The analysis was carried out using a key issues dossier based on school science, which not only provides a description of reality, but also introduces a theoretical explanatory framework. Regarding species diversity, we focused on the descriptive approach, considering the link between diversity and trophic relationships, ecological succession and ecosystem stability through change, consequences for biodiversity of human activities and mechanisms to face such consequences; and on the explanatory perspective, which provides an interpretative answer for all the aspects previously mentioned. The findings drawn from textbooks show that biodiversity is linked both to the study of the ecosystem and to the impact of human societies on its maintenance. However, such study is particularly focused on the descriptive, rather than on the explanatory level. So, teachers should improve the study of biodiversity foresting a balance between descriptive and explanatory level.展开更多

What person, how to cultivate people is developing the socialist education enterprise in our country must solve fundamental problem. College students is a national valuable human resources, are the hope of nation, the future of our motherland. To make university students grow up to be the cause of socialism with Chinese characteristics qualified builders and reliable successors, we not only need to vigorously improve their scientific and cultural quality, and actively improve their ideological and political quality. College students＇ ideological and the political education content system of the science building is refers to according to the requirements of college students＇ ideological and political education goal, to constitute elements of ideological and political education content should be reasonable configuration, make each other, permeate each other, in order to realize the content of organic integration and collaborative development.展开更多
