试论现代教学设计理论体系

教学设计应该是一门应用性学科,是如何将教育教学理论、学习理论、传播学理论、系统科学等基础学科的研究成果应用于设计教学系统的学问.教学设计理论的研究对象不是教学系统的性质,而是教学系统的设计方法;教学设计的过程应该是一个创造性地解决教学问题的过程.能对教学现象具有较强的解释能力,能提供发现教学问题、分析教学问题和解决教学问题的方法;能提供控制教学的方法和手段;能提供寻找解决教学问题新方案的方法.     

本体论视野中的教学演化:一种新的教学史观

作为一种人为的存在 ,教学在历史中发生、存在和演化。在以往的教学论研究中 ,教学演化问题一直未能真正进入理论的视域。在教学本体论研究中 ,教学演化作为教学存在的基本形式和基本表征 ,处于极其重要的理论地位。教学演化问题的研究在研究主体、研究对象、思维方式和研究结果等方面与以往的研究截然不同 ,教学演化的方向性、教学方式的演变、教学系统的发育、教学进化史、教学史观等相关理论问题 ,构成了教学演化问题研究的主要论域。教学演化问题的确立以及就此而展开的深入研究 ,在理论上预示着一种新的教学史观的形成     

试论体育教学最优化

教学最优化是教学论研究的出发点 ,也是教学论研究的最终归宿 那么 ,什么是教学最优化 ?教学最优化的标准又是什么 ?在体育教学过程中 ,如何才能实施教学最优化 ?这都是下面要探讨的问题 1　教学最优化的概念教学最优化问题 ,并非今天才提出来的 ,实际上整个教学论所研究的 ,归根到底都是教学最优化的问题 ;而今天的教学最优化问题是在这样的背景下提出来的 :一方面由于蜂拥而来的知识、情报 ,使教师和学生的负担越来越重 ,这就要求教学论提供更为有效的理论和方法来解决这个问题 ,另一方面是由于现代科学技术 ,特别是系统论、信息论、控…     

教学是一种特殊形式的交往

教学的本质问题是教学论中一个极其重要的问题。从其独特的交往目的、主体、信息、介质、关系来说，教学是一种特殊形式的交往。研究教学交往本质对于教学论学科的发展、教师和学生的成长以及教学质量的提高有着深层的意义。     

新课程理念下的数学问题教学

本文从问题教学的前提、问题教学的保证、问题教学的有力保障、问题教学的目的四个方面结合实例对数学问题的教学进行了探讨。     

师范生教学技能训练探新

师范生实习过程中出现价值取向表浅、教学设计形而上学、教学手段单一落后、教学视野狭窄和缺乏教学机智等问题,这既是教学新手的共性,同时也反映了师范生培养过程中的缺乏教学技能训练的深层次问题。提高师范生的教学技能应采取价值取向调整、加强教学分析训练、教学模拟训练、微格教学训练和使用教师成长记录袋等手段。     

问题教学的实施

本文主要阐述了问题教学的实施所需的环境、条件、策略以及问题教学的实施对教学改革的影响.大学教学中实施问题教学,可以吸引大学生深入参与教学,促进大学教学改革的深化,提高大学教学成效.     

反思性教学的两个问题链（下）

二、反思性教学操作的问题链 既然反思性教学是具有反思性质的教学实践而不是一种教学的方法，那么，其操作问题并不是一个反思性教学模式问题，而是一个教学反思的操作思路问题。我们认为，无论反思是发生在教学过程之前、之中还是之后，无论是对教学目标的反思还是对教学手段的反思，都存在着一个内在的教学反思的逻辑。本主要关注教学行动的反思操作，以此为例，说明’一个教学反思逻辑的客观存在。我们发现教学行动反思逻辑的展开，就是一个问题链：“我做了什么——我的做有效吗——我的做自身合理吗——我还能怎样做。”     

问题教学在中学数学中的运用

问题教学是一个创新性的教学。结合中学数学的具体实践,论述了问题教学的提出、意义,问题教学的具体操作过程以及问题教学需要注意的问题。     

“问题解决”教学要注重“三性”

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. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.

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.

胡主席在印度,我却在中国

Today, Sunday morning, I sit thinking and typing at my computer. My thoughts are in my homeland, India and my body is in China. The body is here and mind there for a good reason. Mr. Hu is president and I am resident and both are in each other's countries (what a difference the absence of one small letter makes!). Mr. Hu will return in a few days and I will stay on longer.
