论教学理论介入教学实践的路径与价值

教学理论与教学实践脱离之根本在于教学理论工作者与教学实践工作者之间的隔阂。破解教学理论与教学实践的"两张皮"难题,需要教学理论工作者与教学实践工作者的团结协作。站在教学论学科立场上看,教学理论必须从关注教学实践走向介入教学实践。教学理论要介入教学实践的根本原因在于教学论学科所具有的双重性格,即教学论既具有理论性,又具有实践性。教学理论介入教学实践有四种基本的方式与途径:一是教学理论工作者将教学理论带入教学实践;二是教学实践工作者到教学理论工作者那里"取经";三是在区域性的教育实验中教学理论工作者与教学实践工作者的合作;四是国家宏观教育改革过程中教学理论工作者与教学实践工作者的合作。教学理论介入教学实践的价值在于发展教学理论,有效推进教学实践。     

教学限度：一个需要探究的话题

所谓教学限度,是指教学思想、教学方法、教学手段、教学目标、教学效果等与教学有关的内容或要素,在教学实施中,具有适用性、有限性、局限性。教师在教学过程中不要超越教学限度,要有效地控制教学要素的容量、进展,实现教学要素的有机组合,以取得最优化的教学效果。教学限度不是某个具体的数值,而是一种临界的状态。与教学限度相对的概念是教学过度或教学无度。     

基于教学目标的有效教学策略

有效教学是对中小学落实课程标准的要求,也是对教师具体教学行为的要求。所以说,教学是否有效,关键在教师。目前,很多教师对有效教学的理解存在偏差,对有效教学与教学目标之间的关系认识模糊,导致教学随意化、去目标化等现象的发生,影响了教学的效果。基于教学目标实施教学是实现有效教学的重要途径,主要策略有：理清教学目标与课程标准、教科书之间的关系,确定教学目标;科学选择和组织教学内容,有效承载教学目标;分析学情,为有效达成教学目标奠定基础;以教学目标统领教学过程,有效达成教学目标;基于教学目标进行教学评价,保证教学目标的有效达成。     

教学想象的审美阐释及提升策略

教学想象是课堂教学中一项蕴含艺术性的活动,富有想象的教学过程会促成教学美。教学想象中蕴含的美是基于教学构成性美的综合考量,包括要素、过程、形式与风格的美;它是指向教学生成性美的全面激发,表现在教学动态生成与发展中。教学想象之美表现为:借助教学想象达成教学目标的优化;依托教学想象实现教学内容的活化;凭借教学想象彰显教学主体的互动;依仗教学想象呈现教学过程的创生。为构建教学想象美化教学,需通过教学想象之外制定适切的教学目标,实现教学形式美;教学想象之内使教学内容充满活力,确保教学内容美;批判已有教学想象给师生留有深度想象的自由,达成教学过程美;教学想象之上充实教学活动,提高教学审美的品位。     

论教师教学惯习的强化与变革

教学惯习是对教学要素结构化的产物,教学惯习对教学要素的吸纳、粘滞和锁定,形成了教学惯习的自我强化机制,使教学机智所需的教学要素被阻断。教师要对被教学惯习吸纳的教学要素施行变革,让教学要素重新流动起来,这种变革的动力来源于未被教学惯习吸纳的唯一教学要素也是最重要的教学要素——学生。让所有的教学要素回归到学生主体上,使学生来聚合所有的教学要素,这样,被吸纳的教学要素才能重新在师生中流动开来。     

高中生物新课改呼唤优质教学

新课程呼唤有效教学和优质教学,有效教学是对教学的基本要求,优质教学是追求的目标;有效教学未必是优质教学,而优质教学必然是有效教学,优质教学是更高层次的有效教学。在高中生物教学中,课程改革的理念是优质教学出发点和归宿点;提高学生生物科学素养是优质教学的根本目标;课程三维目标是优质教学的导向点和评价点。     

教学目标综合征的会诊与治疗

众所周知,一份完整的教学设计一般应包括教材分析、教学目标、重点难点分析、教学准备和教学过程等。当然,教师还可以把课后反思也纳入教学设计中。在教学设计的这些要素中,教学目标和教学过程是最基本的内容。然而,实际教学中,有些教师却常常忽视教学目标的重要作用,违背教学目标的设计原则,设计出许多随意和难以操作的教学目标。     

论教学理念的操作转换

教学理念是人们为了某种教学的利益、在一定的教学理论认识基础上形成的关于理想教学的基本观念。教学理念和教学实践是性质不同的两个系统。教学理念表达教学的理想,教学实践寓于教学的现实。教学理念,通过一定的渠道,走向教学实践,这就是教学理念的操作转换。教学理念的操作转换分为以下步骤：发现教学理念中的教学思维,从教学思维中演绎出核心教学行为,分析教学行为对教师专业素质的要求。     

基于教学学术的高校在线教学创新

教学学术和在线教学都是高等教育的新兴事物,两者存在着内在的关联。教学学术是一种以教学为对象的学术活动,信息技术推动了高校在线教学的多样化发展。信息化时代,教育技术向教学领域延伸,线上教育的复杂性对高校教学的开展形成了挑战。基于教学学术的在线教育,表征着高校教学的发展方向。通过信息技术,高校教学实现了从“课堂教学”到“直播教学”的转变;通过教学学术,高校在线教学还将实现从“技术”到“学术”的升华。在线教学创新,既是技术进步的结果,也是教育高质量发展的需要。高校教学创新发展的路径是运用教育技术改进在线教学、以教学学术提升教学品质。高质量开展线上教学,依赖于教学学术和在线教育的深度融合。     

教学细节范畴论：概念、本质与特征

＂教学细节＂是一个理应得到重视的教学范畴。教学细节指的是学校教学过程中发生的、对教学具有一定影响的最基本的教学要素或教学行为。本质上看,教学细节是一种微型教学事件。把教学细节视为微型教学事件,有助于重视、提高教学细节在教学中的作用,增强教学细节设计意识;有助于用联系的观点看问题,在教学过程的整体中研究、优化教学细节。教学细节具有指示性、微型化、生成性和情境性特征。

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.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.     

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.
