As the central part of a $1 million NSF-STEP grant (DUE-0969109), Bridgewater State University completely reorganized its teaching of all gateway science and math courses by utilizing changes in classroom pedagogy tied to a variety of forms of peer cooperative learning, of which supplemental instruction (SI) is an example. After briefly sharing the success of Bridgewater’s different departmental models, the facilitators will lead a workshop in which participants begin to plan or design course changes supported by SI for either new implementations or improved implementations.
