Curricula is simply the plural of 'curriculum' — a curriculum is the full list of subjects and topics that a school or course teaches. So if you're talking about the school programs of several different schools together, you'd say 'their curricula.' In everyday speech, many people just say 'curriculums' instead — both are accepted, but 'curricula' is the older, more formal Latin plural, common in academic writing.
