This is the original network of superintendents, two are connected if the first recognizes the second as a good friend. This is a non-symmetric network.
A generalized version of this network is the Modern Math Methods network.
Background:
This network concerns the diffusion of a new mathematics method in the 1950s. This innovation was instigated by top mathematicians and sponsored by the National Science Foundation of the USA as well as the U.S. Department of Education. The diffusion process was successful since the new method was adopted in a relatively short period by most schools. The example traces the diffusion of the modern math method among school systems which combine elementary and secondary programs in Allegheny County (Pennsylvania, USA). All school superintendents who were at least two years in office were interviewed. They are the gatekeepers to educational innovation because they are in the position to make the final decision. The researchers obtained data from 61 out of 68 superintendents, 51 of whom had adopted by 1963 (84%). Among other things, the superintendents were asked to indicate their friendship ties with other superintendents in the county with the following question: Among the chief school administrators in Allegheny County, who are your three best friends? The researcher analyzed the friendship choices among the 38 interviewed superintendents who adopted the method and were in position at least one year before the first adoption, so they could have adopted earlier. Unfortunately, the researcher did not include the friendship choices by superintendents who did not receive any choices themselves; they are treated as isolates.
