With science and technology playing profound roles in mediating human relationships with the environment, a key question concerns which expectations and views of science and technology have emerged and prevail in visions of the social and environmental development of contemporary societies. This study engages this question through examining children's views of science and technology in South Korea. Eighty-six sixth graders from Seoul, a highly urbanized city, were invited to share their views. A drawing and writing activity and an open-ended questionnaire were administered for data collection. The study found that the children's views are grounded in optimistic and positive expectations and visions of science and technology even as some of the children show awareness and concern about environmental destruction. They may also offer contradictory views toward social development and environmental destruction. The paper discusses these findings in light of the complex meanings of development in modern Korean society and the challenges teachers there may face in cultivating sustainable views and relations via science and environmental education.
