Interactive Mathematics Program (IMP ) This Innovative Four-year Mathematics Program Reaches More Students-with More Math! Shaped by ten years of field testing, IMP is a full curriculum for college preparatory mathematics, created with backing from the National Science Foundation in response to a growing awareness of the need for mathematics instruction reform. The curriculum meets the needs of both college-bound students and those headed directly into the workforce, preparing them to use problem-solving skills both in school and on the job. More Than Just a Blending of Traditional Topics Departing radically from the traditional subject-by-subject mathematics curriculum, IMP employs an integrated approach that includes important topics that are not taught in a traditional curriculumtopics such as probability, statistical reasoning, and discrete mathematics. Its problem-centered approach helps students learn to think creatively and critically, and teaches them to draw simultaneously from many areas of mathematics to solve real-life problems. IMP fortifies students with a host of other life-enriching skills, ranging from working in groups to expressing ideas orally and in writing. Results show this revolutionary approach pays off. IMP improves the mathematics proficiency of a broad range of students and encourages many students to take more mathematics than they would originally planned. And their SAT scores prove to be equal to or better than those of their peers in traditional programs!
