The way the system has been structured by those in power and the ways in which teachers are required to work within these prescribed boundaries are mainly at fault: the grouping, selective treatment of students, differential program streams, differential expectations, the large classes, the pressure on teachers to cover a standardized curriculum, the lack of opportunities and resources for teachers to offer innovative curricula, courses and programs to students, not to mention the multitude of regulations, policies and procedures that determine where and how teachers will carry out their duties. These factors, and many more, result mainly from conscious decisions made by administrators and politicians, not by teachers.
