Besides explaining the material herself, the chapter discussed about curriculum organization. The term of curriculum organization could be defined as the elements those could be inserted in arranging curriculum. There are some basic structures in curriculums organization like content structures including discrete or flat, hierarchical, linear, and spiral. Another structure is media structure including parallel, convergent, divergent, and mixed. There are also organizational principle like subject material, learners and learning, teacher and teaching, milieu which is divided into social, economic, political, organizational and physical. And actually I do not understand in some pert of this chapter like the three parts I have mentioned in the previous paragraph. I got 75 percent of understanding from this chapter.
