These three areas reflect the organization of most teacher education programs in North America as well as Asian countries like Sri Lanka. Courses, modules, and other activities are often organized to belong to one of the three major areas of teacher education. The organization makes the programs more rational or logical in structure. The conventional organization has sometimes also been criticized, however, as artificial and unrepresentative of how teachers actually experience their work. Problems of practice frequently (perhaps usually) concern foundational issues, curriculum, and practical knowledge simultaneously, and separating them during teacher education may therefore not be helpful.
