This monograph addresses the following questions: What is MCM and how is it viewed by teachers and student-teachers? What are the methodological tools that could help improve classroom management competencies on an ongoing basis? How has the model proposed here been applied to various issues – the diversity of children in preschools, coping with challenging behaviour (and applying boundaries and rules), planning and implementing curriculum that promotes participation and learning? What improved or changed in the preschools following implementation of the MCM model? What are the main lessons learned about enhancing teachers’ classroom management competencies derived from applying the proposed model? Part I describes a theoretical model that defines MCM as a meta-competency. This theoretical model serves as a conceptual foundation for understanding interventions in educational settings that are focused on the enhancement and improvement of classroom management competencies. In the second chapter of Part I, we define the research methodologies employed by student-teachers and teachers in their attempts to understand the educational setting and improve their classroom management practice – an analysis of social episodes, action research, and case studies. The subsequent chapters provide an analysis and interpretation of cases showing employment of the MCM model by student-teachers and teachers in several main areas of preschool work. Part II looks at the application of the MCM model in dealing with children’s challenging behaviour. Part III examines MCM’s influence on curriculum and discourse that promotes learning. Finally, Part IV analyses the role of MCM in understanding and coping with diversity (ethnic, functional, and other). Collaboration with staff and parents as well as time and space management are embedded in the various domains of preschool work, and as such are indirectly addressed in Parts II, III and IV and summarised in the concluding chapter.
