The Role of Idealization in Science and Its Implications for Science Education

摘要: The main objective of this article is to study the role empirical evidence in interpretation psychological and epistemological aspects Piagetian theory. According Galilean methodology, after having asked right question, a scientist could experimentally vary one impediment, observe what happens dependent variable, as it approaches ideal limiting case. Following Galileo's idealization, scientific laws being constructions do not describe behavior actual bodies. It plausible suggest that just law can be observed only when all impediment variables approach zero, similarly individuals real world have various `impediments' these impediments are gradually removed by experimental manipulation performance approximate competence Piaget's epistemic subject (ideal knower). Finally, presented effect manipulating (e.g., Pascual-Leone's M-demand Witkin's perceptual field task), subjects approximates subject, which leads construction neo-Piagetian
