The document discusses curriculum and the hidden curriculum. It provides definitions of curriculum from various sources that describe curriculum as comprising all planned learning experiences in and outside of school. It outlines principles of curriculum construction such as being child-centered, community-centered, balanced, needed-based, useful, creative, and contemporary. It notes major defects in current curriculums such as being exam-oriented, theory-focused, and not developing the whole personality. It defines hidden curriculum as unintended lessons learned from social environments and norms conveyed in school. It concludes that the current curriculum needs reorganization to align with curriculum principles and that hidden curriculums will always be present in schools to some degree.
