素质教育观念下课堂设计的新审视

素质教育是当前课堂教学改革的主旋律。课堂教学素质化以面向全体学生，发展学生全面素质，让学生主动、生动活泼地学习为主要特征。近年来，广大教师对课堂教学的素质化作了不少有益的探索和尝试。但笔者感到，当前的课堂教学设计还普遍存在滞后于素质教育思想观念的现象，从而影响了课堂教学素质化的落实。课堂教学设计决定着课堂教学的行为，从某种程度上讲，有什么样的教学设计，就有什么样的课堂教学行为。落实课堂教学的素质化必须从课堂教学设计入手。课堂教学设计包括教学目标、教学重点和难点、教学策略、教学媒体等因素，本文拟就素质教育观念下的这些设计作新的审视。     

如何进行教学结构的设计

教学的最基本环节是集体授课模式的课堂教学。因此，教学设计不可避免地要进行课堂教学设计。要进行课堂教学设计又必须进行课堂教学结构的设计。课堂教学结构的基本要素是教师、学生、教学内容和教育媒体，那么，如何使这些要素有机地结合，形成最佳结构。取得最优教学效果，就是课堂教学结构设计的任务。

关于学案设计的几点思考

实施学科课堂教学创新教育，课堂教学设计的改革是关键。课堂教学设计既要体现教师的教学理念，又要反映对教学内容的处理和教学方法的选择；课堂教学设计还直接影响着课堂教学的具体实施过程与效率。因此，课堂教学的改革，要在设计上下功夫。传统教学设计所形成的教案，主要是从方便教师“如何教”的角度入手，确定教学的重点、难点，安排教师的教学活动过程。陶行知先生说：“学生学的法子，就是教的法子。”当代教学倡导以学为本，要求教要为学服务，树立知识是学生在教师指导下自己学会，学生是学习的主体，要培养学生的自我学习、自我…     

小学教师关于课堂教学设计能力形成与发展的反思

一、问题的提出 课堂教学设计能力是教师课堂教学所需的基本能力，教师课堂教学设计能力的发展直接影响着教学的质量和水平，任何教育目标、教育理念、教材设计思想都要通过教师的课堂教学实现。而课堂教学设计就是为了支持学生有效地学习而预先对教学所进行的规划和组织，其目的是通过创设学与教的系统帮助学生达成预期目标。在前一个研究中，我们通过对小学教师授课教案的客观评价发现了小学教师课堂教学设计能力发展的特点，小学教师在分析教学任务、选择教学方法、教学结果的评估三方面发展较好，制定教学目标和分析教学对象以及选择教学媒体和手段方面的能力发展相对滞后：还发现影响小学教师的教学设计能力的主要因素是教师学历和所在学校的水平，说明教学能力是一项实践性的能力，它的发展既受基础学历的影响。

阅读教学的即时决策与行动——谈小学语文阅读中的教学机智

教学设计可分为课堂教学准备的“前设计”、课堂教学实施的“中设计”与课堂教学反思的“后设计”三个阶段。“前设计”对于教学来说意义与价值不可忽视。传统的教学设计主要研究的是课堂教学的“前设计”。但是教学只停留于“前设计”，既剥夺了学生的主体地位又限制了教师的课堂发挥。课堂“中设计”正是体现着教师灵活的教学机智，

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet.

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.
