This study examined two research questions: (1) Is there any significant relationship between general departmental support and adoption of instructional innovations by faculty innovators at a large university? and (2) Is there any significant relationship between specific departmental support and adoption of instructional innovations by faculty innovators? The study employed a cross-sectional survey method. Subjects were all faculty members at Michigan State University who voluntarily developed and used instructional innovations in their departments. A 30-item structured questionnaire was used to gather data from 55 subjects. Pearson correlation was used to determine the relationship between general departmental support and adoption, while partial correlation was used to determine the relationship between departmental support and adoption. Findings indicate a significant relationship between general departmental support and adoption of innovations by faculty innovators. With regard to the second question, findings revealed significant relationships between office support and adoption, colleagues' support and adoption, and chairman's support and adoption. No significant relationships were found between financial support and adoption, policy support and adoption, and technical support and adoption. (GL)
