Given the fact that the development of key competences of physical education discipline plays an important role in nurturing students' key competences, the current study is designed to give a close observation on characteristics of physical education, exploring into the method of identifying every dimension of key competences and their level of development in physical education and meanwhile making corresponding reasonable explanation. The methodological analysis of identifying indicators of key competences of physical education discipline cover several aspects, including theoretical preconditions, a theoretical framework and the way applied to identify the indicators. It is found in the study that the identification of key competences should abide by a principle of being concise, influential and concordant as well as a combination between quality and quantity. Besides, the operability, measurability, weights among indicators and development levels of different indicators should all be taken into consideration. It is hoped that the study can be helpful for improving the assessment technology and the standard system in identifying indicators, which will enable it possible to better describe, explain, monitor, predict and finally improve students' key competences of physical education.

Against the background of the world and the international practice in physical education, the current research explores into the values connotation and realization path of developing key competences in physical education from the perspectives of integration degree, ways of interaction, development of roles, orientation of goals, value orientation and ways to explore the potential etc. It is found that the unique nature of physical education makes it an ideal way to develop key competences. And it is of great necessity for educators to explore deeply the intrinsic value of sports and respond fully to the value pursuit of sports attributes, which is an important support for the development of key competences. The transformation and implementation of key competences in physical education can be realized by educators through infiltrating effective humanistic concern, implementing scientific structural reform and exploring learning pathways of different skills.
