If you want to see an arts teacher go ballistic, mention an interdisciplinary course where the arts would be taught as part of history or literature. They believe that arts teachers will lose their jobs and that the arts will be inadequately taught by English or history teachers. Additionally, arts educators have been trained either as performers themselves or to identify talented students who will carry on the great traditions of performance and production. In this they are not alone, either among educators or the public. They are essentially a moonshot, which may not be entirely attainable in practice.
Curriculums are the means of getting to the vision.
Theoretically, curriculum and instruction can be whatever they want to be so long as students make progress toward the standards. The oversight committee had plenty of vision, as well as an agenda of its own. Many members believe that to anchor the arts firmly in the curriculum, they must be taught as an academic discipline, not merely quasi-professional training. Not all students are talented, but all can appreciate and understand the arts as essential components of being human. The arts should be taught as separate subjects with their own conceptual frameworks, but also in conjunction with other subjects.
