Structure of the Michigan Introductory Program Curriculum The syllabus stresses the underlying concepts and incorporates challenging real-world problems. The textbook emphasizes the need to understand problems numerically, graphically, and through English descriptions as well as by the traditional algebraic approach. Graphing calculators are used throughout the introductory courses. Instruction centered around interactive learning and student responsibility The classroom environment uses interactive learning and promotes experimentation by students A portion of each student's grade is based on solutions to interesting problems submitted jointly by teams of four students. Instructors grade the team's homework themselves. Restructured testing program Major exams can focus on concepts and critical thinking because there is a set of repeatable tests devoted exclusively to routine manipulative skills. Comprehensive faculty & graduate student instructor development program The fall term begins with an intensive training week followed by weekly teaching meetings and periodic classroom observations with feedback.  Teachers have access to a set of fully developed classroom activities.
