MSU Research History: A New Way to Teach Math
1985 – Michigan State University educational researchers Glenda Lappan, Elizabeth Phillips, William Fitzgerald and Mary Winter, with support from National Science Foundation (NSF) professional development grants, develop an innovative new curriculum known as Middle Grades Mathematics Project (MGMP) materials. These materials were the precursor to the nationally recognized Connected Mathematics textbook series still used in 2015.
Connected Mathematics is a problem-centered curriculum designed to promote inquiry-based learning. The curriculum presents mathematical ideas in a sequenced set of tasks that helps students develop understanding and meaningful skills. The Common Core State Standards for Mathematics (CCSSM) and the Standards for Mathematical Practice are embedded within each problem.
