Curriculum reform has been the major means for effecting educational change in developing countries. Much effort was made in the 1960s and 1970s to change the content of the curriculum in order to make it more relevant to individual and national needs, as many countries, especially, those newly independent tried to achieve development through education (Simmons, 1983). Many developing countries have expanded access to education by building more schools, and educating more teachers. With aid from international agencies, they have attempted to improve educational quality by providing more basic facilities such as furniture, textbooks and instructional materials.
