初中生物学课程的理科属性主要体现在实验教学上,因此以各种实验为手段开展生物学教学是彰显生物学理科特征和学科特点的有效方法。在生物实验教学中把演示实验和学生分组实验以及探究实验有机结合的同时,注意把实验内容生活化,不仅能... 初中生物学课程的理科属性主要体现在实验教学上,因此以各种实验为手段开展生物学教学是彰显生物学理科特征和学科特点的有效方法。在生物实验教学中把演示实验和学生分组实验以及探究实验有机结合的同时,注意把实验内容生活化,不仅能够彰显生物理科属性,而且能够激发学生学习生物学的浓厚兴趣。 展开更多

This study examines the socio-spatial context of uneven development and the residential accessibility of green space in Dalian of Liaoning Province, China. The social fairness was analyzed with a community scale as the basis. We combined social scientific methods with a GIS method using a behavior accessibility model from the perspectives of fairness of urban green space allocation based on social geography, geographic information science, management science and many other related discipline theories. The results show that: 1) Most of the urban green space distribution presents an unbalanced phenomenon, and it does not match with the population distribution; 2) We found some differences in the accessibility of the population with different attributes and opportunities to use and enjoy the urban green spaces, mainly due to: the dual social and spatial attributes of the residents and the serious stratum differentiation generated were the internal causes; the residential space differentiation and the pursuit of economic and real estate development were the direct causes; and unreasonable planning, in regard to the fact that government policies did not give consideration to efficiency and fairness, was also an important factor. 展开更多
