The proposal of "Healthy China" strategy putsforward higher requirements for College Physical Education teaching. At the same time, the popularization of scientific andtechnological achievements in sports colleges and universities has also resulted in one. Therefore, the author studies the impact ofthe popularization of scientific and technological achievements in sports colleges and universities from the perspective of healthyChina. College physical education should be guided by the "healthy China" strategic goal, change the teaching concept, improvethe teacher's own quality, reform the curriculum and evaluation system, cultivate students' health awareness and exercise habits,and then improve the overall quality of students' sports. It can promote the further development of the popularization of scientificand technological achievements in universities.展开更多

A potential solution to address this is to recognise the need for greater relevance-relevance to the curriculum, to the needs of society and, in the eyes of the students. The paper tries to puts forward a rethink of the philosophy for school chemistry education, based on the underlying belief that chemistry education is an integral part of education. The target is labelled scientific and technological literacy for all (STL). STL rejects the notion that chemistry is taught solely to acquire the abilities to be a scientist and supports the vision of a single curriculum goal, applicable to all students. Besides being a philosophy, STL is also a teaching approach. This approach is to initiate the teaching of chemistry topics, starting from a carefully chosen society perspective and to introduce the conceptual learning on a need-to-know basis. A limitation is the professional development of teachers. Suggestion for overcoming this involve workshop on materials development. A concern is expressed in cases where teachers make use of ready-made teaching materials (a common practice), without first gaining an understanding and an appreciation of the intended philosophy related to these materials.展开更多
