The most important factor resisting curriculum change is Teachers. Teachers are the primary implementers of any curriculum. Their established routines, comfort with existing materials, potential lack of training for new approaches, or skepticism about the benefits of change can create significant inertia. Without their active buy-in and participation, curriculum reforms often struggle to be effectively implemented. While aristocratic classes, political leaders, and parents can influence curriculum policy, teachers directly translate policy into classroom practice, making their resistance a critical barrier. Other options represent external influences, whereas teachers are internal to the educational process.
