This longitudinal study investigated four secondary social studies teachers, who identified as being constructivist teachers, during their student teaching practicum through their first year of teaching in the classroom. Specifically, this study focused on the relationship between the teachers’ constructivist-oriented beliefs and their use of related practices in their history classrooms. The findings showed that issues of classroom control were major barriers for the implementation of constructivist-oriented practices. Furthermore, the analysis showed that the participants had a limited development of practical tools. The author argues that although their teacher preparation program exposed them to many different types of instructional techniques and their methods course included the teaching of a model lesson to the class, the participants desired more practical tools as they entered their first year.
