This article includes two portions. The first portion outlines P. Jackson's perspective on hidden curriculum, according to his outstanding work " Life in the Classroom" (1968). I believe that his perspective has significant meanings to understand the adaptive problems fronted by the beginning pupils. The second portion discusses five questions that are drawn from Jackson's perspective. In these interpretations, I mainly apply E. Durkheim's and L. Kohberg's perspectives. These reflections primarily focus on two issues--classroom management and moral education.
