Abstract:The mechanisms underlying class differentiation in educational choice have long been framed within two paradigms: cultural reproduction and rational choice. Empirical research has shown that the theory of cultural reproduction tends to hold a relatively dominant position. This paper reviews the historical debate between these two paradigms, emphasizing whether the mechanisms of educational choice and class differentiation are primarily driven by rational or non-rational factors. Through a comparative analysis of the strengths and weaknesses of both paradigms, it becomes evident that each, in isolation, offers limited explanatory power. Therefore, an integration of the two paradigms is both possible and necessary; however, an effective integration path remains lacking. Utilizing Simon's bounded rationality model, we propose a new integrated framework that combines elements from both paradigms. This bounded rationality model of educational choice provides a more robust theoretical tool for empirical research and offers valuable insights for the development of educational policy.
