Bobbitt took an activity approach stating, "a series of things which children and youth must do and experience by way of developing abilities to do things well and make up the affairs of adult life." (Ornstein & Hunkins, 2013, p. 77)
Bobbitt set out to create a set of curriculum for the elementary grades.
Charters viewed curriculum as goals students must reach.
Charters wanted curriculum makers to, "apply clear principles in order to select materials that would lead to achievement of specific and measurable objectives." (Ornstein & Hunkins, 2013, p. 77)
Caswell saw curriculum making a way to help teachers create instructional activities to meet students needs and interests.
Caswell describes curriculum as, "guides teachers should use in planning their daily lessons, bot as plans they should follow in detail." (Ornstein & Hunkins, 2013, p.80)
