During the 1996 Teacher Enhancement Institute (TEI) on the campus of Saint Vincent College in Latrobe, Pennsylvania, a very diverse group of teachers actively pursued instructional improvement through workshops in thinking skills, content area, and group seminars for a period of 4 weeks. This report contains evidence of improved teaching skills in science, mathematics, and classroom techniques gathered through pretest and posttest instruments, and interviews with faculty and participants. Both cognitive and affective domains were targeted by the TEI. Participants indicated significant growth in both areas. A major contribution of the TEI to teachers was reported as being the dissemination of new materials brought to them by the Saint Vincent College staff and by their peers in the respective workshops. It was concluded that the TEI participants experienced a positive change in affective and cognitive behaviors and attitudes through the activities during the time of the institute. (JRH)
