Proposed in the modem education media, the teacher reasonably chooses and utilizes the science teaching process through the teaching design which multimedia technical and the traditional teaching method organic synthesis forms, all played to the curriculum and the teaching method reform the positive role. The science uses the multimedia technologies, may avoid the multimedia technologies in classroom instruction application some erroneous zones, the realization teaching effect optimization.展开更多

Generally speaking, the sports industry development is more quickly, but industry the institutions of higher learning. Therefore, the development of the most important operation static combined with the actual conditions, high colleges in the development of the sports industry. In the new economic mechanism, athletics industry of the school should give up the traditional concept, and the development prospect. All university has its own characteristics, so the university should explore related market according to the resources advantage and appropriate management pattern, form a and the characteristics of college sports industry.展开更多
