A significant amount of research has been devoted to class size, in relation to student achievement. Success in the classroom is not only about increases in attainment. Fulfilment, and well-being, for teachers and students alike, is a more complete evaluation of improved achievement. The cost of reducing class sizes seems to be prohibitive, so teachers have adopted numerous strategies to cope with the increased numbers of students and their diversity. Teachers use educational assistants, resource teachers, specialized liaison assistants, and modern technology adapted for the classroom. Current research suggests that the use of subdued lighting and music can increase student focus. Innovative storage systems reduce congestion. Successful teachers use a combination of these strategies to reduce their own stress and to contribute to the overall achievement of all students in the classroom.
