This report is a formative evaluation of the use of an online listserv discussion group as part of a continuing project with schools exploring or implementing interdisciplinary teamed instruction (ITI). A survey was developed to identify member characteristics, what services were liked and used most, and what services were desired. Analysis of 59 completed surveys (out of 250 listserv subscribers) indicated respondents included educators in 29 states and 3 foreign countries with the majority (56 percent) being teachers. On a general level, the results supported the inclusion of cyberspace in the concept of professional community. Most respondents were local education agency staff who reported they were satisfied with the listserv services and used it frequently. Respondents also indicated strong interest in online education in ITI and the practical aspects of curriculum integration. The survey is appended. (JLS)
