Today, on the eve of the 21st century, Japan is becoming an internationalized, information centered civilization. The sophistication of modern science and technology will create a demand for people who are highly productive in handling knowledge and sensitive in their manipulation of it. This advance of science and technology will also require an examination of life styles and the recovery of human dignity. The purpose of this report is to describe and discuss the characteristics of school science curriculum, which is now under revision in Japan, with relation to the science-technology-society (STS) theme. The present status of school science curriculum is examined in terms of its aims and objectives, scope and sequence, time allocation for teaching, and attained curriculum based on student assessment. After strengths and weaknesses of the present school science curriculum are assessed, and future needs identified, the major trends in reforming the school science curriculum at elementary and secondary school levels are described and analyzed in terms of the inclusion of the STS theme within the curriculum.
