This bulletin addresses the topic of out-of-school science education (OSSE) as it is occurring and developing in the countries of the Asia and Pacific region of Unesco. Out-of-school programs/activities are both complementary of and supplementary to science education in the schools, providing activities that the constraints of schooling usually exclude from the curriculum. The first section comprises an introduction to the concept, suggested approaches, and a review of strategies employed by 13 out of the 15 countries represented. The second section consists of individual reports from Australia, Bangladesh, China, Indonesia, Japan, Malaysia, Nepal, New Zealand, Pakistan, Philippines, Republic of Korea, Singapore, Socialist Republic of Vietnam, and Thailand. Areas addressed in these reports include science museums, science clubs, science fairs, and media use (television, radio, printed media). In addition, programs/activities unique to a given country are also discussed. These include the Science Foundation Programme (Philippines), Nature Conservation Association (Republic of Korea), Bangkok Planetarium (Thailand), and others. The final section consists of an annotated bibliography of out-of-school science education activities/programs. (JN)
