The study reported in this paper intended to trace what Chinese children think about life and identify their naive theories. Fifty-eight 5-year-old children in Taiwan from 39 kindergartens were interviewed using a semi-structured instrument. Results indicate that preschool children have preconceptions about the concept of life even before entering elementary school. Some naive theories expressed by the students include movement theory, function theory, growth theory, organ theory, response theory, action theory, death theory, life-span theory, and myth theory. Most of the young children had developed conceptions of life concerning primary attributes such as movement, growth, reproduction, structure, and Function. Most of them had not developed the advanced attributes such as responsiveness, adaptation, life organization, energy translation and so forth. Contains 13 references and a list of 6 papers in Chinese. (Author/JRH)
