The Joint Impact of Block Scheduling and the Interactive Mathematics Program (IMP) Curriculum on High School Mathematics Achievement

Abstract

"This study investigated mathematics learning at a suburban United States high school that
simultaneously adopted a semestered (4 x 4) block schedule and the Interactive Mathematics
Program (IMP), a curriculum designed to implement the National Council of Teachers of
Mathematics (NCTM) Standards. Previous research has often found that at sites where a block
schedule was adopted without changes to mathematics curriculum and instruction, mathematics
achievement has declined. In contrast, when a semestered block schedule and the IMP
curriculum were implemented jointly, with extra time allocated to planning and staff
development, the two innovations were followed by improvements in student mathematics
achievement."
