Using four IMPACT innovations as examples (EXPER SIM, Guided Design, TIPS, and Student-to-Student Counseling), this study attempts to define the nature of technological and social changes in university teaching. Data were gathered in three phases: (1) a questionnaire was mailed to individuals who requested information; (2) the adopters of innovations were interviewed; and (3) individuals who received second-hand information were interviewed. The results of the survey focused on the primary and secondary dispersion of information, the decision making mechanism used to determine when an innovation should be adopted, the extent of adoption, and the barriers to adoption. The text of the report describes in detail the research methodology and conclusions, and the appendixes provide definitions of concepts, informational brochures about the four innovations, sample questionnaires, and coding sheets for the interviews.
