写作活动是由文章、世界和主体这三个元素构成的,主体是最活跃的、具有决定意义的元素。写作主体的结构是一种典型的耗散结构,它必须依靠和外部世界不断进行信息能量的交流才能保持自身的活力。在写作教学中,我们组合的信息就是用来激活主体结构的问题情境或具体对象,目的就是使主体结构远离平衡,从而促进新信息的产生。 Writing activities are composed of three elements: the article, the world and the subject. The subject is the most active and decisive element. The structure of the writing subject is a typical dissipative structure, which must maintain its vitality by constantly communicating with the outside world through information and energy. In writing teaching, the information we combine is the problem context or specific object used to activate the subject structure. The purpose is to keep the subject structure away from balance and to promote the generation of new information.
