Who else should be involved in the curriculum design?

Topics, areas of study, or more specific types of things (since you use the term "design")?

If areas of study, I think philosophy should be added. Lower education (I actually mean high school most especially) hits Math, Reading, & Writing. The most important topics. But philosophy is an area that is not really available until College and I think it is just as fundamental (thinking about truth, reality, and the philosophy of science and inquiry). Psychology is another area that should be a bigger part of the pre-college curriculum (tips about learning, coping with stress, Social Psychology).
