Handbook of Curriculum Development [PDF ebook] 

Curriculum Development can be defined as the systematic planning of what is taught and learned in schools as reflected in courses of study and school programs. These curricula are embodied in official documents (typically curriculum "guides" for teachers) and made mandatory by provincial and territorial departments of education. The primary focus of a curriculum is on what is to be taught and when, leaving to the teaching profession decisions as to how this should be done.
