The purposes of this study were :(1) to investigate the attitudes of the elementary school teachers, the teacher college professors, and the educational administrators on the feasibility of implementing the whole-class or the subject-separated teaching in elementary schools; and (2) to explore the college professors opinions about the way to change the organization and the curriculum of the college to gear with the classroom teaching models in elementary schools. The whole-class teaching refers to a teaching model in which there is only one teacher to teach all or most of the subjects in a class. A subject-separated teaching refers to a teaching model in which there are many teachers to teach different subjects in a class, and every teacher teaches only one or two subjects based on his major. The subjects of this study were 1200 elementary school teachers, 265 teacher college professors and 115 educational administrators. The “Inventory of the Teaching Models for the Elementary schools” developed by the researchers was conducted.
