The result shows that: with the expansion of teacher education space, the reform and development of Chinese teacher education is much closer or equal to that of the international teacher education. The transitional stage and education reform in China puts forward a new demand for P. E. talents. The innovation as to education object, specification and curriculum arrangement raised in P. E. Curriculum Arrangement for Chinese Universities with four-year Program published in 2003 meets such a demand, and narrows the gap of education development in high P. E. academy between China and foreign countries. P. E. teachers abroad are usually cultivated by comprehensive universities, the cultivating objectives are verified, and generalists adapted to social development are emphasized. Cultivating mode abroad are various, with "open-type" or "non-directional type" as the main mode, and 4-year program, 5-year program, and 3-year program serve as the main form of education system. Curriculum arrangement abroad stresses general education, with foundationalization, normalization, objectification, optionalization, miniaturization, internationalization and syntheticalization as its characteristics and it employs credit system. The close-typed cultivating mode of P. E. academies in China should be gradually transformed into open-type or multi-type, cultivating generalists instead of specialists, and further constructing a new one with several cultivating types co-existing. Orientation of P.E. teachers in China should follow standard principle, coordination principle, experience principle and resource principle. To improve P.E teacher education in China, the following measures can be taken: relevant laws and regulations should be made for orientation; P.E teachers" training organization should be encouraged to participate in orientation; extension and connotation of P.E. teacher education should be expanded; resources should be optimize; systematic P.E. teachers" orientations should be organized;"Life P.E. Teacher Qualification "should be changed; useful-life should be set for P. E. teacher qualification; P.E. teacher qualification should be regularly authenticated; On-job training of P. E. teachers abroad tends to be systematic, but in China P.E. teachers" on-job training and prevocational training are separated; therefore measures must be taken to change this circumstance and thus speed up the systematic process. Factors concerning constructing a new system of P. E teachers are the following: reconstructing resources, making P.E. teachers" cultivation, orientation and training systematic, establishing a mechanism for encouragement and punishment, making school-based training and college training systematic, and setting up a mechanism combining directional training with non-directional training.
