Despite lack of money and time, schools in the eighties are going to make changes. For this reason, educators are being forced to look again at the lessons of the innovations of the seventies. This paper discusses research done on those innovations, both the ones that succeeded and the ones that failed. A discussion of costs is followed by a summary of implications of research. The paper concludes that if educational innovation is going to succeed, educators will need to focus their work and time on communication, training, feedback mechanisms, and teacher support.
