本书是Epstein教授研究和指导家校合作工作的代表作和集大成之作."家校合作"是国内的提法,在国外(以及在本书中)对应的概念是"学校、家庭(和社区)合作伙伴关系"(School,Family,and Community Partnerships).
这是一本写给美国教师、家长、校长和各级教育行政领导阅读的关于家校合作的经典工具书.无疑,从书名就可以看出,这是一本指导学校如何开展家校合作活动的行动指南,是按照家校合作的行动者的实践逻辑展开的,提供了详尽的、一步一步的家校合作行动策略.书中详细描述了美国、加拿大家校合作的实践框架、组织架构、制订计划与实施,对活动组织参与者的专业培训,分幼、小、初、高各学段和学校、学区和州各个行政层次的行动和责任特点,教师必须具备的有关专业知识、能力和工作内容,如何评估和选择有效的家校合作活动等等,具有很强的、系统的实践指导性.展开更多

With the mode of human production developing into the stage of capitalism, there seems to exist a magical power, which has been producing an immense amount of material wealth and garbage, while turning the mankind into property owners and proletariat. They are both the inevitable results of the capital’s logic, i. e., pursuing the maximization of its profits, and the facts of struggling against the capitalism. It has been turned out that the developed capitalist countries in the west led by the U. S. are the wildest destroyers of the environment and natural resources. Some theories on the issue shun this fact intentionally or unintentionally. Therefore, they fail to grasp the essence of the issue, nor are they able to find out the historical way of solving the “environmental problem”. This paper draws a conclusion that capitalism is doomed to destruction, which is not only our lesson taught by the issue, but also the only road to resolution for the issue.展开更多

文摘Environmental problems and material wealth are the two counterparts of man-made nature, as well as two poles of natural division resulted from the human productive activities. With the mode of human production developing into the stage of capitalism, there seems to exist a magical power, which has been producing an immense amount of material wealth and garbage, while turning the mankind into property owners and proletariat. They are both the inevitable results of the capital’s logic, i. e., pursuing the maximization of its profits, and the facts of struggling against the capitalism. It has been turned out that the developed capitalist countries in the west led by the U. S. are the wildest destroyers of the environment and natural resources.
