The UNESCO Regional Office for Education in Asia conducted a survey to determine the trends in secondary school curriculum in Asia, including Afghanistan, Burma, Cambodia, Ceylon, China (Twaiwan), India, Indonesia, Iran, Japan, Korea, Laos, Malaysia, Mongolia, Nepal, Pakistan, Philippines, Singapore, Thailand, and Viet-Nam. The information collected revealed the following: (1) secondary education was assuming more importance due to the rising rate of enrollment in the primary schools; (2) since the developing countries of Asia were still basically rural, they were adapting curriculum, which was developed in an urban environment, to the needs of the country; (3) more time was being allocated for science and mathematics than for other subjects; and (4) basic research on curriculum development had not yet been developed on an adequate scale in these nations. Tables on regional enrollment and curriculum and on subjects of secondary school curriculum in each of these countries are included. (RH)
