The change from a student role to a teacher role can be one of the most abrupt and stressful transitions in working life but the process of socialization does not end when the student becomes a fully qualified teacher, as many writers, laymen and sociologists, would have us believe. Colin Lacey argues that socialization is a partial and rarely homogenous process. He illustrates this from a wide variety of interesting case material to show how student teachers adapt their responses to the classroom situation.
