Definition of Curriculum

What is curriculum?  To be honest, I feel rather unqualified to voice my own definition yet--I feel as though I have so much to learn!  But in general, I think a curriculum is a structured plan used to pass knowledge and skills onto students.  In essence, I view curriculum as a blueprint with an end result: student acquisition of skills and/or knowledge base.  I think that some curricula are more structured that others, but the end result (should be) the improved knowledge of students.
