The document discusses three types of curriculum: the formal curriculum that is officially documented, the informal curriculum involving a teacher's personality and interactions, and the hidden curriculum of unrecognized lessons. It also distinguishes between the written, supported, taught, and tested aspects of curriculum. Current issues discussed include curriculum clutter, the influence of testing on teaching, and the need for alignment between written, taught and tested curriculum. Site-based management and teacher autonomy are also examined in relation to curriculum development and implementation.
