Curriculum mapping is a procedure for reviewing the operational curriculum as it is entered into an electronic database at any education setting. It is based largely on the work of Heidi Hayes Jacobs in Mapping the Big Picture: Integrating Curriculum and Assessment K-12 (ASCD, 1997) and Getting Results with Curriculum Mapping (2004, ASCD). Schools are using curriculum templates that display key components of the curriculum: content, skills, assessments, and essential questions.
