Recently, Constructivism that is expansively accepted to the subject matter is regarded as `an alternative epistemology of education` and an educational basic philosophy or a folk theory of teaching-learning. Constructivism is a theory for the knowledge as a domain of philosophical concerns, and for the perception system. After `60s and `70s behavioralism was transformed into various types of structuralism and cognitivism in philosophical speculation. In these days, epistemology evolved and formed constantly was informed us for the systematic theory. Generally speaking, the concept of constructivism is defined as a subjective understanding for the learner`s reality because of transforming or developing into a structural of cognition That is, constructivism re-structurizes transcendental cognitive structural to establish one`s cognitive learning model or personal understanding model as, in particular, a personal`s cognitive form, for the subject of learning, reality, and it explains for the essential of knowing(learning). In a traditional teacher-centered education, a knowledge is regarded as transmissions from teacher to students, but in a constructivistic perspective, it isn`t like that, but is informed for making for themselves by the subject of cognition. Also, the new 7th national curriculums key concept is a differentiated curriculum, open education, etc. It`s background theory is constructivism, and in educational research a student-oriented individual learning, a reflective teaching-learning, an authentic assessment, a portfolio assessment, a performance assessment, a cooperative learning, etc. are based on constructivism. It`s expressive adaptation is tried to the subject, which is not established in physical education. Further more research has not been conducted yet. Therefore, it is requested that understanding reality for physical education in Korea, in addition to making a diagnosis and developing practical domain and change and orientation for form be become nowadays. The main purpose of this research is to understand the value of constructivism to, know that it is a paradigm of physical education, which is possible to adapt in physical education, and to try to present orientation of constructive teaching-leaning in physical education. As mentioned above, constructivism is based on a principle of the self construction, a principle of the viability of the knowledge, and a principle of the non-objectivity. The subjective independence is usually regarded as an objectivity on radical constructivism: it is regarded as a common subjectivity, and is comprised sociality, cooperative spirit in social constructivism. On the assumption of these three principles, the teaching-learning principles of constructivism can be led as follows: ① the principle of individualizing (student-central), ② the principle of interaction(social), ③the principle of activity (meaning-oriented), ④the principle of abstraction (reflective). In general, `constructivism is neither a new concept, nor a best theory`. It is only `useful penetration` as an educational alternative epistemology to reform, and is a background theory in education and teaching-learning theory to change the mainstream. In conclusion, this study demonstrated that constructivism was presented as a theory for the problem-solving, correcting an error, and changing the problem in physical education.
