敢问不难，善问不易——对小学语文课堂中质疑现象的思考

曾经的语文课堂，是以老师提出的问题为主线，以学生顺利解答这些问题为完成教学任务的标志。提问的权力在教师的手中，学生是围绕教师设计的问题展开学习与思考的。如今，在新课程理念的指引下，教师把质疑的权利还给了学生，引导学生在学习的过程中发现问题，提出问题，分析问题，解决问题，激活了学生的创新思维，有利于学生的主动探究。     

创新阅读教学四法

问题法问题法，即在教师的指导下，以问题为核心，让学生不断地阅读课文，不断地寻找问题，不断地发现问题，不断地提出问题。学生提出问题后，教师可组织引导学生评论：哪些问题提得好，哪些问题对大家有启发，哪些问题最新颖，哪些问题最富于挑战性，哪些同学发现的问题最多，等等。对于学生提出的诸多问题，教师可以有目的地选择部分问题和学生共同分析、研究、解决。因为“问题法”本身注重的是通过发现问题和提出问题去培养学生的创造力。使用“问题法”教学，教师必须十分注重培养学生的问题意识。首先，要鼓励学生敢疑敢问。对学生提…     

置境激情 交互共振 共生成长——浅谈初中思想品德课教学中有效学习情境的创设

一、通过提问题创设问题性情境 问题性学习情境就是有助于学生自主学习，教师创设或在师生学习共同体中师生共同创设的，以问题方式呈现和营造的学习情境。它是根据教材内容和学生的认知状态，在学生“山重水复疑无路”时适当设置一些富有启发价值的问题，把学生导入“最近发展区”，给学生搭建“脚手架”，让学生积极主动的思索，然后发现“为什么”，最终找出问题的结果。     

如何调动学生的主体参与意识

问题是思维的源泉，思维经常是由解决问题开始的，没有发现问题，就无从思维。因此，在教学中教师要善于向学生提出问题，尽可能利用语言情境、思维情境、实验情境给学生创设疑问，诱导学生发现问题，强化学生产生问题，鼓励学生多问问题，让学生成为问题的主人，从而达到启发思维，引导学习的目的。如在《生活中的圆周运动》一节的教学中，一方面让学生自己动手做演示，观察物理现象，另一方面让学生写出观察现象后所想到的问题，而按照逻辑思维的形式，可在学生头脑中产生一系列问题。

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.
