The document discusses the need for curriculum planning and development in the Philippines given the changes in education over the past decades. Key developments include the Philippine Commission to Survey Philippine Education's recommendations in the 1970s that were adopted as policy changes. These included setting national development goals, establishing regional science centers, and upgrading agricultural education. Education must be dynamic and respond to societal challenges and needs. It aims to both transmit and modify cultural heritage while promoting human and societal development.
