. Appendices A through C contain the diagram of the network's organization, PSI-NET Conference and session structure, and survey of participating practitioners. (26 references) (EJS)
