Subject-centered curriculum design describes what needs to be studied and how it should be studied. Core curriculum is an example of a subject-centered design that can be standardized across schools, states, and the country as a whole. In standardized core curricula, teachers are provided a pre-determined list of things that they need to teach their students, along with specific examples of how these things should be taught. You can also find subject-centered designs in large college classes in which teachers focus on a particular subject or discipline.
