A survey of educational trends at the elementary and secondary school level in countries throughout the world is summarized. Information was obtained from questionnaires sent to 30 pedagogic research organizations and from UNESCO reports and publications. The introduction discusses the universality of campaigns against illiteracy, expansion of primary schooling, increased accessibility of secondary education, improved teacher training, and improved educational organization. Differences are noted as occurring in subject matter, depending on the political, social, and economic factors of each country. Following the introduction, specific sections deal with the teaching of languages, mathematics, natural sciences, human sciences, art, music, and physical education. Each section describes important changes and the diversity of teaching methods in general, then discusses trends at the elementary and secondary levels. Next, a section on the emergence of trends between 1970 and 1980 points to common emphases in both developed and developing nations: an increased emphasis on preparing students for the working world and an interdisciplinary approach aimed at helping students understand world problems. The conclusion draws distinctions between developing and developed nations and notes that the primary concern of developing nations is the reacquisition of culture and a native language. (KC)
