This paper discusses the relationship between English language trainee teachers' views on how to deal with large classes at the primary school level, create a positive environment in young learners' classroom and hold young learners' attention, and how far their views are reflected in classroom practice. The data were collected by means of questionnaires, tutor logs, discussions (development sessions) and classroom observations over one and a half academic year. The questionnaires shed light on the views of trainees on how to deal with three discipline problems. In their fourth year, trainees systematically wrote tutor logs about their strengths and weaknesses in dealing with these discipline problems and discussed their logs with the researcher at weekly scheduled discussion sessions. Classroom practices were observed by the mentor and researcher at placement schools. The data show that the more teaching experience a trainee has the better his/her views are reflected in classroom practice. (Contains 5 tables.)
