The document discusses the different types of curriculum in an educational setting. There are four main types: the explicit curriculum which are the planned subjects taught; the implicit curriculum which are the cultural lessons learned from the school; the null curriculum which are topics intentionally excluded; and the extra curriculum which are supplemental programs. The curriculum aims to prepare students for society by transmitting its values through both academic and extra-curricular activities, as well as through hidden social lessons. The purpose, components, and influences on the curriculum are also examined.
