Increasing attention is being paid today to the place of science in general education at the preprimary, primary, and secondary levels. Educational authorities and specialists in many countries throughout the world agree about the important role that science should and can play in the context of education, but specific aims and objectives must be clarified and then translated into a set of educational activities. In May 1987, UNESCO organized an interregional workshop in Pyongyang, Democratic People's Republic of Korea, that focused on efforts to promote the dissemination of learning materials in preprimary, primary, and secondary curricula, and to develop national, regional, and interregional cooperation. The learning materials are intended to help children acquire scientific concepts and technical skills. This publication describes 40 materials, intended for kindergarten use, that were selected for exhibition at the workshop. The materials teach such skills as counting; collecting objects; tracing objects; distinguishing and naming colors; singing; matching numbers and words; making patterns; assembling objects and pictures; recognizing letters; matching numbers and geometric forms; and remembering. Each of the materials is illustrated with a color photograph, and the purpose, structure, and method of use are described. The materials exhibited at the workshop were produced in the Democratic People's Republic of Korea, the People's Republic of China, and Brazil. (BC)
