说课也要“说学生”

目前说课一般包括四个环节:说教材、说教法、说学法、说教学程序。但我们在教学实践中逐步认识到,仅有这四个环节是不够的,说课也要“说学生”。“说学生”与“说学法”看似相同,实则有区别。“说学法”,即教会学生如何学习,而“说学生”则除了教学生学习,还要考虑全面提高学生

“照着说”与“接着说”——“文气说”的现代转型模式探讨

“文气”是中国古论的一个重要命题,在今天有关古代文论的现代转换中仍有着重要的现实意义。对于“文气”说的现代转型,可参照冯友兰先生在他的《新理学》中提出的“照着讲”与“接着讲”模式,先从继承古代优秀传统方面来“照着说”,对“文气”说的历史作一回溯;在此基础上,再“接着”说,关注现代语言模式、文学形态的演变,在原有的概念、范畴里注入时代精神,同时也可与西方相关的文艺理论进行对接。在转型过程中特别要注意保持“文气”说的诗性之思的特点。     

中国古代的主脑说与主心说

中国古代主脑说与主心说几乎是同时产生的。但在明代以前数千年中，主心说一直居于主导地位，并形成了心脏定位说与五脏定位说两大学派，直到明代医学家李时珍提出“脑为元神之府”这一著名论断开始，主脑说才逐渐取代主心说而居于主导地位。经明清的方以智、刘智，最后以王清任的“脑髓说”的诞生而宣告了主脑说的最后胜利

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.
