Research and Impact

The Interactive Mathematics Program (IMP) is the collaborative effort of mathematicians, teacher-educators, and teachers working together since 1989. Developed with support from the National Science Foundation (NSF)1 and other funding agencies, the IMP first edition was published after more than 10 years of research, pilot testing, evaluating, field testing, revising, and detailed reviewing. The IMP authors drew on contemporary research about how students learn and developed a program that would offer students multiple ways to learn mathematics in a problem-solving context. Several long-term studies of student performance and participation show that the IMP curriculum improves students’ learning and increases their study of advanced mathematics.
