The discipline-based content design option focuses on a strict interpretation of the disciplines with separate subjects in separate time blocks during the school day. No attempt for integration is made, in fact, it is avoided. Traditional approaches to subjects such as language arcs, mathematics, science, social studies, music, art, and physical education are the usual fare. In secondary programs, these general academic and arts areas break down into more. specific fields, such as algebra under mathematics or American history under social studies. There are some variations of block scheduling and the way the week or cycle is programmed. Nevertheless, knowledge is presented in separate fields without a deliberate attempt to show the relationships among them. (p. 14}
