Subject-centered curriculum design revolves around a particular subject matter or discipline. For example, a subject-centered curriculum may focus on math or biology. This type of curriculum design tends to focus on the subject rather than the individual. It is the most common type of curriculum used in K-12 public schools in states and local districts in the United States. Subject-centered curriculum design often revolves around what needs to be studied and how it should be studied. Core curriculum is an example of a subject-centered design. This type of curriculum is standardized. Teachers are given a set list of things that need to be studied along with specific examples of how these things should be studied. You can also find subject-centered design in large college classes where teachers have a tendency to focus on a particular subject or discipline with little regard for individual learning styles. The primary drawback of subject-centered curriculum design is that it is not student-centered. This form of curriculum design is less concerned with individual student needs and learning styles compared to other forms of curriculum design, such as learner-centered design. This can cause problems with student engagement and motivation and may even cause students to fall behind in class.
